Many scientific studies have been conducted on the effectiveness of Aloe Vera in soothing irritated skin.  With so many anti-aging products comprised of various acids-- which are truly irritants used in a controlled fashion to exfoliate and plump the skin-- Aloe Vera has become a hard-working ingredient and natural calming agent. Aloe Vera increases the availability of oxygen to the skin and strengthens skin tissues. The anti-burning properties of Aloe combined with SPF factors make this an excellent skin care product.
