Wrinkles and Fine Lines
Wrinkles are creases that form as the skin's supporting framework thins and as repeated movement folds the same spot over and over. A small number of treatments have strong evidence behind them, many popular ones have very little, and nothing available returns skin to how it was.

What is it?
Top things to know about Wrinkles and Fine Lines
- Several causes work together. Aging, facial movement, ultraviolet exposure and changes in supporting tissue all shape skin contour.
- Fine lines and deep folds differ. Fine lines show more with dryness; deeper folds also reflect volume and structural change beneath the skin.
- It is usually cosmetic. Wrinkles are a cosmetic concern rather than a disease.
- Treatment follows assessment. A clinician looks at movement, texture, pigment, volume and skin health, and checks any new or changing spot separately.
What it looks like
What Wrinkles and Fine Lines looks like
Wrinkles form as skin loses collagen and elastic fibers with age and sun exposure. Fine lines are shallow creases, often first seen around the eyes and mouth. Deeper wrinkles develop over time from repeated facial movements and loss of support under the skin. Sun-exposed areas like the face, neck, chest and hands usually show the most change.
Wrinkles are grouped by what causes them. The type guides which treatments help.

Dynamic wrinkles
Appear with movement, like frowning.

Crow’s feet
Fine lines fan outward from the outer eye during expression.

Forehead movement
Horizontal folds appear as the eyebrows rise.

Static wrinkles
Visible even when the face is still.

Sleep lines
From pressing the face into a pillow.

Sun-related fine lines
Fine crisscross lines on sun-exposed skin.
Where it shows up
Facial lines commonly develop around the eyes, forehead and mouth. Neck and hand changes also occur.

Hands and wrists
Hand, finger or wrist locations.
On different skin tones
Wrinkles and Fine Lines on different skin tones
Lighter skin tends to show wrinkles earlier because it has less natural protection from the sun. Brown and Black skin has more melanin and often a thicker dermis, so lines usually appear later and less deeply. In darker skin, uneven tone and dark spots are often the first visible signs of aging.
What happens in Wrinkles and Fine Lines?

Age and sun exposure change the collagen and elastic fibers that support the skin. Repeated folding and changes in deeper support make surface creases more visible.
- Surface lines form: Repeated movement folds the skin.
- Support fibers change: Age and sun exposure alter collagen and elastin.
- Less support deepens folds: Changes below the surface can make lines more visible.
Causes and triggers
What causes Wrinkles and Fine Lines
Causes
Why it happens
Wrinkles form as the skin loses collagen and elastic fibers. Natural aging and sun damage are the two main causes, with sun damage responsible for most visible early aging.
Skin type and how quickly collagen declines are partly inherited.

When it usually starts
When it usually starts
Wrinkles and Fine Lines
Gradually become more visible with adult aging and cumulative sun exposure.
Daily care
Daily care for Wrinkles and Fine Lines
Daily broad-spectrum sunscreen
The best-supported thing here, and it prevents rather than repairs.
Stopping smoking
Removes one of the largest ongoing sources of collagen damage.
Gentle skin care
Use a gentle cleanser and avoid scrubs that leave skin dry or irritated.
Moisturizing
Moisturizer temporarily softens the look of fine lines by hydrating the outer skin.
Collagen-stimulating injectables
Gradual volume improvement, building over months.
Peptide creams
Low-risk addition, not a substitute for a retinoid.
Red light therapy
Small improvements with repeated use, depending on the device's output.
Growth factor and exosome products
Heavily marketed, limited independent evidence in humans.
Oral collagen supplements
Small reported improvements, mostly in manufacturer-funded trials.
Avoid: Unprotected sun exposure
The dominant factor, and ordinary daily exposure builds damage, not only burns.
Avoid: Tanning beds
A concentrated dose of collagen-damaging wavelengths, plus a skin cancer risk.
Avoid: Skipping sunscreen
The neck, chest and hands get the same exposure and none of the attention.
Avoid: Smoking
Damages collagen and elastin, restricts blood flow, repeats the same pursing movement.
Avoid: Squinting
Folds the same lines at the outer eye all day.
Avoid: Sleeping face-down or on one side
Years of pressure crease the cheek in one place.
Avoid: Rapid or repeated large weight loss
Stretched skin does not fully retract, especially after middle age.
Avoid: Heavy alcohol use
Dehydrating short term, linked to more visible facial aging long term.
Avoid: Air pollution
Linked to more visible aging, on reasonable rather than strong evidence.
Avoid: Over-exfoliating
Chronic irritation does not build collagen, and it leaves dark marks on deeper skin tones.
Avoid: Very low body fat maintained over years
Facial fat pads are part of the support structure.
Avoid: A high-sugar diet
Real chemistry, minor factor.
Treatments
Treatments for Wrinkles and Fine Lines

