Ideally, your underarms should be of the same colour as the rest of the body but underarm skin is very sensitive and can have multiple problems such as rashes, infection, acne or ingrown hair. The most common complaint raised by both men and women is hyperpigmentation of the area and many women suffer from embarrassment as their armpits are several shades darker and restrict them from wearing sleeveless garments. It is frustrating for many and also affects their self-confidence. The colour of the skin is determined by a pigment called ‘melanin’. When this multiplies, it leads to darker skin colouration. Underarms is an area which is mostly neglected and not taken care of well.
