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

  1. Several causes work together. Aging, facial movement, ultraviolet exposure and changes in supporting tissue all shape skin contour.
  2. Fine lines and deep folds differ. Fine lines show more with dryness; deeper folds also reflect volume and structural change beneath the skin.
  3. It is usually cosmetic. Wrinkles are a cosmetic concern rather than a disease.
  4. 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.

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?

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.

Daily care

Daily care for Wrinkles and Fine Lines

Habits that help

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.

Habits to avoid

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.

Limited evidence

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.

Six retinol products lined up, including SkinCeuticals Retinol 0.5, Murad, CeraVe, First Aid Beauty, RoC and Replenix
Moderate evidence

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.

Existing educational treatment illustration: Adapalene
Moderate evidence

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.

Limited evidence

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.

Six vitamin C products on white, including La Roche-Posay, L'Oréal Revitalift, CeraVe, Vanicream, bliss and Olay
Limited evidence

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.

Four glycolic acid toner and liquid bottles lined up on white, one with its box
Limited evidence

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.

Five bakuchiol serums on white, including a dropper bottle with purple flowers, COSRX, Paula's Choice, Herbivore and LAUEF
Limited evidence

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.

Six niacinamide products on white, including The Ordinary 10% + Zinc 1%, Paula's Choice Booster and EltaMD UV Clear
Limited evidence

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.

Four peptide serum bottles on white: two droppers, a pink glass bottle and a white pump bottle
Limited evidence

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.

Five growth factor serums lined up on white, including MUMUK, DRMTLGY, PEPFACTOR, E.G.F. and Allies of Skin
Limited evidence

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.

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. 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. 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. 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. 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. 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 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.

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.
