Glass Skin Blemish Serum with Retinaldehyde

Finally a breakout formula with results guaranteed! See smoother skin with fewer bumps and pimples in just weeks or your money back.

Meet your skin’s new hero. Inspired by Korean advances in clear skin and powered by science, the K Republiq blemish regime guarantees results in just weeks. The new customer favourite Glass Skin now with our highest concentration of clinically proven Retinaldehyde has results comparable to prescription Retin-A BUT without the harsh side effects.

Retinaldehyde: A gentler yet powerful form of vitamin A that smooths fine lines, boosts collagen, refines skin texture and removes oil to reduce visible breakouts—without the irritation.

Niacinamide: Calms redness, evens skin tone, and strengthens your skin barrier for a healthy glow.

Panthenol: Also known as provitamin B5, this ingredient deeply hydrates and soothes, leaving your skin supple and soft.

Salicylic Acid: A beta-hydroxy acid that works to unclog pores, prevent breakouts, and refine skin texture.

Polyglutamic Acid: This hydration powerhouse locks in non-oily hydration for plumper, dewier skin.

Bearberry Extract & Licorice Extract: Brighten dull complexions and fade the discolouration left by pimple blemishes for luminous, even-toned skin.

How to use

We recommend using the Blemish Serum as part of your nighttime routine only, as some of the active ingredients can increase sun sensitivity.

To allow your skin time to adjust to the powerful actives, start by using Blemish Serum just 2–3 times a week.

1. Wet your face with lukewarm water.

2. Dispense a small amount of cleanser and gently massage onto your face in circular motions using your fingertips.

3. Rinse thoroughly and pat dry.

4. Follow with 2–3 drops of the Glass Skin Blemish Serum.

5. Finish with our Glass Skin Finishing Glaze.

⚠️ Note: You may notice a little dryness at first—this is just the Retinaldehyde gently exfoliating the dull, dry outer layer of skin.

What to expect
In just a few weeks, experience smoother, even-toned skin with visibly fewer pimples and breakouts. In 3 months most people experience over 85% reduction in visible breakouts.
