Hyperpigmentation Bikini Line Treatment 101: Read Me First!

You’ll love these easy-to-make, easy-to-apply tips if you are looking for hyperpigmentation bikini line treatment!

If you, like me, have a high level of melanin and are sensitive to certain stimuli (such as waxing and razors), you may have noticed hyperpigmentation in the bikini area. 

Another problem that comes in hand with hyperpigmentation is when we tend to have ingrown hairs, causing redness and painful (pus-filled) bumps – aka folliculitis.

I certainly feel embarrassed when wearing a bathing suit if my bikini area is darker and full of Lil bumps. What about you?

If you suffer from it, it is crucial to find out what causes this coloration and how to treat and lighten these regions.

Keep on reading that I will share some methods, including a tested method that my dermatologist recommended.

What causes darkening in the groin and armpit?

Ingrown and darkening happen for similar reasons: waxing, razors, and depilatory creams.

In my case, for example, waxing and creams are fine, but I cannot ever dare to use razors again!

The body understands the action as aggression and produces more melanin in the region, making the skin thicker.

This reaction is a form of defense for the body, as an inflammatory process begins soon after the skin is traumatized, which can lead to post-inflammatory hyperchromia, which is the darkening of the region. 

Other actions darken the area, such as exposure to the sun, allergies, irritation caused by cosmetics, diaper rash, friction, ringworm, and homemade applications to lighten the skin.

Because they are more sensitive regions, spots and darkening appear even more in darker skin, which has more significant production and amounts of melanin in the body. 

These pigments vary from brownish to black.

What Triggers Hyperpigmentation?

In general, the spots and groin appear due to stimuli that trigger an inflammatory process in the region.

This process increases the production of melanin, which concentrates and forms dark spots.

The most common stimuli are:

Tight clothes

Tight clothing causes the fabric to be too close to the skin, not allowing it to “breathe.” 

The result is more moisture in the region, which contributes to the appearance of stains.

Hormonal changes

These changes cause hormonal “imbalance” and consequently increase the production of melanin, which will pigmentation the skin. 

They are more common during pregnancy, menopause, and in people with diabetes.

If you suffer from hyperpigmentation, then it is important to look for a dermatologist sooner or later to find out if your problem originates from hormonal problems.

Friction between the legs

When walking, if the legs are too close together, it can cause friction, which, among other things, contributes to the formation of the inflammatory process responsible for skin hyperpigmentation.

Shave with razor

Shaving with a razor is one of the main causes of hyperpigmentation in the bikini line. 

The use of razors for hair removal is also a trigger for pigments and folliculitis.

This is because the movement made with the blade causes skin irritation, facilitating the appearance of stains, especially in regions where the skin is thinner or sensitive, such as the groin.

Allergic reactions

Moisturizing creams, depilatory lotions, and other products can cause allergic reactions that irritate the skin, increasing the inflammatory process and, as a result, blemishes.

How To Lighten spots on the groin: My Experience

When I went to the dermatologist, I found out my problem was not hormonal, but it had to do only with my hair removal habits.

I used a razor, and I noticed with the time that not only my bikini line was darker, underarms.

Folliculitis was another problem that occurred on my bikini line and legs. I have Lil bumps all over the area, which was not nice looking.

I had to stop using the razor but was able to use wax. Nonetheless, my doctor told me to use an electric hair removal machine and hydrate the area with Physiogel cream as my primary waxing method.

If you don’t have Physiogel, you can use Cerave or Cetaphil or Avene moisturizing cream as well I have tried them, and it worked.

Cerave vs Cetaphil

Note that these creams won’t make hyperpigmentation go away instead, they will treat the area and help you improve the appearance of folliculitis.

After treating the irritated area, you may apply a solution that will clear the area.

For more potent treatments, you will need to ask the doctor as only they will know what will help you without causing harm.

However, some safe bikini lighting creams can help in cases that are not so serious.

In some cases, just treating the area with moisturizing will restore your skin and look lighter over time. It was my case in the bikini areas.

But it depends from person to person.

In most cases, once you identify what is causing hyperpigmentation and irritation, you should never repeat these practices; otherwise, the problem will come back.

Note: Never forget to moisturize the area every time you remove your hair.

My Bikini Line Hyperpigmentation Treatment: The Results

After a week, I was amazed at how it worked so well for me, as the spots, redness, and irritations started to fade away, and the area started to gradually get back to normal.

I believe you can try this method because it won’t cause you any harm, but if the symptoms persist, you will need to look for personalized doctor advice.

The dermatologist will evaluate the possible causes of the spots to define the most appropriate therapy for each case. 

Based on the diagnosis and assessment of the patient’s life, the following treatments can be indicated:

Creams, ointments, and serums

It is the first solution adopted in most cases because it is less invasive, easy to apply, and with satisfactory results in the first weeks of use. 

The dermatologist must generally indicate the solutions according to the spots’ and the patient’s characteristics.

