oneskin FACE OS-01 Peptide Moisturizer Refill 50 mL — Fragrance-Free, Sensitive Skin Formula

OneSkin FACE OS-01 Peptide Topical Supplement Refill is a 50 mL fragrance-free refill cartridge delivering the brand’s OS-01 peptide daily moisturizer to support firmer, more even-looking skin.

This refill cartridge contains the peptide-rich concentrate designed to be used with OneSkin’s reusable white bottle and pump (bottle not included). Formulated to be gentle enough for sensitive skin and free from fragrance, the OS-01 topical supplement is presented as a daily moisturizer that targets measurable signs of aging such as texture, firmness, and the appearance of fine lines.

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

The proprietary OS-01 peptide is engineered to be absorbed into the skin as part of a twice-daily moisturizing step. When applied after cleansing, it complements barrier care and can be layered with sunscreen in the morning. Results reported in clinical testing are tied to consistent application over weeks rather than instant effects.

• Apply 1–2 pumps to face, neck, décolletage, and hands morning and night.
• Use after cleansing to optimize peptide absorption; OneSkin recommends its PREP cleanser.
• Layer with sunscreen during the day for photoprotection.
• Refill format replaces cartridge only—keep your white reusable bottle and pump.

What improvements can users expect and when?

In OneSkin’s 12-week clinical evaluation, participants reported improvements across skin evenness, radiance, pore appearance, and firmness. Most measurable changes appear with sustained use over multiple weeks; individual outcomes vary with skin type and routine consistency.

• Visible improvements reported over a 12-week study period.
• 95.5% saw better evenness, radiance, pores, and firmness in the study.
• 87% reported reduced appearance of fine lines and wrinkles.
• Results depend on regular twice-daily application.

Is this refill safe for sensitive or reactive skin?

OS-01 FACE Refill is formulated fragrance-free, vegan, and cruelty-free, intended to meet clean-beauty standards while minimizing common irritants. Because skin sensitivity varies, patch testing new topical products before widespread use is a sensible precaution.

• Fragrance-free formula to reduce irritation risk.
• Clean and vegan formulation with no animal-derived ingredients.
• Suitable for all genders and most skin types, including sensitive skin.
• Perform a small patch test if you have highly reactive skin.

How do I use the refill cartridge and what’s included?

This purchase supplies the refill cartridge with pump mechanism only; the white reusable bottle is not included. Ensure you already own the OneSkin reusable packaging to transfer the cartridge, or plan to purchase the full set instead.

• Refill cartridge contains 50 mL (1.7 oz) of OS-01 topical supplement.
• Does not include the white reusable bottle; compatible with existing OneSkin dispenser.
• Dispense 1–2 pumps per application to targeted areas.
• Store in a cool, dry place and keep the cap on between uses.

Who is this for: This refill is for people seeking a science-driven daily moisturizer focused on skin longevity and visible texture and firmness improvements, especially those who already own OneSkin’s reusable bottle. It’s suitable for individuals wanting a fragrance-free, vegan topical supplement to incorporate into an established AM/PM regimen and who prefer refillable packaging to reduce waste.
