before applying lipstick on the lips one should put a little foundation layer on the lips and then one should apply the lipstick. It helps the lipstick stays longer on the lips. One can put slight Vaseline or moisturizer on the skin to keep the lips soft so that lips are not dry. When applying matt finish lipstick it's a better option to apply some balm, Vaseline or moisturizer on the lips. After applying the lipsticks if one doesn't find the shade suiting the lips and skin one can blot it off with a clean tissue paper keeping between both the lips and then one can wipe it off with a cotton ball having cleanser or moisturizer on it.
The trick to make thin lips appear thick and full is drawing a line outside the lips with a darker shade of lipstick and then fills the lips with foundation, and then apply lipstick in the outlined area. One should wear lighter shades to make the lips look thicker. To portray thick lips a little thinner one should wear darker shades on lips and when putting the lipstick one should make line inside the natural shape of the lips. Lipstick should be filled under this line to make lips appear thinner than they naturally are.
