Great for dry skin and the whole family
Size: 19 Ounce (Pack of 1)
We use this at home for everyone, including the kids, and it works really well. We all have pretty dry skin, and this cream keeps it hydrated for hours. I apply it after showering and it leaves the skin soft without feeling greasy. It has no strong scent, doesn’t irritate, and hasn’t caused any breakouts. I also feel comfortable using it on my kids because it’s gentle and effective. The jar lasts a long time since a little goes a long way. I would definitely buy it again.

Dry Skin Miracle!
Size: 8 Ounce
I have very dry skin, and around my chin and nose, it flakes and turns red, exposing my inner layer of skin due to severe dryness. I could never seem to hydrate it or get rid of the flakiness. I thought it was just my skin at this point, and I could do nothing to solve it. Now, I've never considered using Cerave; I've always heard negative things about it. However, I've never been a makeup person until now, when I want to try to elevate my look (not to mention I'm always in pain from a lack of hydration). The problem is, my skin is so dry that it cracks the makeup, preventing it from setting well on my face.
Another problem is that around my nostrils, the flakiness looks like boogers, nasty. It's incredibly annoying. So I did a little research, and now I'm here. LET ME TELL YOU! This cream is amazing! I love how thick it is, and how a little goes a long way! My face, for the first time in my short life, is not dry! It's not buttery smooth, as in your hand won't glide against my face, but it won't feel the flakiness and roughness of my skin—and that's a game changer! I'm genuinely obsessed with randomly rubbing my face to feel the almost barrier of hydration, especially around my nostrils! I cannot explain the level of amazement I felt when I touched my nostril area to feel practically smooth skin. I felt as if it were a miracle. I've only used it for a week now, keep in mind, and this is how I feel. PLEASE BUY THIS IF YOU'RE LIKE ME! I'M SO HAPPY WITH THIS PURCHASE, AND IT'S WORTH ALL MY MONEY 🙏

Fast results
Style: MULTIBALM, Style: MULTIBALM
This moisturizing stick is incredible. This is by far the best beauty product I have tried. I had a noticeable difference in my skins appearance in just a couple days. Week 2 my skin is brighter, clearer, softer, bouncier, and just looks overall more healthy. I have tried numerous products for day and night time. I have been using the multi balm stick twice a day and am so impressed. I wait a few minutes to apply make up as it needs a bit to soak in but I was happy it does work well under your make up. Also has a light sweet fragrance with no irritation.

Convenient Hydrating Balm for Quick Touch-Ups
Style: MULTIBALM
Really enjoying this balm stick so far. It’s super convenient to toss in a bag and easy to apply throughout the day whenever my skin feels dry or needs a little glow. It glides on smoothly and gives a hydrated, dewy look without feeling heavy.
I especially like using it on dry areas and around fine lines for a quick refresh. The packaging feels nice quality too. Great skincare item for easy on-the-go use.

I don’t often leave reviews, but this exceeded my expectations and I LOVE it!!! I NEEDED it!
Style: MULTIBALM
I don’t review things unless they REALLY “wow” me, rare, lol. My eyes had been watering for about a month from allergies, then last week my eyeballs were literally hurting so badly, which that had never happened to me before. So I got eye drops made with ketotifen (from the Walmart App) and it got rid of the pain in my eyeballs and stopped symptoms immediately, thank goodness. Then, from the constant watering, rubbing, dabbing and wiping my eyes, alll above, below and around my eyes became raw and chapped, burning and painful. I tried everything! Aquaphore, Goldbond, Pili Ani, and a lot of other brand name high quality face washes, moisturizers, masks, creams, oils and nothing was helping and some seemed to make it even worse. I saw this product and after reading the reviews, decided to give this one last shot before going to a Dermatologist. The moment I applied it, I felt INSTANT relief and soothing. I also was surprised to literally feel it tighten the skin! This morning I woke up to use it, day 3, and before I did I noticed my skin was so much better!!!…No longer painful, discolored or swollen & puffy, the skin was still silky soft from applying it last night, and my orbital skin is 97% better!!! The pink/red/purple has gone away, it’s no longer tender/burns to the touch, and you can literally feel it nourishing and tightening your skin. After begging, my husband let me try it on his skin (lol) just to make sure I wasn’t going koo koo. He noticed too! And commented about how soft it is! Yes~Exactly! It makes your skin like SILK! It is a tad oily when you first put it on, but it “settles” quickly into a gentle softness and doubles as a primer before you apply your makeup! It smooths out your pores and makes your skin so smooth. Just this morning was the first time I applied makeup with it and was pleasantly surprised. I have tested it putting it on the top of one hand and nothing on the other, timed an hour and WOWWWWW the difference in undeniable! I personally recommend using it after washing your face before you put anything else on (moisturizer, makeup, etc). As long as you give it 10-15 minutes to let it absorb and settle, you’re good to go with or without makeup! I’m just really glad I found this because that skin is so sensitive and NEEDS this type of care. This product gets a solid 5 stars from me and I’m excited to make it part of my morning and evening routines! : )
