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

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.

Love the vitamin c serum

Both items are great but the vitamin c is especially nice. It goes on smoothly, smells divine and leaves my skin feeling great.

Glowy as a glow thing

I absolutely love all of these face care products by Kester Black. They WORK. My skin feels and looks smooth, soft, and I've received more compliments in the last couple of months since using KB serums, than I have in my entire life. I worship at the altar of KB skincare now!

Great results

Good value for money and the results are an even skin tone with a more radiant look. No breakouts like some other brands I've used in the past.
