Why you'll love it:

  • Round-the-clock radiance & hydration
  • Day-long protection against environmental stressors
  • Overnight skin firming & brightening
  • Suitable for all skin types, even sensitive skin

First-timers: Use twice a week at night for two weeks. Gradually build skin tolerance and use every alternate night for another two weeks, and then nightly, or as needed to suit skin tolerance.

Advanced users: Use nightly. 

Note: Ascorbic acid and retinal are powerful ingredients and can cause irritation when used together at once. We don’t recommend applying them at the same time.

Changed my life

I was diagnosed with melasma a few years back and I had tried everything try to get rid of it with my dermatologist-bleaching creams, lasers, micro needling, expensive products etc.

NOTHING worked. I found your products vitamin C and retinal about a year ago and decided to give it a go because it was such a good price point. My melasma has completely gone away since using it and has not returned. Whatever you are doing, do not change the formula of these products. I can do grateful for them as it changed my life.

Smoother skin and improvement to acne scars

I have been quite impressed with both the products in the Glow Duo.

I have been using the Daybreak Vitamin C Serum daily first thing after a shower and I let it rest before applying 50+ sunscreen and any make up. A light and easy to apply product.

I am feeling most impressrd with the Super Retinal Vitamin A Serum and I started using it every other night as it is my 1st retinal use. My skin is smooth and my acne scarring near my mouth from hormones is reduced and really gone.

I will continue using them both.

Stunning results

Wow! If you’re chasing a “glow” & want refined dewy skin, this will deliver! I’m into my 2nd order of this duo & now it’s in my staple skincare plan. I’m now also using the KB moisturiser (only for 2 days now) & omg!!!! What a combo that’s delivering amazing skin. The products are fabulous & the customer service is second to none!
