  • Skin Care for Men
Size: 1 Fl Oz (Pack of 1)
So, I'm a male, and never knew that products like this existed. In fact, I wasn't really aware of a daily skin routine for my face until my doctor suggested using sunblock and wearing sunglasses. Anyways, a friend of mine suggested purchasing an item with the ingredients listed on the label, and let me tell you...my skin looks great. I was not expecting my skin to look bright, and lively. It was very light and not greasy at all. It was very effective in reducing my poor size. This items pairs well with a retinol sunblock (highly recommend) in protecting your skin and giving you that youthful glow. I'm going into my 40s, and I wish this was something I knew sooner. Men (and women) definitely need to pick this up. The price was really good too. ... show more

  • The Ordinary Niacinamide 10%
Size: 1 Fl Oz (Pack of 1)
This serum has been a game-changer for my skin! The niacinamide helps reduce redness and evens out my skin tone, while the zinc controls oil and prevents breakouts. It feels lightweight and absorbs quickly without any sticky residue. After using it regularly, my skin looks clearer, smoother, and more balanced. Perfect for anyone wanting a simple but effective addition to their skincare routine! ... show more

  • Best serum I've used!! Great purchase
Size: 1 Fl Oz (Pack of 1)
I’ve gone through multiple bottles of this serum and always come back to it! It's one of those rare products that actually does what it says without overcomplicating anything. The texture is smooth and soaks in quickly. It layers well under moisturizer and makeup, and doesn’t leave any sticky residue. I have sensitive, acne-prone skin and this never causes irritation or breakouts. If anything, it helps keep things calm and under control. I started using it to help with some redness, texture, and oil control, and it made a noticeable difference in about a week or two. My skin felt smoother, looked brighter, and my pores looked more refined. I also appreciate the simple packaging and dropper, which makes it super easy to apply just the right amount. For the price, you really can’t beat it. It’s a solid part of my everyday routine now and I always make sure I have a backup bottle ready. Highly recommend if you’re looking to even out skin tone, smooth texture, or just improve overall skin health. ... show more

  • Skin so smooth, strangers notice!
Size: 1 Fl Oz (Pack of 1)
This serum has become a staple in my daily routine. Within weeks, I noticed a big improvement in my overall skin texture—smoother, clearer, and more even-toned. I consistently get compliments on my skin now, not just from friends and family but even from strangers. It absorbs quickly, doesn’t feel heavy, and layers well under moisturizer or sunscreen. The price point is unbeatable for the results. If you’re looking for an affordable way to boost your skincare routine, this is it. ... show more

  • Good serum but extra sensitive skin had to be introduced to it gradually!
Size: 1 Fl Oz (Pack of 1)
I have combination skin and usually get a lot of tiny pimples/clogged pores around my nose and under my lip. This serum started minimizing them after a few weeks. But if you have extra sensitive skin (like me), you might have to dilute it for the first week or so. The 10% niacinamide is quite a high concentration and it burned my face the first time I used it. But for the first week or so I used it mixed in with my moisturizer, then stopped mixing it but applied it after my other serum. But now I apply this first right after my toner and it no longer irritates my face. I would buy this again because it's good value (I only need one drop for my whole face and neck) and it works! Just be careful and introduce gradually if you have sensitive skin. ... show more

  • The best
Size: 1 Fl Oz (Pack of 1)
Great product which could easily be priced at 100$. I use about 3-4 different Ordinary serum types. Love them all. Works on my old dull soggy aging skin, seriously. I had a terrible flu and dehydration as a result. I've aged within one day, but this brand serums recovered my face, no kidding I use different brand of a moisturizer cream after that. This is probably the only thing I'm the world that is so affordable and insanely effective! ... show more

  • would definitely purchase again
Size: 1 Fl Oz (Pack of 1)
Good purchase overall! I’ve been using it consistently, and it really helps my skin look smoother and more even. It’s lightweight, absorbs quickly, and doesn’t leave any sticky feeling. I also noticed fewer breakouts and my skin feels less oily during the day. It takes a bit of consistency to see real results, but if you stick with it, it works. Great value for the price, especially if you’re looking to improve texture and manage oil. Definitely a solid product to keep in your skincare routine. ... show more

  • Visible results and much more uniform skin
Size: 1 Fl Oz (Pack of 1)
I have been using The Ordinary serum for about three weeks and I am very satisfied with the results. From the first days I noticed less brightness in the T-zone and a softer texture. Acne marks and small imperfections have been reduced little by little, and pores are less visible. It has not caused me irritation or sticky feeling, it absorbs quickly and works very well before the moisturizer. I recommend it 100% if you are looking to improve the texture of the skin and control excess fat. ... show more
