One idea could be getting him a DIY chemistry kit where he can make his own cosmetic products such as shampoo, soap, and lotion from scratch. Another idea could be a subscription to a cosmetic chemistry magazine or textbook to keep up with the latest developments and techniques in the field. You could also consider getting him a personalized lab coat or mug with his name on it to use during his experiments. Lastly, you could purchase a gift certificate for him to attend a cosmetic chemistry workshop or seminar to network with other enthusiasts and learn more about the subject.
Or you can get him a star map with the date when he was born.
