During the Tet holiday, skin is particularly vulnerable to irritation and chronic dermatitis flare-ups due to various environmental and lifestyle factors, according to Dr. Vo Thi Tuong Duy, a specialist in dermatology and cosmetic dermatology at Tam Anh General Clinic, District 7. The air quality often deteriorates during this festive period from incense smoke, votive paper burning, firecrackers, fine dust, and dry weather. Microscopic particles like PM2.5, heavy metals, and volatile organic compounds can penetrate the skin's protective barrier, leading to inflammation, oxidative stress, and silent inflammatory responses that exacerbate underlying skin conditions.

Compounding these environmental stressors, common Tet lifestyle habits such as late nights, consuming spicy foods, excessive alcohol, and insufficient water intake dehydrate the skin, increase oil production, and weaken its natural defenses. This combination makes skin more prone to redness, itching, acne, or flare-ups of conditions like contact dermatitis and atopic dermatitis, especially for individuals with sensitive or already compromised skin barriers.

To mitigate these risks, Dr. Duy advises limiting prolonged exposure to areas where incense is burned. Prioritize well-ventilated spaces, open windows, or use exhaust fans and air purifiers to reduce smoke accumulation indoors.

When outdoors, apply broad-spectrum sunscreen with SPF 30 or higher. Wear clean, soft, breathable masks to minimize skin friction and irritation. Individuals with sensitive skin can further protect themselves with wide-brimmed hats and sunglasses to reduce direct exposure of fine dust and smoke to the face.

Regularly cleanse skin after exposure to smoke and dust, and moisturize consistently both morning and night.

Late nights, disrupted routines, and stress during Tet can interrupt skin regeneration. A weakened skin barrier makes skin more reactive to environmental factors like incense smoke and fine dust. Therefore, maintaining a proper sleep schedule, getting enough rest, and avoiding continuous late nights are crucial for skin recovery and reducing the risk of dermatitis flare-ups. Additionally, limit excessive alcohol consumption and oily, spicy foods, which can increase inflammation, leading to redness, itching, and acne.

Individuals with a history of atopic dermatitis, contact dermatitis, or those undergoing treatment for acne or melasma must exercise particular caution during Tet. Adhere strictly to prescribed treatment plans and avoid self-discontinuing medication or changing skincare products during this period.

According to Dr. Duy, irritation from incense smoke and fine dust does not always manifest severely at first. Many cases present with only mild stinging, dull skin, or transient tightness. If these symptoms persist, spread, or are accompanied by inflammatory acne or significant peeling, patients should consult a dermatologist or cosmetic dermatologist at a hospital for timely examination and treatment to prevent prolonged complications after Tet.
