Improper hair removal techniques, such as using dull razors, shaving against hair growth, applying excessive force, or unsanitary tools, can cause microscopic abrasions and damage hair follicles. When skin is already irritated, its natural protective barrier weakens, allowing bacteria to easily penetrate hair follicles, leading to inflammation, redness, itching, and pus-filled bumps around the follicles. Master, Doctor Vu Thi Thuy Trang, a specialist in Dermatology - Aesthetic Dermatology at Tam Anh General Hospital Ho Chi Minh City, explained that this was the case for Ms. Mai, 25, who experienced widespread irritation after improper hair removal on multiple areas, particularly on already sensitive skin.

Ms. Mai was diagnosed with infectious folliculitis. Doctors prescribed oral antibiotics and anti-inflammatory medication, combined with topical treatments. She also received instructions on proper skin care, including using a gentle body wash for cleansing.

After two weeks of treatment, the inflammation subsided, and the bumps flattened. However, significant post-inflammatory hyperpigmentation remained, particularly on her back and legs. Doctors then recommended additional treatment with pico laser for 6-10 sessions, bi-weekly, to fade pigmentation and restore the skin's surface.

Post-inflammatory hyperpigmentation is a common complication when skin is damaged, especially in thicker areas like the back, arms, and legs. If not treated correctly, these dark spots can persist for many months, significantly impacting appearance. Even individuals who have undergone hair removal without issues previously may experience varying skin reactions depending on their current skin condition and the method used. Beyond folliculitis, other potential complications include irritation, skin burns, allergies, or infections.

Doctors advise individuals seeking hair removal to choose reputable hospitals or aesthetic facilities that ensure safe procedures and use products with clear origins. A thorough skin examination is essential before any hair removal to select the appropriate method. Hair removal should be avoided if the skin is inflamed, abraded, or overly sensitive.

Following hair removal, it is crucial to avoid vigorous rubbing, refrain from using irritating products, and monitor for any unusual signs. If pus-filled bumps or persistent pain occur, prompt consultation with a dermatologist - aesthetic dermatologist at a hospital is necessary for timely treatment and to prevent complications such as scarring or stubborn hyperpigmentation.
