Is it permissible to treat hyperpigmentation with a laser by a male doctor, given the possibility of other complications, and knowing that the face and neck must be uncovered?

It is permissible for a woman to treat pigmentation, vitiligo, and similar conditions, because their persistence can cause psychological harm, and because their removal beautifies and improves, which is desirable for a woman, especially a married one. Ibn al-Jawzi and al-Ayni mentioned the permissibility of medicines that remove melasma and improve the face for the husband. Sheikh Zaydan stated that mentioning the husband is not a restrictive condition; rather, it is permissible for married and unmarried women, as well as for men, provided that the treatment has no side effects and is not accompanied by any religiously prohibited acts.
