It primarily appears on areas frequently exposed to sunlight such as the face, neck, and shoulders.<\/p>\n<p style=\"text-align: center;\"><b>\u1ea2nh da b\u1ecb n\u00e1m t\u00e0n nhang\u00a0<\/b><\/p>\n<p style=\"text-align: center;\"><i><span style=\"font-weight: 400;\">Melasma affects appearance and causes women to lose confidence<\/span><\/i><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">According to the American Academy of Dermatology (AAD), 90% of melasma cases occur in women aged 20 to 50, especially during pregnancy and postpartum periods. The condition may fluctuate over time, intensifying in summer and fading in winter.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Causes_of_Melasma_and_Freckles_in_Women\"><\/span><b>Causes of Melasma and Freckles in Women<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Many women wonder about the causes of melasma and freckles. These spots can result from multiple factors, including environmental and genetic influences, detailed as follows:<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Genetic_Factors\"><\/span><b><i>Genetic Factors<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Scientific studies show that if melasma or freckles occur in your family, especially in your mother, you have a higher risk of developing them. People with genes that regulate strong melanin production or sensitive skin to environmental effects are more prone to melasma than those without such genetic factors.<\/p>\n<p>Thus, genetics is one cause of melasma.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Hormonal_Changes\"><\/span><b><i>Hormonal Changes\u00a0<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Hormonal changes are the main cause of increased pigmentation, leading to more melasma and freckles. When hormones like estrogen, testosterone, and progesterone are imbalanced, the skin becomes more sensitive to environmental stimuli. This stimulates excess melanin production, causing dark patches and spots.<\/p>\n<p style=\"text-align: center;\"><b>\u1ea2nh da b\u1ecb n\u00e1m t\u00e0n nhang<\/b><\/p>\n<p style=\"text-align: center;\"><em>Hormonal changes are a major cause of melasma<\/em><\/p>\n<p>Common cases include:<\/p>\n<ul>\n<li>Birth control pills: Alter hormone balance, making skin prone to melasma.<\/li>\n<li>Hormonal disorders, hypothyroidism: Affect hormone production, increasing pigmentation.<\/li>\n<li>Pregnancy: 15% to 50% of pregnant women develop melasma due to hormonal shifts.<\/li>\n<li>Postpartum and menstrual irregularities: Reduced estrogen causes decreased skin elasticity, promoting melasma development.<\/li>\n<\/ul>\n<p><strong>Click here: <a href=\"https:\/\/hbioclinic.com.vn\/en\/cach-phan-biet-cac-loai-mun\/\">C\u00e1ch ph\u00e2n bi\u1ec7t c\u00e1c lo\u1ea1i m\u1ee5n<\/a> tr\u00ean m\u1eb7t v\u00e0 nguy\u00ean nh\u00e2n g\u00e2y ra<\/strong><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Age_Factor\"><\/span><b><i>Age Factor<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Age is another cause of melasma. Estrogen plays a critical role in regulating melanin production. During perimenopause and menopause, estrogen levels drop, causing pigmentation disorders and increased melasma and freckles.<\/p>\n<p style=\"text-align: center;\"><b>\u1ea2nh ph\u1ee5 n\u1eef cao tu\u1ed5i b\u1ecb n\u00e1m da<\/b><\/p>\n<p style=\"text-align: center;\"><em>As women age, hormonal changes and skin aging make the skin more prone to melasma<\/em><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Additionally, aging reduces collagen production, leading to thinner, weaker skin more vulnerable to environmental damage, worsening melasma.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Sun_Exposure\"><\/span><b><i>Sun Exposure<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Sunlight contains UV rays that penetrate the skin, damaging cells and causing irritation and burns. Frequent sun exposure without protection triggers melanin production as a defense, leading to melasma and freckles, especially on the face.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Use_of_Low-Quality_Cosmetics\"><\/span><b><i>Use of Low-Quality Cosmetics<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Using poor-quality cosmetics also contributes to melasma. Many women use unregulated whitening creams or unknown-origin products, which may initially lighten skin and reduce melasma. However, over time, these products erode the skin barrier, making it weaker and more sensitive to UV rays, pollution, and other environmental factors. As a result, melasma and freckles worsen.<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Unhealthy_Lifestyle_and_Chronic_Stress\"><\/span><b><i>Unhealthy Lifestyle and Chronic Stress<\/i><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">Unhealthy habits such as staying up late, lack of sleep, prolonged stress, little exercise, or overwork can disrupt hormone balance and the autonomic nervous system. This imbalance stimulates melanin production, causing melasma in many people.<\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Effective_Prevention_Methods_for_Melasma\"><\/span><b>Effective Prevention Methods for Melasma<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Early treatment combined with proper skincare and protection can quickly improve melasma.
