This is a new unused One Skin OS-01 Senescence Blocking Peptide Shield Untinted SPF 30+ mineral sunscreen. Travel size 1.35 fl oz. Made in the USA with Zinc Oxide as the active ingredient. I did open the box from the top and opened the container and when I did the little seal came off in the lid. This was NOT used at all and All of the product is in it still. This was purchased very recently. Perfect for carryon baggage while traveling, small for your purse or to try before buying the full size.
