Chemical peels are brilliant. I am fair skinned and personally I wouldn't bother with the 12.5 or 15% TCA peels, they do very little. I started with a 30% TCA blue peel (£800) and the results were amazing. I followed up with another 30% TCA ordinary peel that cost £200 the year later and had another good result.
This can become expensive so I've tried TCA home peels and they work just as good. I use 20% concentration but layer it on 3 times. It can be pain full,but your skin is glowing after wards.
