Glow Duo

(45)

Skincare

A hardworking daily duo for that “wow, your skin is glowing!” effect. In the morning, Daybreak Vitamin C Serum brightens and protects, preparing your skin for the day ahead. At night, Super Retinal Vitamin A Serum works its magic. Our 100% natural retinal acts 11 times faster than retinol to smooth the skin, while niacinamide and peptides firm, plump and brighten. 

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

DAYBREAK VITAMIN C SERUM

  • Protects against free radical damage
SUPER RETINAL VITAMIN A SERUM 
  • Reduces the appearance of lines and wrinkles 
  • Improves texture and tone 
  • Boosts skin elasticity

AM - After cleansing, apply 1 pump of Daybreak Vitamin C Serum to hands and press lightly into face and neck, avoiding the eye area. Wait a few minutes before applying other serums then finish with moisturiser. 

PM - After cleansing, apply 1 pump of Super Retinal Vitamin A Serum to hands and press lightly into face and neck, avoiding the eye area. Wait a few minutes before applying other serums then finish with moisturiser. Always use broad-spectrum sunscreen the following morning. 

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.

I love these!

I really love this set because it came with one that’s perfect for daytime and one that’s perfect for nighttime. Both serums are incredible a little goes a long way and quality like this i is very hard to come by!

I’m already noticing really positive results after a couple of weeks use!
