WHY WE LOVE IT

Smooth, soften, and renew your skin with the Nine Less 5% Lactic Acid Serum.

This gentle resurfacing treatment uses 5% lactic acid (one of the mildest AHAs) to exfoliate dead skin cells, refine uneven texture, and restore luminosity without irritation. Its hydrating texture helps maintain moisture while it works, leaving skin baby-soft, brighter, and more even day by day. The addition of peptides helps to maintain skin elasticity 

Formulated for daily or frequent use, this serum helps improve dullness, rough patches, and early signs of congestion while supporting a healthier, smoother skin barrier. With continued use, skin looks more refined and feels super soft with a fresh, natural glow.

This is Level 2: Gentle Exfoliation according to Nine Less's rating system. Can be used daily but start out every second day or less if you have sensitive skin.

30ml

What it does: Gently exfoliates, smooths uneven texture, boosts radiance, and hydrates while supporting the skin barrier.

Who it’s for: Perfect for dull, textured, or dry skin, beginners to chemical exfoliation, and anyone looking for a mild yet effective AHA serum that delivers renewed smoothness with zero harshness.

Replaced 3 products
This is a very good product. Everyday I use CeraVe lightweight 30 or 50 spf and mix Drunk Elephant D-Bronzi and B-Goldi drops for a tint and shimmer. This is the only “makeup” I wear as I don’t like heavy makeup and prefer just a subtle glow with a daily sunscreen. This product effectively replaces all of those products for me. I put this on to try yesterday afternoon and my husband immediately said “Did you do something different? You look good.” It’s is a little more runny than I expected but applies thinly (as I prefer) and provides just enough tint to cover some of my redness. The glow is beautiful. Love the packaging, the pump is very easy to manage and keep clean. Too soon to know if it will cause breakouts or how well it holds up in the sun (although my other experiences with SunBum have been that it works well). I will update my review if I have breakouts. Buy this! Edited to add: a dermatologist complimented my skin due to this product “your skin looks great, you’re glowing!” I have not had breakouts from using this product. I still use everyday with a little cream blush and mascara and call it good. I stock up when this goes on sale but even when not on sale it is a great price. Still not 100% sure about it’s effectiveness at sun protection although I’m pretty sure it’s better than nothing. Wish this exact product was available in 50 spf. Still a fave!

A tinted sunscreen.
It was really nice. However, it has a strong tint to it and feels like Makeup with sunscreen. Nice, but uninexpected.

Love!
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.
