The method of soaking in warm salt water combined with deep moisturizing using coconut oil for skin conditions – originating from the article "10 Golden Rules for Raising Healthy Children" by Mr. Nguyen Trong Hung (Owner of the Nam Duoc Lao Nha Que brand) – has spread widely in the community due to its simplicity, ease of application, and many positive reviews.

In the article, Mr. Hung instructs on preparing a 2–2.5% saline solution (about 0.4 kg of salt in 20 liters of warm water), soaking the skin for 15–20 minutes, and not rinsing with regular water to retain the mineral layer. Young children need to be given warm water during soaking to avoid chills. Afterwards, apply pure coconut oil 4–6 times daily to dry, itchy, or irritated skin to increase moisture and soothe.

The mechanism of action of coconut oil and warm salt baths helps treat skin conditions.

Both traditional and modern medicine recognize coconut oil as having moisturizing, softening, antibacterial, and skin-restoring properties; while warm salt water helps cleanse, reduce itching, and stabilize the skin's surface.

Why is a salt concentration of 2–2.5% so effective?

International studies on saline bathing therapy show that concentrations of 1–5% can regulate osmotic pressure, reduce water loss, and restore the structure of the stratum corneum. Within this range, concentrations of 2–2.5% are considered most suitable for mild disinfection, reducing inflammation and itching, while remaining safe for sensitive skin and young children. This is also mentioned in research on the treatment of atopic dermatitis at the University of Kiel (Germany), reported in the International Journal of Dermatology , and in analyses related to hypertonic saline solutions in the care of dry skin.

The mechanism of improvement with warm salt water.

– Stabilizes skin pH and reduces the activation of inflammatory cytokines.

– Reduces transepidermal water loss by increasing lipid binding in the stratum corneum.

– Helps inhibit certain strains of skin bacteria such as Staphylococcus aureus.

– Softens the stratum corneum, allowing nutrients to penetrate better.

The role of coconut oil in skincare.

Coconut oil contains lauric acid, capric acid, caprylic acid, along with polyphenols and natural vitamin E (tocopherol). These components help lock in moisture and reduce water loss by creating a light lipid film on the surface, reducing inflammation, supporting antibacterial and antifungal properties, and increasing the softness and elasticity of chronically dry skin.

Coconut oil is used for massaging, moisturizing, and protecting the skin of young children.

Research conducted by the Center for Clinical Pharmacology – Hanoi Medical University on coconut oil products from Vi Dieu Nam Pharmaceutical Co., Ltd. showed moisturizing, softening, and wound-healing effects in a chronic ulcer model and supportive treatment of burns in experimental settings. These are preliminary experimental results and require further comparison with clinical data.

Feedback from the community

Many parents say they readily accept the method of bathing their children in warm salt water combined with coconut oil because the ingredients are familiar, safe, and virtually free of side effects. Many begin with the simple thought: "If I try it, I'm not afraid, maybe it will work," and this initial cautious experiment often yields surprising results.

In "The Story of Salt Baths That Started a Love Story," Loan Hieu Thuong recounts how her child suffered from persistent heat rash, and despite trying many methods without success, the condition improved. After applying the salt bath method suggested in "10 Golden Rules for Raising Healthy Children," the rash subsided on the first day and almost completely disappeared the next day. The family maintains daily salt baths, especially in winter, to keep the baby's skin soft and smooth.

The community shares information about using warm salt baths and coconut oil massage in the treatment of skin conditions.

Ms. Duong Huyen and Ms. Lan Anh also noted a significant improvement in their children's fungal skin infections, rashes, and dermatitis when combining warm salt baths with coconut oil application. The rapid, safe, and easy-to-implement improvement has led to the continued spread of this method among groups of parents with young children.

Although generally positive, the response rate can vary depending on individual sensitivities. Using the correct salt ratio and pure coconut oil can help minimize irritation. In cases of extremely sensitive skin, increased redness, or no improvement after a few days, parents should take their child for a check-up to avoid overlooking other medical conditions.
