Biology Fragrances is an American fragrance brand founded by Steve Sun that exists to reframe what scent can be. For too long, aromatherapy lived on the margins, either overly clinical or confined to a narrow, niche audience. It saw an opportunity to bring it forward, to make it relevant, wearable, and part of everyday life. Biology Fragrances believes fragrance can do more than smell good. It can shift mood, restore balance, and move with you throughout the day. Every formula is built with intention.
