Definition

What is Barrier Banking?

Barrier Banking is a daily skincare habit of making small, steady deposits into your skin barrier, a gentle salmon DNA cleanse, serum, a moisturiser that locks moisture in and daily SPF, so your skin holds up and looks its best on the days that take more out of it.

The term was originated by Sam Thompson, founder of Salmon DNA Australia on the Gold Coast, in 2026. Also written as barrier banking.

What is Barrier Banking?

Barrier Banking is a daily skincare habit of making small, steady deposits into your skin barrier, a gentle salmon DNA cleanse, serum, a moisturiser that locks moisture in and daily SPF, so your skin holds up and looks its best on the days that take more out of it.

Who originated Barrier Banking?

Barrier Banking was originated in 2026 by Sam Thompson, founder of Salmon DNA Australia on the Gold Coast, as part of The Salmon DNA Method alongside PDRN Stacking and Barrier Loading.

What counts as a withdrawal?

Anything that takes moisture out of your skin: aircon and heaters, long flights, late nights, hot showers, summer sun, salt water, chlorine and harsh scrubs.

Is Barrier Banking a treatment?

No. It is an everyday care habit that helps skin stay hydrated, soft and healthy looking, using cosmetic products.

How long until I notice a difference?

Banking is about consistency. Give a steady routine at least four weeks to judge how your skin looks and feels.
