In a world full of colorful advertisements and "essential" baby cosmetics, it's easy to fall into the trap of overzealousness. However, when it comes to caring for our youngest little ones, moderation is often the best policy. We spoke with a distinguished expert, Prof. Andrzej Kaszuba, MD, PhD, about how to care for newborn and infant skin, how to avoid common mistakes, and why traditional baby oil isn't always a good idea.
Professor Andrzej Kaszuba has been involved in pediatric dermatology for years, authoring publications such as "Lexicon of Pediatric Dermatology" and serving as a former national consultant in the field. In our subsequent conversation, the Professor reminded us of what is most important in skincare: respect for the delicate protective barrier of a child's skin.
Lipid Barrier Mechanism: Why does baby's skin need protection?
Before we move on to specific treatments, we need to understand the challenges a newborn's body faces. A baby's skin is approximately 20-30% thinner than adult skin upon birth. Its most important layer – the lipid barrier (often called the water-lipid barrier) – is not yet fully mature.
How does it work?
Imagine your skin as a wall. Epidermal cells are the bricks, and the lipid barrier (composed of ceramides, fatty acids, and cholesterol) is the mortar that holds them together. In a little human, this "mortar" is very delicate. It serves two key functions:
- Protection against "intruders":Blocks the penetration of allergens, bacteria and irritants from the outside.
- Maintaining moisture:It prevents transepidermal water loss (TEWL). If this barrier is compromised, water escapes from the skin, leading to dryness, itching, and inflammation.
Washing too often with aggressive cleansers washes away these valuable lipids, leaving the skin defenseless. That's why Professor Kaszuba emphasizes: skincare should support the natural barrier, not replace it.
Bathing under the microscope: less is more!
Professor Kaszuba recommends bathing newborns and infants no more than twice a week. Although a daily bath is considered a calming evening ritual in many homes, from a medical perspective, it can be harmful to newborns and infants up to six months of age.
Washing more often can lead to:
- excessive dryness of the epidermis,
- irritations and inflammations,
- weakening of the skin's natural barrier.
Rules for a perfect bath:
- Frequency: Twice a week is enough. On other days, local washing of the diaper area and skin folds is sufficient.
- Water temperature: The ideal temperature is 36–36.5°C. It's best to check it with a thermometer or your elbow – the skin there is sensitive and will quickly tell you if the water is too hot.
- Duration: Maximum 10 minutes. Soaking the skin for longer will soften it and facilitate the rinsing of lipids.
- Drying: This is a crucial moment. Never rub the Human's skin with a towel! It should be applied gently, allowing the cotton to "drink" the moisture. Rubbing causes micro-injuries to the thin epidermis.
- Extras: It is worth using liquid emollients that moisturize the skin while washing.
Moisturizing or Oiling? Learn the Difference
Many parents use these terms interchangeably, but from a medical point of view they are two different activities.
- Moisturizing: We use them on children with healthy skin to improve its condition. Moisturizers contain compounds that bind water to the epidermis.
- Greasing: This is essential for dry and atopic skin. Here, we need ceramide products and special moisturizing agents that rebuild the lipid barrier.
Important tip: Emollients (moisturizing and lubricating preparations) should also be used on non-bathing days. If skin tends to dry out, it's worth repeating the balm up to three times a day.
Dermatological facts and myths
Baby oil, popular for generations, isn't always the best choice. The professor warns: while it gives the illusion of a moisturizing effect, it can actually dry out the deeper layers of the skin. Furthermore, if applied too liberally, it clogs pores, leading to heat rash.
Clothing is equally important. The LUUdzik's skin should only come into contact with natural materials.
- Choose white cotton (dyes in colored clothes may cause allergic reactions).
- Avoid artificial fibers and irritating labels.
- For washing, use only gentle detergents intended for babies.
We often want to give our little ones a whole range of cosmetics (bath bubbles, shampoo, face cream, oil, powder). In pediatric dermatology, the principle of minimalism prevails. The fewer ingredients that come into contact with the skin, the lower the risk of allergies.
Diaper rash and eye hygiene
Diaper rash (DRD) is the most common reason for visits to a pediatric dermatologist. It's a classic example of irritant dermatitis. To avoid it, we must ensure the skin doesn't "macerate" (stay wet for too long). This can be helped by:
- Frequent diaper changes - this is an absolute must.
- Choosing diapers for your baby's weight - too tight may cause abrasions and maceration of the epidermis.
- Thorough cleansing - after each diaper change the skin must be clean and dry.
It's also worth remembering eye hygiene. They don't require soaps or lotions. The professor recommends rinsing them with boiled water (possibly with a gentle addition of chamomile) using a sterile gauze pad. Remember the direction: always from the outer corner to the inner corner.
An appeal to parents: a "human" approach
Professor Kaszuba's most important message is to exercise common sense. Let's not succumb to fads like "Korean baby care" or complicated rituals. A child's skin is an organ that only needs our support, not our help.
Let's also remember the psychological aspect – treating a child as a small human being. Let's avoid stressing them out, nurture their mental well-being, and build a relationship with them – even during daily skincare routines. A calm parent is a calm child, and skin treated with gentleness and moderation will reward you with a healthy appearance for years to come.
