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. A descriptive term for fine surface lines accentuated by skin dryness.


The same eight facts on every condition comparison.

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.

Dehydration Lines A close side view highlights delicate lines under the eye and across the upper cheek.
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.
Reduced hydration in the outer skin makes fine surface texture more visible. These shallow lines reflect moisture changes rather than necessarily indicating permanent loss of deeper support.
Wrinkles and Fine Lines. Gradually become more visible with adult aging and cumulative sun exposure.
Dehydration Lines. Can appear whenever skin becomes dry.
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.
Reduced surface hydration makes fine texture more visible.
Skin type and how quickly collagen declines are partly inherited.
Moisturizer and a less irritating routine can improve lines related to surface dryness. Persistent lines may reflect established wrinkles rather than dehydration and need a different assessment.
Wrinkles usually deepen gradually with aging and ultraviolet exposure. Sun protection helps limit further damage, and cosmetic treatment may soften their appearance. Results vary, repeat treatment may be needed, and treatment does not stop the aging process.
Fine lines related to surface dryness can soften as hydration and the skin barrier improve. Established wrinkles may remain; worsening irritation is a reason to simplify the routine.
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.
Persistent irritation may indicate eczema or contact dermatitis.
A consultation can help choose suitable treatment. A new rough, bleeding or changing spot should be assessed separately rather than treated as aging skin.
Seek medical assessment for sudden, painful or one-sided change rather than assuming it is ageing.
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.
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.
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.
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.
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.
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.

Use sunscreen, gentle moisturizer and avoid smoking. Choose procedures only after an individual assessment.
