BACKGROUND
At birth, the neonates’ skin is structurally and functionally immature compared to adult skin.1 Neonates and infants exhibit distinct anatomical and functional skin properties making it susceptible to skin barrier disruption.1-3 Infant skin functionally is still developing as indicated by elevated trans-epidermal water loss (TEWL), skin surface pH and desquamation.2-5 Several mechanisms may play a role in the slightly alkaline skin pH at birth; the most relevant could be the exposure to the alkaline amniotic fluid during the preborn life.4,5
The process of skin acidification, which takes place during the first years after birth, plays a vital role in barrier maturation and the activation of enzymes involved in the extracellular processing of stratum corneum lipids.4,5 The definition of sensitive skin is normal-appearing, not atopic skin, which overreacts to various factors that would not cause a reaction in healthy skin.2 Neonatal and infant skin is more fragile, at risk of heat loss, has elevated thermal conductance, and is more susceptible to infections and chemical and thermal damage.1-5 During the first years after birth, the infant skin is more permeable to topical agents, which may induce systemic toxicity.3 The neonatal and infant skin, therefore, requires particular caution with topical skincare regimens.1-3
PH-neutral or mildly acidic cleansers have benefits for neonates and infants.1-3
Taking into consideration the maturation process of neonatal and infant skin, the application of moisturizers and cleansers
