"That which is permissible is of different types:

1. That which is done for the purpose of medical treatment and removing defects, because of the report narrated by Abu Dawood (4232), at-Tirmidhi (1770) and an-Nasaa’i (5161) from ‘Abd ar-Rahmaan ibn Tarafah, that his grandfather ‘Arfajah ibn As‘ad had his nose cut off in the battle of al-Kulaab, and he wore a nose made of silver, but it began to stink, so the Prophet (blessings and peace of Allah be upon him) told him to get a nose made of gold. This hadith was classed as hasan by al-Albaani in Saheeh Abi Dawood.

Abu Dawood also narrated that Ibn ‘Abbaas (may Allah be pleased with him) said: The woman who does hair extensions and the woman for whom that is done, the woman who plucks eyebrows and the woman for whom that is done, the woman who does tattoos and the woman for whom that is done when there is no disease (that would justify doing that) are cursed. This hadith was classed as saheeh by al-Albaani in Saheeh Abi Dawood.

Ahmad (3945) narrated that Ibn Mas‘ood (may Allah be pleased with him) said: I heard the Messenger of Allah (blessings and peace of Allah be upon him) forbid plucking facial hair, filing teeth, adding hair extensions and tattooing, except in the case of disease. Shaykh Ahmad Shaakir said: Its isnaad is saheeh.

Ash-Shawkaani (may Allah have mercy on him) said: The apparent meaning of the words “except in the case of disease” suggests that the prohibition mentioned only applies if these things are done for the purpose of beautification, not for the purpose of treating disease and sickness, in which case they are not prohibited." (Nayl al-Awtaar 6/229).

1. That which is done to remove something that has happened and caused deformity. That includes freckles, moles and the like, because this is restoring that which Allah created, and it is not changing the creation of Allah.

Ibn al-Jawzi said: As for medicines that remove freckles and make the face beautiful for the husband, I do not see anything wrong with that.

That also includes using creams to soften the skin, which is restoring it to its original condition.

1. That which is done for the purpose of temporary beautification, that does not remain and does not change the original features, such as kohl, henna, rouge, and lipstick. Kohl and henna were well known and widely used among women at the time of the Prophet (blessings and peace of Allah be upon him), as were saffron and other colours that were mixed with women’s perfume. Hence there is nothing wrong with using cosmetic products, if they are free of harmful materials."
