Lather 1-2 pumps of cleanser in damp hands until a light foam is formed. Using circular movements, gently massage onto damp skin. Rinse thoroughly and pat dry. For best results, follow with OS-01 FACE Topical Supplement.
Where: Face and neck.
When: 1-2 times daily, depending on your skin type. Cleansing nightly is recommended for most skin types to remove dirt, oil, makeup, and SPF. Pro tip: Since your skin is still clean from the night before, skipping a morning cleanse will prevent potential dryness.
PREP thoroughly removes impurities, light makeup, and sunscreen without disrupting natural barrier function, so skin is ready to benefit from the rest of your skin health routine.

How does PREP specifically prepare my skin for the OS-01 FACE Topical Supplement?
Dead skin cells, dirt, and ingredients in makeup and sunscreen can create build-up on the skin that prevents products from fully absorbing. PREP gently dissolves this build-up without disrupting your natural lipid barrier so that OS-01 FACE can absorb more readily–ensuring you see maximum results from our OS-01 peptide.

PREP was also tested for human sensitization (RIPT - a clinical study to assess skin irritation) and no adverse effects were found.
PREP was rated 91% and Top Allergan Free by SkinSAFE. SkinSAFE helps people with sensitive skin find best-in-class products with breakthrough AI-powered science and patch testing data in partnership with the Mayo Clinic.
How should I integrate PREP into my current skincare routine?
Use PREP every evening to cleanse your skin, followed immediately by OS-01 FACE. If you have oily skin and prefer to cleanse both morning and night, you can also use PREP to wash your face at the start of each day.
PREP has not been shown to produce adverse reactions when used with other products and can be safely incorporated into your current routine.
Remember, it’s always best to patch test any new skincare product.

For our comprehensive FAQ list click here.By comparing the amount of the OS-01 peptide present in the dermis layer after treatment with OS-01 FACE, our scientists found that the OS-01 peptide absorbs 2.2 times more effectively when skin is pre-cleansed with PREP versus not pre-cleansed at all.
By measuring the activity of a key gene associated with skin hydration (AQP3) before and after treatment in 46-year-old ex vivo skin, our scientists found that using PREP in combination with OS-01 FACE improved AQP3 activity by 40% versus using OS-01 FACE alone.

I really love this body wash. It cleans well without stripping my skin, and actually leaves my skin feeling soft and ready for the OneSkin supplement. I use it from top to bottom twice daily.
Although can't say I've seen noticeable improvements in my skin yet, my face feels clean and fresh when used. I love the there is no extra scent, junk in the product.
As a licensed Esthetician I can say that this is the best cleanser ever.
So far I'm quite happy with the results. A little bit goes a long way... the face prep and cream are a solid one two combo. Will keep using...
Amazing! I hope OneSkin comes out with PREP for the Body!!!
