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!! ### ⭐⭐⭐⭐⭐ Love La Roche posay *by on Reviewed in the United Kingdom 29 May 2026* I love this serum. Expensive do I only buy when on offer. Unsure if corrects hyperpigmentation completely. But my skin feels and looks lush when using ### ⭐⭐⭐⭐⭐ The real deal affordable dark spot treatment *by on Reviewed in the United Kingdom 27 November 2025* 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. ## Frequently Bought Together - La Roche-Posay Mela B3 Serum, Dark Spot Corrector With Anti-Aging Melasyl + 10% Niacinamide, Discoloration Correcting Serum for Sun Spots, Age Spots & Post-Acne Marks - La Roche-Posay Glycolic Acid Serum with Kojic Acid and Vitamin B5, Reduces Dark Spots and Discoloration, Skin Tone Corrector to Brighten and Even Skin Tone - La Roche-Posay Pure Retinol Face Serum with Vitamin B3, Anti Aging Face Serum for Lines, Wrinkles & Premature Sun Damage to Resurface & Hydrate, Suitable for Sensitive Skin, 1.0 Fl.
