This is a great retinol product. Very nice and smooth consistency that is not drying. This is a great serum for sensitive skin, and it's been working pretty well for around the eye area as well.

This has drastically helped my hormonal acne that has been resistant to other forms of treatment. It really speeds up the healing process and for me, also helps to fade dark spots faster.

Advantages: Works very well for resistant acne
Works faster and better than other treatments

Disadvantages: Dries out skin. However, I wouldn’t recommend following up with a moisturizer because it reduces its effectiveness. If it’s too drying, Apply a smaller amount, less often or when you don’t mind or won’t notice the dryness (eg at night before bed or just relaxing at home).

I get bumps on the back of my neck and lower head.. they come in waves and can last several weeks. They seem to enjoy forming right over nerves and can be very painful. I discovered this product a few months ago and it has improved my recovery rate from these bumps pretty dramatically.

After a shower, I dry my hair and then douse a paper towel with the 25% concentration and then rub it into my scalp and neck for about 30 seconds and then leave it alone. If I do this for a couple of days, the bumps are gone in about three days. I know this probably isn't the best application method, but it's quick and easy, and it works.

Advantages: great for acne or anything else that might be clogging your pores and creating painful, stubborn bumps.

I could see an improvement the morning after my first peel. I bought this product to help with uneven texture on my back from old acne. It's been eight weeks now, and my skin looks new and clear. My back doesn't look perfect yet, but it looks 10x better than before, and I'm a lot more comfortable wearing swimsuits and open back tops. Wish I would have bought this back in the spring so I'd be where I am now when summer just started.

Advantages: I can buy it online, instructions are complete, and the phone support is excellent.

Disadvantages: This was my first home peel, and the stinging sensation the first two peels was a little scary, as I didn't know what to expect. There's redness after I wash off the peel, but it seems to last only about 30 minutes.

I had probably spent something like $1500 getting in-office treatments for my keratosis pilaris before I had a light bulb moment and decided I could do the same treatment at home for less. After having had the treatments done professionally, I felt I knew the steps well enough to try it on my own, and I am so happy I made the switch. This KAVI product is the only one I've purchased, but it's exactly what I need. There has been no increase in new KP outbreaks, and existing lesions are healing at the rate I was hoping for.

Advantages: Strong enough for KP on the arms and legs without being too harsh. Inexpensive given the alternatives. Comes straight to my mailbox.

Disadvantages: None, but I saw a professional do it a few times before I felt confident to try it on my own.

This is the only cleanser that leaves me feeling clean without drying me out. I've searched the world over for a wash that doesn't trigger my allergies but can still clean my skin, pores included.

Advantages: Cleans without drying or triggering allergies; includes glycolic acid for anti-aging.

Disadvantages: None that I can think of.

Finally - a cleanser that works for my skin! I started using Kavi products last November. What a difference in my skin! I have tried numerous other cleansers but never felt they got my skin really clean. Using the Glycolic Cleanser 10 in conjunction with the Kavi Toner has resulted in massive improvements in my skin.

Advantages: Cleanses well but does not strip my skin. I use this with Kavi Toner, Enhanced Retinol and Glycolipidic Moisturizer.

Disadvantages: None.

Would like to go to 50 on the glycolic peel if 40 doesn't banish sun spots, but I realize it takes several weeks to show improvements.

Advantages: Will be good value once it works.

Disadvantages: It's not working as fast as I had hoped.
