Love and Beware
This is a fabulous product but be aware that if you wash you face vigorously and splash ANY oil on your walls it will stain. I love it but hate the spots that I sometimes get. I have tried a little diluted dish soap but it doesn’t really help.

Whoa- I can’t believe this!
I wanted to try this product for a very specific purpose, I have been looking at facial cleansing wipes to use occasionally at bedtime instead of stripping my face by doing a full wash with cleanser and water. I rarely wear makeup, I spend my energy on finding the best skincare products for my skin and sunscreen. So at bedtime usually, I’m just taking off sunscreen and the day’s grime, or if I didn’t go out, the day’s moisturizing products. I tried several brands of moist facial cleansing wipes, and they left behind a greasy film and my face still feels like it needs a full wash. I would never want to skip properly cleansing my skin, and I usually do a full routine while I shower, but it would be nice to be able to occasionally do something quicker and more convenient without sacrificing on quality. I was hoping this product might cleanse well without needing to be rinsed or breaking me out on occasions where I want something quick and convenient, or maybe am travelling and need a basic routine. Wow, this product is not only perfect for that, it actually makes my skin soft and clean, you’d never know I skipped my regular cleansing and just used this Bioderma product with a cotton pad before my nighttime moisturizers/serum. It completely takes off the day’s water resistant facial sunscreen and any sweat or grime and leaves my skin very clean, soft, not dry, and it feels like there is no residue whatsoever. I also don’t break out or get clogged pores, it is just a clean, soft texture. One cotton pad with product is all takes for my entire face to look and feel just as clean as if I had used my regular products (a cleansing balm followed by a foaming cleanser and lots of rinsing with water). I have used this micellar water quite a bit since receiving it, and have not broken out or had clogged pores from “cutting corners” so to speak. And it cleanses very well. I can’t believe how well it cleanses without needing to be rinsed, without irritating my skin, without clogging pores or causing breakouts, and is suitable to use and then put on my serum and nighttime moisturizer. I’ve even used it the next morning to remove the nighttime moisturizers and then put on my SPF. I worried that I was going to cause my skin not to look as good if I didn’t properly wash and rinse with water but this product is so amazing. I have not yet used it to see how well it removes makeup since I rarely wear any, but just for skincare and cleansing without a full wash with regular water, it is so amazing. Not going to sugarcoat it, this is me wanting a convenient routine when I travel but this is also me being lazy on nights when I’m very tired or mornings when I am in a hurry. I consider this one of my few holy grail skincare products. I have picked up a smaller size for travel. I will keep this on hand always. I’m not even looking at moist wipes anymore. (This product is more gentle and leaves no residue as compared to a dermatologist recommended brand of face wipes). I’m most surprised that it cleans my face so thoroughly and that not rinsing does not cause any irritation or breakouts. Just wow. Totally worth the price. I was going to try other brands but this product has been so good there is no need to.

A little goes a long way!
I'm almost 50 years old and have dry and super sensitive skin. I've struggled to find for years a gentle moisturizer, but effective on my fine lines as well. Omg this works! This gives my skin a beautiful non-oily glow, no negative reactions or breakouts, and leaves my skin so incredibly soft with elasticity. Within minutes it dries (or skin soaks it up) wonderfully, it's not sticky. I'm very pleased with this product, I will be purchasing it again, I hope this product remains the same, and stays on the market. I LOVE this product! I also have no need for my expensive moisturizer anymore, that was quite frankly not as nice as this. Keeps my skin moisturized and soft for 24 hours, fully tested this. I do use an eye cream, but only after I've used this over my entire face and neck after washing. Amazing product, no scent, awesome value for the money. Highly recommend!!

Unique Texture, Amazing Results — Now One of My Favorites!
This serum definitely has a texture similar to snail mucin, so it took me a few tries to get used to — but I’m so glad I stuck with it because the results are incredible. Once it absorbs, my skin feels deeply hydrated, smoother, and so much more plump. The rice and ceramide formula really strengthens the skin barrier, and I’ve noticed my complexion looking brighter and healthier overall. It layers beautifully under moisturizer and doesn’t leave any sticky residue once it settles in. If you’re looking for a hydrating, brightening serum and don’t mind a unique texture, this one is absolutely worth it. It grew on me fast and is now a staple in my routine!
