Hyperpigmentation Treatment, Types & Causes | By Dermatologist

All organisms, from simple invertebrates to complex human beings, exist in different colors and patterns, which arise from the unique distribution of pigments throughout the body

Pigmentation is highly heritable, being regulated by genetic, environmental, and endocrine factors that modulate the amount, type, and distribution of melanin in the skin, hair, and eyes.

We consider endocrine factors that induce temporary pigmentation (e.g., during pregnancy) or permanent (e.g., during aging) changes in skin color

environmental factors (e.g., UV), certain drugs, and chemical compounds

We will broadly be talking about Hyperpigmentation

Hyperpigmentation is excessive Pigmentation of the skin

 Hyperpigmentation is of two types

1. Epidermal (superficial)

2. Dermal (Deep)

Conditions which fall under Epidermal are

   Tanning ( immediate & delayed )

   Pigmentary Demarcation lines (PDL)

   Freckles

   Melasma (Epidermal)

   Post-inflammatory hyperpigmentation

Conditions which fall under Dermal are

   Melasma ( Dermal )

   Nevus of Ota

   Nevus of Ito

 Post-inflammatory hyperpigmentation (PIH) is more common in darkly pigmented individuals

• PIH can occur at any age, group or gender

• This form of hyperpigmentation occurs more in areas that have sustained physical trauma such as Acne Vulgaris or eczema

• Can also be mechanical or chemical in nature as might occur following a traumatic cut or chemical burn

• PIH May persists for months to years

• PIH May appear as macular or patches depending upon the insult may be well localized or extensive

• Always important to differentiate whether the pigmentation is Epidermal or dermal which can be done via WOOD LIGHT (woods lamp)

• Under Woods lamp evaluation when pigmentation is present in the epidermis (superficial) the contrast between the normal & hyperpigmented skin is enhanced & when the pigment is in the Dermis (deep) the contrast is not enhanced

~ SALICYLIC ACID alone or in combination with GLYCOLIC ACID

~ TRICHLOROACETIC ACID (TCA) 25% to 35%

~ LACTIC ACID PEEL
