Detoxifies and firms the skin: Bladderwrack extract has been documented to improve skin elasticity and hydration. Its antioxidants combat free radicals, and the extract may stimulate circulation when applied (hence its use in cellulite and firming creams). It also provides minerals that nourish the skin. In one study, a cream with bladderwrack improved skin elasticity measurably after 5 weeks. Traditional use and some spa therapies employ Fucus for its skin-protective and anti-inflammatory benefits – helping with conditions like eczema.
