Dark marks and discoloration under the arms can be a common concern for women with melanin-rich skin. These dark spots can make you feel self-conscious, but their are ways to diminish their appearance. In this guide, we’ll walk you through how to identify dark spots and how to treat them effectively. We’ll also look at powerful ingredients like retinol, niacinamide, and ceramides, and explain how these ingredients help to give you smooth, even-toned underarms.

Understand dark spots under your arms

Dark spots under the arms, also known as hyperpigmentation, can pop for a number of reasons. It’s important to understand what causes these dark spots to treat them effectively. Here are some common causes:

1. Friction

When your skin experiences repeated friction—like from tight clothing or frequent shaving—it can become irritated. This irritation causes your skin to produce more melanin, the pigment responsible for skin color, leading to dark patches known as post-inflammatory hyperpigmentation (PIH). When you have melanin-rich skin, you are more prone to PIH because your skin naturally contains more melanin.¹

2. Deodorants and antiperspirants

Some deodorants and antiperspirants contain harsh chemicals that can irritate the skin, leading to discoloration. Switching to gentler, more natural deodorants can help.

3. Hormonal changes

Hormonal changes during pregnancy and menopause can lead to darkening of the underarm skin. During pregnancy, increased levels of hormones like estrogen and progesterone can stimulate melanin production, causing areas such as the underarms to darken. Similarly, hormonal fluctuations during menopause can disrupt melanin regulation, leading to uneven skin pigmentation.

4. Medical conditions

Certain medical conditions, like acanthosis nigricans, can cause darkening of the skin in areas like the underarms. Acanthosis nigricans is often linked to health issues such as insulin resistance, or hormonal disorders. In rare cases, it can signal more serious conditions, so it's important to consult a healthcare provider if you notice these changes.²

How to treat dark spots under your arms

Now that we understand the causes, let’s dive into how to treat these dark spots. Here’s a step-by-step guide to help you achieve smooth, even-toned underarms:

Step 1: Exfoliate regularly

Exfoliating helps remove dead skin cells and can prevent the buildup that leads to dark spots. Use a gentle exfoliator with natural ingredients like shea butter or coconut oil to avoid further irritation.

Step 2: Moisturize daily

Keeping your underarms moisturized can help reduce friction and irritation. Look for moisturizers with hydrating ingredients like shea butter, glycerin and natural oils like Raw Shea Butter Hydrating Body Lotion.

Step 3: Use targeted treatments

Incorporate products that contain ingredients known for their skin-brightening properties. SheaMoisture deodorants with retinol, niacinamide, and ceramides can be particularly effective.
