FAQs

What is Retinal-MD™ Technology, and how is it different from retinol?
Retinal-MD™ Technology is the most potent form of vitamin A available without a prescription — 11X more potent than retinol. Retinal requires only one conversion step to become active in skin, which helps it work more efficiently than traditional retinol. It helps reduce the appearance of fine lines and wrinkles so skin looks healthier and younger.
Why capsules instead of a bottle or dropper?
Two reasons: dose and stability. Pumps and droppers vary with every application, while each single-use capsule delivers the precise amount of serum your skin needs. Sealing the formula inside individual capsules also protects the retinal from air and light, so potency is preserved right up until the moment it touches your skin.
How do I use it?
Use once daily in the PM, avoiding the eye area. Twist off the capsule tail, smooth the serum over face and neck, and do not rinse. Each carton contains 60 capsules.
Will it irritate my skin?
The formula is encapsulated within our innovative Calcium Buffering System, which is designed to stabilize delivery of Retinal-MD™ and minimize the potential for irritation. In a 7-week U.S. clinical and consumer study, 92% of users agreed it is gentle enough to use every day. If you are new to retinal, start every other night and build to nightly use as your skin adjusts.
How long until I see results?
In a 7-week U.S. clinical and consumer study, 70% noticed less visible fine lines and wrinkles in as little as 21 days, 87% noticed firmer skin in 3 weeks, and 81% noticed an improvement in overall skin appearance. Results build with consistent nightly use.
Can I use it with my other R+F products?
Yes. Intensive Renewing Serum layers easily into an existing routine. For eyes, pair it with Multi-Function Eye Cream. For more firming, add REDEFINE Triple Defense Cream in the AM or REDEFINE Overnight Restorative Cream in the PM. For more hydration, add Active Hydration Serum; for a collagen boost, add Pure C Serum. If you are layering multiple actives, introduce one product at a time so you can monitor how your skin responds.
Is it safe to use during pregnancy or while nursing?
Consult your doctor before using retinal- or retinol-containing products if you are pregnant, nursing, or planning to become pregnant.
What's your money-back guarantee?
We offer a 60-Day Money-Back Promise. If you don't love it, we'll refund the purchase price (excluding shipping) within 60 days of purchase.
