Resist 1% Retinol Booster

What it is: A retinol-rich, lightweight fluid that can be mixed into any moisturizer or serum for additional anti-aging benefits to supercharge your skin care routine.

Who it's for: All skin types. Ideal for improving the appearance of skin that is showing signs of aging, deep wrinkles, uneven skin tone and loss of firmness.

What it does: The powerhouse blend of retinol and antioxidants and proven age-fighting ingredients stimulates collagen production, helps fade brown spots and overturns past damage for smoother, firmer skin. The concentrated formula also provides skin-clearing benefits for those struggling with adult acne, and can be applied directly to the skin as a lightweight treatment for those with oily and/or breakout-prone skin.

How to use: Apply once or twice daily after cleansing, toning and exfoliating. Dispense your desired strength (by number of drops) into your favorite moisturizer or serum and apply as usual. For daytime, follow with an SPF rated 25 or higher. It may be applied to the under-eye area. Avoid your eyelids and lips.
