The Power Youth Serum and Cream are formulated to work as a complete two-step routine addressing the five pillars of skin aging, so there's no need to layer on additional retinol or peptide products - these are already included in non-irritating forms. If you're partial to a face oil, we recommend applying it as the final step over the top. Always apply an SPF as a final step before your makeup in the morning. As with all of our products, consistency is key for optimal results.

Absolutely! Each is a complete product in its own right and works beautifully on its own. That said, they're designed to layer well together: the Power Youth Serum preps skin with lightweight hydration, and the Power Youth Cream seals it in with richer, longer-lasting nourishment. Used together, they also layer smoothly under SPF - in our consumer trials, 87% of women agreed the Power Youth Serum and Cream layered well with their daily sunscreen.

Both the Power Youth Cream and Power Youth Serum have undergone extensive dermatological testing. The Cream is suitable for all skin tones and skin types. The Serum contains a higher concentration of active ingredients and is generally well tolerated, though if your skin is very reactive we'd suggest patch-testing it first.

Yes. The Power Youth Serum contains a copper-peptide complex (X50 NeoSyno-Col™) that helps skin look firmer and bouncier, and the Power Youth Cream contains Snap 8™, a peptide that helps soften the appearance of expression lines. (Both trade names are pending final trademark clearance.)

No. The Power Youth Cream already contains Retinyl Palmitate and Bakuchiol, both of which help increase skin's cell turnover and boost collagen production for a fresher, plumper appearance - without the irritation, redness or flaking commonly associated with stronger retinols.

Yes. Between the Power Youth Serum and Power Youth Cream, we use several different molecular weights of hyaluronic acid - including an ultra-fine form that penetrates deeply - so hydration works at multiple depths: some sits at the surface to plump instantly, while other forms hydrate for longer-lasting moisture.
