I am writing this review to encourage those who has stopped isolaz after their first treatment or second treatment to give it more time and keep continuing. However, do not rely on it entirely, get your doctor to prescribe you with retin a, topical antibiotics and oral antibiotics. This is going to get to the root of the problem of ance. You are probably gonna start doubting yourself along the way but just keep going. This might seem like a really long journey but just hang in there. It will be worth it. A few months of suffering for entirely clear for life after that is so worth it. Remember to never stop using retin A if you do use it. Also, it will be great if you could maintain with monthly isolaz even after your skin clears up. In the meanwhile, go for isolaz every 2 weeks till you clear up. In fact, you could speak to your dermatologist about alternating chemical peel and isolaz. As isolaz vacuums out all the debris from your pores while chemical peel is deep exfloliating your skin. the action together makes it very superior and quick to clear up the skin entirely. The only reason i am giving this treatment 4 stars is because i do think it is very expensive. Also, i have tried carbon peel to help deep cleanse my skin but this is really nothing as compared to isolaz.
