Time Rewind Retinol Power Serum
Prescription-strength Retinol but formulated for sensitive skin.

"After two weeks my skin is glowing like new. This retinol is unlike any other I've used (and I've tried a bunch). It feels gentle but packs a real punch and my skin is tighter, my pores smaller, and my tone is more uniform and glowing. I can't recommend it enough!"
"I truly love these products. I have noticed a difference in my face from improved texture to less fine lines. I love that the products come in glass containers and reuse pumps."
"It is helping with overall texture and small wrinkles. Nanette Burrows"
"Love all things Exponent!! This is an incredible retinol. Powerful."
"I was hesitant to use the retinol serum initially since I have very sensitive skin and I have tried the pharmaceutical retinoid in the past which horribly irritated my skin. Then I switched to the Exponent retinol serum which produced an extremely mild exfoliation and brightening of my skin. I combine it with Vitamin C serum in the morning. My skin has a healthy glow and the sun spots (from years of sun exposure in the pre sunscreen era) are greatly faded. I have been using this regimen for a few years now and my skin looks much younger than when I started. Using Exponent serums which are always fresh and at 100% potency are the answer."
"I’ve been using Exponent Retinol Time Rewind Serum for 2 months; I switched from another High End Retinol serum from Neiman Marcus. I have seen a substantial difference already. My wrinkles are much softer & my skin feels smoother. It also address my pimples. I’m 71 yrs young and everyone thinks I’m in my early 5o’s."
"With continued use seeing continuous improvements. Gentle on my skin yet remarkably effective. Worth every penny. So glad to discover Exponent Beauty."
"Simply a level above any other product. I hand carry it to London—that's how much I care about using this over competitors."
"I have been using the exponent serums for about 4 months ever since I met Liz at Credo beauty in Plano! I take really good care of my skin and use only clean products. The CoQ10 is amazing and the retinol powder serum is the first Retinol I have ever used that does not try out my skin. This weekend, I plan to buy the vitamin serum to fully round out my quest for firm younger, looking skin. I’m definitely in my beauty era right now and I’m so glad that I met Liz and was able to start on my Exponent journey. These are really incredible products."
"I love this product. I was initially dealing with perioral dermatitis from some product in my line-up, and so my derm recommended I stop using the retinol product I had been for years while it went away. This old product is the well-known brand that gives you a custom nightly formula; it's great, but maybe it was the culprit. Around the same time, I walked into a Credo store and happened to meet the founder of Exponent, Liz, who was there to talk about her products and the innovation of mixing the powder with the serum with customers. She was so warm and helpful, and she gave me the tip that it might actually be my chemical sunscreen at fault because retinol should actually help. I bought the Exponent retinol there that day, listened to Liz's advice to switch to mineral sunscreen, and once the perioral dermatitis (little whitehead looking bumps and dryness that wasn't painful like acne) resolved around my mouth and chin, I added in the Exponent retinol serum as she recommended. It all worked like a charm, and my skin has never looked better. Now, I also use the Exponent vitamin C in the day, after switching from a very popular rose oil vitamin C. Very, very happy and thankful for the results. So lucky!"
