Eucerin Spotless Brightening Sun Serum SPF50+ 50ml – Patented Thiamidol Sunscreen Clinically Proven 97% See Dark Spots Reduced in 4 Weeks Photostable No Octocrylene Non-Comedogenic Sensitive-Skin Tolerated

✨ Key Benefits ✔️ SPF50+ + Higher-Than-EU UVA + HEVIS Defense (Advanced Spectral Technology):​ Broadband photostable UVA/UVB filters (no Octocrylene in the global MY/SG/TH formula) plus high-energy visible (blue) light​ defense — blocks the UV main driver of new pigment andthe HEVIS secondary driver that darkens melasma.✔️ Thiamidol® Inside (Same Patent as 3D Serum / Body Lotion):​ Inhibits human tyrosinase at the root of melanin production — visibly reduces sun spots, age spots, post-acne marks and melasma over time, and helps prevent reappearance​ when used daily. This is what makes it a "serum" not just a sunscreen.✔️ Licochalcone A + Glycyrrhetinic Acid:​ Licochalcone A (Glycyrrhiza inflata root) neutralizes UV/HEVIS free radicals and calms inflammation; Glycyrrhetinic Acid supports skin's own DNA repair mechanism after UV hit. Together they cut the "sun → redness → pigment" loop.✔️ Serum Texture, Not Creamy Sunscreen:​ Light, fast-absorbing, non-greasy, non-sticky — sits under makeup without pilling, no white cast mentioned in PIU panels (tint-free but blends transparent on most tones). Clinically proven tolerable on sensitive skin.✔️ Replace Your Day Cream Step:​ Designed to be applied after, or instead of, your regular AM day care — one bottle does UV defense + antioxidant + Thiamidol treat at once. Pairs with Spotless Brightening Booster Serum (PM) or 3D Serum (PM) for a treat-at-night / protect-by-day loop.✔️ Clinically Proven (PIU, 160 women 25–55, hot/humid, 4 wks):​ 98% said protects effectively against sun-induced pigmentation, 97% dark spots reduced, 97% more even complexion, 96% absorbs quickly.✔️ Free of Microplastics (UNEP def), FSC carton, no Octocrylene​ — sustainability stack matches Eucerin Sun global commitments.🧴 How to Use When:​ Every morning, regardless of weather/indoor plans (UV/HEVIS penetrates glass).Where:​ Face, neck, décolleté. Ears + back of neck if exposed.Amount:​ Full coverage needs ~a thick line from fingertip to wrist per zone (don't skimp — halving the amount drops protection sharply). Step order:​ After cleanser/toner → this serum (instead of day cream)​ → makeup if needed. No wait-time required, but let it set ~1 min before foundation.Reapply:​ Every 2h in direct sun, after swimming/sweating/toweling. Reapplication counts toward the Thiamidol cap.Thiamidol Daily Cap (critical):​ Across ALL face products with Thiamidol​ — 3D Serum (AM or PM) + this Sun Serum (AM) + Booster Serum (PM) + Body Lotion (if on neck/décolleté) — total ≤ 4 applications/day. Typical safe loop: Sun Serum AM (1) + 3D/Booster PM (1) = 2/day, fine.PM:​ Cleanse off thoroughly (double cleanse if wore all day), follow with non-Thiamidol night care or a Thiamidol serum if cap allows.💡 Ideal For All skin types including sensitive, with sun spots, melasma, post-acne marks, age spots, uneven tone.Anyone already in the Eucerin Spotless Brightening / Anti-Pigment / Thiamidol ecosystem​ who wants the AM protect step to also treat.Users who hate layering day cream + separate serum + sunscreen — this collapses 3 steps into 1.Hot/humid climate users (PIU ran in Thai/MY climate) who need high SPF without heavy feel.Not​ a body sunscreen (face-only 50ml format); not​ a replacement for PM leave-on Thiamidol serum if you want faster spot correction — AM protect + PM treat is the fastest loop.
