This is a great product. It’s smooth and soothing - great for chapped lips. The flavor is nice too. Best of all, it works! My lips are prone to getting freckles, and I’m not getting any since I started using this. I recommend this, and the sunscreen by the same company. I use SPF 50 for sensitive skin.

Great sunscreen

Size: Pack of 1

Love it! Not greasy, rubs in well, & doesn't smell. Doesn't leave the typical white sheen if you blend in well. Great to add foundation over. Ingredients are less chemicaly than other products.

BEST lip sunscreen I have ever used

Size: Pack of 1

best lip sunscreen I have ever used. Currently in/on Curaçao and no burn! Was out all day yesterday in the sun and this stick was only reapplied 3 times between 8am and 4pm. Reef safe too, that is important to me!
