oneskin Peptide Lip Mask OS-01 — 7ml Overnight Plumping Treatment, Non-Sticky Hydration

OS-01 Peptide Lip Mask is an overnight, peptide-rich lip treatment that hydrates deeply and helps restore fuller, smoother-looking lips while you sleep.

Designed for the lips — the most exposed and delicate skin on your face — oneskin OS-01 uses a targeted peptide complex to address signs of thinning and surface texture changes over time. The formula feels rich without stickiness, melts into a comfortable overnight layer, and holds moisture through the night. It is fragrance-free, non-comedogenic, dermatologist-tested, cruelty-free, and carries the National Eczema Association Seal of Acceptance.

How does the peptide work to improve lip volume?

The proprietary OS-01 senescence-blocking peptide is formulated to interact with cellular pathways associated with aging. By supporting skin resilience at a cellular level, the peptide helps lips look visibly fuller and reduces the appearance of fine lines with consistent use.

• Targets cellular mechanisms linked to thinning lips.
• Supports smoother surface texture and reduced fine lines.
• Designed for cumulative improvement with nightly application.

Will this feel heavy or sticky on my lips overnight?

No—OS-01 Lip Mask is crafted to be rich yet comfortable. It melts into a smooth layer that locks in hydration without leaving a tacky residue, so it stays in place while you sleep and rinses or absorbs by morning.

• Rich, non-sticky texture that absorbs overnight.
• Leaves lips soft and plumped by morning.
• Applies evenly with the included reusable metal applicator.

Is it safe for sensitive or eczema-prone lips?

Yes—this lip mask is fragrance-free and has earned the National Eczema Association Seal of Acceptance. It is dermatologist-tested and formulated without parabens, sulfates, or phthalates, minimizing common irritants for sensitive skin.

• Fragrance-free formulation reduces irritation risk.
• NAEA Seal and dermatologist testing for added reassurance.
• Free from common irritants like parabens and sulfates.

How should I use the OS-01 Lip Mask for best results?

Apply a generous layer to clean, dry lips using the reusable metal applicator before bed, and leave it on overnight for a deep treatment. Use nightly to build and maintain hydration and visible smoothing effects.

• Use the metal applicator to spread a generous layer.
• Leave on overnight for sustained hydration and treatment.
• Consistent nightly use supports cumulative improvement.

Who is this for: OS-01 Peptide Lip Mask suits anyone wanting a targeted overnight treatment for thinning or aging lips, particularly those seeking a fragrance-free, dermatologist-tested option that is safe for sensitive or eczema-prone skin. It’s ideal for people who prefer a non-invasive, nightly skincare step to hydrate, smooth, and support fuller-looking lips over time.
