Lip balm that changes color in response to skin pH. - Product Name: Moodmatcher RG Orange - Color: Orange - Size: Stick type Thank you for viewing. I really like this lip balm because it lasts longer than any other I've used, but I bought several and they haven't run out, so I'm selling a new one. I really recommend this to those looking for a long-lasting lip product. If you use this as a base and apply lipstick on top, even if the lipstick comes off, your lips will still have color, which is great.
