Underarms and groin: how to lighten sensitive areas?
The sensitive area lightener addresses a growing demand in body care: reducing hyperpigmentation of the underarms and groin without irritating the skin.
Constant friction, frequent hair removal, and the use of chemical deodorants stimulate melanin and darken these areas. Cobiosa offers specific active ingredients with documented efficacy to address this problem.

Why do sensitive areas of the body darken?
Hyperpigmentation in the underarms and groin has multiple causes. Frequent hair removal and shaving create micro-lesions and irritation that stimulate melanin production. Constant friction from clothing acts as a mechanical factor in pigmentation. The chemicals in deodorants and antiperspirants irritate the skin, and a lack of exfoliation leads to an accumulation of pigmented dead skin cells.
Melanin and friction: the two main factors
Melanin is the pigment that gives skin its color and is produced in excess as a defensive response to any aggression. In areas of high friction, such as the armpits and groin, mechanical stimulation acts as a chronic trigger for hyperpigmentation. This is compounded by the heat and humidity typical of these areas, which intensify the pigmentary response.
Inadequate exfoliation: accumulation of dead cells
Cell renewal in skin folds is slower than in other areas of the body, which promotes the accumulation of pigmented dead cells that visibly darken the skin tone. Regular, gentle exfoliation removes these cells and accelerates renewal, revealing a more even tone and improving skin texture in these areas.
Lightening agents for underarms and groin
Cobiosa has two active ingredients specifically indicated for the treatment of hyperpigmentation in sensitive areas: Hentowhite AF, based on Hexylresorcinol derivatives, which offers excellent results in reducing spots and lightening the skin without irritating effects; and Pore Reductyl NT, an active ingredient of Fomes officinalis with a natural antiperspirant effect.
Hentowhite AF: brightening without irritation
Hentowhite AF is an active ingredient based on Hexylresorcinol derivatives, specifically formulated for sensitive areas. It acts on melanin production to reduce dark spots and even out skin tone in the underarms and groin area without causing the irritation typical of other lightening agents. Its tolerance profile makes it suitable for reactive skin and prolonged use.
Pore Reductyl NT: natural antiperspirant
Pore Reductyl NT is an active derived from Fomes officinalis that, thanks to its astringent activity, exerts a natural antiperspirant effect without blocking sweat glands. It also provides a tightening and moisturising effect, contributing to minimising pores and absorbing excess secretion in high-humidity areas.

Formulation: effective formats for sensitive areas
The most effective applications for treating underarms and groin are aqueous gel, silky cream, and spray toner. Each format offers a different sensory experience and an application profile adapted to different usage times and consumer types, from daily deodorant to intensive nighttime treatment.
Active Anti-Perspirant: Dual-action deodorant gel
The active deodorant gel combines Pore Reductyl NT and Hentowhite AF at 5% each in a light, water-based formula. It offers dual action: on one hand, it minimizes pores and absorbs excess oil; on the other, it reduces dark spots and lightens underarm skin, promoting a healthy, even tone without causing irritation or clogging sweat glands.
Creamy Feeling and Freshly Whitening Toner: complementary options
Creamy Feeling is a silky-textured cream deodorant specially formulated for sensitive skin, featuring the same active combination of Pore Reductyl NT and Hentowhite AF in a gentle emulsion base. Freshly Whitening Toner is a refreshing toning spray that provides a unique skincare experience with a brightening and luminous effect.
