Keratosis Pilaris Atrophicans (KPAT) is a relatively rare subtype of keratosis pilaris (KP) characterized by small depressions or pits in the skin’s surface. These pits can appear as multiple tiny depressions that resemble “plucked chicken skin.” KPAT is often associated with hair loss in the affected areas, and it can be challenging to manage.
There are two main forms of Keratosis Pilaris Atrophicans:
Keratosis Pilaris Atrophicans Faciei (KPAF):
- This form affects the face and is characterized by small, depressed pits in the skin, particularly around the eyebrows and cheeks. Hair loss might also occur in these areas.
Keratosis Pilaris Atrophicans Faciei Extensiva (KPAFE):
- Similar to KPATF, but the pits and depressions are more widespread and may extend beyond the face onto the scalp and neck.
Causes: The exact cause of keratosis pilaris atrophicans is not well understood, but it is believed to be related to a combination of genetic factors. It may run in families, and it often begins in childhood or adolescence.
Appearance: The characteristic feature of keratosis pilaris atrophicans is the presence of small, flesh-colored or reddish bumps on the skin, particularly on the face, though it can also affect other areas of the body. The bumps may have a central hair shaft, and they can become inflamed or infected, leading to pustules or redness.
The exact cause of KPAT is not fully understood, but it is believed to be related to the abnormal keratinization of hair follicles, similar to other forms of KP. There is no cure for KPAT, but treatments aim to manage symptoms and improve the appearance of the skin. Management strategies include:
- Topical Treatments: Emollients, moisturizers, and keratolytic agents (agents that promote exfoliation of the skin) can be applied to help smooth the skin’s surface and reduce the appearance of pits.
- Topical Retinoids: Prescription-strength topical retinoids, such as tretinoin, may help stimulate cell turnover and improve the appearance of the affected skin.
- Microneedling: Microneedling treatments can stimulate collagen production and improve the texture of the skin. It might help improve the appearance of the pits associated with KPAT.
- Laser Therapy: Certain laser treatments, such as fractional laser therapy, may be used to promote skin remodeling and improve the appearance of depressions.
- Dermal Fillers: In some cases, dermal fillers might be used to fill in the depressions and improve the overall texture of the skin.
Since Keratosis Pilaris Atrophicans is a relatively uncommon and complex condition, it’s important to consult with a dermatologist who specializes in skin disorders for accurate diagnosis and appropriate treatment options. A dermatologist can assess the severity of your condition and recommend a personalized treatment plan based on your individual needs.
