Do you girls experience times where when you apply your lipstick/lip colors and it turned out very unnatural, uneven color and even chappy?
This is a simple trick for you to solve this problem ! =D
1st : Apply lip balm !
Lip balms can smoothen your lips, and make them less chappy. Which helps to make lip color turns out evenly.
2nd : Apply your lipstick
This time, the color should be even. However, it may still look a little bit unnatural.
3rd : Blend them with your fingers !
Now, it should be looking fine now. In case you smudges it out of you lips, gently wipe them off with a cotton bud.
4th [Additional] : Pouty lips?
You can get this result by applying a little bit of foundation.
Apply your foundation towards the edge of you lips[the part which you draw lip line??].

Well, that's all.
Do feedback to me if this works for you =)
It works well for me though.
