Praise be to Allaah.
Taraaweeh prayer is prescribed for men in congregation in the mosque at night in Ramadaan, because the Prophet (peace and blessings of Allaah be upon him) said: “Whoever stands with the imams until he finishes, it will be written for him as if he spent the whole night in prayer.” (Narrated by al-Tirmidhi, 806; classed as saheeh by al-Albaani in Saheeh Sunan al-Tirmidhi)
Nevertheless, if a man prays Taraaweeh at home, there is no sin on him and his prayer is valid. At times other than Ramadaan, it is prescribed for a man to pray qiyaam al-layl at home.
With regard to women, it is better for them to pray at home, but if a woman wants to pray in the mosque, she should not be prevented from doing so, because the Prophet (peace and blessings of Allaah be upon him) said: “Do not prevent your women from coming to the mosques, but their houses are better for them.” (Narrated by Abu Dawood, 567; classed as saheeh by al-Albaani).
And he (peace and blessings of Allaah be upon him) said: “Do not prevent to slave women of Allaah from coming to the mosques of Allaah.” (Agreed upon; al-Bukhaari, 900; Muslim, 442).
With regard to putting cream on the face and body, there is nothing wrong with that. See Question # 2299. And Allaah knows best.
