It is recommended to apply perfume just before entering Ihram, and it is recommended to use Musk, and it does not matter if its glistening traces remain
حَدَّثَنَا يَحْيَى بْنُ حَبِيبٍ الْحَارِثِيُّ، حَدَّثَنَا خَالِدٌ، - يَعْنِي ابْنَ الْحَارِثِ - حَدَّثَنَا شُعْبَةُ، عَنْ إِبْرَاهِيمَ بْنِ مُحَمَّدِ بْنِ الْمُنْتَشِرِ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ عَائِشَةَ، - رضى الله عنها - أَنَّهَا قَالَتْ كُنْتُ أُطَيِّبُ رَسُولَ اللَّهِ صلى الله عليه وسلم ثُمَّ يَطُوفُ عَلَى نِسَائِهِ ثُمَّ يُصْبِحُ مُحْرِمًا يَنْضَخُ طِيبًا .

'A'isha (Allah be pleased with her) reported:
I used to apply perfume to the Messenger of Allah (ﷺ). He then went round his wives, and entered upon the state of Ihram in the morning and the perfume was shaken off.
