Skincare

A hardworking daily duo for that “wow, your skin is glowing!” effect. In the morning, The Caretaker Vitamin E Serum calms and nourishes while helping to even tone and protect against environmental stressors. Its blend of Vitamin E, C and F supports barrier strength and radiance, 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 The Caretaker Vitamin E 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.

Better value than what I was using

I switched to this when I first started buying KB after getting a sample. It feels lovely on, and I’ve replace it (and all the other serums) from what I was using. Better value and the packaging is awesome

Brightens skin

This feels like a dose of sun-kissed orange vitamins going on my skin! I love putting this product on. A small amount is very effective to brighten the skin, with results noticeable in a few weeks.
