What Is Included

Your complete fresh-mix retinol routine, in one system

Dermatologists often call retinol the gold standard for visible anti-aging. Exponent keeps it fresh until use, then pairs it with hyaluronic acid so each dose is potent, hydrating, and easy to repeat.

You get the protected retinol powder, the hyaluronic acid activator, and a simple evening routine designed to help you stay consistent without using a pre-bottled retinol.

“Retinol remains the gold standard for anti-aging… Exponent’s is equivalent to a starting Rx and the activated powder keeps it potent without the irritating stabilizers typical in liquid formulas.”

I'd tried retinol three times and every single time my skin purged and peeled. I gave up. A friend sent me this. I'm now 10 weeks in with zero irritation and my skin looks better than it did at 35.

My derm told me my skin was too reactive for retinol. I've been using this for 6 weeks. My fine lines are noticeably softer and my skin hasn't had a single red day. I wish I'd found this years ago.

Questions Before You Start

What retinol users ask before trying again

The most important concerns are irritation, strength, mixing, and whether this can fit into a real evening routine.

Is this made for people who usually react to retinol?

It was made for that concern. Time Rewind is for people who want retinol-level results but have struggled with dryness, redness, peeling, or purging from other formulas. Exponent keeps retinol in powder form until use, then activates it with hyaluronic acid. The product page states it was clinically shown to reduce fine lines, wrinkles, and texture in 1-2 weeks without irritation when used nightly on sensitive skin.

Is 0.25% retinol strong enough?

It can be. The point is not just the percentage on the label, it is the potency at the moment you apply it. Time Rewind uses 0.25% pure retinol in powder form so the active stays protected until it is mixed fresh with the hyaluronic acid hydrator.

Is the mixing step complicated?

No. Stamp the retinol powder into your palm, pump the hyaluronic acid hydrator, mix, and apply. Customers repeatedly call the system easy to use, and the page shows it as a simple evening routine.

What if my skin does not love it?

Exponent offers free returns, and the current site also promotes Try Before You Buy. That makes the first order lower risk while you see whether fresh-activated retinol fits your skin.

From Our Customers

★★★★★

"I have been using this regimen for a few years now and my skin looks much younger."

Maria G
★★★★★

"I have been using the Exponent serums for about 4 months. The retinol powder serum is the first retinol I have ever used that does not dry out my skin."

Lisa J.
★★★★★

"I have been using Exponent's Time Rewind Retinol for several months and have had fantastic results. I feel I am getting the full capabilities of the retinol as it is fresh and has not been oxygenated over time, weakening its properties."

Faith C.
★★★★★

"I tried prescription retinol but it was too harsh for my skin. This product is the ideal concentration — it helped even out my skin tone and diminish fine lines without any irritation."

Maria G.
★★★★★

"I have dry, sensitive skin and have shied away from retinol products. The Time Rewind Retinol Pro System has left my skin feeling moisturized and fresh and minimized redness. I love it."

Louise N.
★★★★★

"My derm told me my skin was too reactive for retinol. 6 weeks in, not a single red day. I wish I'd found this years ago."

Jennifer K.
★★★★★

"I decided to once again find a retinol product to help my skin look its best and I found Exponent Beauty to have an easy and effective system. I have also added CoQ10 to my skincare regimen to help my skin look its best."

Lindsay L.
★★★★★

"I've been using the product for almost a year and I am sooooo pleased. I'm 74 and appreciate that I can control the strength of the products. My skin has very few wrinkles and reflects light."

Linda B.
★★★★★

"I'm very sensitive to retinol and never found one I could use consistently without getting little bumps and texture on my skin. I can use this one every night and see a huge difference, with no side effects"

Erin
★★★★★

"I have been using the retinol for about a month and it has not irritated me at all. The system is easy to use and I love that the retinol is mixed with hyaluronic acid. My skin tone looks brighter and feels soft."

Laura B.
★★★★★

"I think I found my new favorite product in the Time Rewind Retinol System. This serum doesn't dry my skin out like some retinol does and I haven't had any peeling. My skin already looks smoother and healthier after just a few short weeks. I've heard about the 'Exponent Glow' and I can say it's real."

AMBER C.
★★★★★

"I was about to pay $108 for SkinCeuticals. So glad I found this first. Same results, $40 less, try before you buy."
