Is underarm pigmentation after shaving normal at age 19?

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

First of all, please do not worry, underarm pigmentation at 19 years of age is quite common, and it is a good sign that you noticed the changes early and are seeking proper guidance.

Based on what you have described, darkening of the skin with a slightly thick, velvety texture, the most likely cause is acanthosis nigricans (this is a skin condition where areas like the underarms become darker, thicker, and velvety. It happens when skin cells grow faster than normal), along with post-inflammatory hyperpigmentation (darkening of the skin after repeated irritation or injury, such as shaving) caused by long-term shaving.

Since you have been shaving your underarms from a very young age, the skin has been exposed to repeated friction and tiny, unnoticed cuts. Because of this, the skin becomes irritated again and again. As a response, pigment-producing cells called melanocytes start making extra color, which slowly leads to darkening over time.

The velvety or slightly thick feel of your underarm skin is an important clue. This tells us that the pigmentation is not only on the surface but also involves deeper layers of the skin. That is why simple creams or exfoliating products often do not give quick or dramatic results.

In many teenage girls, this type of pigmentation is linked to insulin resistance. Insulin is a hormone that controls blood sugar, and insulin resistance means the body needs more insulin than usual.

During adolescence, hormonal changes naturally occur. As a result, insulin levels may increase, even if body weight appears normal. This increased insulin stimulates skin cells, leading to thickening and darkening in areas like the underarms, neck, and inner thighs.

Glycolic acid and other exfoliating agents work mainly on the top layer of the skin. However, when the root cause is internal, such as hormonal or insulin-related changes, surface treatments alone are often not enough; this explains why you did not see much improvement earlier.

Ubik cutis contains Lactic acid (gentle exfoliation) and Retinol (skin renewal). Because of this combination, you noticed slight lightning. This is encouraging, as it shows the pigmentation is reversible, but improvement is slow because underarm skin is sensitive.

While creams help, they cannot work alone. Unless friction, shaving habits, and possible metabolic factors are addressed, results will remain limited. Also, Lactic acid alone is not enough; a combination of active ingredients works better.

At this stage, gentle care and prevention of further damage are most important.

1. Avoid frequent shaving; trimming is safer.

2. Avoid scrubbing, loofahs, lemon, baking soda, or harsh acids, as these worsen pigmentation.

3. Use a mild cleanser and regular moisturizer to reduce friction.

I would advise basic screening for insulin resistance, such as:

1. Fasting blood sugar.

2. HbA1c or glycated hemoglobin (average blood sugar over three months).

Especially if you notice similar darkening on the neck or thighs, or if there is a family history of diabetes or PCOS (polycystic ovary disease). If overweight, gradual weight reduction is also important.

Along with treatment, simple steps like a balanced diet, regular physical activity, and proper sleep can slowly improve skin changes over time.

The treatment plan (combination approach) for you is:

1. G-Peel 6 cream (Glycolic acid six percent), twice weekly at night.

2. Ubik Cutis on the remaining nights.

3. Kozicare cream (Kojic acid, Glutathione, mulberry extract, Arbutin, Liquorice extract, Niacinamide, and Allantoin) daily in the evening.

With consistency, visible improvement usually appears in eight to 12 weeks. So, patience and regular care are key.

I hope this helps.
