Mandelic Acid 10%, 1 fl oz (30 ml)

I’ve wrestled with ultra-stubborn clogged pores for years—salicylic acid, tretinoin, Differin…nothing budged. But just two weeks into using mandelic acid, they began to clear up, and now they’re virtually gone. It may not be the buzziest acid out there, but honestly, you’d have to pry it from my cold, dead hands.

I've been using this serum for a week and I'm impressed. It's fragrance-free and absorbs quickly without any greasy residue which is perfect for my sensitive skin. I noticed a slight tingling sensation upon the first few applications but it subsided quickly and didn't cause any irritation. My skin tone has become even and some of my dark spots have started to fade. I use it every other night and always apply sunscreen during the day. If you're looking for a gentle yet effective exfoliating serum, this 1 is worth trying.

Got this for my sister because she was looking for something to help with breakouts and uneven skin. She’s been using it for a couple of weeks now and says it’s working well. No irritation or dryness, which is a win since she has sensitive skin. Not really my thing, but if you’re looking for something that works and doesn’t cause problems, this seems solid. She’s happy with it, so I’d say it was a good buy.

I've tried countless exfoliants over the years, but Tree to Tub's Mandelic Acid 10% is truly in a league of its own. As someone with sensitive, acne-prone skin, I’m always nervous about trying chemical exfoliants — but this one has been nothing short of transformative. From the very first week, I noticed smoother texture, fewer clogged pores, and an overall more radiant complexion. It gently exfoliates without the sting or flakiness I’ve experienced with glycolic or lactic acid. Mandelic acid's larger molecule size really makes a difference — you get results without irritation. Another major win? It’s made a huge difference with my post-acne marks. They’re fading faster than ever, and my skin tone looks more even and glowy. Plus, I love that Tree to Tub formulates with clean, skin-loving ingredients that support the skin barrier instead of stripping it. If you're looking for a powerful yet gentle exfoliant, especially for breakout-prone or sensitive skin, this is the one. I’ll definitely be repurchasing — and recommending it to all my skincare-obsessed friends!

Initially I was a bit scared to try this because it is an acid. It is the first time I'll use an acid to exfoliate my face. But it turned out to be very mild. I did not experience any sting and redness in my skin. I have aging skin and it is nice to see that after using this serum, I see that my skin looks brighter. I'm happy with this product!

I'm a bit hesitant to try this in my face because I easily get red spots whenever I try new products on my face--what more an acid! But I've been using Tree To Tub products ever since and I'm absolutely in love with their serums. So I went ahead and tried it. So far, there was no irritation. It was mild and probably because it has hyaluronic acid so definitely moisturizing. Haven't had huge results yet but my skin feels hydrated and my hyperpigmentation appear lighter. Would love to see more!

Gentle and effective! It smooths my skin, brightens my tone and absorbs fast without any stickiness. No redness or irritation, just a nice subtle glow. Been using it for a week and definitely continuing..

Absolutely love this! Super gentle on my sensitive skin but still makes a big difference. My skin feels smoother, looks brighter, and there’s no irritation at all. It absorbs quickly and layers well with the rest of my routine. Definitely a new staple in my nighttime skincare!
