At the birth of your child, his skin is immature, it will take two to three years before performing all its functions. Toiletries, care products, laundry and even clothing ... your little one's fragile skin needs maximum softness.
The advice of our specialist, Dr. Agnès Gougerot, dermatologist, for adapted hygiene.
- At the birth of your child, his skin is immature, it will take two to three years before performing all its functions. The epidermis of the infant is much thinner than that of an adult and therefore much more permeable to external agents. The dermis, situated below, is four times less thick. Sebaceous glands producing sebum (oily secretion on the surface of the skin) and sweat glands (releasing sweat) do not yet function fully. The surface hydrolipidic film, composed of water and fat, does not play its role of barrier, the skin of your child is very fragile and sensitive to the aggressions.
1. Skin imperfections are common in a baby
- The sebaceous glands are active during fetal life. They will only become fully mature as your child grows. But, at birth, under the influence of maternal hormones, they often secrete an excess of sebum. Consequence: the skin of your newborn is sometimes very fat with for example on his face, small white grains (grain of milium) made of sebum.
- Similarly, sweat retention can create small water blisters called "sundania" or "bourbouille". A seborrheic dermatitis may be manifested by redness on the face or skull, by the formation of milk crusts. Finally, the acne of the infant exists in the form of small red buttons, even of a true acne identical to that of the teenager.
- Rest assured ! These imperfections will disappear a few weeks after the birth of your baby.
2. His skin is very sensitive to aggression
- When the changes are insufficient, urine and stool weaken the skin under the diaper. Similarly, detergents (soaps and other cleaners) can be particularly aggressive associated with prolonged contact with water, for example in a bath too long, or when the skin barrier is impaired by a dermatosis, such as atopic dermatitis or dermatitis. dermatitis of the buttocks. The friction of the skin as for it favors a loss of water of the epidermis: its hydration decreases and the lipid layer is modified. Your baby's skin then becomes very dry and peels.
- Be aware that the bacterial flora that colonizes the skin from the first days of life is essential to its good balance (ecosystem) and can be disrupted by inappropriate hygiene measures.
3. In an infant, the toxic risk of a product is higher
- The ratio of skin surface area to weight is much greater in infants than in adults. The concentration of a product in the tissues will be stronger in the baby for the same surface of application. The same cream for young and old will have very different consequences.
- In addition, your baby is more sensitive to the risk of intoxication due to the immaturity of his liver, his kidneys and a great weakness of the barrier between the blood and the brain.
- To remember: the most toxic components for his skin are alcohol and essential oils until the age of 3 years.
