Ocean Potion Sunscreen Lotion SPF 50 is a sheer, non-greasy lotion that glides on easily and absorbs quickly, providing a moisture-rich feel and a fragrance that’s the scent of sunshine.  This formula provides moderate broad spectrum UVA /UVB protection to protect against skin aging and burning caused by the sun.  Enriched with anti-oxidant vitamins B, C & E, deep sea minerals, seaweed and algae extracts to protect your skin and keep it moisturized, nourished and healthy.  Comes in a 6.8 oz tube and is water resistant for up to 75 minutes.

Sun Protection Factor (SPF) of fifty (50) suggests that someone can stay in the sun fifty (50) times longer than if they had no sunscreen on and still be protected from ~98% of UVB rays per Consumer Reports. 

Expiration date is 12/21, but this will be as effective for at least six (6) months after, until at least 6/22, if not longer.  And when it starts to lose it's effectiveness in 6+ months, it gradually does so drops to SPF 45, SPF 40, etc. which still takes several months so this should be pretty effective through at least summer of 2022.
