(Peri)menopause can change the way your skin looks and feels – skin dehydration in menopause is a common symptom that many women experience. During perimenopause, your oestrogren levels begin to drop and your skin’s collagen production slows. As your skin is 75% collagen, the decline in collagen production leads to a loss of thickness, firmness and elasticity. Studies show that skin loses around 30% of its collagen throughout the first five years of menopause, followed by an annual 2% decline for the next 20 years.
