REN Radiance Perfection Serum contains Liquorice and Wild Canadian Rumex. These aim to regulate the production of melanin and haemoglobin, to reduce pigmentation and redness.
Yeast helps to stimulate the formation of ATP to encourage metabolism and give radiance. Yeast also improves water retention and replenishes tissues.
To use: Apply under moisturiser in the morning and under night cream in the evening.
