Which tweakment do you recommend for under-eye wrinkles?

First, a really good eye cream to hydrate and strengthen the skin, plus a sunscreen during the day to stop those wrinkles getting worse. Then maybe a type of radiofrequency microneedling, or a heat treatment like Tixel, that can be used close to the eyes to rejuvenate the skin, or an injectable treatment like PRP to regenerate the under-eye skin and smooth out the wrinkles. Find a great practitioner in your area, book a consultation and see what they can suggest that might help you.
