oneskin FACE OS-01 Peptide Topical Supplement Refill 50 mL — Fragrance-Free Daily Moisturizer for Sensitive Skin

OneSkin FACE OS-01 refill is a 50 mL topical peptide supplement designed to be used as a daily moisturizer to support skin longevity and help improve the visible signs of aging.

This refill cartridge contains the same OS-01 peptide formula developed by OneSkin to address mechanisms associated with skin aging. It is intended for people who already own OneSkin's reusable white bottle and pump; the cartridge alone replaces the product reservoir so you can continue your routine with less packaging waste. The formulation is fragrance-free, vegan, cruelty-free, and made to be gentle on sensitive skin while fitting into morning and evening regimens.

How does the OS-01 peptide formula work in a daily moisturizer?

The OS-01 peptide is a proprietary ingredient designed to act at biological pathways linked to age-related skin changes. As part of a leave-on moisturizer, it helps condition skin surface attributes—such as texture and radiance—by supporting the product's intended mechanisms. Results reported in clinical testing reflect improvements in multiple appearance measures over a 12-week period.

• Contains OS-01 peptide clinically evaluated across 12 weeks
• Formulated as a lightweight daily moisturizer for face, neck, décolletage, and hands
• Fragrance-free and suitable for sensitive skin to minimize irritation
• Vegan and cruelty-free manufacturing standards

What should I know about using the refill cartridge?

This listing is for the refill cartridge only and does not include the white reusable bottle or pump. Make sure you have the original reusable packaging components before ordering the cartridge so it snaps into your existing dispenser. Use one to two pumps morning and night after cleansing for routine application.

• Refill replaces internal reservoir; compatible with OneSkin reusable bottle
• Apply 1–2 pumps to face, neck, décolletage, and hands twice daily
• Best paired with a gentle cleanser like OneSkin PREP to enhance absorption
• Reduced packaging waste compared with full replacement bottles

What improvements did the clinical study observe?

In a controlled 12-week study, participants reported measurable improvements in multiple aspects of skin appearance. High percentages of users noted enhanced skin evenness, radiance, pore appearance, and firmness, along with reduced appearance of fine lines and wrinkles. Individual results vary, and outcomes depend on consistent use and baseline skin condition.

• Reported improvements in skin evenness and radiance in the majority of participants
• Reduction in visible fine lines and wrinkles reported by most users
• Improved pore appearance and perceived firmness for many participants
• Results documented after regular twice-daily application for 12 weeks

Who is this refill best suited for? This product is intended for anyone who already owns OneSkin's reusable white bottle and pump and wants to continue using the OS-01 peptide moisturizer with less single-use packaging. It is formulated for all skin types—including sensitive skin—and for people seeking a scientifically informed topical supplement to include in their daily skincare routine. If you prefer fragrance-free, vegan, and cruelty-free products and want a refill option for a clinically studied peptide moisturizer, this cartridge is designed for you.
