oneskin OS-01 Eye Peptide Refill Cartridge 20 mL — Fragrance-Free, Vegan Under-Eye Firming Serum

oneskin OS-01 EYE OS-01 Peptide Topical Supplement Refill is a 20 mL cartridge formulated to target under-eye concerns—dark circles, puffiness, and loss of firmness—delivered as a refill for your reusable pump bottle.

Engineered by longevity researchers, this fragrance-free, vegan refill cartridge replenishes the active peptide formula designed specifically for the thin skin around the eyes. The cartridge contains 20 mL (0.67 oz) and is intended for use with OneSkin’s clear reusable bottle and pump; the refill does not include the outer bottle. OS-01 EYE focuses on improving skin texture, supporting collagen maintenance, and helping the eye area look smoother and more rested over consistent use.

How do I use the refill cartridge with my existing OneSkin bottle?

Replacing the cartridge is straightforward: remove the empty cartridge from your OneSkin reusable bottle and insert the new OS-01 EYE refill, secure the pump, and prime if needed. Use one pump per eye after cleansing to evenly distribute the formula around the orbital area.

• Confirm you have the OneSkin clear bottle and pump before purchasing the refill cartridge.
• Apply one pump around each eye—under-eye to eyelid—after cleansing with OneSkin PREP.
• Follow with OS-01 FACE moisturizer for layered longevity care.
• Store the cartridge upright in a cool, dry place between uses.

What benefits can I expect from regular use of OS-01 EYE?

Consistent application supports improvements to skin suppleness and firmness in the eye area and helps reduce visible signs of aging like crepiness and uneven texture. Lab studies on human skin samples indicate the formula helps support collagen production and retention, contributing to a smoother appearance over time.

• Targets texture and firmness for a more supple feel.
• Formulated to support collagen production and retention.
• Fragrance-free and clean formulation suitable for sensitive skin.
• Designed to complement overall face topical supplements for best results.

Is this safe for sensitive skin and suitable for all genders?

Yes—OS-01 EYE is formulated to be safe for diverse skin types, including sensitive skin, and is free from fragrance. The product is vegan, cruelty-free, and developed under scientific standards to reduce irritation risk while delivering actives to the eye area.

• Fragrance-free to minimize irritation potential.
• Vegan and cruelty-free formulation.
• Appropriate for all genders and most skin types.
• Patch-test recommended for very reactive skin before full use.

How often should I apply it and what products pair well with OS-01 EYE?

Use OS-01 EYE once daily or as directed—apply a single pump per eye after cleansing. For an optimized routine, apply after OneSkin PREP and follow with OS-01 FACE Topical Supplement Moisturizer to layer active longevity support for the whole face.

• Apply after cleansing with OneSkin PREP.
• One pump per eye is the recommended dose.
• Follow with OS-01 FACE for enhanced, full-face benefits.
