So I won two coupons for a full tube of this lip balm. The original price is 3.89. Here in MI at Walmart. I got them for free. A month ago they were only spf 4. It does hydrate the lips instantly. It is lightweight which is nice. The smoothness comes from the shea butter and aloe: it feels nice on sunburnt lips. It claims to be long-lasting but I found myself reapplying every two hours.
