Meet PREP, OneSkin's daily facial cleanser designed to lift impurities, light makeup, and sunscreen while honoring your skin's natural barrier. Safe for sensitive skin and dermatologist-tested across skin types, PREP provides a clean start to your skincare ritual. The fragrance-free, vegan formula is gentle enough for daily use and works well as the first step in a broader OneSkin routine.

How PREP fits into your skincare routine

  • Gentle foundation for OS-01 care: PREP prepares the surface so OS-01 can be applied smoothly after cleansing.
  • Supports skin balance: the formula avoids stripping the skin’s natural lipids and helps maintain your microbiome for a balanced feel.
  • Clean and ethical: vegan, cruelty-free, fragrance-free, with no detergents or sulfates that tend to irritate the skin.
  • Safe for all skin types: designed to be gentle enough for a wide range of needs and routines.

Sensory experience and practical use

The gel cleanser feels light on the skin and rinses off easily, leaving a fresh, comfortable after-feel without tightness. Because the formula is fragrance-free, you can focus on the clean skin sensation and the routine itself, whether in the morning or at night, even with sunscreen or light makeup in place.

  • Simple steps for daily use: 1–2 pumps, lather in damp hands until a light foam forms, then massage with circular motions on damp skin.
  • Compatibility: pair with OS-01 skincare to create a prepared base for subsequent treatments.

Lab-informed insights you may notice

In controlled lab studies, using PREP before OS-01 FACE may increase peptide penetration by up to 2x, and a key hydration biomarker (AQP3) showed a notable rise in tests. Individual results vary, and findings reflect controlled conditions rather than guaranteed outcomes.

Who should consider PREP

  • Anyone seeking a daily, gentle cleanse that respects the skin barrier.
  • People with sensitive skin or those avoiding fragrance, sulfates, and detergents.
  • Users of the OS-01 skincare line who want a clean base before peptide-focused steps.

Quality and ethics

PREP is vegan, cruelty-free, fragrance-free, and free from detergents or sulfates that strip skin. The product is designed for all skin types and genders, offering a straightforward cleansing option that fits diverse routines.
