How important is sunscreen in preventing premature aging?

Sunscreen plays a crucial role in preventing premature aging. Here's why:

• Protects Against UV Damage: Ultraviolet (UV) rays from the sun cause up to 90% of visible signs of aging, including wrinkles, fine lines, and dark spots. Sunscreen acts as a shield against these harmful rays.
• Prevents Photoaging: Photoaging, caused by prolonged sun exposure, leads to the breakdown of collagen and elastin in the skin. Sunscreen minimizes this damage, helping skin stay firm and youthful.
• Reduces Risk of Hyperpigmentation: Uneven skin tone and age spots often result from UV exposure. Regular use of sunscreen prevents these pigment-related aging issues.
• Maintains Skin Barrier Health: Sunburn and inflammation from UV exposure can weaken the skin barrier over time. Sunscreen helps preserve skin's natural defenses, keeping it healthy.
• Works Daily, Year-Round: Even on cloudy days or indoors (due to UV penetration through windows), sunscreen is essential for continuous protection.
