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!!
Review: Excited to see full results! - Great quality serum! I’ve only been using it for a few weeks so I’m still waiting to see the full long-term results, but it applies beautifully and feels great on the skin. Excited to keep using it!

### ⭐⭐⭐⭐⭐ The real deal affordable dark spot treatment
*by A***M on 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.
