Skin discoloration refers to uneven pigmentation that creates irregular patches of color on the skin. This common concern appears as darkened areas (hyperpigmentation), lightened areas (hypopigmentation), or redness. When skin color becomes uneven, it can significantly impact one’s appearance and confidence.
Melasma appears as symmetrical brown or grayish-brown patches, typically on the cheeks, forehead, nose, upper lip, and chin. This condition is driven primarily by hormonal fluctuations, which is why it’s sometimes called the “mask of pregnancy.” Estrogen and progesterone stimulate melanocytes (pigment-producing cells) to produce more melanin when the skin is exposed to even minimal UV light. Besides pregnancy, hormonal contraceptives and hormone replacement therapy can trigger melasma, which explains why it affects women more frequently than men.
PIH develops after skin inflammation or injury, including acne lesions, eczema flares, or physical trauma to the skin. The inflammatory response triggers melanocytes to increase melanin production as part of the healing process. This excess melanin remains in the skin long after the initial inflammation has resolved, leaving behind dark spots that can range from tan to deep brown depending on skin tone. PIH is more common and typically more persistent in deeper skin tones.
These flat, brown spots result from cumulative sun exposure over the years. UV radiation causes DNA damage to melanocytes, leading to their proliferation and increased melanin production in concentrated areas. Unlike freckles that may fade in winter, solar lentigines remain year-round. They typically appear on areas most exposed to the sun: face, hands, shoulders, and chest, and become more prevalent with age.
Persistent redness results from dilated blood vessels near the skin’s surface. In rosacea, a chronic inflammatory condition, these blood vessels expand too easily and remain dilated, creating visible redness primarily on the central face. Trigger factors like sun exposure, spicy foods, alcohol, and temperature extremes cause blood vessels to dilate further, intensifying the redness. Over time, this chronic inflammation can lead to permanent vascular damage and persistent redness.
Unlike the conditions above, vitiligo causes hypopigmentation—patches of skin that completely lack pigment due to the destruction of melanocytes. This autoimmune condition occurs when the body’s immune system mistakenly attacks its own melanocytes, leaving behind white patches with distinct borders. The exact trigger for this immune response isn’t fully understood, though genetic factors play a significant role.
All skin color is determined by melanin, a pigment produced by melanocytes in the skin’s basal layer. The melanogenesis process (melanin production) involves several steps:
Disruptions at any point in this process can lead to irregular pigmentation. Specifically:
The procedure features Sofcool™ technology, which protects your skin’s surface while allowing the ultrasound energy to work effectively in deeper layers, ensuring a comfortable experience with optimal results.
Skin discoloration can be particularly challenging to address because:
Melanin can be deposited at different levels of the skin. Epidermal (surface-level) pigmentation responds more readily to treatment than dermal (deep) pigmentation.
Hormonal influences, genetic predispositions, and unavoidable UV exposure make some forms of discoloration recurrent despite treatment.
Once the pigmentation pathway is activated, it can create a cycle that perpetuates further pigmentation, particularly in sensitive skin types.
Melanocytes in previously hyperpigmented areas often remain more sensitive to triggers, making those areas prone to repigmentation.
