The impact of hormonal changes on the skin
One of the functions of hormones in our body is to regulate the skin. These hormones are oestrogens, which are female sex hormones and influence hydration, pigmentation, sebum regulation and even the thickness of the skin. Additionally, oestrogens promote the renewal of dermal cells and stimulate the synthesis of collagen and elastin fibres, which are responsible for the skin's elasticity.
Hormones play a crucial role in regulating skin health. They include oestrogens, which are female sex hormones, and play a fundamental role in hydration, pigmentation, sebum regulation and skin thickness. Furthermore, they encourage dermal cell renewal and stimulate the synthesis of collagen and elastin fibres, which are vital for skin elasticity. Understanding these hormonal functions is essential for addressing key aspects of skin health and aesthetics.
Therefore, when we experience a significant hormonal change such as breastfeeding, pregnancy or menopause, the skin systems are also affected.
During menopause, our oestrogen levels drop, leading to a loss of firmness and elasticity, and accelerated skin ageing.
Another period of significant hormonal changes is during adolescence. In this case, it is the excess of testosterone, the male sex hormone, which can cause the appearance of acne, or make our skin oilier than usual.
During pregnancy or breastfeeding, the activation of oestrogens causes the skin to become inflamed, more sensitive and lacking in hydration. It is a period when the skin is more exposed to hyperpigmentation, as hormonal changes stimulate melanocytes. In most cases, chloasma disappears after pregnancy.
