Keratosis Pilaris Atrophicans Faciei (KPAF) – Diagnosis and Treatment Guide
📌 Patient Information Section: What Does This Condition Mean?
Keratosis Pilaris Atrophicans Faciei (KPAF) is a rare hereditary skin and hair/eyebrow condition, typically beginning in childhood or adolescence, characterized by the obstruction of hair follicles with a hard substance called keratin, and over time leading to permanent atrophy (thinning/depression) and hair loss around the follicles.
- Affected Areas: Most commonly observed on the cheeks, in front of the ears, and on the outer parts of the eyebrows, presenting as redness, bumpiness, and subsequent permanent hair loss (thinning of eyebrows). It can also extend to the scalp borders.
- Symptoms: Small, punch-out-like depressions (atrophy) in the skin, follicular papules, and permanent hair loss.
- What to Do: Standard moisturizers do not reverse this condition. Early dermatological follow-up and keratoregulatory treatments are essential to prevent permanent scarring and tissue loss.
🩺 Clinical & Medical Guide for Physicians
- Etiology and Pathophysiology: Abnormal keratinization of the follicular epithelium, obstruction of the follicular ostium, formation of a keratin plug within the follicle, and accompanying mild inflammation that destroys the follicular structure, leading to cicatricial (atrophic) loss (autosomal dominant forms have been reported).
- Diagnostic Criteria and Clinical Findings: Symmetrical erythematous follicular papules on the cheeks and eyebrow area, follicular keratotic plugs, permanent cicatricial alopecia on the lateral eyebrows, and "atrophic depressions" (vergetures / ice-pick-like scars) on the face. Differential diagnosis with frontal fibrosing alopecia may be necessary.
- Dermoscopy (Trichoscopy) Findings: Yellowish-white keratin plug rings obstructing hair ostia, peri-follicular erythema around them, and fibrotic/atrophic white areas (areas where hair follicles are absent).
- Histopathological Diagnosis (Punch Biopsy):
- Biopsy Indication: A 4 mm punch biopsy is taken in cases of atypical cicatricial alopecias and those confused with follicular keratoses.
- Pathology: Obstructed keratin plug in the infundibulum, atrophy of the follicular wall, loss of elastic fibers in the dermis, and mild perivascular/perifollicular lymphocytic infiltrate.
- Current Treatment Protocols:
- Keratolytic and Retinoid Treatments: Removal of keratin plugs with topical retinoic acid, salicylic acid, or urea-containing creams. Systemic isotretinoin (low dose) may be used in selected resistant cases to suppress fibrosis.
- Laser and Cosmetic Approaches: Vascular lasers for erythema, fractional laser (e.g., 585 nm diode or fractional solid-state lasers) applications for atrophic scars. Additionally, expert and treatment approaches can be reviewed for clinical and surgical evaluations.

Keratosis Pilaris Atrophicans Faciei (KPAF) and Hair/Eyebrow Involvement Frequently Asked Questions
Questions about KPAF, follicular keratosis on the face and scalp, scarring alopecia processes, and treatment approaches, with the expertise of Dr. Muhammet Özgehan's Clinic.
Keratosis pilaris atrophicans faciei (KPAF) is a rare group of scarring alopecias, typically beginning in childhood or adolescence, characterized by redness on the cheeks, keratotic plugs in the hair follicles (a shriveled, bumpy appearance), and over time, atrophy (skin thinning) in these areas. Dr. Muhammet Özgehan states that one of the most characteristic features of this condition is progressive hair loss and thinning, especially in the outer third of the eyebrows.
Yes, because KPAF belongs to the "atrophicans" (atrophy-causing) group, inflammatory processes in the hair follicles eventually lead to fibrosis (scar tissue). This can result in permanent follicle loss, particularly in the eyebrow roots and certain areas of the hairline. Dr. Muhammet Özgehan emphasizes that if early-stage inflammation is not suppressed, follicles can be irreversibly lost, leading to scarring.
The primary goal of treatment is to reduce skin redness and inflammation, eliminate follicular obstructions, and slow down scar development. Current approaches applied at Dr. Muhammet Özgehan's clinic include:
- Topical and Medical Keratolytic Protocols: Special creams and anti-inflammatory solutions prescribed under medical supervision that dissolve plugs on the skin surface.
- Laser and Light Therapies: Selected laser applications to control capillary dilation (redness) and inflammation on the cheeks.
- Clinical Follow-up and Supportive Cures: Dermatological supportive treatments aimed at preserving tissue health around the eyebrows and hair.
Hair or eyebrow transplantation is absolutely not performed during periods when the disease is active and skin inflammation persists. Dr. Muhammet Özgehan states that tissue nutrition is impaired in areas with atrophy and scarring, and therefore, surgical intervention may be unsuccessful unless the disease is completely stabilized and remains quiescent for years. However, in very specific and calm cases, eyebrow or hair restoration may be considered under medical supervision.
Daily care is of great importance in this condition where the skin barrier is sensitive. Dr. Muhammet Özgehan offers the following recommendations to individuals diagnosed with KPAF:
- Absolutely avoid harsh scrubbing or aggressive peeling procedures that may irritate the face and hair area.
- Use high-factor UV protectors to shield the skin from the harmful effects of sunlight.
- Seek dermatological follow-up at the clinic without delay if redness, flaking, or sensitivity increases.
