Ashwagandha

Lower cortisol, raise testosterone

600mg of KSM-66 ashwagandha extract daily. Clinical trials show it reduces cortisol by up to 30%, which directly benefits skin (cortisol degrades collagen and drives acne), improves testosterone levels in men by 10–15%, and reduces the stress response that causes puffiness and dull complexion. Effects are noticeable within 4–8 weeks.
