Do skincare products protect against sun damage?

While ingredients like Niacinamide and Vitamin E can help repair UV damage, they do not provide sun protection. Always wear broad spectrum sunscreen (SPF 30 or higher) to protect against premature aging and skin cancer. 

This is especially true if you use products like tretinoin and AHA, which can make the skin more sensitive to sun exposure (photosensitization).  

Defy Medical’s skincare products support and repair skin, but they don’t replace sun protection.
