research Selective follicular targeting by modification of the particle sizes
Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research Photogallery. Follicular occlusion syndrome
The document concludes that four related skin diseases, which often occur together, are caused by blocked hair follicles.
