Great lotion!
Size: 16 Fl Oz (Pack of 1)
My skin stays dry. I wash my hands numerously throughout the day and the outside of my left index finger is almost always dry or the skin splits from dryness. My elbows sometimes are really dry too. I love this lotion and the smell of it. It performs miracles on my dry skin, it's so good. I definitely recommend to those who suffer from dry skin not only year round, but at any time. I will warn you though that the jar is huge, so it's a lot.

HIGHLY RECOMMEND
Size: 16 Fl Oz (Pack of 1)
I’ve tried many lotions & creams for my rough elbows & dry feet. Soon after I applied this cream I was surprised to see how soft my elbows & feet were. I use this cream on my arms, legs, feet & hands, it has improved the condition of my skin dramatically. AWESOME cream!

Saved my skin barrier!!
I rarely write reviews, but this product truly deserves it. I have sensitive, dry skin with mild to moderate rosacea that became even more fragile after chemotherapy. While trying to repair my skin barrier, I overdid it with actives and completely wrecked my skin — it was red, raw, burning, and peeling. I turned to ChatGPT for help, and this Avene Cicalfate+ was one of the top recommendations. I started using it about three weeks ago, and wow — the difference is incredible! My skin has healed beautifully. The redness is dramatically reduced, the irritation is gone, and my skin feels soft, smooth, and calm again. The texture is soft and luxurious without being sticky. I love that there’s no noticeable scent, which is perfect for sensitive skin. It arrived well packaged and intact. For the results it delivers, I consider it an amazing value and will absolutely repurchase again and again. If you’re on the fence about trying this, go for it — it truly rescued and revived my skin barrier. This is now a permanent part of my routine and 100% a holy grail product for me!

Hydrating and Powerful Barrier Repair Serum!💧
This serum has been life-changing in calming and restoring my skin barrier. It absorbs quickly, feels lightweight, and instantly soothes irritation without feeling greasy. I’ve noticed my skin looks healthier and more balanced after just a few uses. It’s gentle enough for sensitive skin and works especially well when my skin barrier feels compromised. It is also fragrance-free, which I always appreciate! Trust me, it’s well worth the money!

Works as created.
Have been using for a few weeks and have noticed 15% improvement in skin and issues. I did notice a difference in the first 24 hours as advertised. It is suggested need a full month I think to see the true results. At 50 I have pre menopausal skin issues- the redness & inflammation, acne, tightness and sensitivity. It is helping in addition to the other Avene skin products that come in the trial box for sensitive or SOS skin box trial size I think ot is called. This has made a difference. It is easy to apply. I use morning and night. It is different from the Cicalfate + Cream. I use that also as needed. I am happy and recommend it. The price is higher than what I spend. But I wanted to try it to see of i need more than just what was in the Avene sensitive skin trial size box they have. My skin is really red and irritated so the $40 for the bottle is was willing to try because it's painful on my face.
