The human skin is the most exposed organ to the external environment and represents the first line of defense against external chemical and microbial threats. It harbors a microbial habitat that is person-specific and varies considerably across the body surface. Recent findings suggested an association between the use of antiperspirants or make-up and skin microbiota composition.
Use of skin personal care products on a regular basis is nearly ubiquitous, but their effects on molecular and microbial diversity of the skin are unknown. This is important to always use skin care products that are tested and trusted.
