I have been using the Glycolic Acid 40 for a few weeks now due to dark spots on my arms from the sun. I'm very pleased with how gentle it is. It's effective but there's no burning. I'm seeing some fading - it's slow but I knew that it would be. I'll definitely order again. Also I was happy to find that it's fragrance free. The previous product I was using was less expensive, but the scent was hard to endure.

Advantages: Gradual painless steady lightening of dark spots.

The Kavi Skin Acne system has improved my acne 100%. After going off the pill I had major problems with my skin, but I really didn't want to go back on the pill due to other side affects. After trying so many other skin care lines the Kavi system actually made a significant difference and one i will be sticking with~!

Disadvantages: Can over dry skin initially, you will need to watch for flakiness and adjust the frequency of product application to rectify this.

This product has been a godsend for my son who has been battling cystic acne since the age of 15. After having tried or said no to nearly a dozen different treatment options, we thought we'd try this little company on an earlier suggestion from our dermatologist, and I honestly cannot believe the results I am seeing on my son's face and upper body. In 3 short months, his acne is almost completely gone, and he's excited to be starting his sophomore year in college with this burden off his shoulders.

I imagine results like this won't be for everyone, or KAVI would be a household name, but their sulfur bar worked for us, and I sincerely hope it will work for you.

Advantages: It works well, it works fast

The best acne product ever! ive used so many different kinds, you can name them all! This was the first one to work! I love it!!!!!

Advantages: Everything!

Disadvantages: Nothing!!! Amazing!

I originally used the SA 15 on its own, but it wasn't until I bought the GA 40 peel that I saw a big difference in the appearance of my skin. It's much smoother now and less oily (although no change in pore size yet).

However, it does take a while for it to be noticeable. It has been about a month now (3 wks GA, 1 wk SA).

Burns like the dickens, but it is worth it if you can tolerate it. My skin is slowly regaining its youthful glow....even my husband noticed (and that's saying something!). ;)

I got this to get rid of acne scars. I've used it once so far (I'm taking it slow) and it seems to be doing fine (like, not immediately burning my face to a crisp).

Advantages: Gentle.

Disadvantages: My skin may take a while to get used to it. I think this is just my skin taking its time though.

Great at clearing and keeping breakouts under control after recently stopping antibiotics and ditching BP. I still get some tiny bumps on my forehead, but coupling this product seems to eliminate these too. I would say that the improvement in the skin all over my body has been the most noticeable.

Advantages: Relatively cheap for the quality
Pretty effective
Gentle on my skin

Disadvantages: Slightly difficult to lather
