What it is

Why do the underarms and intimate area darken?

The skin of the underarms, groin and intimate area is thin and exposed to friction, moisture and hair removal. Each time it becomes inflamed, it produces more pigment, and over time it looks darker. This is called post-inflammatory hyperpigmentation.

The most common causes

  • Friction from skin or tight clothing.
  • Repeated hair removal with a razor or wax.
  • Deodorants, perfumes or irritating products.
  • Hormonal changes, such as pregnancy.
  • Skin type: olive and brown skin pigments more easily.
  • Insulin resistance (acanthosis nigricans).

Depigmentation works on two fronts: controlling the cause and reducing excess pigment with products and techniques that are safe for sensitive areas.

Which products do we use?

  • Meline® (Innoaesthetics): professional depigmentation, with a version for the intimate area.
  • Dermamelan® Intimate (Mesoestetic): in-office treatment for the external intimate area, inner thighs and groin, with at-home maintenance.
  • Sesderma®: depigmenting products for at-home care.

Is this treatment right for me?

It's for you if…

  • You notice your underarms, groin or external intimate area are darker than the rest of your skin.
  • You've already tried creams or home remedies without results.
  • You want a medical, safe and discreet plan.

It's not the right time if…

  • Your skin is irritated, has wounds or an active infection in the area.
  • You are pregnant or breastfeeding: some depigmenting agents are not used during this stage.
  • You are looking to bleach your skin completely: the goal is to even out the tone.
Areas

Which areas can be treated with depigmentation?

Each area has its own sensitivity. We choose the product and technique according to the skin and the cause.

01

Underarms

The most requested area. Friction, hair removal and some deodorants inflame the skin and darken it over time.

02

Groin and inner thighs

Thigh friction and tight clothing promote darkening. It is treated with products designed for sensitive skin, such as Dermamelan® Intimate or Meline®.

03

External intimate area

Only the external skin, never the mucous membranes. We use products created for this area, such as Meline® Intimate and Dermamelan® Intimate, under medical supervision.

04

Body folds

Neck, folds under the bust or on the abdomen. When the darkening has a velvety texture, insulin resistance should be ruled out.

05

Knees and elbows

Repeated pressure and friction thicken and darken the skin. They improve with gentle exfoliation and moisturizing, in addition to the medical plan.

06

Facial dark spots

If you also have dark spots on your face, the plan is different. See dark spots and melasma.

My approach

Lightening without irritation

In these areas, stronger is not better. An aggressive product irritates the skin, and irritated skin gets darker. That is why we work with appropriate concentrations, in stages and with follow-up.

We also tell you the truth: if the cause is metabolic or hormonal, treating only the skin is not enough. If you also have dark spots on your face, or you are interested in a peel or another body treatment, we bring it all together in a single plan.

Your at-home care

  • Use an alcohol-free, fragrance-free deodorant for the duration of the treatment.
  • Avoid razors and wax while the skin is sensitive, as we advise.
  • Choose cotton clothing that is less tight.
  • Don't use lemon, baking soda or homemade mixtures.

“It's not about bleaching the skin, but about restoring an even, healthy tone.” — Dr. Olga Gómez Montoya

Step by step

What does depigmentation treatment look like, step by step?

Medical assessment

Dr. Gómez reviews the area, your skin type and your habits (hair removal, deodorant, clothing), and looks for the cause of the darkening.

Correcting the cause

We adjust whatever keeps the skin inflamed: hair-removal method, irritating products or friction. If needed, we guide you to look into the metabolic side.

Treatment

Depending on your case: professional in-office depigmentation with Meline® or Dermamelan® and at-home care with Sesderma® depigmenting products, in stages.

Follow-up and maintenance

We review your progress and make adjustments. The lightening lasts better when the factors that caused it are kept in check.

Frequently asked questions

Frequently asked questions about underarm and intimate-area depigmentation

Why do the underarms darken?

The most common causes are friction, repeated hair removal with a razor or wax, some irritating deodorants or perfumes and skin inflammation, which leaves more pigment behind. Skin type, hormonal changes and, in some cases, insulin resistance also play a role. It is very common and has nothing to do with hygiene.

How can I lighten my underarms?

First, remove whatever irritates the skin: change your hair-removal method, use alcohol-free and fragrance-free deodorants and avoid friction. Then, a medical plan with professional in-office depigmentation, such as Meline®, and at-home care with suitable depigmenting products, such as those from Sesderma®. The lightening is progressive.

How can the intimate area be lightened safely?

With products designed for sensitive skin, on the external skin and never on the mucous membranes, and under medical supervision. The intimate area gets irritated easily, and irritation can make it darker. That is why it's not a good idea to use creams or homemade mixtures without an assessment.

What is skin depigmentation?

It is the set of treatments that aim to reduce excess pigment (melanin) in an area of the skin. This is achieved by decreasing pigment production, renewing the surface layer of the skin and controlling the cause. It does not aim to bleach the skin, but to even out the tone.

Do lemon, baking soda or homemade mixtures work?

We don't recommend them. Lemon, baking soda, vinegar or hydrogen peroxide irritate the skin, and irritation produces more pigment. In addition, lemon combined with sun exposure can cause burns and dark spots. Home remedies usually make the problem worse.

Is it safe to use hydroquinone on the underarms or intimate area?

Only with a medical prescription and supervision, at a defined concentration and for a defined period. Prolonged or unsupervised use can cause irritation and even ochronosis, a darkening that is difficult to treat. It is also unwise to use creams without INVIMA registration (INVIMA is Colombia's health products regulator), which may contain undeclared ingredients.

Can dark underarms be a sign of something else?

Sometimes. When the skin of the underarms, neck or body folds looks dark and velvety, it may be acanthosis nigricans, which is associated with insulin resistance. In that case, in addition to treating the skin, it's a good idea to look into the metabolic side with your doctor.

How many sessions are needed, and when will I see a change?

It depends on the product, the cause and your skin type. With Meline®, several sessions a few weeks apart are usually indicated. With Dermamelan® Intimate there is one in-office application followed by a gel you use at home for as long as we tell you. The first changes are noticeable within weeks, and the improvement builds with consistency.

Which products are used: Meline, Dermamelan or Sesderma?

We use Meline® (Innoaesthetics), a professional depigmentation system with a version specifically for the intimate area; Dermamelan® Intimate (Mesoestetic), for the external intimate area, inner thighs and groin, with an in-office phase and an at-home phase; and Sesderma® depigmenting products for daily care. We choose based on your skin, the area and the cause. The darkening can come back if the friction or irritation continues, which is why the plan includes correcting the cause.
