I have used quite a number of services from Kaya. The underarm hair laser works wonderful. The hair growth became almost nil after only 4 sittings ( the package is for 6-8 sittings depending on the growth/density of your hair). I took it almost 3 years back and it still works. I am very happy with the results.
I am however, not happy with the glycolic peels at all. It makes no difference to your skin. You have to pay a bomb (2k for one sitting, but they will force you to take a package of 10k citing long term results etc.) and the result is only as good as a normal facial which might cost you say Rs. 800. My advice is : NEVER go for a glycolic peel.
