Why customers choose Oseila Beauty

PREP is a gentle daily facial cleanser from oneskin designed to remove impurities, light makeup, and sunscreen while preserving your skin's natural balance. The lightweight gel texture glides across damp skin and rinses clean, leaving a refreshed, comfortable base for the rest of your skincare routine. Safe for sensitive skin and dermatologist-tested for all skin types, PREP offers a clean, fragrance-free option to start and end your day.

What makes PREP different

  • Improve the penetration of OS-01 peptide: Shown in lab studies to increase the peptide penetration by up to 2x when used before OS-01 FACE.
  • More peptide, more benefit: By increasing the penetration of the peptide, you can maximize its benefit. This has been confirmed in lab studies by a 40% increase in key hydration biomarker, AQP3.
  • Maintain skin's natural balance: PREP is designed with gentle ingredients to avoid stripping the skin's natural lipid barrier and to help maintain skin's microbiome.
  • Safe & clean: Suitable for all skin types and genders, PREP is clean, vegan, cruelty-free and fragrance-free. Plus PREP does not contain detergents or sulfates known to strip the skin.

How to use PREP

  • Directions: Incorporate PREP gentle gel cleanser into your skincare routine by lathering 1-2 pumps of cleanser in damp hands until a light foam is formed. Then, using circular movements, gently massage onto damp skin. Rinse thoroughly and pat dry any wet skin.

Why pair PREP with OS-01 FACE

Using PREP before OS-01 FACE can help prepare your skin for peptide delivery, based on lab findings, potentially supporting a smoother surface for subsequent actives and a refreshed feel after cleansing.

Packaging and benefits

The PREP cleanser is offered in a refill pouch, making it easy to refresh your routine while keeping the experience lightweight and convenient. The formula remains vegan, fragrance-free, and cruelty-free, with a focus on gentle cleansing that respects the skin’s moisture.
