Premature aging

Sun Damage Skin Barrier Damage

Photoaging damage: UVA/UVB radiation accelerates the aging process by 3-5 times

Collagen degradation: Ultraviolet radiation increases the activity of matrix metalloproteinases (MMPs) by 80%

Free radical surge: The number of free radicals generated by a single sun exposure increases by 200 times

DNA photodamage: formation of cyclobutane pyrimidine dimer (CPD)
