Five Star Gift Ideas

A potential gift idea for your boyfriend who likes cosmetic chemistry could be a DIY cosmetic chemistry kit. This kit would include ingredients commonly used in cosmetic chemistry, along with a guidebook or online course to provide ideas and knowledge on how to make different kinds of beauty and skincare products. The kit could also include all necessary equipment such as beakers, measuring cups, and pipettes. This would allow your boyfriend to experiment with creating his own personalized products and exploring the science behind the beauty industry. Another option could be a book on the history of cosmetic chemistry, such as "Making Up: A Chemical History of Makeup" by Christine Cosgrove. This book explores the science behind cosmetic ingredients and how they have evolved over time, making it a great fit for someone interested in the field.

Or you can get him a star map with the date of your first kiss.
