No purified water or retinol derivatives. Formulated using 0.5% stabilized, pure retinol for powerful anti-aging care.

For intermediate-level retinol users looking for a highly concentrated, youth booster.

Retinol is known to help with fine lines, wrinkles, uneven skin tone, and overall skin texture. It works by increasing cell turnover, promoting collagen production, and unclogging pores. When using products containing retinol, it's essential to start with a lower concentration (like 0.5%) and gradually increase usage to avoid irritation, especially if you have sensitive skin. Additionally, it's crucial to use sunscreen during the day, as retinol can increase sun sensitivity.
