• Enhances the efficacy of OS-1 peptides.
• Dermatologically tested and safe for all skin types.

PREP is a gentle daily facial cleanser designed to effectively remove impurities, light makeup, and sunscreen while preserving your skin’s natural barrier. Formulated with six active ingredients, it exfoliates, cleanses, and conditions your skin for a fresh, healthy glow.

Breu Branco acts as an antioxidant exfoliant, neutralising free radicals and providing anti-inflammatory benefits. Arnica Extract stimulates microcirculation and hydrates irritated skin, while Japanese Honeysuckle Extract delivers natural antioxidant and detoxifying properties. Prickly Pear Extract gently removes dead skin cells and soothes irritation, aided by its flavonoids that help with sunburn recovery. Niacinamide enhances skin texture by promoting healthy protein synthesis, and Sodium Grapeseed Amidopropyl PG-Dimonium Chloride Phosphate offers antioxidant power 50 times stronger than vitamins C or E.

PREP also primes your skin for the next steps in your OS-1 routine. When used with other OneSkin topical products, such as the peptide eye cream, peptide face cream, and daily facial sunscreen (all sold separately), it enhances the effectiveness of OS-01 peptides by 2x.

Dermatologically tested and suitable for all skin types, including acne-prone and combination skin, this cleanser is the perfect first step towards achieving a healthy, radiant complexion.

1. Dispense 1–2 pumps of PREP cleanser into damp hands and work into a soft lather.
2. Smooth over slightly wet skin on the face and neck using gentle circular motions.
3. Rinse well with lukewarm water and pat dry.
4. Continue with the next steps of your skincare routine, morning and evening.

Pro tip: PREP not only lifts away impurities, excess oil, makeup, and sunscreen, but also helps remove dead skin cells to leave skin fresh and receptive—enhancing the absorption of OS-01 FACE (sold separately) by over 2x when paired together.
