Keratosis pilaris (Pileoporosis pilaris) is a widespread but overlooked skin condition. Those affected often suffer from small, rough bumps, usually on the upper arms, thighs, or buttocks. The skin feels uneven and dry, and appears permanently covered in goosebumps. Although it's a harmless condition, many people find the skin condition bothersome—especially in summer. Conventional treatment is often laborious, involving creams or peels—and rarely permanently successful. This is where PRP (platelet-rich plasma) comes into play as a modern alternative. But can this method really help?
What exactly happens with sandpaper skin?
In keratosis pilaris, the skin produces too much keratin – a protein that clogs the hair follicles. This causes the characteristic, hard, small bumps. The condition often runs in families, occurs in people with dry or sensitive skin, during puberty, or during hormonal fluctuations. While the skin change is not dangerous, it is persistent – and particularly difficult to treat with conventional care.
Why PRP is a new approach
PRP is extracted from your own blood and contains a high concentration of growth factors that promote skin renewal. It supports cell regeneration, promotes collagen production, and has a soothing effect on irritated skin. In areas where the skin is rough, thickened, or irregularly textured, PRP can strengthen the barrier function and stimulate the formation of new healthy skin cells. The key advantage: It not only treats symptoms but also promotes skin restructuring from within.
How does PRP treatment for sandpaper skin work?
After a simple blood draw, the PRP is prepared and injected into the affected areas or introduced via microneedling. The mechanical stimulation plus PRP activates targeted repair processes. The treatment lasts approximately 30 minutes, is well tolerated, and involves minimal downtime. Redness or slight swelling usually subsides within a day.
The first visible improvements often occur after two to three sessions. For lasting results, a course of three to five treatments, each four weeks apart, is generally recommended.
Who is PRP suitable for when it comes to sandpaper skin?
People with:
-
chronically rough skin on arms or legs,
-
therapy-resistant keratosis pilaris,
-
sensitive skin that does not tolerate acid peels,
-
genetic predisposition to keratosis pilaris.
PRP also represents a promising solution for people with cosmetic problems who are looking for a form of therapy that is as natural and non-irritating as possible.
Conclusion
Keratosis pilaris may be harmless, but for many, it's a persistent, burdening skin problem. PRP offers an innovative treatment approach that relies on the body's own regeneration rather than superficial exfoliation. With its anti-inflammatory, smoothing, and cell-stimulating effects, PRP can significantly improve the appearance of keratosis pilaris – gently, effectively, and long-term.
