Reduce shaving frequency with Laser Hair Removal

The pursuit of hair-free and smooth underarms has led many individuals to explore various hair removal methods, with shaving being one of the most popular and accessible options. However, a longstanding belief is that shaving can cause underarm darkening, leaving many people wondering if there’s a solution that can address this concern. Laser Hair Removal has emerged as an effective treatment, but does it really solve the myth of shaving darkening your underarm? In this article, we will explore the relationship between shaving and underarm darkening, and how Laser Hair Removal can offer a potential solution to this commonly debated topic.

What Is Underarm Darkening?

Underarm darkening, also known as hyperpigmentation, is a condition characterized by the darkening of the skin in the underarm area. This occurs due to an increase in melanin production, the pigment responsible for skin color. Various factors can contribute to underarm darkening, including hormonal changes, friction from clothing, and certain medical conditions. While shaving has often been linked to this concern, it is important to delve into the root causes to determine if Laser Hair Removal can indeed address this issue.

The Relationship Between Shaving & Underarm Darkening

Shaving itself does not directly cause underarm darkening. However, several factors associated with the shaving process can contribute to the appearance of darker underarms:

Stubble Effect: After shaving, the hair follicles remain just below the skin’s surface, giving the appearance of dark spots or stubble. This can create the illusion of darker underarms, especially in individuals with darker hair or fair skin.

Irritation & Friction: Shaving can cause skin irritation and friction, particularly when done with a dull razor or too frequently. This irritation may lead to temporary redness or darkening of the skin, but it is not a direct cause of long-term hyperpigmentation.

Residual Product Build-up: Shaving can leave behind residual shaving cream or deodorant, which may mix with sweat and dead skin cells, potentially contributing to darkening in the underarm area.

What If You Have Dark Underarms From Shaving?

If you’re dealing with dark underarms because of shaving, Pico Laser can be the solution.

Darkening often occurs due to irritation, inflammation, or pigmentation issues resulting from frequent shaving

Pico Laser treatments can effectively target and break down pigment particles, helping to lighten dark areas and promote a more even skin tone.

The precision and versatility of Pico Laser make it suitable for addressing specific concerns like underarm pigmentation, and the procedure typically involves minimal downtime.

By stimulating collagen production and encouraging skin renewal, Pico Laser not only addresses existing pigmentation but also contributes to overall underarm skin rejuvenation.

Consulting with a skincare professional can provide tailored advice on incorporating Pico Laser into a comprehensive plan to address dark underarms and achieve optimal results.

How Does Underarm Whitening work?

Underarm whitening with Pico Laser involves using advanced laser technology to address pigmentation issues and promote a lighter, more even skin tone.

The Pico Laser emits ultra-short pulses of laser energy in picoseconds, allowing for precise targeting of pigment particles in the skin.

This precision breaks down the melanin responsible for dark pigmentation, effectively lightening the treated area.

Why Shaving Darkens The Underarm?

Shaving itself does not directly cause the underarms to darken. However, several factors associated with shaving can contribute to the appearance of darkened underarms:

Ingrown Hairs

Shaving can sometimes lead to the development of ingrown hairs, where the hair curls back into the skin instead of growing out. Ingrown hairs can cause inflammation and pigmentation changes, leading to dark spots.


The friction caused by shaving against the sensitive skin of the underarms can irritate the skin. Constant friction, especially with a dull razor, may result in darkening over time.


Shaving can cause minor trauma to the skin, and in some cases, this can trigger the production of excess melanin, leading to hyperpigmentation or darkening of the skin.

Improper Technique

Shaving with improper technique or using harsh products can contribute to skin irritation and, subsequently, darkening of the underarms.

How Laser Hair Removal Solves The Shaving Problem?

Laser Hair Removal targets the hair follicles deep within the skin. The laser energy is absorbed by the melanin in the hair follicles, effectively damaging them and inhibiting further hair growth. As a result, it reduces the appearance of dark stubble for a smoother and an even underarm complexion.

Laser Hair Removal also reduces the need for frequent shaving to minimize potential skin irritation and friction. With each laser session, the hair follicles are progressively weakened, resulting in finer and lighter hair regrowth. This reduction in hair density further contributes to a brighter and less darkened underarm appearance.

What Are The Benefits Of Laser Hair Removal?

Lasting Results: Laser hair removal offers long-lasting hair reduction, reducing the need for frequent shaving and the appearance of dark stubble.

Minimizes Skin Irritation: By targeting hair follicles, Laser Hair Removal reduces the risk of skin irritation and friction associated with shaving.

Even Skin Tone: Laser Hair Removal contributes to a more even underarm skin tone by reducing the contrast between the skin and hair.

Improved Confidence: Achieving smoother and hair-free underarms can boost confidence and self-esteem, especially during the warmer months when sleeveless attire is more common.

How Does Pico Laser Eliminate Underarm Pigmentation?

Pico Laser stimulates collagen production and promotes skin renewal, contributing to overall underarm rejuvenation.

The procedure is designed to be precise, minimizing the risk of damage to surrounding tissues and ensuring efficient and effective treatment.

The ultra-short pulses generate pressure that shatters pigment particles into smaller fragments.

These smaller particles are then naturally eliminated by the body’s lymphatic system, leading to a lightening of the treated area.

Multiple sessions may be recommended to achieve optimal results, and patients can typically resume their regular activities with minimal downtime.

It’s essential to consult with a qualified skincare professional to determine the suitability of Pico Laser for underarm whitening based on individual skin concerns and goals.

Will Laser Hair Removal Also Darken The Underarm?

No, Laser Hair Removal will not darken the underarm. On the other hand, it may help reduce skin darkening by eliminating the need for shaving or waxing, which can cause irritation and contribute to hyperpigmentation.

Is Pico Laser Safe For Underarm Whitening?

Pico Laser is a safe treatment for underarm whitening when performed by a qualified and experienced healthcare professional or aesthetic practitioner.

The technology’s precision and targeted approach minimize the risk of adverse effects, making it a safer option compared to some traditional laser treatments.

However, as with any cosmetic procedure, individual responses can vary, and potential side effects may include temporary redness, swelling, or mild discomfort which will go away within a few hours.

It’s crucial to undergo a thorough consultation with a qualified practitioner to assess your skin type, discuss expectations, and determine the most appropriate treatment plan. 


While shaving does not directly cause underarm darkening, it can contribute to the appearance of darker underarms due to temporary factors such as stubble and skin irritation. Laser Hair Removal presents an effective and lasting solution to address this concern for a smoother and even underarm complexion.
