Our skin tone is more than just a cosmetic feature; it’s a direct reflection of a vital pigment called melanin. These pigments are produced by special cells called melanocytes. Melanin plays a significant role in determining the colour of your skin. In addition, it also provides protection against the UV rays of the sun, followed by influencing pigmentation disorder. In this blog we will understand the role of melanin in skin pigmentation and also explore effective pigmentation treatment in Gurgaon. Stay tuned!

Understanding Melanin

Melanin is a natural pigment found in the skin, hair, and eyes of humans and animals. It’s produced in the basal layer of the epidermis by melanocytes. The amount and type of melanin your body produces determine your skin tone and colour response to sunlight.

Moreover, melanin also provides protection from the sun’s harmful rays by absorbing them, reducing DNA damage and the risk of skin cancers.

Types of Melanin

There are three main types of melanin, each contributing to different pigmentation features:

  • Eumelanin

  1. Most common type

  2. Provides brown to black pigment

  3. Found in darker skin tones and black/brown hair

  4. Offers strong UV protection

     

     

  • Pheomelanin

  1. Produces yellow to reddish hues

  2. Found in lighter skin, red hair, and lips

  3. Less effective at blocking UV rays
  • Neuromelanin

  1. Found in the brain, not related to skin color

  2. Plays a role in neurological functions and is studied in neurodegenerative diseases
     

Relation between Melanin and Skin Pigmentation

The amount, distribution, and type of melanin are responsible for natural skin tones. However, certain internal and external factors can disturb melanin production, leading to pigmentation disorders such as:

  1. Hyperpigmentation: Overproduction of melanin causing dark patches

  2. Hypopigmentation: Reduced melanin leading to light or white patches

  3. Depigmentation: Complete loss of melanin in certain areas
     

Types of Pigmentation 

Here are different types of pigmentation mentioned below: 

  • Melasma

  1. Characterized by brown or gray-brown patches on the face

  2. Often triggered by sun exposure, hormones (pregnancy or birth control), and genetics.
     
  • Sunspots (Solar Lentigines)

  1. Caused by prolonged sun exposure

  2. Appear as flat brown spots, commonly on the face, hands, and shoulders
     

     

  • Post-Inflammatory Hyperpigmentation (PIH)

  1. Dark spots that develop after skin inflammation or injury (acne, burns, eczema)

  • Freckles (Ephelides)

  1. Small, concentrated spots of melanin

  2. Genetic and exacerbated by sun exposure
     
  • Vitiligo

  1. An autoimmune disorder causing loss of melanocytes, leading to white patches
     

Factors Affecting Melanin Production

Here are factors affecting melanin production: 

  1. Genetics: Your genes dictate your baseline melanin levels.

  2. Hormonal changes: Can trigger conditions like melasma.

  3. Sun exposure: Stimulates melanocytes to produce more melanin as a defense mechanism.

  4. Medications: Certain drugs may cause pigmentation as a side effect.

  5. Inflammation or trauma: Injuries can lead to post-inflammatory pigmentation.
     

Treatment Options for Pigmentation Conditions

Here are effective treatment options for pigmentation conditions

  • Laser Therapy: Lasers break down melanin clusters for the body to absorb and eliminate. Examples of such lasers are as follows: 

  1. Q-switched lasers

  2. Pico lasers

  3. Fraxel
     
  • Microneedling: Creates micro-injuries in the skin to stimulate collagen and even out pigmentation. Microneedling

  1. Can be combined with serums or PRP for better results

  2. Helps treat acne scars and PIH
     
  • Oral Supplements: Examples of oral supplements for treating pigmentation issues are as follows:
