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.

Great quality of product
Size: 1.3 Fl Oz (Pack of 1)
This cream has always been my favorite because it has great quality and effectiveness, I bought it two times and before I used to wear it in the summer and it did not make my skin oily. It is lighter, yet moisturizing if you know what I mean.

This is the new formula, with a blue cap
Size: 1.3 Fl Oz (Pack of 1)
This cream has been a great basic moisturizer for use with acne creams (.25% tretinoin, in my case). You may notice some reviewers saying it's fake because of the blue cap and the fact that it just says "soothing," but that's the new packaging. You can see that on the Avene website.
This doesn't have the "luxe" feel of some other brands, but this did the job by keeping my skin moisturized and acne free. When I am in the mood to buy something else, I usually buy something else, but this is the best budget option - definitely better than any of the drugstore brands.
