Functions
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Masking
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Skin Protecting
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Tonic
Nourishing
Protecting
Traditional Use
St. John's Wort has been used in European folk medicine since ancient times for skin healing, mood support, and wound care. Traditionally used by herbalists and in traditional medicine for over 2,000 years.
