At what age does the skin start to get wrinkles and crowsfeet?

Varies: As early as late 30s to 50s depending on sun exposure, genetics, smoking and nutritional status.

Onset of wrinkles: Wrinkles form naturally over time and are influenced by exposure to sun, smoking, sleeping habits (bunching of skin for long durations), genetics, and repetitive & habitual muscle activity under the skin (like squinting). Spf, sunglasses, good skincare, no smoking, laser therapy, and Botox all can help prevent wrinkles. Hope this helps!

Age of wrinkles: There is no right answer to this question. I have seen some patients with some fairly deep wrinkles in their early 20's. Genetics, sun exposure, diet, smoking all play a part in the formation of winkles.
