How to prevent acne under the skin.

Subcutaneous acne is difficult to detect and can easily become inflamed and swollen if not treated properly, but it can be minimized with a suitable diet and skincare routine.

According to Dr. Dang Thi Ngoc Bich, a dermatologist at Tam Anh General Hospital in Ho Chi Minh City, hidden acne is acne that develops beneath the skin's surface, usually caused by cysts or nodules, and does not have a visible head. Unlike whiteheads and blackheads, hidden acne develops closer to the skin's surface. Most hidden acne is difficult to see with the naked eye and can only be felt as a raised bump on the skin. The area containing hidden acne is often painful, slightly inflamed, and red.

The key to preventing acne is to build a healthy diet, maintain a balanced lifestyle, and practice regular hygiene and skincare.

Regarding diet, limit spicy, sugary, or fatty foods, and focus on incorporating foods rich in omega-3, omega-6, and vitamins into your meals; limit the consumption of caffeinated beverages and stimulants such as coffee, alcohol, and beer.

A healthy lifestyle also helps prevent acne, including maintaining a regular routine, avoiding staying up late, and refraining from touching your face with unwashed hands.

In addition, people need to pay attention to hygiene and skincare by washing their face twice a day and ensuring their bodies are clean after exercising or in hot weather.

People need to learn about and use gentle, non-irritating cosmetics, and limit the use of cosmetics containing alcohol. Remember to use sunscreen, hats, and sun-protective clothing when going out in the morning, noon, and afternoon.

According to experts, hormonal changes and imbalances are the leading cause of hidden acne. Hormonal changes stimulate the sebaceous glands to produce large amounts of oil, which combines with dead skin cells and dirt from the external environment to form hidden acne lesions. In addition, an unhealthy liver or impaired liver function also makes it less effective at filtering toxins, indirectly causing hidden acne to appear.

Certain environmental factors such as high temperatures, dust, and oil can irritate the skin and cause hidden acne. Improper skin hygiene leads to clogged pores and creates opportunities for hidden acne to appear. The skin needs to be thoroughly cleansed, combining makeup removal and facial washing to eliminate all the main causes of hidden acne, such as dead skin cells, excess impurities from cosmetics, and dirt.

Approximately 50-80% of subcutaneous acne cases resolve spontaneously within a few weeks to a few months. However, the longer the acne persists, the more damage it causes to the underlying tissue. In some people, subcutaneous acne, when damaged, leads to hyperpigmentation (pink, red, or brown scars). In others, long-standing, untreated subcutaneous acne is more likely to progress to acne vulgaris, causing pitted or atrophic scars. Atrophic scars typically appear as a pit or depression due to collagen damage in the skin.

Dr. Dang Thi Ngoc Bich advises that squeezing pimples does not speed up the healing process and can even cause more severe inflammation, enlarge the pimple, push the pus deeper, and create post-inflammatory dark spots.

For cases of hidden acne that are swollen, inflamed, or do not improve over a long period, people should visit a reputable medical facility to be examined and treated by a dermatologist or cosmetic skin specialist. Currently, some common methods include: using topical antibiotics to eliminate bacteria causing hidden acne and reduce inflammation. Benzoyl peroxide helps dry out acne lesions and, when used in conjunction with topical antibiotics, enhances treatment effectiveness.

If there are too many hidden pimples or signs of infection that turn into acne or inflammatory pimples, the doctor will prescribe oral antibiotics.