The composition of the creams varies; however, the most used ones have in their formation drugs such as Vitamin C, kojic acid, tretinoin, and hydroquinone. 

They have commonly used bleaches for the depigmentation of spots such as melasma, age spots, and acanthosis nigricans, among others caused by the accumulation of melanin.

These solutions should be applied directly to the spots as the dermatologist recommends. 

You can usually see results within 2 to 4 weeks, but treatment can last up to 8 weeks.


Peeling is divided into chemical and physical; the principle is the same in both: to promote cell renewal in the area and its whitening.

Chemical peeling uses an acidic solution, usually kojic, lactic, glycolic, salicylic, trichloroacetic acid, and jessner’s solution. 

The choice will depend on the degree of pigmentation, the skin’s natural color, and your body’s acceptance.

The acid is applied to the pigmented region, acts for a few minutes, and is removed to promote skin exfoliation. 

In a few days, a new layer of skin appears. The most significant advantage is that the skin becomes more vibrant, with a better tone and shine, as the peeling also promotes the formation of new collagen and elastin.

Physical peeling uses some equipment to exfoliate the skin and promote cell renewal. 

It is commonly called crystal peeling or diamond peeling because of the tip that performs the exfoliation.

Hyperpigmentation Bikini Line Laser Treatment

The hyperpigmentation bikini line laser treatment breaks down the pigmented cells, which are eliminated by the lymphatic system, without harming the patient. 

It is a painless procedure that stimulates cell renewal; in this way, a new layer of skin “grows” without the pigment.

The technique uses beams of light in ultra-fast pulses aimed only at melanin-producing cells, so even with the intensity, it does not attack the surrounding tissue nor cause discomfort.

There are different types of lasers—the most common aesthetic. The choice will depend on the type of stain, its severity, and the patient’s natural skin tone.

The session is relatively quick, but four or more sessions are needed to reduce the spots noticeably. The side effects are minimal.

However, there are restrictions for pregnant women, lactating women, and people with some type of inflammation in the region.


Microneedling is a technique in which small holes are made in the region with a specific device, injecting drugs that act directly on the stains, such as vitamin C, A, and other depigmenting agents.

The procedure does not cause any discomfort and stimulates the formation of collagen and elastin, improving the appearance of the skin.

Homemade stain removal solutions

As mentioned at the beginning of the text, some solutions, instead of lightening the spots, contribute to making them stronger. 

This is the case with acidic substances such as lemon, which, when misused, can cause stains.

Here is a homemade recipe for an exfoliating scrub suitable for the bikini area, which helps to lighten the region and prevent the appearance of ingrown hairs.

This little mixture helps remove dead cells, facilitating skin regeneration and favoring treatments to whiten the groin, leaving the region with smooth, soft, and hydrated skin.

You only need two ingredients:

  • One tablespoon of brown sugar
  • 1 tablespoon almond oil or extra virgin olive oil
  • Mix the two ingredients in a container and take advantage of bath time to apply the mixture to your crotch—massage with gentle movements for 3 minutes to obtain the exfoliating effect.

A tip: don’t put too much pressure when doing the massage so you don’t end up irritating the skin in the region, which is sensitive.

Make a regular exfoliation with gentle movements.

Repeat this ritual at most twice a week, as it has an abrasive action and can end up hurting the skin if done in excess.

Also, always take care to exfoliate at least four days after epilation so as not to cause any irritation to skin that is already sensitized by the blade or wax.

Tricks to make your recipe even better

If your skin is oily, you can replace sugar with honey, which has anti-inflammatory, astringent, and antimicrobial action, helping the skin to fight the emergence of painful pimples in the groin.

You can replace the sugar with cornmeal for sensitive skin, as the grains are softer and won’t hurt your skin.

If possible, use a vegetable loofah to cleanse the area and rinse with cold water, which helps to soothe the skin.

Reminder: To avoid blemishes and ingrown hairs, it’s also essential to avoid wearing tight-fitting panties, as they irritate the groin and can even reduce blood flow in that area.

Finally, remember to avoid the sun right after waxing, as this habit can cause stains on the skin that is already sensitized.

How to prevent groin and armpit spots?

If you’ve already lightened the area and don’t want the spots to return or want to prevent them, there are many simple measures for that:

  • Keep the area airy, which also prevents the formation of folliculitis;
  • Try to reduce measurements and lose weight to avoid friction;
  • Use groin oil to reduce chafing, including diaper rash;
  • Use moisturizing creams to prevent inflammation;
  • Avoid shaving with a razor.
  • Avoid wearing tight pants and underwear;
  • Keep the area dry after bathing;

With these measures, it is possible to prevent new stains but get a medical follow-up to prevent hormonal dysfunction.

See a dermatologist whenever necessary.

 The need to whiten the groin and armpits may be aesthetic; however, having good self-esteem and self-confidence is essential to maintaining the quality of life.
