Retinol

This is made from vitamin A and is added to creams to go on your skin. It boosts collagen production and plumps out skin, reducing fine lines and wrinkles. It also improves skin tone and color, and reduces mottled patches.

Many dermatologists prescribe retinol’s stronger counterpart, tretinoin, or similar products, to slow skin aging, improve irregular pigmentation, and clear up acne. Over-the-counter products containing retinols may be weaker, but they can still improve skin appearance.

Using a retinol-based product may cause your skin’s top layer (the epidermis) to become dry and flaky. Be sure to wear moisturizer and sunscreen in the morning after you use it, or ask your dermatologist about alternatives.
