Safety Warning See back of pack Review: The real deal affordable dark spot treatment - If you prioritize something with a cute package and irresistible scent this is not your serum. However if you struggle with dark spots on your skin/melasma this serum is definitely a helper with guaranteed improvements. It’s not a miracle maker but since I started using it 2x day some of my dark spots lit up or reduced size. More importantly - had no other dark spots appearing on my face since!!! It smells and has the texture of a treatment product- it’s not fragrant at all and if applied in excess will create a yellowish paste on the skin. However if well applied and spread on the skin before your moisturizer none of this will happen. I was quite faithful to caudalie’s vinoperfect serum (has an equivalent cost) but this one, in results definitely makes la roche posay in the lead of anti-pigmentation skincare. Review: Great quality and gives you great results - The product lasted me over two months using it twice a day. It did improve the texture of my skin making it look a lot softer! I think it contributed to reducing my pores. It didn't help that much to remove small areas of melasma, but I guess I will need a stronger product for it. I would say it is worth to buy but I also think there's other brands out there you can get for less and gives you the same result. If I can get it with discount I will get if again for sure!! ## Features - MELASYL TECHNOLOGY: Revolutionary multi-patented active intercepts excess melanin early to prevent marks and effectively target hyperpigmentation. - 10% NIACINAMIDE POWER: Vitamin B3 targets dark marks and pigmentation while soothing skin and strengthening the barrier for complete correction. - CLINICAL EFFICACY: Dark spots reduced for 94% of subjects, with proven decrease in overall spot area after twelve weeks of regular use. - ANTI-MARK ACTION: Fades stubborn post-acne marks and inflammatory hyperpigmentation for a more even skin tone with visible results on all skin tones. - LIGHTWEIGHT GEL-SERUM TEXTURE: Sensorial formula absorbs quickly without stickiness. Hypoallergenic and alcohol-free for sensitive skin comfort. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CM4B43DZ | | Benefits | Corrects dark spots, even persistent ones.
