Functions
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Controls excess oil
Minimizes pores
Traditional Use
This is the CAS number for retinol (Vitamin A). Vitamin A was identified in 1913, and retinol's anti-aging properties were discovered in the 1980s when researchers studying acne treatments noticed significant improvements in skin texture and wrinkles.
