A foaming cleanser that doesn't dry out my skin!
Style: Tolerance Daily Foaming Facial Cleanser
I have very dry, reactive skin and initially looked past this face wash because it is foaming which is usually a no-go for my skin. I am pleasantly surprised with how well my skin tolerated this product. No dryness or irritation and my face felt clean. I also love that it is fragrance free because fragrances seem to really irritate my skin and who needs to smell their face wash? I am happy to say this is another great product from Avene!

Gentle cleanser for dry and sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser, Style: Tolerance Daily Foaming Facial Cleanser
I have dry and sensitive skin, and this cleanser has worked very well for me. It is very gentle on the skin and has not caused any irritation.
The texture is light and foamy, it spreads easily across the face and rinses off without leaving any residue. After using it, my skin feels clean, soft, and comfortable, without any tightness.
The size is quite large, which I find great because it lasts a long time with daily use.
Overall, a simple but very pleasant cleanser for sensitive skin.

Miracle cream
Size: 13.5 Ounce (Pack of 1)
I have been having crazy acne due to a severe reaction to salicylic acid, among other things. My face was incredibly inflamed, itchy, sensitive, red and painful. My dermatologist started me on an oral antibiotic and a clindamycin/benzoyl peroxide topical. The topical was still drying me out quite a bit so I got this lotion and it's literally a miracle cream. My skin is hydrated, no itchy or stinging and the redness has gone down so much. It's also helping my open sores to heal more quickly. Yes, it's a combination of all 3 products working together but I can definitely see and feel the cream repairing my skin barrier. I will be starting on accutane after a month of antibiotics and will continue to use this balm to keep me from drying up like a prune.
