Zinc PCA brings together two things skin likes: zinc, a mineral long used for oily skin, and PCA, part of skin's own moisturizing system.
What Is Zinc PCA?
Zinc PCA is the zinc salt of pyrrolidone carboxylic acid (PCA). PCA is a key component of skin's natural moisturizing factor, while zinc is a mineral used in skincare for its balancing properties.
A 2014 review in Dermatology Research and Practice summarizes the long use of zinc compounds in dermatology, including topical zinc for oily and blemish-prone skin.
What It Does for Skin
Helps balance oil. Zinc is widely used to help manage the look of excess shine, so skin looks more balanced through the day.
Helps pores look smaller. When shine is under control, pores tend to look more refined.
Supports hydration. The PCA part helps skin attract and hold moisture, so oil control doesn't come at the cost of comfort.
Adds antioxidant support. A 2012 laboratory study in the International Journal of Cosmetic Science found that zinc PCA helped limit UVA-induced breakdown of collagen-degrading activity in cultured skin cells.
Where You'll Find It at True Colour Beauty
The Blemish Care Daily Moisturizer and the Oil-Free Hydrating Gel Moisturizer use Zinc PCA for balanced, lightweight hydration.
For hair, the Keratin Volume Boost Shampoo and Keratin Volume Boost Conditioner include it to help the scalp feel fresh.
How to Use It
Use Zinc PCA moisturizers after cleansing, morning and evening. They pair well with niacinamide, salicylic acid and kaolin-based products. Wear sunscreen during the day.
What the Research Doesn't Say
Some zinc research uses oral zinc or different zinc compounds. Zinc PCA in a moisturizer works on the look of shine and balance and won't change skin overnight.
