Acne is a disease of the sebaceous gland hair follicles that can present in various forms of lesions. The causes of acne are diverse, including hormonal, digestive, and bacterial factors. Sensitive skin occurs when the skin’s natural barrier is compromised, leading to increased water loss and easier penetration by external agents. Improper skin care can exacerbate acne and sensitivity. Dr. Vi Anh from the Department of Dermatology – Skin Aesthetics at Ho Chi Minh City University of Medicine and Pharmacy Hospital identifies 10 common skin care mistakes that can increase these issues. These include improper cleaning habits, using harsh products, leaving makeup remover on the skin, not moisturizing oily skin, and using too much acne medication. It is important to tailor skin care to different areas of the face, avoid overusing products, and not preemptively pursue anti-aging treatments. Understanding and correcting skin care mistakes early can improve the health and appearance of the skin.
