Perfect for sensitive skin
Size: 1.3 Fl Oz (Pack of 1)
I have insanely sensitive, blemish prone skin and have been struggling to find skincare products that don’t irritate my skin. This was recommended to me by my dermatology office and I’m obsessed. My skin doesn’t get irritated and I don’t break out. It feels amazing. Not too thick, not too thin. As an added bonus, it smells great.

Great for sensitive skin and moisture protection
Size: 6.7 Fl Oz (Pack of 1), Size: 6.7 Fl Oz (Pack of 1)
I love this brand of products and i initially bought this thinking it was a facial lotion. I was going to return it but I was pleasantly surprised after feeling the texture and then trying it out. My skin was in a drying phase so after using this I could sense a noticeable improvement in my skins softened and hydration. There is no scent and it has a very rich lather so a little goes a long way. The amount is perfect for the price and it is one of the better values.

Best face lotion for combination skin
Size: 1.3 Fl Oz (Pack of 1)
Best face lotion. Leaves my skin feeling hydrated without being oily (I have combination skin). Only downside is no sun protection. But lotions with sunscreen tend to make me break out. Ive used this lotion for about 8 years and its the only one that I dont break out with.

My Holy Grail for really good moisturizing!!
Size: 1.3 Fl Oz (Pack of 1)
Ok this is long but worth it, I hope.
I absolutely LOVE this moisturizer. It is very moisturizing, and doesn't just sit on top of your skin, it soaks in! I messed up my skin barrier with some products because as I hit my 40's it couldn't handle the strong stuff (Retinal, Vit C, AHA/BHA) that I have used daily for 20 yrs. So rude, like hormone changes and wrinkles weren't enough, lol. All of a sudden my super oily skin was still oily, but also had really dry spots. I was at a loss. This moisturizer works so well and helped repair my skin barrier without breaking me out!!
I also use the Avene Thermal Spring Water spray, it also really helped me get my skin back under control and I will never stop using it. The water spray is super light, feels like water, and soaks in so well... truly is very moisturizing while being super light. I apply that first, then my serums and moisturizer.
**Other products I also use: the Avene Cleanance Concentrate I use on my areas where I get blemishes (still getting breakouts in your 40's is also rude)... it helps those areas stay clear but moisturized, doesn't dry my skin at ALL. Also use there Retrinal and A-Oxitive... my skin just was not tolerating my usual stronger Retinal and VitC. These two work really well without the irritation!! Iise them on alternating days for now. I have tried many many brands, skincare is my thing...and I truly love every single product I have used by this brand, really am glad I found this product line!! Hope this helps someone.
