Health of the skin is one of the major preoccupations related to the use of cosmetic care products. In the case of deodorants, the concept of naturality has received significant attention over the past several years.

Controversies surrounding certain ingredients, in particular those used for their anti-odor action, have been a factor in this increased demand for more natural formulas with no negative effects on the skin.

Up to now, the prevention of unpleasant odors from perspiration has relied on three principal strategies ^[2]:
- Antiperspirant strategy preventing sweat from being released onto the surface of the skin. This often requires the use of aluminum salts that are controversial ingredients ^[3].
- Antiseptic action using broad spectrum antimicrobial agents. This strategy adversely affects the equilibrium of the skin’s microbiota and the ingredients used may be skin irritants, allergens or suspected of being endocrine disruptors ^[4].
- Perfuming action that masks unpleasant perspiration odors. The alcohol content of the products used in this strategy may cause skin irritation.

Recognized by the scientific community and validated by consumers, the microbiota remains one driver in the innovation of beauty products. This concept provides a natural and effective strategy for minimizing unpleasant odors by regulating certain bacterial populations.

Even though the surge of more natural formulas has enabled the class of these products to experience a genuine turning point, it is now the concept of skinification that has revitalized the multifunctionality of products and has ushered in a new era of innovations.

In addition to odors, perspiration also induces skin sensitivity that is accentuated by the fact that underarm skin is thin. In addition, epilation techniques, friction, certain hygiene products or heat considerably weaken the barrier function of this delicate skin zone and contribute to the appearance of irritations ^[7].

Irritations are therefore an additional source of discomfort for the underarms and explain the need to develop specialized care products for this skin zone.

Obtained from meadowsweet and tested on a panel of both sexes, DEOLYA^® significantly reduces unpleasant underarm odors as of the first used and over the long term.

This active ingredient targets S. hominis, while respecting microbial diversity of this skin zone. In addition, when tested for one month on volunteers with axillary sensitivity, it was found that DEOLYA^® strengthens the skin’s barrier function and reduces the frequency of sensations of irritations.
