The Dermatology of Keratosis Pilaris & Follicular Hyperkeratosis
Keratosis pilaris (KP) occurs when the body overproduces keratin, forming microscopic hard plugs inside hair follicle openings across the upper arms and thighs. Attempting to scrub these away with harsh, gritty abrasives inflames the surrounding tissue, causing redness and post-inflammatory pigmentation.
Chemical exfoliants solve this by breaking desmosome bonds. Alpha Hydroxy Acids (glycolic and lactic acid) gently dissolve surface dead cells, while lipophilic Beta Hydroxy Acid (salicylic acid) penetrates inside the lipid-rich pore to dissolve the trapped plug at its source.
The Four Distinct Exfoliating Textures Compared
Acid Gels: Fluid, surfactant-rich washes that work purely through chemical dissolution without physical friction; ideal for daily use and sensitive skin.
Micro-Pumice Scrubs: Suspended fine mineral particles in a rich cream base that provide instant mechanical smoothing for coarse spots like heels and elbows.
Gommage Creams: Plant-cellulose pastes that roll into soft friction beads as you massage, lifting dead flakes without scratching.
Enzyme Foams: Fermented papaya (papain) or pineapple (bromelain) enzymes that selectively digest dead keratin proteins while sparing living cells.
