DermaProof Asia presents the rationale behind the rigorous evaluation of the cosmetic or aesthetic treatments for the axilla, focusing on in vivo test methods, which are the most suitable options in the perspective of gathering evidence to support claims
The skin of the axilla (underarm or armpit area) has several distinctive characteristics that differentiate it from other body sites. These specificities are important to consider in the context of skin care, deodorants, antiperspirants, and overall hygiene.
Compared to other parts of the body, some of the key features of axillary skin are thinner epidermis and dermis (which makes it more sensitive and susceptible to irritation), its high density of sweat glands (eccrine, apocrine and apoeccrine, which are hybrid glands developing during puberty). The axilla is a hair-bearing area in both men and women where skin is often folded.
The combination of skin folds, nutrient-rich sweat gland secretions and hairs creates a very favourable environment for bacterial growth leading to a distinct microbiome that includes a higher concentration of bacteria, especially Corynebacterium and Staphylococcus species.
