DEFINITION OF HYPERPIGMENTATION 

Hyperpigmentation is the darkening of an area of the skin caused by increased melanin production. Melanin is the pigment that gives skin its colour.

TYPES OF HYPERPIGMENTATION

There are different types of hyperpigmentation.

  Dark spots: These are patches that develop after an inflammatory skin condition, such as acne, eczema, or psoriasis. It occurs when the skin heals from the inflammation.

Melasma: Often referred to as "the mask of pregnancy, melasma causes brown to gray-brown patches, usually on the face. It is commonly triggered by hormonal changes, such as pregnancy or birth control pills, and can be exacerbated by sun exposure.

Sunspots : Also known as age spots, these are caused by prolonged sun exposure. They typically appear on sun-exposed areas like the face, hands, shoulders, and arms.

Freckles :They are Small, flat, brown spots that appear on sun-exposed skin, they can darken with sun exposure and often fade in the winter months.

 CAUSES

Sun exposure: Prolong exposure to UV radiation without sunscreen can lead to dark spots.

Hormonal changes: Changes in hormone levels during different life stages  e.g. puberty, pregnancy.

Skin injury:  Picking at a pimples  resulting in a blemish scar.

Inflammation: Acne or eczema flare-ups leading to dark Spots. 

HOW TO PREVENT HYPERPIGMENTATION 

 Preventing hyperpigmentation involves protecting the skin from factors that can trigger excessive melanin production.

Here are some effective strategies:

Sun Protection: Use a broad-spectrum sunscreen with at least SPF 30 daily, even on cloudy days. Reapply every two hours and after swimming or sweating.

 Protective Clothing: Wear hats, sunglasses, and long-sleeved clothing to shield skin from the sun.

 Seek Shade: Avoid direct sun exposure, especially  when UV rays are strongest.

Skincare Routine:

   Gentle Cleansing: Use gentle cleansers and avoid harsh scrubbing to prevent skin irritation.

   Moisturize: Keep the skin hydrated to reduce irritation.

   Inflammation: Treat skin conditions like acne promptly to prevent post-inflammatory hyperpigmentation.

   Medications: Consult with your doctor if you suspect certain medications are causing hyperpigmentation.

Healthy Lifestyle:

   Diet:  Eat a balanced diet rich in antioxidants, which can help protect the skin from damage.

   Hydration:  Drink plenty of water to keep skin healthy.

Sun Protection: Continuously use sunscreen to prevent further pigmentation and protect treated areas.

Avoid Picking Skin: Prevents post-inflammatory hyperpigmentation.

TREATMENT

Treating hyperpigmentation

 Here are some effective approaches:

1. Vitamin C:  An antioxidant that helps brighten skin and reduce pigmentation.

2. Niacinamide:  Reduces melanin transfer and has anti-inflammatory properties.

3. Azelaic Acid:  Effective for both acne and hyperpigmentation, it helps reduce melanin production.

4. Kojic Acid: Inhibits melanin production and has antioxidant properties.

5.Chemical Peels: Use acids (like glycolic, salicylic, or lactic acid) to exfoliate the skin and promote cell turnover.

6. Laser Therapy: Various laser treatments target and break down melanin, improving pigmentation.

7. Microdermabrasion: Exfoliates the skin’s surface to improve skin texture and tone.

8 .Micro needling: Stimulates collagen production and can help with hyperpigmentation.
