oneskin OS-01 Face Mineral Sunscreen SPF 30 — Untinted 40mL, fragrance-free daily zinc oxide with peptide & antioxidants

oneskin OS-01 Face SPF 30 is a daily mineral sunscreen that pairs zinc oxide broad-spectrum protection with the brand’s OS-01 peptide and antioxidants to shield skin from UV damage while supporting a more youthful appearance over time.

Designed as a lightweight, fragrance-free facial sunscreen, OS-01 FACE SPF 30 uses non-nano zinc oxide for UVA and UVB defense and is blended with the signature OS-01 peptide to address visible signs of cellular aging. The formula includes vitamin C, green tea, and açai extract for antioxidant support and comes in five skin-tone-friendly options (Untinted, Light, Light/Medium, Medium/Deep, Deep) using iron oxides for subtle, blendable coverage. It’s intended for everyday protection — not water resistant — and suits sensitive skin routines.

How does this sunscreen protect my skin from daily sun exposure?

OS-01 FACE SPF 30 relies on mineral (physical) protection: zinc oxide sits on the skin’s surface to reflect and scatter UVA and UVB rays. It’s formulated to be broad spectrum, helping to reduce immediate sunburn risk while contributing to long-term photoprotection when used consistently with other sun-safe behaviors.

• SPF 30 broad-spectrum zinc oxide shields against UVB and UVA rays.
• Non-nano mineral filters suitable for sensitive skin types.
• Designed for daily, leave-on wear under makeup or alone.
• Fragrance-free formulation minimizes irritation potential.

What does the OS-01 peptide do in a sunscreen?

The OS-01 peptide is an active ingredient developed to target visible signs of cellular aging when applied over time. Within this sunscreen, the peptide is combined with mineral protection so daily sun defense also supports skin appearance and resilience rather than only blocking rays.

• Formulated to help reduce visible markers of cellular aging with repeated use.
• Delivered in a leave-on mineral sunscreen for daily application convenience.
• Works alongside antioxidants to protect skin from oxidative stress.

Will the tinted shades match my skin and avoid a white cast?

oneskin offers five shade choices, including an Untinted option and four tinted ranges that incorporate iron oxides for color and light protection. Tints are designed to blend and minimize the typical white cast associated with zinc sunscreens, giving a more natural finish while providing mineral protection.

• Five shade options: Untinted, Light, Light/Medium, Medium/Deep, Deep.
• Iron oxides add subtle color and help with blendability on diverse tones.
• Untinted version available for those preferring no added pigment.

How does this sunscreen support skin beyond UV blocking?

In addition to mineral UV defense, OS-01 FACE SPF 30 includes antioxidant ingredients — vitamin C, green tea, and açai extract — and the OS-01 peptide to help combat environmental stressors that contribute to visible aging. These complementary actives aim to protect and support skin appearance when the product is used as part of a daily routine.

• Vitamin C provides antioxidant support to neutralize free radicals.
• Green tea and açai add botanical antioxidants for environmental defense.
• Combined with the peptide, the formula targets visible aging signs over time.

Who is this for? oneskin OS-01 Face SPF 30 is aimed at anyone seeking a daily, fragrance-free mineral sunscreen that does more than block UV rays: it offers broad-spectrum zinc oxide protection with antioxidant support and a peptide designed to address visible aging. It’s suitable for sensitive skin, those who prefer mineral filters over chemical ones, and people who want a tinted option to minimize white cast and provide light coverage under makeup. Note that the product is not water resistant and should be reapplied as recommended during sun exposure.
