One idea for an anniversary gift for your boyfriend who enjoys makeup artistry could be to purchase him a makeup masterclass with a professional artist. This could be either an online course or a live in-person class. You could also consider gifting him some high-quality makeup products or professional-grade brushes that he may enjoy using in his art. Another option could be to purchase him a book or a subscription to a magazine that provides resources and inspiration for new makeup techniques and ideas.
Or you can get him a star map with the date of your anniversary.
