Common questions
What supplements are good for skin?
Collagen (with vitamin C, which is required to build it), hyaluronic acid for hydration, omega-3 for the skin barrier, and astaxanthin as a protective antioxidant.
Does collagen actually improve skin?
A growing body of trials suggests hydrolysed collagen can improve skin elasticity and hydration over 8-12 weeks. Pair it with vitamin C for best results.
