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.

    Foaming Cleanser

    I like the facial cleanser, it is a bit less foaming than my previous cleanser.

    Love the refill pouch and it's very easy to refill the original container. Thank you!

    Works very effectively without drying the skin. It's the only facial wash I use.