Oral collagen supplements
Trials report small improvements in hydration and elasticity, and most were funded by companies selling collagen. Any real effect is a small one. They are not harmful, and they are not a substitute for sunscreen or a retinoid.

Retinol
The over-the-counter version of the best-evidenced wrinkle treatment. Skin converts it to the active form, so it is weaker and slower than prescription tretinoin, and it takes six months rather than three. That trade is worth it for people who cannot tolerate tretinoin or do not want a prescription. Start two nights a week and build up. Generally avoided in pregnancy — ask your doctor.

Adapalene
A retinoid sold over the counter for acne, and the cheapest way into this class of ingredient. It is better studied for acne than for wrinkles, but it improves fine lines and texture and is often less irritating than tretinoin. Expect less than a prescription retinoid gives. Generally avoided in pregnancy — ask your doctor.

Retinaldehyde
One conversion step closer to the active form than retinol, so it works somewhat faster while still being better tolerated than tretinoin. A sensible middle option for fine lines and texture if retinol has been too slow and tretinoin too irritating. It is less widely sold and usually more expensive. Generally avoided in pregnancy — ask your doctor.

Vitamin C
Used in the morning under sunscreen, it limits some of the day's ultraviolet damage and supports collagen production. The effect on fine lines is modest and slow, and it does nothing for folds or sagging. It oxidises, so a serum that has turned dark orange is no longer doing much.

Glycolic Acid
Regular low-strength use smooths surface texture and softens fine lines, and it helps the dull, uneven look that goes with them. It reaches the outer layers only, so deeper creases and folds are untouched. Used on the same nights as a retinoid it usually causes more irritation than either is worth, so alternate them.

Bakuchiol
Marketed as a natural retinol alternative, and a few small studies show modest improvement in fine lines with less irritation. It is not a retinoid and the evidence is nowhere near retinol's. A reasonable choice for someone who cannot tolerate any retinoid, not a swap for one.

Niacinamide
Well tolerated, cheap, and it helps the barrier and the uneven tone that sits alongside lines. Its direct effect on wrinkles is small. It is most useful here as the thing that lets you keep using a retinoid, rather than as a treatment in its own right.

Peptides
Short protein fragments meant to signal the skin to build collagen. Some small studies show a modest improvement in fine lines, and they are low-risk and easy to tolerate. They are a reasonable addition to a routine and not a substitute for a retinoid, which is far better evidenced.

Growth Factors
Among the most heavily marketed and most expensive serums in this category, often sold alongside exosomes. Independent human evidence for wrinkle improvement is limited, and most trials are funded by the companies selling them. If the budget is fixed, sunscreen and a retinoid come first.

Tretinoin
The best-evidenced cream for wrinkles, with repeated trials showing improvement in fine lines, texture and pigment over three to six months. It works by signalling the skin to build its own collagen, so it thickens the dermis rather than thinning it. The usual failure is going nightly from day one, peeling for two weeks and stopping — two or three nights a week with moisturizer underneath gets far more people to six months. Generally avoided in pregnancy — ask your doctor.

