Can I use melawash facewash in the morning and almond oil at night?

My face skin got burn internally due to some chemical reaction and lost all brightness and moisture. I consulted a dermatologist and he gave me 5% hydroquinone as night cream but i didnt use it considering its side effects but taking pills Qtvit plus and gse+ace my skin improved but not as much....its was earlier. Is it safe to use almond oil while taking these pills and melawash face wash?
