What's the difference between all the chemical peels?

I have a moderate amount of red/brown marks and mild scarring on my cheeks and am planning to dilute a 25% TCA peel to 12.5%. However, I've read about the other peels and they all seem to do the same thing? So, what's the difference between them if there are any? Is it just strength of the chemical/how often you will need to apply it?

Is it also true that I cannot use peels if I still have existing active acne?

TCA Peels-

"Medium chemical peels are highly effective in promoting skin smoothness and vitality. They also improve superficial discoloration and eliminate fine wrinkles. They do nothing for acne scarring or dynamic wrinkles. Medium depth peels can be achieved with a variety of chemicals. TCA (trichloro acetic acid) is the most common. Jessner’s solution, glycolic acid, salicylic acid, and other agents are also used."

Glycolic Acid Peel -

"Glycolic acid works as an exfoliating agent because of its high acidity but easy solubility. When placed on the skin as part of an exfoliating cream or gel, glycolic acid goes under the damaged upper layers of skin and destroys the 'glue' which holds dead skin to the surface. As this dead skin is chemically burned off, the other ingredients carry the individual flakes away and a water rinse neutralizes the remaining acid. The result is a much-smoother skin surface and a more youthful appearance. A secondary benefit is glycolic acid's ability to draw moisturizers into the newly-exfoliated skin surface. This is why cosmetic counters often sell a complete system of skin care; the rest of the alpha-hydroxy line contains moisturizers and neutralizers to counteract the corrosive actions of glycolic acid."


Salicylic acid peels -

"Salicylic acid is lipid soluble; therefore, it is a good peeling agent for comedonal acne. The salicylic acid is able to penetrate the comedones better than other acids. The anti-inflammatory and anesthetic effects of the salicylate result in a decrease in the amount of erythema and discomfort that generally is associated with chemical peels. The most common concentration used today is 20-30% and can be purchased in easy-to-use kits."


Lactic Peels -

"After having beat acne, it left my skin with red/black brownish spots and luckily, this is the first product I came across. I started using it a month ago and now I have little or no redmarks left where I had it the most. The only con I experienced is the peeling on the 2nd day after I applied the peel."

"Less acne, scars fading!"

"little to no redness(what redness i had was gone in less than two hrs)

the peel was just a little uncomfortable on my skin

after one treatment i can already tell a difference"


Looks to me like they all do something different with the acne symptoms. :shrug:
