Is this good for all skin types?

Yes! Our Corrective Peptide Serum is formulated for all skin types—even those with sensitive skin. If your skin tends to be reactive to new products, we always recommend a quick patch test.

What is the consistency like?

Our Corrective Peptide Serum is water-based with a slightly thicker, cloudier texture than our other serums—perfect for delivering deep hydration without feeling heavy!

What did the clinical study actually show?

We commissioned an independent 8-week clinical study at Essex Testing Clinic (33 participants). Here is everything it showed: 100% saw reduction in fine lines & wrinkles 100% saw firmer skin 97% saw results in just 4 weeks −25% fine lines & wrinkles (8 wks) +72% firmness & elasticity (8 wks) −16% fine lines (by week 4) +51% firmness (by week 4)

How often should I use this for best results?

Consistency is key! For best results, we recommend using it daily (or nightly) as part of your skincare routine.

Can I use this both day and night?

Yes! The Corrective Peptide Serum fits seamlessly into your routine—morning or night. Once a day is all you need for visible results, so choose whichever works best for your routine.

Will this clog my pores?

No, our Corrective Peptide Serum is formulated with non-comedogenic ingredients, meaning the ingredients have been selected to minimize the risk of pore blockage.

How long do I need to wait between application with other products?

Give the Corrective Peptide Serum a couple of minutes to fully absorb before applying other products—your skin will thank you!

Independent 8-week clinical — see all results

Light yet moisturizing, and it smells amazing. I was talked into a $265 serum at my medspa — I still like THIS one better.

Erin T.

My first peptide serum, and I was skeptical — but in a couple of weeks my skin looked noticeably different. Dewy, not oily, with zero irritation on my sensitive skin.

Gabrielle M.

My skin looks visibly plumper, with a dewy finish. I'm 48, already buying my second bottle — highly recommend these peptides.

Nadia F.

Lightweight but seriously hydrating, and it never irritates my skin. I use it every morning and the Vitamin C serum at night — late 40s and I won't stop.

What Is This Witchcraft?

I’m a 40-year-old breast cancer survivor. As such, I’m struggling into year three of induced medical menopause, and all the stories you’ve been told about estrogen loss are true! I’ve always been mistaken for being a lot younger than I am until recently, as wrinkles and dry, crepey skin have taken over. After The Horrors of chemo I didn’t think I’d mind some aging in my appearance too much, having progressed in my looks at least from full Gollum-mode to Professor Trelawney. But, it turns out, I do. I’m very picky about what I put on my skin so I figured I’d give this a try. I was expecting a little more moisture, maybe? I was not prepared for instant change in appearance with the first application! And it just keeps getting better! Little wrinkles are smoothing out, color and texture are improving….
Please don’t ever do away with this formula, Mad Hippie!

Great Product

Replaced my $$$ repair serum!

Very happy with this serum, after using 2 months daily/ nightly. Replaced my other "repair" serum that was over $130. Now I get a whole skin regimine for less than that, and it all lasts a bit longer. Would recommend!

I’ve been using this for several months now, and I’m seeing smaller pores and better texture. Definitely recommend.

Instructions vs research

For me, this is an effective serum that has decreasedthe wrinkles around my eyes and overall improved my skin appearance. In reading the research matrixyl should be applied twice a day. The instructions that came with the product recommended daily use,which I interpreted as once but based on my understanding of the research twice daily is better. Maybe instruction should be updated?
