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!
