It is supported with purified Tasmanian pepperberry extract, a known anti-irritant. This water-based serum is ideal for dry skin types. This pH of this formula is approximately 3.8. Lactic Acid has a pKa of 3.8 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability. When pKa is close to pH, there is an optimal balance between salt and acidity.

    • Self-Care secret for busy mom!
Size: 1 Fl Oz (Pack of 1)
As a 40-something year old mom juggling kids, work, and everything in between, I don’t have time (or budget!) for complicated skincare routines. I wanted something simple, effective, and affordable—and the Ordinary Lactic Acid Serum has been a lifesaver. ✨ Gentle but Effective Exfoliation My skin can get a little dull and uneven, especially with stress and lack of sleep. This serum gives me that gentle chemical exfoliation I need without harsh scrubbing. After a couple of weeks, my skin looked smoother, brighter, and just healthier. 🌸 Great for Sensitive Skin I was nervous about acids since my skin can be reactive, but this formula is surprisingly gentle. I started every other night and worked up to nightly use. No stinging, no peeling—just a soft glow. 💲 Budget-Friendly & Simple As a mom, I appreciate that it’s affordable and doesn’t come with extra fluff. The packaging is straightforward, but the product delivers. I don’t feel guilty adding it into my routine. ⏱ Easy to Work Into a Routine After cleansing, I put a few drops on, let it sink in, then follow with a moisturizer. Done. It doesn’t take more than 30 seconds, and that’s exactly what I need in the chaos of mom-life. 🌟 Noticeable Results • Softer, smoother skin texture • Less flaky patches around my nose/chin • Makeup goes on more evenly • A subtle “glow” that makes me look more rested than I actually am! 💡 Mom-to-Mom Tip Don’t skip sunscreen in the morning! Any exfoliating serum makes your skin more sensitive to the sun. I learned the hard way. Overall, this serum feels like my little self-care secret. It’s simple, affordable, and it makes me feel a bit more put together—even on days when I’m running on coffee and dry shampoo. ... show more

    • Part of my holy grail
Size: 1 Fl Oz (Pack of 1)
I alternate this and 0.25% tretinoin every other day and it has been the perfect combo for my acne prone, very fair, very sensitive skin. After spending a ton of money trying everything under the sun to get my cystic acne under control this combo has been my holy trail for less than $20 combined. (I get my tret from All Day Chemist for $6 a tube). For PM moisturizer I use a couple drops of jojoba oil mixed with a pea size of Vanicream in the tub, and only Neutrogena 60 SPF sunscreen in the morning before makeup. My skin is so happy with this light routine - I've tried azaleic and glycolic acid from The Ordinary and some other products too but nothing has been as good as this. It feels very nice on the skin and absorbs quickly with no sticky or greasy residue. They also have a 5% solution which I recommend starting with if this is a new addition to your skin care routine. ... show more

    • IT WORKS
Size: 1 Fl Oz (Pack of 1)
Let me start this of by saying I never write reviews. I have been having trouble with my skin on my cheeks and my nose. All of a sudden, I've been breaking out with little red acne for the first time in my life. I tried everything including retinol cream. nothing worked. It just kept getting worse and then I looked up what I could use for this redness and these breakouts and this product was recommended. When I say that I asked for a fast delivery and I tried it the first night the next morning everything was gone. I'm not sponsored. I am just a random person. Who bought this product and saw overnight results. I'm on day four and I actually use it twice a day now and people are complementing my skin and telling me how it is dramatically changed and it looks great. I don't even know what it is, but I'm going to keep using it and I'm going to recommend it. Doesn't remove wrinkles not that I can see. I have a very thin face, but the skin looks like I had a chemical peel. All the redness is gone. I'm using it for the breakouts and the redness and it's a game changer. ... show more

    • It’s a good buy
Size: 1 Fl Oz (Pack of 1)
I don’t use it as how it’s intended to be used, but it does exfoliate. It might burn if you have sensitive skin. Be careful and use Spf

    • Great gentle exfoliator.
Size: 1 Fl Oz (Pack of 1)
I’ve been using this twice a week as a very gentle exfoliator. My skin always feels extra smooth without any major irritation most acids cause. Easy to mix into lotion, and has a nice lightweight consistency.
