5-STAR REVIEWS

See why customers love PREP cleanser

β€œThis 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.

β€œI 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 beforeβ€”I feel like every other product just sat on top of my skinβ€”and I have never known what it was like to have a product really be absorbed by my skin!” –Catherine M.

β€œI 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.

β€œI 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

PREP cleanser is scientifically proven to enhance the penetration of the OS-01 peptide by up to 2x.01

    Love this!

    I usually have four or five cleansers in rotation, but after using this one, I'm not going to keep doing that. It is able to fully cleanse my skin (even with makeup on, or after an afternoon sweating in the sun) but is gentle enough not to strip it. My skin is noticeably softer and smoother after only a couple weeks of use. Fantastic peoduct!

    doesn't dry my skin

    I've tried other cleansers before and they all seem to dry my skin requiring the use of moisturizers. Yes, we should all use a moisturizer, but why make it dry first? This doesn't do that. My skin feels clean but still soft. Love the way the entire package leaves me feeling. I also love that it has only 3 parts. I'm just a guy. Let's keep it simple.

    Smooth

    A little goes a long way, as it almost melts into the skin and spreads easily. It washes away with little to no effort and doesn’t leave any sort of film on the skin. Seems exfoliating but does not irritate my sensitive skin.
