🧴 A broad-spectrum SPF 37 daily sunscreen from CIRCADIA built for post-treatment protocols — where UV protection, antioxidant depth, and sensitive-skin compatibility all need to land in one product.

What sets it apart from standard SPFs is the dual-pathway antioxidant system: Lipochroman-6 targets both reactive oxygen and reactive nitrogen species simultaneously — a wider defensive range than conventional antioxidant actives. Alongside it, a patented grape stem cell extract (PhytoCellTech Solar Vitis) reinforces antioxidant defense specifically for UV-challenged skin, and a biotech peptide (Preventhilia) supports visible resilience against photoaging signs. The lightweight, non-greasy emulsion wears comfortably across all skin types, making it a practical daily recommendation clients will actually maintain.

✨ For post-peel, laser, or microneedling clients, it fits naturally into a structured home-care close — reinforcing visible recovery while driving targeted retail conversion.

A strong addition to any esthetics practice that takes post-treatment home care seriously.

• Broad-Spectrum UV Protection: Formulated to deliver SPF 37 broad-spectrum protection against both UVA and UVB radiation, helping to shield the skin's appearance from UV-related photoaging and environmental damage when applied as directed.
• Dual-Pathway Antioxidant Defense: Lipochroman-6 (Dimethylmethoxy Chromanol) simultaneously neutralizes reactive oxygen species and reactive nitrogen species — the two primary oxidative pathways triggered by UV exposure and environmental stressors — helping to maintain a more youthful-looking complexion over time.
• Biotech Antioxidant Support from Grape Stem Cells: PhytoCellTech Solar Vitis (Vitis Vinifera Fruit Cell Extract), a patented grape stem cell extract, provides an additional layer of antioxidant defense specifically positioned for UV-challenged skin, complementing the product's chemical antioxidant system.
• Peptide-Supported Photoaging Defense: Preventhilia (Diaminopropionoyl Tripeptide-33), a biotech-derived peptide, is designed to support the skin's visible resilience against photoaging signs associated with UV exposure, reinforcing the protective benefits of the formula.
• Lightweight Daily Hydration: The emulsion base, anchored by Glycerin and a blend of skin-compatible esters, delivers moisture to the skin's surface in a lightweight, non-greasy texture suitable for daily facial wear across all skin types.
• Suitable for Sensitive and Post-Treatment Skin: Formulated without heavy occlusive textures and enriched with soothing components, this sunscreen is appropriate for use on sensitive skin and as part of post-treatment skincare protocols in professional esthetic settings.

Dimethylmethoxy Chromanol - known as Lipochroman-6: A patented synthetic antioxidant engineered to neutralize both reactive oxygen species and reactive nitrogen species — two key drivers of oxidative stress on the skin. Unlike conventional antioxidants that target only one pathway, Lipochroman-6 addresses both simultaneously, helping defend the skin's appearance against environmental aging factors during daily sun exposure.: A patented synthetic antioxidant engineered to neutralize both reactive oxygen species and reactive nitrogen species — two key drivers of oxidative stress on the skin.

1. Dispense an appropriate amount of product for full face, neck, and ear coverage — a generous application is required to achieve the labeled SPF 37 protection level.
2. Apply to the client's face, neck, and ears 15 minutes before anticipated sun exposure.
3. Spread evenly across all exposed areas, ensuring complete coverage without gaps.
4. Advise the client to reapply frequently throughout the day, especially after perspiring, swimming, or towel-drying, to maintain continuous protection.
5. Instruct the client to avoid prolonged sun exposure even when a sunscreen product is in use.

Professional dispensing and post-treatment use

This sunscreen's combination of dual-pathway antioxidant actives (Lipochroman-6 and PhytoCellTech Solar Vitis) and a peptide designed for UV-challenged skin makes it particularly well-suited as a daily-wear SPF recommendation following treatments that increase photosensitivity — such as chemical peels, laser, microdermabrasion, or microneedling. Introducing it as part of a structured post-treatment home-care protocol reinforces the skin's visible recovery and provides an opportunity for targeted retail conversion. Emphasize to clients that reducing the applied quantity significantly lowers the effective protection level — proper coverage is key to achieving the SPF 37 rating.
