Using lipstick to make the lips more full
Question

                Recently it has become common to use lipstick that makes the lips temporarily more full, then they go back to their natural state. My question is: What is the ruling on buying or selling this lipstick? Is it regarded as altering the creation of Allaah? Please note that it make the lips more full temporarily.
Praise be to Allah.Using this lipstick is not 
    regarded as altering the creation of Allaah, rather it is a temporary 
    adornment, like lipstick, kohl and so on. But the permissibility of its use 
    is limited to a number of things: 
1 – It should not be 
    harmful to the skin, because of the general meaning of the words of the 
    Prophet  (peace and blessings of Allaah be upon him): “There should be 
    neither harming nor reciprocating harm.” Narrated by Ahmad and Ibn Majaah 
    (2341); classed as saheeh by al-Albaani in Saheeh Ibn Majaah. 
So one should make sure 
    that this substance is safe and suitable for the skin.  
2 – Using it should not be 
    an imitation of kaafir or immoral women, such as if a woman wants to use it 
    to look like So and so among those woman, because of the general meaning of 
    the evidence which forbids imitating kaafir and immoral women, such as the 
    words of the Prophet  (peace and blessings of Allaah be upon him): 
    “Whoever imitates a people is one of them.” Narrated by Abu Dawood (3512); 
    classed as saheeh by al-Albaani.  
3 – Using it should not 
    involve any kind of extravagance, because Allaah says (interpretation of the 
    meaning): 
“and 
    waste not by extravagance. Verily, He likes not Al‑Musrifoon (those who 
    waste by extravagance)”
[al-An’aam 6:141]
Extravagance means spending 
    too much money on permissible things. 
Some women spend a great 
    deal of money on these cosmetics, following fashion or seeking so-called 
    beauty, when there may be no need for that. If she spent this money or some 
    of it on feeding a hungry person or clothing a poor person, that would be 
    better for her and bring a greater reward. 
And Allaah knows best.
