Undefined Sun Serum SPF 50 (Untinted) — Mineral sunscreen serum with niacinamide, blue-light defense & lightweight, non-greasy fin

R&R Sun Serum SPF 50 PA++++ (Untinted) is a non-nano mineral sunscreen serum that protects against UVA/UVB, blue light, and pollution while hydrating with niacinamide, jojoba, and rosemary.

Everyday sun protection that doubles as a lightweight skin treatment: this improved R&R Sun Serum blends mineral filters with skin-supporting actives to provide broad-spectrum defense and a natural, skin-blurring finish. Silicone-free, fragrance-free, and noncomedogenic, the formula is water-resistant and absorbs quickly, making it easy to layer under makeup or wear alone.

How does R&R Sun Serum protect skin from daily environmental stressors?

The serum uses 100% mineral filters to physically block UVA and UVB rays while also defending against blue light and pollution. Its antioxidant-supporting ingredients help neutralize free radicals generated by sun exposure and urban oxidants.

• Broad-spectrum SPF 50 with PA++++ for superior UVA protection
• Mineral (non-nano) filters that sit on the skin surface
• Blue light defense to reduce HEV-induced oxidative stress
• Formulated to boost antioxidant activity for daily environmental defense

Will this sunscreen feel heavy or clog my pores?

R&R Sun Serum is designed to be breathable and quickly absorbed, leaving a natural, skin-like finish rather than a thick or greasy film. It is noncomedogenic and silicone-free, reducing the risk of pore congestion for most skin types.

• Light serum texture that blends easily into skin
• Silicone-free and noncomedogenic for minimal clogging
• Skin-blurring finish that pairs well with makeup
• Suitable for sensitive or acne-prone complexions when patch-tested

How does the formula support skin health and appearance?

The sunscreen contains niacinamide plus botanical oils to hydrate, soothe, and help even skin tone over time. These ingredients complement sun protection by supporting the skin barrier and encouraging a smoother, more balanced complexion.

• Niacinamide to support barrier function and reduce the look of hyperpigmentation
• Jojoba and rosemary extract for lightweight hydration and calming benefits
• Boosts antioxidant defenses to help maintain skin radiance
• Water-resistant for up to 40 minutes during activity

How should I use the untinted serum in my routine?

Apply the serum as the final step in your morning skincare routine, before makeup. Reapply every two hours when exposed to sunlight, and after swimming or heavy sweating to maintain effective protection.

• Use liberally across face and neck 15 minutes before sun exposure
• Reapply at least every two hours or after 40 minutes of water exposure
• Works well under foundation or alone for a natural finish
• Available in four shade options for flexible coverage needs

Who is this for: R&R Sun Serum Untinted is aimed at people who want robust mineral sun protection without heavy texture—those who need a breathable, noncomedogenic sunscreen that supports the skin barrier and helps reduce early signs of photoaging. It’s a good fit for sensitive, combination, or normal skin types and for anyone who prefers fragrance-free, reef-safe, vegan formulations that layer easily under makeup.
