Good Genes is a must day and night
Been using this for years, together with other Sunday Riley skin care. Made my skin so moist.

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!

Essential Product
This product is amazing! I love it and consider it part of my essential skincare routine. I layer it at night over Luna Sleeping Night Oil. My skin has never looked better. I definitely recommend this product.

The best
I've used this product since it debuted, rotating between using it alone or as part of the Dynamic Duo (with Luna face oil). I always come back to it because nothing compares. It sloughs off dead cells and leaves my face radiant, fine lines nearly invisible, and pores smaller. The scent leaves much to be desired, so I use it at night.

Misleading
I can't believe that I spent so much money on a trial sized bottle of anything..It doesn't work as well as many other cheaper serums that I've used..I want my money back.

I’ve tried COUNTLESS products for my skin, including retinol, which ended up being too harsh. This lactic acid serum is a great alternative, and has completely changed the texture of my skin for the better. This and the vitamin c serum are BEST things I’ve ever used and are worth every penny!!!

Breakouts and Drying Skin
I have been using for about two weeks. My face is dry and breaking out. I don’t know if at this point I should just ditch it.

Pump not working
I brought this product and I can’t pump it out! So now I’m opening the cap to use. I’m very disappointed!

Love this stuff.
I'm 64, skin is healthy but aging. My main concerns are wrinkles (not too deep) and sun damage. This lotion makes my skin look so much better - fresh and bright. I use a few different creams, like the CEO Vitamin C cream and Good Genes is one of my favorites. My skin loves it.

WHAT A SCAM
Wow - it stopped pumping so I opened it up to get the last bit out and come to find the product is in this tiny bag and not even in the bottle - what a rip off and very misleading

Amazing product!
I was experiencing dull looking flaky skin. After only a few consistent applications of this product my skin came alive. The flakiness easily melted away with just minor effort with my washcloth. My skin is brighter and subtle. The texture of the product is smooth and creamy. You will not be disappointed.

Great!
I've definitely seen a difference in my skin since starting to use the Good Genes Lactic Acid Treatment. My skin is less rough and flaky and more moisturized. It looks dewy. I will definitely be adding this to my daily skin routine.

Bottle Half Empty
When my Good Genes arrived, I thought my bottle was half empty. Thinking I must be wrong, I started using it. Loved what it did for my skin but the bottle was empty very quickly. Would not want to buy again unless i could be sure I would get a full bottle.

It smells like a dirty washcloth. Sorry.
I just can't get passed the smell. I would have loved to use this everyday. Have you ever picked up and used a washcloth that had a mildew smell? That's exactly what it smells like!

Irritated my skin
[This review was collected as part of a promotion.] Unfortunately, after using this product for a couple days, my skin started getting really red and irritated, and I had to stop using it.
