Another popular treatment for the skin, namely the face, collagen facials increase or stimulate collagen production. This not only helps to revitalise the skin but to also slow down the ageing process which a great many of us desire! This kind of treatment is not just relegated to beauty clinics however and are now available at wellness retreats around the world. Those staying at a Hunter Valley spa resort in New South Wales, Australia for example, at properties like Elysia Wellness Retreat can enjoy such collagen facials; utilising pure collagen extracts, these treatments will help one's skin to be smoother while leaving a healthy glow too.
