Morning routine
Apply an even layer to clean face as last skincare step. Reapply every two hours of direct sun.


Sunprotex Oil-Control Fluid is BIOSAR's mineral SPF50+ for blemish-prone and oily skin. Titanium Dioxide and Zinc Oxide shield broad-spectrum against UVA and UVB; Niacinamide regulates sebum and supports an even surface tone, while Salicylic Acid keeps pores clearer through the day. Green Tea Extract helps the finish stay matte under heat and humidity. Use it as the last morning skincare step on face after a Serenvit or Acnemed routine; the fluid layers cleanly under makeup. Reapply every two hours outdoors. Tolerance-tested under dermatological supervision. Suitable for adults with oily, combination, or acne-prone skin.
Serious SPF50+ that shuts down shine and stays matte for hours. Mineral Titanium Dioxide and Zinc Oxide reflect UVA and UVB while Niacinamide balances the look of oil and Green Tea and Peppermint refresh. Salicylic and Lactic Acid keep pores feeling clear — a fresh, non-greasy fluid that protects acne-prone skin without a shiny trace.

How the actives work together
Oily skin wants sun defense that clarifies without ever tipping into dryness, and this fluid is built around that balance. Mineral filters Titanium Dioxide and Zinc Oxide carry the protection while Salicylic Acid, Niacinamide and Lactic Acid refine and mattify shine-prone skin, and Green Tea Extract with Peppermint Extract stay to calm and cool so clarity never turns into tightness. Every clarifying active is met by a soothing one, leaving a fresh matte finish that lasts.
Ingredient Research
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.
The Medical Letter on Drugs and Therapeutics (Sunscreens), 2021 — View research →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.

Niacinamide regulates sebum and supports an even surface tone.
In an 8-week split-face trial in melasma, 4% niacinamide cut the MASI pigmentation score by 62% — comparable to hydroquinone but with fewer side effects. Good-to-excellent improvement was seen on 44% of the niacinamide-treated sides.

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.
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.
Niacinamide
Vitamin B3. Strengthens the skin barrier, helps calm visible redness, and supports balanced sebum. Multi-benefit active suitable for most skin types including sensitive.
Salicylic Acid
Beta-hydroxy acid. Oil-soluble exfoliant used inside the pore to help remove sebum and dead keratinocytes. Standard pharmacy active for blemish-prone skin. Pregnancy use: topical Salicylic Acid at low cosmetic concentrations is considered acceptable during pregnancy when applied to limited areas and without occlusion. Consult your doctor for your specific situation.
Camellia Sinensis Leaf Extract
Its polyphenols act as antioxidants, helping shield the skin's appearance from everyday environmental stress.
Lactic Acid
It loosens bonds between surface cells to ease gentle exfoliation while drawing in moisture for a smoother look.
Mentha Piperita (Peppermint) Leaf Extract
It delivers a cooling, refreshing sensorial effect that leaves the skin feeling awakened and clean.
