Really impressed with this serum. It feels lightweight, absorbs quickly, and doesn’t leave any stickiness. After consistent use, I’ve noticed a smoother tone and some of my dark spots starting to fade. It layers well under moisturizer and hasn’t caused any irritation. A great, affordable option for brightening and evening out the skin! Read more

Works well. Good pricing. Good purchase. While I didn’t have much discoloration, I did notice more even toned skin, in combination with a cleansing and toning regiment Read more

Love this brand. Never had an issue with any of their products. Nice and gentle but effective! Great for sensitive skin, really works to bright dark spots and hydrate skin. Love that price tag! Read more

Worked for me! Top photos are before use; bottom photos are after 4 weeks of nightly use. Full disclosure, I also use tretinoin & SPF religiously (and have for years), but this serum was the one new variable I introduced recently, and I noticed an improvement in my melasma and evened skin tone in just a month. Slightly tacky feel gets one star knocked off, but would buy again. Read more

I started this product along with 5 other facial products at the same time, so I knew it would be hard to say which one was more effective. It was only after I ran out of it, did I see that my dark spots were more visible. After restarting it, I noticed again the difference of how. much lighter my dark spots were. The sun damage is most noticeable on my forehead and sometimes even foundations couldn't cover it. With Good Molecules, this is no longer a problem. I use it twice daily, applying it after cleansing my face and using a toner. After this, I proceed with the usual array of other facial products on top. It has been a God send and a surprise given how little it costs. Read more

This didn't work for me after using it for almost 3 months. I saw no change at all and took before/after pictures under the same lamp and light source to be sure the lighting was the same and not skew the color of the skin discoloration. I use SPF 40 before going out in the sun, wear a hat as well. Disappointed for myself but glad if it works for others. Edit: I was contacted by the seller to make things right. Nothing was asked in return, but this shows that Good Molecules is a business where product quality and business integrity matters. I have raised rating by1 star so that others can make a decision for themselves whether this Tranexamic Acid and Niacinamide Serum formula may work for them. Read more

Just buy it. Works in days, literally liquid gold. I have SUPER sensitive and acne prone skin. This alone helped my skin texture, skin discoloration I have acne scars from years ago. This make them vanish within a week. I wish I was kidding. It is kind of moisturizing but that’s not the purpose of this product. I paired mine with ponds non fragrant moisturizer. HIGH RECOMMEND Read more
