    So far…

    I have been using it for almost a month, no irritation, no redness, spreads great, and absorbs quickly. My skin looks even better for a 55-year-old. I don't have creepy skin… yet… so I'm using it to avoid exactly that or delay it as much as possible. Give it a try, won't regret it.

    Miracle in a bottle!!

    I use this Body Serum from my neck down to the souls of my feet and it moisturizes me unbelievably!! I have a bottle sitting on my bathroom sink as well that I use on my hands every time I wash them. My hands stay soft and moisturized morning to evening. I also use it morning and night on my elbows and they are so soft because of it!!

    Noticeable improvement

    The Body Retinol has been such a great addition to my routine. It absorbs quickly, feels nourishing, and has been gentle on my skin. I've noticed a real improvement in my skin's texture - smoother, more even, and healthier overall. It delivers results without irritation and I love using it every night.

    Test period still!

    I have been using it for 2 weeks, haven't seen any results yet, but the texture is great, no smell, no irritation. I'm just scared that don't last the whole month, you can't see how far the bottle is, so that's my only concern.. 😆