Tazarotene
A stronger prescription retinoid with good evidence for fine lines and mottled pigment. It is more irritating than tretinoin, so it suits skin that has already got used to a retinoid and wants more. It is usually applied less often at first for the same reason. Generally avoided in pregnancy — ask your doctor.

Botox
Botox. The reliable treatment for lines caused by movement — frown lines, forehead lines and crow's feet. It relaxes the muscle that folds the crease, so the line softens over about two weeks and returns as the effect wears off at three to four months. It does nothing for lines that are already there at rest, and nothing for sagging.

Dermal Fillers
Hyaluronic acid gel that replaces volume that has been lost, so it suits folds and hollows — the lines from the nose to the mouth, flattened cheeks, under-eye hollowing. It is the wrong tool for surface lines. Results last roughly six to eighteen months, and the gel can be dissolved if the result is not right.

Fractional CO2 Laser
The strongest result available from a device for fine lines, texture and sun damage, particularly around the mouth and eyes. One treatment usually does it, and the trade is a week or more of raw, red, peeling skin. The pigment risk is significantly higher on deeper skin tones, so settings are lowered, a test spot is done first, and the provider's experience with your skin matters.

Fraxel
Fraxel. Heats columns in the dermis without removing the surface, so it improves fine lines, texture and pigment with a few days of redness and swelling instead of a week of raw skin. It takes three to five sessions to match a fraction of what one ablative treatment does. It is the more sensible starting point on deeper skin tones.

TCA Peel
A medium-depth peel with good evidence for fine lines, rough texture and sun-related pigment, done in a clinic with about a week of peeling afterwards. The deeper it goes the more it does and the more it risks. On deeper skin tones the strength is kept low and a test area is done first, because dark marks afterwards are common at higher strengths.

Ultherapy
Focused ultrasound heats a deep layer to tighten it, aimed at the jaw, neck and brow rather than at lines. The change is modest and takes three to six months to show, and it is nothing like a surgical lift. It can be uncomfortable, and results vary enough that it is worth seeing a provider's own before-and-after photographs.

Sculptra
A collagen-stimulating injectable given as a course, usually three sessions. Nothing looks different straight away; volume builds gradually over several months and lasts around two years. It suits overall thinning and flatness rather than a single line, and it cannot be dissolved, so it is a slower and less reversible decision than filler.

Radiesse
A thicker injectable that both fills immediately and stimulates collagen over the following months, used mainly along the jaw and in the cheeks and hands. It is firmer than hyaluronic acid filler, so it is not used in delicate areas like under the eyes, and it cannot be dissolved.

Microneedling
Fine needles make controlled injuries that prompt the skin to lay down collagen. Improvement in fine lines and texture is modest and builds over three to six sessions. Its advantage here is a lower risk of pigment problems on deeper skin tones than lasers or deep peels carry, which makes it a common first choice.

RF Microneedling
Morpheus8. Microneedling with radiofrequency heat delivered at the needle tips, aimed at the deeper dermis. It does more for early laxity along the jaw and lower face than plain microneedling does, over three or so sessions. The heat is not carried by pigment, so it is comparatively safe on deeper skin tones, and the result is well short of surgery.

Clear + Brilliant
A gentle fractional laser, sometimes called a baby Fraxel, with a day or two of redness. It gives a real but small improvement in fine lines and glow and needs a series to show anything. It is a maintenance treatment rather than a way to change established wrinkles.

LED Light Therapy
Red light produces small improvements in fine lines with frequent, repeated use over months. How much depends heavily on the actual output of the device, and many home masks are far weaker than the ones used in studies. It is low-risk and slow, and it is an add-on rather than a treatment.

Microdermabrasion
Sands off the outer dead layer, so skin feels smoother and looks brighter for a few days. It does not reach the dermis, which is where wrinkles are, so it does not change them. Pleasant, safe on most skin, and frequently sold as an anti-aging treatment when it is not one.

