Tretinoin Review
Tretinoin is a prescription acne treatment also known at this time as Retin-A. It uses a form of retinoids to fight your dead skin cells and help them to shed away at a more efficient rate, also unveiling brighter and more beautiful skin in the process, but mainly being meant to fight against mild to moderate acne vulgaris that you want to deal with.
Pros
Tretinoin has a proven ingredient obviously. Retinoids can give you the skin you want to a certain degree, free of acne and a bit brighter. They have been popularly used for a reason after all.
Cons
It can also cause various skin problems and side effects similar to those of benzoyl peroxide and sometimes extending beyond them. In addition, frankly retinoids can be found just about anywhere, including much cheaper over the counter options.
Conclusion
You would be far better off using something else. Tretinoin is not a product that really measures up to par, and frankly you could easily find something else that is not only faster(meaning greater results in less than several weeks), but also more effective without the same side effects.
