As women approach menopause, their levels of circulating oestrogen start to reduce.
Oestrogen has many important roles in the body. In addition to regulating menstrual cycles, protecting heart, bone and sleep health, oestrogen is also responsible for stimulating collagen production and helping the body retain moisture (amongst many more things!).
Collagen is the most abundant protein in your body and has many important functions - including helping your skin maintain its firmness and elasticity. When collagen levels drop due to a decrease in oestrogen, your skin will also naturally start to have less elasticity and as a result, may become more irritable and dry.
