Color Changing Foundation
🇰🇷 Formulated in Korea
Reverse-time Peptide Serum

Try it worry-free. If our serum doesn't work for you, you'll get your money back*
Why is this different?
We name every active and tell you exactly what it does. Argireline and Matrixyl for the look of fine lines. Niacinamide, vitamin C and tranexamic acid for dark spots and dullness. Collagen and hyaluronic acid for instant plump. No "secret complex," no mystery. If a serum won't tell you what's in it, that tells you something too.
What's actually in it?
The short answer: the good stuff, and we'll name it.
Argireline and Matrixyl. Two of the most researched peptides in skincare, working on the look of fine lines and firmness. This is the duo that gives the serum its name.
Vitamin C and Niacinamide. The brightening pair that fades the look of dark spots and brings back the glow.
Collagen and Hyaluronic Acid. The instant part. Skin looks plumper and dewier from the first drop.
No fragrance. No drying alcohol. Nothing hiding behind a "secret complex." The full ingredient list is right below, because we think you should always be able to read it.
Aqua, Glycerin, Butylene Glycol, Niacinamide, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, 1,2-Hexanediol, Squalane, Dipropylene Glycol, Tocopheryl Acetate, Coco-Glucoside, Hydrolyzed Collagen, 3-O-Ethyl Ascorbic Acid, Tranexamic Acid, Sodium DNA, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Arginine, Cetyl Alcohol, Trehalose, Glycine Soja (Soybean) Seed Extract, Polysorbate 60, Sorbitan Isostearate, Opuntia Ficus-Indica Stem Extract, Ethylhexylglycerin, Caprylhydroxamic Acid, Pentylene Glycol, Phenoxyethanol, Polysorbate 20, Tapioca Starch, Acetyl Hexapeptide-8, Hydrolyzed Sodium Hyaluronate, Carnosine, Palmitoyl Pentapeptide-4, Polylysine
How should I use it?
- Start clean — apply morning and evening to cleansed, slightly damp skin.
- 2 to 3 drops — warm between fingertips, press into face AND neck.
- Focus — extra drop patted onto expression lines, crow's feet, dark spots.
- Seal — follow with the Color Changing Foundation for an even better result.
When will I see results?
Faster than you'd think, and it builds. The plump, dewy glow shows up within days. A brighter, more even tone follows over the next few weeks. Then the peptides take over, smoothing the look of fine lines from week four onward. Your skin keeps looking better the longer you use it.
Is it worth the price?
It replaces three serums: a peptide serum, a brightening serum and a hydrating serum. Bought separately, that's easily double the price, and three extra steps every morning and night. One bottle, one step, everything your skin needs.
How does the guarantee work?
Try it for 30 days, risk-free. Use it morning and night, and if your skin hasn't changed, email us within 30 days of delivery for a full refund of your bottle.

“I wasn’t expecting to look 25 again, I just wanted my skin to feel less dry and look a bit fresher. I’ve tried plenty of things over the years, so I didn’t have huge expectations. But I’ve really enjoyed using Reverse-Time. My cheeks feel softer and my skin doesn’t look quite so tired. I still look my age, which is fine by me. Just feeling a bit better about my skin lately.”

“My daughter bought me Reverse-Time for my birthday. She knows I’m always complaining about how dry my skin feels! I’d tried quite a few serums already, so I wasn’t expecting much, but I started using it every evening before my cream. After a while I noticed my cheeks felt softer and my skin looked a bit fresher. Nothing happened overnight, but I’m really pleased with it. Already told my daughter she chose well.”

“I’m terrible for buying a serum, using half of it and then trying something else. This one I’ve actually stuck with. My skin feels soft and comfortable afterward, and I like how it fits with the moisturizer I already use. Nothing complicated. I’m getting near the bottom of the bottle now and will be ordering another, which is probably the best review I can give it.”

“My skincare routine has always been pretty basic, usually just washing my face and putting on some cream. I started using Reverse-Time in the evening and have got into a nice little habit with it. My cheeks don’t feel as dry and I like how soft my skin feels afterward. It’s only a couple of minutes, but I look forward to it. A little something for myself.”

“I nearly didn’t order this because I already had enough skincare sitting in the bathroom. Glad I did though. It wasn’t one of those overnight things, but after using it regularly I started noticing my skin felt softer and looked a little less dull. Even my husband knows which bottle it is now because I mentioned it a few times! It’s earned its spot on the shelf.”

One serum. Three jobs.
A peptide serum for lines. A brightening serum for spots. A hydrating serum for glow. Normally that's three bottles, three steps and three bills.
We put them in one formula. It layers perfectly under moisturizer and makeup, morning and night. Apply, press in, done.
Visibly softens fine lines
Fades dark spots

How does it work?
Right away: collagen, hyaluronic acid and squalane draw in moisture and plump the skin's surface. Dry lines look softer the same day, and skin gets that rested glow back.
Within weeks: niacinamide, stable vitamin C and tranexamic acid work on dark spots, sun damage and dullness. Skin tone looks brighter and more even.
Over time: Argireline and Matrixyl, two peptides with over 20 years of research behind them, smooth the look of expression lines on the forehead and around the eyes.
Stay consistent, morning and night. Your mirror does the rest.

Frequently asked questions
How do I use it?
Apply 2 to 3 drops to cleansed, slightly damp skin, morning and evening. Press into face and neck, then follow with moisturizer. In the morning, always finish with SPF.
When will I see results?
Hydration and glow are immediate: skin looks plumper and dewier from the first uses. Brightening takes longer, expect a more even tone within 2 to 4 weeks. The peptides are the slow burn: the look of fine lines keeps improving over 4 to 8 weeks of consistent use. This is why we give you 30 days to judge it.
Can I use it with my other skincare?
Yes. It plays well with retinol, moisturizers and SPF. Apply the serum first on clean skin, let it absorb for a minute, then layer the rest of your routine on top. If you use a retinol at night, apply the serum first and the retinol after.
Is it okay for sensitive skin?
The formula is fragrance-free and contains no drying alcohol, and the vitamin C is a stable, gentle form chosen to brighten without the sting of pure vitamin C. As with any new skincare, do a small patch test on your inner arm first if your skin reacts easily.
How does the money back guarantee work?
