    • 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

    • 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

    • Gentle exfoliation that actually works .
Size: 1 Fl Oz (Pack of 1)
Review Image by Elsi Vazquez Del Toro
I started using this product looking for a gentle exfoliator, and I really like it. It’s mild on the skin, didn’t cause irritation, and leaves my skin feeling smoother after just a few uses. I like that it doesn’t dry out my skin, and the next day my face looks brighter and more even. I’ve been using it at night and noticed an overall improvement in texture. Great option if you’re new to acids and want something not too strong. I have sensitive skin and this worked well for me. I would repurchase. ... 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

    • Smooth, Glowy, and Worth Every Drop ✨💧
Size: 1 Fl Oz (Pack of 1)
Review Image by Ebony
This serum is incredible. It gives my skin such a healthy glow and smooth texture without any irritation. I’ve been using it a few times a week, and I can already see a huge difference — my skin feels softer, looks brighter, and has that natural, dewy finish that I love. The lactic acid gently exfoliates while the hyaluronic acid keeps everything hydrated, so my skin never feels dry or tight afterward. It’s lightweight, absorbs quickly, and layers perfectly under moisturizer or makeup. I love waking up to that soft, refreshed feeling in the morning. It’s the perfect product for when my skin looks dull or tired. This little bottle makes me feel like I just had a facial. If you want radiant, smooth, and even-toned skin without harsh ingredients, this is definitely a must-have. 💕 ... 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
