Copper gluconate detoxifies and purifies skin, drawing excess oils from pores to minimise breakouts and control natural sebum levels. It also has a natural astringent effect, tightening pores for a perfected, mattified appearance. In addition to this, copper is known to activate enzymes that are responsible for the production of collagen and elastin, helping to reduce signs of ageing and boosting firmness. Copper is also often combined with other vitamins and minerals to create rich copper compounds, further enhancing its transformative ability. For instance, the Blue Diamond Resurfacing Peel contains a unique combination of copper, essential amino acids and an anti-glycation phosphate which together help to promote the synthesis of collagen and elastin for a younger looking, fresh complexion.
