COSRXAlpha-Arbutin 2% Discoloration Serum Anti-pigmentation Serum for Face with Niacinamide and Hyaluronic Acid, Dark Spot Corrector, Skin Correcting for Even Skin Tone, Korean Skincare 20ml

I ordered and received this serum on the 4th March and it is now the 22nd March. I am blown away by the results. I'd had some really red post inflammatory hyperpigmentation for literal months, right in the centre of my left cheek and along my jaw line, which to be honest I had been managing to cover with Lisa Eldridge's pinpoint concealer technique - side note that method is worth looking into if you have the same issue. But I wondered if I could get something to make the marks fade so I didn't have to wear makeup if I didn't want to. I saw this product and love Cosrx, though i thought I'd try it even though the reviews were mixed. My overall skin tone now has hardly any discolouration. You have to really look for it. I'm so pleased. Also it's a large bottle and the top is really easy to open.

Leaves your skin silky smooth and has helped with my pores. Just hoping in time my brown spots will fade. Will continue to use. Make sure you use SPF and a good moisturizer to keep your skin hydrated

Not sure about the results (I also use retinol and vitamin c), but the multiple ingredients are a good combination so that you don't have to get multiple serums. It has Niacinamide, Traxenamic Acid and Alpha Arbutin as the main actives.
