Heightened stress and poor sleep are believed to accelerate the ageing process twice as quickly. Under extreme conditions, skin cells struggle to regenerate (especially at night) which results in a duller complexion and more prone to imperfections – redness, pimples, dry patches.

To help combat this, Yon-ka has released Serum CBD along with a 90-minute face and back sleep therapy ritual which uses the serum and also works on energy points and destressing techniques with aventurine quartz.

"Night after night, defying stress, beautifying the skin, Serum CBD is an absolute must for every evening beauty routine," says product manager Kety Manga.

The star ingredient is pure CBD, dosed at 300mg, grown sustainably in Colombia. The formula also features cells from the sacred lotus flower, an adaptogenic extract from the reishi mushroom, organic oils of hemp and inca inchi and essential oils of lavender chamomile and neroli.
