Glycolic Vs. Salicylic Acid - Which Peel is Better for Acne?

I have light to moderate acne, and a friend suggested that I start getting monthly chemical peels.  I've read up on glycolic acid peel and salicylic acid peel but they seems so similar I don't know which one would be a better acne treatment.  Please tell me which one works best.

Salicylic acid slightly superior

+5
You are asking whether the alpha-hydroxy acid, Glycolic acid, or the beta hydroxy acid, salicylic acid is superior. In this case I am going to have to go with the Beta dog, sal acid.
A study published in Dermatologic Surgery last year compared the two types of peels and gave the nod to the salicylic acid peel. This study, performed by dermatologists at the St. Louis University confirmed the impression that most dermatologists have had for years: that the Beta peel is preferred for acne and the glycolic peel for skin lightening and rejuvenation.
The results of the Beta hydroxy acid peel (BHA) lasted a bit longer and had fewer side effects such as irritation. Both peels were effective in reducing acne lesions, however.
This was the only study I am aware of that compared these two peels.
Usually the beneficial effect of the peels occurred in about two weeks.

Salicylic acid peels typically better for acne

+4

Typically, Salicylic acid peels are better for acne, but glycolic peels in higher concentration can be also very effective. Sometimes, alternating them is a good idea to see how your skin will respond to each of them. Remember that a series of peels will be necessary and maintenance peels to keep your acne under control. Usually not one peel or treatment works for acne, so multiple different treatments, sometimes combined with prescription medication will help.

Acne and Salicylic Acid Peels

+3

Salicylic acid peels penetrate deeper into the oil gland than the glycolic acid peels do, and cause less inflammation on your face---so go with the Salicylic acid.  It comes in a number of different strengths, and can be customized just for you.  You might also speak with your dermatologist about using some prescription topical medications at home every day to maximize your best skin.

Salicylic acid or glycolic acid for acne

+3
Both of these acids are used for minor "peels" and often used as "adjuvants" for treating acne. However, not convinced that either alone are any more beneficial than the other. To be most effective , either glycolic or salicylic need to be combined with an appropriate acne regimen that consists of prescription creams and oral antibiotics for more severe cases.

Sal Acid Peel

+2
For Acne, a Salicylic Acid peel will help decrease oil and help cause P. Acne bacteria death, thus decreasing acne. This is often the best treatment for active acne however Glycolic acid is a good treatment for anyone who also suffers with acne scars. Sal Acid helps better penetration of follicules and pores which also cna make medication absorb better into the skin.

Both Superficial Peels

+2

Both of these are superficial peels. Glycolic acid is the stronger of the two, so generally, I have more success with it. Both can help with papules and pustules of acne.

Salicylic acid is really mild….really, really mild. While there can be some mild improvement in acne and skin texture, the penetration of salicylic acid makes the impact very low. It also makes the downtime very low, usually just an hour of redness. If you can tolerate a few hours of redness, I’d recommend beginning with glycolic acid. It’s still a superficial peel, but has shown much better activity against both the bacteria that causes acne as well as black/whiteheads (called comedones). You’ll need fewer treatments and get better results.

Salicylic acid better for lighter skin types, Glycolic better for darker skin types

+2

Generally, I prefer salicylic acid peels for patients with lighter skin types.  For patients with darker skin types, who have acne, they usually also want to lighten dark spots left behind from acne spots.  Glycolic acid peels are best for patients with darker skin tones, since they even out pigmentation and treat acne.

Chemical peels

+1
Both salicylic and glycolic peels are very effective for treating acne and acne scars. Generally we prefer to start with salicylic peels which come in varying concentrations, especially if you are new to the world of chemical peels. Glycolic peels tend to be a little stronger and are used after a series of salicylic peels has been completed

Salicylic acid

+1
Hello,


A salicylic acid peel is a great option for active acne.  Glycolic is a good peel as well, overall good peel to exfoliate the top layer of dead skin.  Salicylic acid is better for acne patients.  It is a derivative from aspirin to help heal and dry out active acne.  We usually like to start our patients on a four step acne kit, after about two weeks we do a chemical peel altered to their skin type.  We us PCA chemical peels which are blended peels designed for specific skin types.  We also do a 6 treatment package.  Usually the patient needs about 3 customized chemical peels, and 3 laser light resurfacing treatments.  Again, to answer your question, salicylic acid is better for acne.

Salicylic versus glycolic Peel

+1

It is the physician who decides which peeling agent will help help her/his patient for her/his specific needs.

I prefer salicylic acid over glycolic acid for its better penetration, safety & results.

Also, it needs generally 6-8 sessions of peeling for significant results.

Please follow your physician for proper assessment & better management.
