The edges of my lips are dark.

The edges of my lips tend to be quite dark.

I've always found dark colors really stressful, and I struggle with it every time I apply lip tint.

My preferred shades are light pink or coral, but whenever I try light, delicate colors, the pigmentation never shows up well. I end up having to keep layering them to achieve a darker look, and even when I try to apply it naturally, it never turns out the way I want, so I always feel disappointed. It's really bothering me. Please give me some tips!
