Dr. Sivak's Notes:

Zinc PCA can decrease the redness and irritation caused by acne and reduce oiliness.

L-pyroglutamate (PCA) is a relatively simple hygroscopic molecule naturally produced by our bodies and one of the skin's natural moisturizing factors.  

• Find it in our ready made Salicylic Wash.

Each tube (10 mL) is enough for 4 fluid ounces of serum.

We recommend that this product not be used in creams but it can be added to our T-Zone Serum or our Sea Kelp Coral. It can also be added to your favorite shampoo and conditioner as a dandruff remedy, although it will thin the formulas.

This zinc salt L-pyrrolidone carboxylic acid (L-PCA), is more commonly known as  Zinc PCA. The mechanism of Zinc may still be a matter of discussion, but there seems to be an agreement that salts of this metal decrease inflammation caused by acne, maybe through inhibition of the enzyme that catalyses the production of dihydroxytestosterone (a hormone that controls sebaceous gland activity). Zinc is also an antibacterial, and its salts are used to control dandruff in “medicated” shampoos.*


Antibiotics can be useful in the treatment of acne, but in some circumstances antibiotics may not be an option and they can be a bad idea for use over long periods of time. We decided that Zinc PCA would be a good addition to our Salicylic Wash. You could also add this active to our T-Zone serum for added moisture and to reduce redness and irritation.*

    Zinc is excellent for acne & oily skin. Calms & normalizes oil production for those of us who are shiny all the time & have trouble keeping a matte complexion. Zinc in other skincare brands has always worked great with regard to sebum. Thanks for offering it to add to products that don't contain it for those of us who need it!

    I've found zinc to also be incredibly healing for acne breakouts. It also reduces older scar tissue, prevents newer scars from developing, greatly reduces inflammation/redness/irritation, encourages new, healthy tissue growth & more. I buy it in bulk & wouldn't be without it.
