I learned about KAVI through my son's dermatologist, and their sulfur bar worked so well for his acne, I thought I'd try their anti-aging line for myself.

There's a lot of literature to read through if one is inclined to educate oneself on what exactly is going on in your skin and how KAVI's products make a difference. I've taken it to heart to learn more, and I think I understand better now what I'm doing with these products. It's only been about 6 weeks now, and I haven't seen any dramatic results, but, I love the glycolic cleanser, serums, and the SPF. Everything feels so fresh and pure.

The peel that came with my system (30%), however, is too strong for my skin. The first peel stung like bananas, and I haven't had the guts to try it again. I'm not sure how critical this component is to the whole system, but maybe I'll do it once a month instead of once a week.

Overall, I like these products over what I'd been using before (Clinique, Murad, Perricone) and will continue for the foreseeable future.

Advantages: I like how KAVI doesn't hide the science from its customers.

Disadvantages: Even when presented with a wealth of information on a product, it's hard to tell how well something will work on my skin until I try it.
