5-STAR REVIEWS

See why customers love PREP cleanser

“This is hands down the best face wash for all ages of skin. I bought this for my daughter who is struggling with sensitive skin and hormonal acne (age 21) and found that I love it for myself (age 50). I keep an extra in the shower and now my 19 year old son even uses it!” – Amy C.

“I am obsessed. I have been using prep + face + eye for 3 weeks now and it’s been a game changer for my skin! Nothing really worked for my skin before—I feel like every other product just sat on top of my skin—and I have never known what it was like to have a product really be absorbed by my skin!” –Catherine M.

“I love this facial cleanser! My skin was dry and flaky with my last cleanser, and this one seems to hydrate my skin while also shrinking my pores. My face has a glow to it I’ve never seen before.” –Ann-Mari B.

“I purchased and use the prep because it enhances absorption of the 0S-01 Face supplement. I notice that my skin is softer and much less dry after using these two products.” –Carol M.

The Science Behind PREP

Maximize the effectiveness of your skincare by preparing your skin for optimal absorption. Our scientists measured the presence of the OS-01 peptide in the skin after applying OS-01 FACE and found that pre-cleansing with PREP enhances peptide absorption by up to 2.2 times compared to not pre-cleansing.01

By improving peptide penetration, PREP can help your skin reap greater benefits from the rest of your routine.

  1. Increases peptide penetration by up to 2x 01
  2. Gently exfoliates without drying
  3. Thoroughly cleanses and preserves skin’s natural balance


Shown in lab studies on ex vivo human skin samples by comparing the amount of OS-01 peptide present in the dermis layer before and after treatment with PREP + OS-01 FACE vs OS-01 FACE alone. Data measured in triplicate.

THE BREAKTHROUGH SCIENCE

Designed to make the OS-01 peptide work harder

    Excellent Cleanser

    My face is so clear after using the Prep cleanser for several months now. I truly feel I cannot use any other cleanser. Every now & then I'll get a small breakout, but it goes away very quickly with some extra attention with the cleanser to that area. My husband uses it now too. Which is saying alot for a man who used to just use the body soap on his face in the shower! The refill is so cost effective and I have it on subscription.

    Prep Facial Cleanser - I love it

    What I love… bottom line, my skin feels clean. There’s zero residue, no greasiness, just soft, nothingness if that makes sense. I had no breakouts and that has happened in the T zone with other cleansers. This product says it prepares your skin for following products and although I have no way of knowing if it does that, I can’t say that it’s not doing it either. I choose to believe that it is. I really like this product and will continue to buy it.
