Chlorella is a single-cell green algae.
Chlorella Growth Factor contains 10,000 mg per 100g of RNA, the highest source available for your skin which boosts the skin's ability to produce new cells and is also clinically proven to protect collagen and elastin fibres from the enzymes that destroy them - the key to reducing the signs of ageing.
According to Acure Organics "clinical studies have shown Chlorella Growth Factor to increase collagen expression by 333% when used at 1% concentration."
