DERM APPROVED!
I am obsessed with this product!! This feels very luxurious on my skin and does not pill like other products I have had in the past. I have noticed a significant improvement in the background redness in my skin. As someone who works in derm and values good ingredients and products that actually work... I can confidently say that this is the best OTC azelaic acid product I have tried out. It sits very nicely under my moisturizer and does not dehydrate my skin like other azelaic acid products have done in the past. HIGHLY RECOMMEND

A Game Changer for Sensitive Skin
I use this serum every single day, and it has become one of the most important products in my skincare routine. I have very sensitive skin and cannot tolerate stronger active ingredients such as retinol or high-strength acids, so finding something effective but gentle has been incredibly important. This serum has helped calm redness, reduce inflammation, and noticeably improve my skin’s overall appearance and comfort. After dealing with a prolonged inflammatory skin condition, this product made a significant difference and helped restore my skin barrier. The formula feels soothing, hydrating, and non-irritating. If you have sensitive or reactive skin and are looking for a gentle product to help with redness and uneven texture, I highly recommend giving this serum a try. Photos attached: The green bottle is the product and the second photo includes my favorite additions.

Perfect for Acne-Prone Skin!
This serum has honestly been a great addition to my routine for redness and post-acne marks. The texture is lightweight, hydrating, and doesn’t feel sticky or heavy on my oily/acne-prone skin. I have sensitive skin with a focus on barrier protection, and this didn’t irritate my skin at all. It layers beautifully with the rest of my skincare and leaves my skin looking calmer and smoother over time. AND, it doesn’t have a smell!! Definitely one of my favorite azelaic acid serums I’ve tried.

Great product with unexpected results and skincare benefits
Size: 25 Count (Pack of 1)
I have been reading about Micellar water products for a couple of years, and finally purchased these wipes to try. I am currently working very long hours and the selling point for these wipes was that they weren't soap-based, and didn't require a toner after using. I keep them on my night stand and take my makeup off with them prior to going to bed. (I do not use them for removing mascara - I use another product for that.) The biggest point I want to share is that I have been using these wipes exclusively for makeup removal for a little more than two weeks. I have had a stubborn blackhead on my nose for a good 20 years that wouldn't budge, no matter how often I used exfoliating products, and I've invested a lot of money in high end exfoliators in an attempt to make that spot go away. It has grown larger over the years, and was a skincare peeve of mine. I noticed a couple of days ago that that blackhead is beginning to break down and get smaller. I thought at first that I was imagining it, but that blackhead is honestly a good two-thirds gone. This is just from using these wipes! I would never have predicted that something this simple and quite soft and insubstantial as a disposable face wipe would have such effective results for blackhead breakdown, but they're doing the trick. I have noticed smaller blackheads on my chin area are also melting away. I predict that in another few weeks of use, my skin is going to be as close to blackhead-free as it is humanly possible to achieve. (For the record, I don't have a lot of blackheads - just a handful that have taken up residence over the years and refused to budge, getting larger with age.) These are safe for my sensitive skin, and have exfoliating benefits that I wouldn't ever have expected or predicted. Full disclosure: I do spend a good 3-5 minutes using a single wipe on my face, neck, and décolletage, scrubbing with the nubby side (there is a nubby, exfoliating side, and smooth side to each wipe) and using the whole cloth in sections until I have used it all. Finally, I also use it on the tops of my hands. I definitely get my money's worth out of each wipe! I wholeheartedly encourage people to try this product. I now have it on Auto-Ship status, as I don't want to ever be without these wipes in my skincare arsenal.

Cool and moist
Size: 1 Count (Pack of 2)
I had to get away from scented products and this one was cleared by my ACDS app. It is small, not resealable, but easy to use, and cleans well, the wipes are sturdy, and just wet enough to clean without needing extra drying. These are travel size and have to be kept in a zip lock after opening.
