Definition
Skin feel, also called skin chemistry, describes how a perfume composition evolves on individual skin. Skin pH, sebum, body temperature and hydration shape the volatility and retention of the aromatic molecules. It is a technical fact, not a subjective impression: the same fragrance smells different on two people.
Key factors
Healthy human skin sits at a pH between 4.5 and 6.5, most often around 4.5 to 5.5 (source: Regal Parfumes). On more acidic skin, citrus top notes built on compounds like the linalyl acetate of bergamot volatilize faster; vanillin and amber notes read as less sweet.
Skin temperature averages 32 to 34 degrees Celsius, and pulse points (wrists, neck, inner elbows) run up to 2 degrees warmer, which accelerates diffusion (source: Snif).
Use in perfumery
Sebum acts as a natural fixative. Oily skin holds heavier notes (musks, ambers, oud) longer and extends longevity; dry skin lets the fragrance evaporate up to 50 percent faster (source: Scento). Moisturizing before application stabilizes the pyramid and improves projection. Diet, hormones and medication can shift skin chemistry temporarily; the English-speaking niche community sometimes calls this final, personal evolution the drydown effect.
