[sun care] phytophotodermatitis on face. Tips for healing?

Long story short I got lime juice on my face and it burned my skin when laying in the sun. Any tips on how to speed up healing? And lighten the dark spots? Is this a few weeks before it lightens or months? My derm said the dark spots are permanent but we can “save” the pink areas by lathering Vaseline. Day 1-3 I didn’t have access to aloe Vera or anything helpful. It was so red and bumpy (no pus luckily). Day 4 I went to the dermatologist who advised putting Vaseline every hour. The pics are day 4-6 and trust me the dark areas are darker in person. When I look in the mirror I just feel so sad bc it’s so noticeable to me and makes me so self conscious. Any thoughts and experiences help!
