How to use:
Step 1
At night, after cleansing, apply two pumps of Crystal Retinal to your face and neck. Allow to absorb and then apply a moisturizer. We recommend Advanced Night Restore, which is specifically designed to be used after vitamin A.
Step 2
For new Crystal Retinal users, apply gradually. Use it twice a week for the first 2 weeks, every other night for the next 2 weeks, and then every night after that. You should always use sunscreen the morning after using vitamin A.
Proven to work up to 11 times faster than standard retinol,* retinaldehyde (retinal for short) is a revolutionary form of vitamin A that effectively fights the appearance of fine lines and wrinkles, hyperpigmentation, uneven skin texture, and loss of firmness—without irritation.

Hyaluronic acid
With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the lower layers of the skin to the upper layers. This leaves the skin visibly nourished and supple.
Vitamin E
A powerful antioxidant that provides additional antioxidant protection against the aging effects of free radicals. It also helps enhance the power of vitamin C for optimal visible results.
Glycerin
A natural moisturizer that locks moisture into your skin to leave it hydrated and comfortable.