Dermaplaning
A blade scrapes off surface dead skin and fine hair, so makeup sits better and skin looks smoother for a week or two. There is no evidence it affects wrinkles, and it does not make hair grow back thicker. It is a finish, not a treatment.
Outlook
What to expect with Wrinkles and Fine Lines
Wrinkles have no onset and no end point. Timing depends far more on sun exposure and genetics than on age, so what follows is a typical pattern, not a schedule — sun can move the whole thing a decade or more either way. Treatment changes the slope of the line, not its direction.
- 1
Twenties · Roughly 20-29
Collagen production has begun to slow and sun damage is accumulating, but skin still recoils fully. Any lines are dynamic — there with expression, gone at rest. Prevention has the most value now and the least visible reward.
- 2
Thirties · Roughly 30-39
The earliest creases start to persist at rest. Skin looks less smooth in the morning, and uneven pigment often appears alongside.
- 3
Forties · Roughly 40-49
Lines deepen and multiply, and the first volume change shows — slight hollowing under the eyes, flattening of the cheeks.
- 4
Fifties · Around menopause
Skin thickness and collagen fall relatively quickly. Lines deepen over a shorter period than before, dryness increases, and folds become more defined.
- 5
Sixties and beyond · 60 and up
Sagging and folds contribute more than lines. Skin is thinner and more fragile, bruises more easily and heals more slowly, which changes what procedures make sense.
Complications
Complications
- Associated concerns
Lines themselves are usually a cosmetic change. Sun-related ageing reflects cumulative ultraviolet exposure, so a new rough, growing or non-healing spot needs separate assessment.
When to get help
When to get help
When to seek care
A consultation can help choose suitable treatment. A new rough, bleeding or changing spot should be assessed separately rather than treated as aging skin.
Lookalikes
What else could it be?

Dry Skin
Dryness can make fine lines look deeper, then soften after moisturizing. Established wrinkles remain visible even when the skin is well hydrated.

Dark Circles Under the Eyes
Dark circles are a color change or shadow that shifts with the light. Under-eye lines are actual creases you can feel.

Acne Scarring
Acne scars leave separate dents where spots healed. Wrinkles more often form lines related to facial movement and develop gradually over time.
Questions
Questions you might be asking.
At what age should I start treating wrinkles?
Sunscreen as early as possible — nearly all the value is in prevention, and damage accumulates from childhood. A retinoid is reasonable from the twenties or thirties, because it takes months to work. There is no age at which starting stops being worthwhile.
Does anything actually work, or is it all marketing?
Some of it works. Daily sunscreen has good long-term trial evidence for reducing visible aging, prescription tretinoin has repeated evidence for improving fine lines, and botulinum toxin works reliably on lines caused by movement. Lasers, peels and fillers produce real changes. What is oversold is the middle of the market — serums promising results comparable to procedures.
Is tretinoin worth the irritation?
For most people yes, but only if you start slowly enough to keep using it. The common failure is applying it nightly from day one, peeling for two weeks, and stopping. Two or three nights a week, moisturizer underneath, building up over a couple of months, gets far more people to the six-month mark where the results are.
If I stop having botulinum toxin injections, will my wrinkles be worse than before?
No. The muscle returns to its previous strength over about three to four months and the lines return to where they would have been. They can feel worse because you got used to them being softer. There is some evidence long-term use leaves the underlying line slightly less deep.
Do collagen supplements work?
There are trials reporting small improvements in skin hydration and elasticity, mostly funded by companies selling collagen. If there is a real effect, it is small. They are not a substitute for sunscreen or a retinoid.
What is the difference between fine lines and wrinkles?
Mostly depth and cause. Fine lines are shallow surface creases, often more visible when skin is dry, and they respond well to moisturizers, retinoids and resurfacing. Wrinkles are deeper folds involving the dermis, and the deepest are really folds from lost volume underneath — which is why creams do so much for one and so little for the other.
