Detailed answer

Sun-damaged skin can be repaired to some extent. The most effective way to repair sun-damaged skin is to adopt a comprehensive skincare routine. This includes using sunscreen with a high SPF daily, applying antioxidants like vitamin C, and using retinoids at night to stimulate collagen production. Additionally, regular use of chemical exfoliants such as AHAs and BHAs can help to remove damaged skin cells and promote the growth of new, healthy skin. It is important to note that while these steps can help improve the appearance and health of sun-damaged skin, prevention and sun protection should always be the primary focus to avoid further damage.
