Zinc PCA

INCI: Zinc PCA
Balances oilRefines poresSupports scalp

A zinc salt that helps rebalance oil and refine the look of pores on skin, and calm an unbalanced scalp.

What it is

Zinc PCA combines zinc with PCA (pyrrolidone carboxylic acid, itself a natural moisturising factor). The zinc contributes oil-balancing and purifying properties while the PCA carrier is skin-friendly and hydrating, a rare combination of sebum-control and comfort.

How it works

Rebalances sebum

It helps moderate excess surface oil, which over time refines the look of enlarged pores and shine without the tight, stripped feeling of harsh oil-control.

Supports scalp and skin comfort

On the scalp it contributes to a balanced, comfortable base for healthy-looking hair; on skin it purifies while the PCA keeps things hydrated.

The evidence

Zinc PCA is well regarded for sebum regulation and scalp/skin balancing, and is gentle enough for regular use in cleansers and leave-ons.

Works well with

Sits well with Niacinamide for oil and pore concerns, and with amino-acid cleansing systems.

Who it's for

Combination, oily or congestion-prone skin, and anyone with an oily or unbalanced scalp.

Worth knowing

Balances rather than strips, the distinction that keeps oily skin from over-producing in response.
