The Korean philosophy

The Bohr Effect — when CO2 levels increase on the skin surface, your body sends MORE oxygen to that area. Korean beauty hacked basic physiology into a facial treatment.

The ritual

Cleansing

5 min

A gentle cleanser removes all surface oils and residue so the carboxy gel makes direct contact with clean skin for maximum CO2 absorption.

Gel application

3 min

A thick, cool gel is spread evenly across the face. This is the base layer that will react with the activating powder.

Powder activation

2 min

A fine powder is pressed onto the gel layer, triggering the CO2 reaction. You’ll immediately feel fizzing and tingling on your skin — like tiny champagne bubbles. The sensation is unusual but not painful.

CO2 activation period

20 min

You lie still while the CO2 reaction works. The tingling continues as your body responds by sending oxygen-rich blood to the surface. Your face may feel warm as circulation increases. This is the Bohr Effect in action.

Mask removal

5 min

The gel-powder mixture is gently removed with warm towels. Underneath, your skin is flushed pink from the increased blood flow — this is the desired response.

Centella calming

10 min

A centella asiatica serum and cool compress calm the skin and reduce the flush. The redness transitions to a healthy, bright glow within a few hours.

Your first time

The fizzing sensation is the most distinctive part — it feels like your face is covered in tiny sparkling bubbles. It’s tingly but not painful, usually a 2/5 at most. Your face will be visibly pink when the mask comes off — this is normal and means it’s working. The pink fades within 2-4 hours and leaves behind a noticeably brighter, more even complexion. Great for a quick treatment before an evening event.

When to book

Book 4-6 hours before an evening event for peak brightening. The redness fades and the glow emerges beautifully by evening. For maintenance, every 2-4 weeks builds cumulative brightening. Avoid right before photos — the mild redness needs a few hours to settle.

East vs West

The carboxy CO2 mask is a uniquely Korean treatment that leverages basic physiology (the Bohr Effect) at an accessible price point. Western alternatives either use oxygen facials (which push oxygen IN rather than triggering the body’s own response) or CO2 lasers (which are dramatically more expensive and involve downtime). The Korean approach is elegant in its simplicity.

Aftercare

Mild redness is normal and fades within 2-4 hours. Avoid harsh actives for 24 hours. Moisturize well and wear SPF — your skin is temporarily more receptive to both products and sun.
