So good
I noticed results within days of starting use. Smoother complexion, softer skin, more even tone fast. I'm obsessed.

✨ This product has changed my skin for the better ✨
I started using Sunday Riley Good Genes (Lactic Acid) back in 2023 when my melasma had flared up badly, and it honestly became one of the few products that made a noticeable difference. After a few months of consistent use, I saw drastic improvements in the look of my discoloration and overall tone. My skin looked brighter, smoother, and more even, and my texture felt noticeably softer. What I love most is that it delivers real results without feeling harsh or stripping, and it layered well with the rest of my routine. It's one of those "you can actually see it" products, and I keep coming back to it when my skin starts looking dull or uneven again. Pricey, yes, but for me it was worth it because it genuinely helped calm down a stubborn melasma flare and made my skin look healthier overall.

Must have product
I always go back to Good Genes , I have sensitive mature skin that gets dry but also breakouts .. this helps clear the dead skin on a cellular level it's irritated or red it just looks dewy and healthy. I use this for healing deep pimples too to prevent dark spots after they are gone. Combine with a nice C oil and some gel cream I like ceo and dermalogica or comfort care (Davines skin care) I get so many compliments about my skin when I stick to this routine

A holy grail skincare product!
This is one of my holy grail skincare products! It’s absolutely amazing. I only use it once a week and I CAN tell a difference the next morning. My face is tight and firm after using this. It also looks smoother. It does have an odd scent, but it’s easy to get past after seeing the results. I’ve been using it for a few years now and it’s something I always keep in my nighttime skincare routine. It’s a must have for me. I get complimented on my skin often, a lot of the time after I’ve used this. I will always recommend this product!

!!!Skin Beware!!!
I purchased the skin routine kit the first 2 items in the kit were great, but when i got to the 3rd item (lactic acid) I put the product on my forehead and was moving downward and immediately a burning sensation started then where i olaces the product started burning it was unbearable! I immediately splash my face with cold water but the damage was done! My face was terribly burned! It was truly awful! I still have scarring on my forehead!

Absolutely works! Noticeable difference!
Well, I originally got this in my Boxy subscription. It kind of tingled right away and I put it aside and didn't use it for a while. I decided I would try because I have some redness and due to having an olive complexion, if I get a zit it remains a dark spot for months. I started using it a few times a week, at night. I would do my skincare and I would dispense one or two pumps on the top of my left hand. I would dab it on my face and continue to use my left hand as the place I would consistently apply the product from. I thought it was working but then I realized my left hand compared to my right, the texture was gone from my hand, any dark spots were gone from my hand and after a few weeks of using it the results were so noticeable I would show my family and friends. I highly recommend this product to people! it definitely works on your face, skin, hands and my sister is using it for her melasma.

Love
Feels like it gives a glow I have been using it twice a day I would buy it again. I am new to skin care. It is supposed to to exfoliate so I'm trusting it does. I moisturize on top as instructed

The only product I'm willing to spend this amount
This was given to me as a gift and I will definitely be purchasing this myself when I run out because this stuff is amazing! I do have sensitive skin so I only use it every other night and it does wonders for exfoliating and clearing up my skin.

It's my secret staple
I dont believe in gatekeeping but honestly I do a little with this product. Works so well and so quickly, I've tried cheaper options and fiferent brands but this one is one of a kind. Worth the price just wish they spent less money on the packaging so I could get more product.

Amazing Results
I've been using Good Genes for only a few weeks and I already see the difference in texture, brightness, and fading of fine lines and under eye bags! I wish I'd found Sunday Riley products far sooner than I did!

I Would Never Pay Full Price
At 50% off it is an okay Lactic Acid leave-on but there are many other products that do the same thing at a lower price point. This was a 21 days of Beauty Deals purchase and I'm. It sad I tried it.
