Familial Progressive Hyperpigmentation (FPH) is a genetic skin condition that causes dark patches on the skin that intensify with age. If you or someone you know is experiencing this, reach out to a dermatologist for advice and possible treatment options. It is a skin condition where specific areas of your skin start to get darker over time. This happens because of an increased production of a pigment called melanin. Melanin is responsible for giving color to your skin, hair, and eyes. When there’s an overproduction of melanin in certain spots, those spots become darker, forming patches on your skin.
Familial Progressive Hyperpigmentation, or FPH for short, is a skin condition where certain areas of the skin become darker over time. “Familial” means it tends to run in families, “progressive” indicates it gets more noticeable as time goes on, and “hyperpigmentation” is a fancy word for when parts of your skin darken.
The Main Types of FPH
While FPH is unique, it has been divided into a few types. Knowing these will give you a clearer picture:
- FPH with or without Lentigines:
- What it is: This is when the skin becomes more pigmented (darker) in patches. Sometimes, small dark spots called lentigines might also appear.
- Why it matters: These changes are usually harmless, but it’s good to know what to expect if a family member had it.
- FPH with Systemic Changes:
- What it is: Along with the skin darkening, some people might experience changes in other parts of their body.
- Why it matters: Understanding this type means being proactive about the whole body, not just the skin.
Types of Familial Progressive Hyperpigmentation:
- Type 1: Lentigines
Lentigines are small, dark spots that appear on the skin. They are usually harmless but can be quite noticeable. These spots are more common in areas that are exposed to the sun, like the face, hands, and arms. They are often referred to as “sunspots” or “age spots.”
- Type 2: Ephelides (Freckles)
Freckles are small, flat spots that are usually tan or light brown in color. They tend to appear on people with fair skin and often become more prominent during sun exposure. Freckles are not harmful, but they can be a concern for cosmetic reasons.
- Type 3: Café-au-Lait Spots
Café-au-lait spots are light brown to dark brown patches that resemble the color of coffee with milk. They can be present from birth or develop during childhood. While these spots are generally harmless, having multiple café-au-lait spots might be associated with certain genetic conditions.
- Type 4: Melasma
Melasma is a common type of hyperpigmentation that occurs as gray-brown patches on the face, most commonly on the cheeks, forehead, bridge of the nose, and upper lip. It’s often triggered or worsened by hormonal changes, such as pregnancy or birth control use.
- Type 5: Post-Inflammatory Hyperpigmentation
This type of hyperpigmentation occurs after the skin undergoes inflammation due to various reasons like acne, burns, cuts, or other injuries. As the skin heals, it can leave behind darker patches that take time to fade away.
- Type 6: Riehl’s Melanosis
Riehl’s melanosis is a less common type of hyperpigmentation that appears as gray-brown patches on the face and neck. The exact cause is not fully understood, but it’s thought to be related to sun exposure or certain cosmetics.
Causes
Potential causes broken down in easy-to-understand language, perfect for everyone:
- Genetics: Just like you inherit your eye color from your parents, some people inherit genes that make them more prone to skin darkening.
- Hormonal Changes: Hormones, like those that change during pregnancy or puberty, can cause the skin to darken.
