Sunscreen for Dry and Sensitive Skin

Sunprotex for Dry and Sensitive Skin is BIOSAR's mineral SPF50+ for reactive surfaces and barrier-compromised routines. Titanium Dioxide and Zinc Oxide shield broad-spectrum against UVA and UVB without the chemical filters that often trigger sensitivity; Hyaluronic Acid, Colloidal Oatmeal, Shea Butter, Panthenol, and Argan Oil rebuild comfort and keep the skin calm through daily UV load. Use it as the last morning skincare step on face and exposed areas. Reapply every two hours outdoors. Tolerance-tested under dermatological supervision. Suitable for adults with rosacea-tendency surfaces, dry skin, or post-procedure sensitivity. Pairs with the Sensimed range.

Why it works

Pure mineral SPF50+ for skin that reacts to everything else. Titanium Dioxide and Zinc Oxide sit on the surface to reflect UVA and UVB gently, while Colloidal Oatmeal, Shea Butter, Argan Oil and Hyaluronic Acid flood dry, sensitive skin with soothing comfort. Serious broad-spectrum protection that calms as it shields.

How this formula works

The sun stays outside while deep comfort settles quietly beneath

Dry and reactive skin needs filters that shelter and actives that replenish in the same breath. The mineral pairing of Titanium Dioxide and Zinc Oxide sits gently over the skin, while Hyaluronic Acid, Colloidal Oatmeal, Shea Butter, Panthenol and Argan Oil work below to hydrate, soften and calm. Protection and deep nourishment layer together, so sensitive skin feels sheltered and cared for through the whole day.

Ingredient Research

Active ingredients backed by published studies

  • 4–5%

    Mineral filters work mainly by absorbing UV

    Optical measurements of titanium dioxide and zinc oxide found they reflect only 4 to 5% of UV; most of their protection comes from absorbing it. Reflection matters more for long UVA and visible light. A laboratory study.

  • to 400 nm

    Attenuates UVB through long-wave UVA in lab tests

    Laboratory tests of microfine zinc oxide showed attenuation across the UV spectrum, including long-wave UVA up to 400 nm. It stayed stable under irradiation and did not degrade an organic filter. A study by the material's maker; lab data.

  • 7 days

    Better hydration and less water loss than the vehicle

    A double-blind, placebo-controlled study in adult volunteers: after 7 days, skin treated with dexpanthenol was better hydrated and lost less water than skin treated with the vehicle alone. The abstract reports no effect sizes.

What's inside — and what's not

  • 01

    Titanium Dioxide

    Titanium Dioxide (micronized grades labeled Titanium Dioxide [nano] per EU 1223/2009 Art. 19)

    Mineral UV filter that sits on the skin's surface and physically reflects and scatters UVA and UVB light. Photostable and non-irritating, it delivers broad-spectrum protection gentle enough for sensitive and children's skin.

  • 02

    Zinc Oxide

    Zinc Oxide (micronized grades labeled Zinc Oxide [nano] per EU 1223/2009 Art. 19)

    Mineral UV filter and skin-protectant oxide. It reflects UVA and UVB across a broad spectrum and forms a calming, protective layer — the reason it works both in sunscreens and in soothing diaper-area care.

  • 03

    Hyaluronic Acid

    Sodium Hyaluronate

    Humectant that binds many times its weight in water — one of the most effective hydrators available for topical use. BIOSAR formulates it as 8D Hyaluronic Acid: eight molecular weights working together, from higher weights that hold water and plump the surface to lower weights that carry hydration into the deeper stratum corneum, so one layer hydrates at several depths at once.

    Colloidal Oatmeal

    Avena Sativa (Oat) Kernel Flour

    Finely-ground oat. Soothes the appearance of irritation and supports the skin barrier. Common in dry and sensitive formulas.

    Shea Butter

    Butyrospermum Parkii (Shea) Butter

    Rich plant butter with emollient fatty acids. Delivers lasting comfort on body, hands, feet, lips, and baby skin.

  • 06

    Panthenol

    Panthenol (Provitamin B5)

    Provitamin B5 that supports the skin's repair and hydration signals. Widely used in sensitive, post-procedure, and daily-care formulas.

    Argan Oil

    Argania Spinosa Kernel Oil

    Its fatty acids reinforce the lipid layer to reduce moisture loss and leave skin and hair softer.
