I have been trying out many things trust me to remove tan and soften those lips of mine and I can say I have finally found something that works for me plus it has all natural products that you probably have in your kitchen.
Brown sugar(helps exfoliating yuckiness off if lips)
Drop of lemon(helps remove tan)- you need very less amount else it will burn/tingle your lips.
Drop of coconut oil- to moisturize as well as reduce burning sensation (if any) from lemon drop.
Mix these ingredients and rub it on your lips and wipe it off with splash of water.
Next apply 2 drops of honey on your lips as a lip mask(this will be hydrating).
Wash honey off and apply a dab of coconut oil and see you lips drinking the oil and hydrating your lips.
