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.

Proven Benefits
What this product does for your skin

Titanium Dioxide and Zinc Oxide shield broad-spectrum without chemical filters.
Barrier comfort
Hyaluronic Acid, Shea Butter, and Panthenol rebuild comfort and moisture.

How the actives work together
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
- SPF 50
Broad-spectrum mineral filter, 98% of burning UV at SPF 50
Titanium dioxide is a broad-spectrum mineral filter that sits on skin and deflects UV. At SPF 50, sunscreens absorb 98% of the erythema-producing rays behind sunburn and photoaging. Everyday, reliable protection.

Full-spectrum shield, all the way to long-wave UVA
In FDA-method testing, microfine zinc oxide attenuated across the entire UV range, including long-wave UVA I out to 400 nm. It stayed photostable and non-reactive, delivering steady broad-spectrum defense.

Deep hydration you can feel, wrinkles visibly softened
In an 8-week clinical study, topical nano-hyaluronic acid raised skin hydration by up to 96% versus baseline. Wrinkle depth dropped up to 40% and firmness rose up to 55%, so skin looked plumper and smoother.

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.
- 04
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.
- 05
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.
- 07
Argan Oil
Argania Spinosa Kernel Oil
Its fatty acids reinforce the lipid layer to reduce moisture loss and leave skin and hair softer.
