Dark underarm spots are an aesthetic problem that affects both men and women. They can be a source of discomfort, especially in the summer months when we wear more exposed clothing. Many people wonder where these discolourations come from and whether they are related to depilation. In this article, we will look at the causes of dark underarm spots, the link between depilation and hyperpigmentation and how to prevent and treat them.

What are dark underarm spots?

Underarm dark spots, also known as hyperpigmentation, is a condition where the skin in this area becomes darker than the rest of the body. Hyperpigmentation can range from light brown to almost black, and is usually caused by excessive production of melanin - the pigment responsible for skin colour.

The causes of dark underarm spots are varied and can be related to both external and internal factors.

Main causes of spots

  • Skin irritation

Underarm skin is particularly delicate and regular shaving or depilation can irritate it. Shaving with a razor often damages the surface of the epidermis, leading to micro-injuries that can cause inflammation. As a result of this process, the skin produces more melanin, leading to darkening.

  • Reactions to cosmetics

Some deodorants, antiperspirants or depilation creams can contain ingredients that irritate the skin and cause discolouration. Alcohol, fragrances and chemicals in cosmetics can contribute to dark spots, especially if used on irritated skin after depilation.

  • Post-inflammatory hyperpigmentation (PIH)

After depilation or shaving, if the skin is irritated, inflammation can occur, which causes what is known as post-inflammatory hyperpigmentation. This is a defensive reaction of the skin in which cells produce more melanin in response to inflammation. The result is darker patches on the skin.

  • Genetic and hormonal factors

Dark spots can be the result of genetics or hormonal changes, such as during pregnancy or use of hormonal contraception. Hormones can affect the production of melanin, leading to darkening of the skin in certain areas, including the underarms.

How to prevent dark underarm spots?

After any depilation, it is a good idea to use soothing alcohol-free cosmetics to minimise irritation. Products with aloe vera, panthenol or allantoin help to soothe the skin and reduce the risk of inflammation. Avoid deodorants with alcohol immediately after depilation to avoid irritating freshly shaved skin. Regular exfoliation of dead skin helps avoid clogged pores and ingrown hairs, which can lead to irritation and discolouration. It's a good idea to exfoliate underarms 1-2 times a week with gentle products to avoid additional irritation.Choose antiperspirants and deodorants that are free of alcohol, parabens and artificial fragrances. Natural products based on mild ingredients can help minimise irritation and therefore reduce the risk of hyperpigmentation.

How to treat underarm hyperpigmentation?

There are special skin-lightening creams on the market that can help to combat dark underarm spots. These preparations often contain ingredients such as:

  • kojic acid,
  • vitamin C,
  • azelaic acid.

These substances inhibit melanin production and help to lighten discolouration. However, it is always advisable to consult a dermatologist before starting to use such preparations.

If hyperpigmentation is stubborn, you may want to consider professional treatments at beauty salons such as chemical peels, microdermabrasion or laser hyperpigmentation removal. These treatments work deeper into the skin to help reduce existing dark spots and even out skin tone.
