I've been using it for a month now, and I feel like the wrinkles around my eyes have thinned a little. The carbonated foam feels moisturizing and spreads easily.
The lotion penetrates deeply! I feel there is a huge difference between having this and not having it. I've bought several bottles and have been using other products and skipping out on using it, but that's when I really noticed it. I noticed a difference in how soft and smooth my skin felt, and since then I always use this right after washing my face. It also smells great.
I've repurchased this product so many times, it's a favorite of mine. The power of carbonation is truly amazing. The way my skin texture improves with or without it is completely different... I'll be using this forever!
I use the entire EST skincare line. I usually buy refills, but since it was a gift set, I bought the full product. This introductory serum is a must. It soaks up tons of lotion!
I've tried a lot of different introductory serums, but this one suits me best, including the feel of the product. Even with my usual skincare routine, I can't prevent my skin from drying out or losing its firmness without this. My skin gets dry if I don't do skincare right away after a bath, but if I use this first, I have time to moisturize my kids and change their clothes, so I feel at ease. I've had my favorite lotions and emulsions for many years, but using this one has really brought my long journey of skincare exploration to a close!
