Crepey skin is thin, finely wrinkled skin that looks a bit like crêpe paper. It often shows on the upper arms, inner thighs, knees, neck, chest and under the eyes. It isn't harmful, but it is one of the clearest signs of sun damage and collagen loss.
What causes crepey skin
- Sun damage: UV breaks down collagen and elastin. This is the main cause.
- Age and menopause, as skin thins and holds less water.
- Rapid weight loss, which leaves stretched skin with less support.
- Dryness, which makes the crinkled texture more visible.
- Some medications, such as long-term steroids, can thin skin.
What helps
- Moisturise daily with a rich cream. Body lotions with urea, lactic acid or ammonium lactate both hydrate and smooth.
- Use a retinoid on the face and neck; on body areas, a body retinol can help over months.
- Apply sunscreen to the arms, chest and legs when they are exposed.
- In-office: lasers, radiofrequency and microneedling can improve firmness and texture.
Most “crepey skin creams” work by hydrating, which plumps skin temporarily. That's still worthwhile, but expect improvement, not reversal.
When to see a doctor
Sudden thinning or easy tearing of the skin, especially with bruising, can be a medication side effect or another condition. See a doctor if crepey skin appears quickly or with other symptoms.
Rosee scans your face on your iPhone and tracks texture, tone, hydration, glow, redness and dark circles from scan to scan, so you can see whether a routine is actually working instead of guessing from the mirror. The photo never leaves your phone. After seven scans it also estimates a Skin Vitality Age, rounded to whole years and never from a single selfie. Every feature is open for your first week, then it is a monthly or yearly subscription.
