    • Budget-friendly and gentle!
Size: 1 Fl Oz (Pack of 1)
I’ve been using The Ordinary Lactic Acid 5% + HA a few nights a week, and it’s made such a difference in my skin’s texture. It gives a light tingle at first but nothing harsh. After a couple nights, my skin looked smoother and more even, especially around dry or dull spots. I love that it’s budget-friendly yet performs like high-end exfoliants. I always follow with moisturizer and SPF the next morning — and my skin has a soft, healthy glow I didn’t have before. 🌸 Honest note: This is a mild AHA, so if you’re new to acids, this is a great starting point. ... show more

    • great value, great product!
Size: 1 Fl Oz (Pack of 1)
i’m actually using this twice a week on my body to fade some scars. it’s a great intensive treatment for this, but it isn’t irritating at all. despite coming in a tiny bottle (because it’s meant to be used on the face), it has lasted me almost 4 months! and the price, it goes without saying, is AMAZING. an awesome value! ... show more

    • Works well for mature, sensitive skin
Size: 1 Fl Oz (Pack of 1)
I have mature skin (in my 60's) and have started experimenting with some of the Ordinary acids. I'm using this gently on the south side of my eye bags where I have discoloration and what I think might be the beginning of milia, noticing spots but they are not raised yet. I've been using this daily for about 3 weeks and the milia spots have given way to cleaner brighter skin and the discoloration of the circles around my bags have faded. I opted for the milder 5% lactic acid as I have sensitive skin, but also that I would be applying it gingerly under my eyes (disclaimer--check with your dermatologist or PCP first!). I have bags and the contouring dark circle underneath gives me enough room to stay aways from the eyelids and more sensitive areas. I also apply with a q-tip to better control any liquid that wants to run. ... show more

    • Didn’t break my skin out 😁
Size: 1 Fl Oz (Pack of 1)
I’ve had the product for about two months now I can’t say what has changed because I don’t see much of change in regards to dark spots and etc. The hydration of the product is not very hydrating, I don’t think it is alone by any means a primary source of hydration. It also has a nice little stick to it after it dries. I should add which very important. It didn’t break my skin out which makes this superb. My skin is sensitive I know this because I’ve tried other serums that have broken my skin out in ways I’ve never seen before as well as sunscreens. I’ll continue to use it, and edit if any changes ... show more

    • Great price - Great product
Size: 1 Fl Oz (Pack of 1)
I am new to using this product.. but so far I love it! Leaves skin nice and smooth. It didn’t dry out my skin too much. So far I have only used 3 times… once every few days at night. Leave on overnight. I will be purchasing more in the future. Great price!

Great product to start. Glycolic acid was too much for my skin, tried this and has worked great with no irritation

    • Feels like nothing but really is something
Size: 1 Fl Oz (Pack of 1)
This stuff has made a difference in the feel (texture) & appearance (more even tone, lighter dark spots) of my face. I have to say I'm a bit surprised because the first time I used it I thought "Wow this stuff is just like water!" It is the consistency of water, not like most serums and it doesn't have much of a smell plus there is no tingling or burning of any kind. So it actually does feel like you're putting water on your face. I evenade a point to save the box because I thought for sure I'd be sending this stuff back. But I used it for about a week and my face definitely felt smoother and softer, then today after another of twice daily use I noticed while looking in the mirror that my skin tone is much more even and my dark spots have faded a bit. I was surprised, this is the only thing I have changed in my skin care routine so this has to be it. I definitely recommend you give it a try, it's definitely a great deal. **UPDATE: I just changed my rating from 4 to 5 stars. I have used this for 2 months now , I just ordered more. It might last longer for some because I do use it before moisturizer both morning and night(the directions do say once a day tho.) I'm not sure if I mentioned in the first part of my review but I literally cannot count the number of AHA peels and serums that I have tried over several years. This one is refered to as a peel but you do not actually have to take it off once applied. So my update is because this is the BEST AHA formula that I have ever used and what's also great about it is that it is also the most AFFORDABLE one it completely transforms the texture of your face making it incredibly smooth. When I bought it I really didn't expect it to be so great at this price point. I can't say how much I highly recommend this!!! ... show more

    • Love the quality of the product but didnt recieve the quantity that was due to me
Size: 1 Fl Oz (Pack of 2)
Even thought this item is very effective for my acne prone skin and literally helped my skin out tremendously I was disappointed because I purchased the 2 pack and only recieved 1 and couldn't find the option to complain about getting 1 instead of 2. I actually love this company and their products I'm just afraid to reorder anything due to them saying they will send out what is paid for. ... show more
