Humber esthetics grad—want to learn cosmetic chem + CIDESCO cruise questions

Hi all,

I recently graduated from Humber’s Esthetics program and I'm trying to stay curious and keep investing in my knowledge. Right now, I'm really interested in product development—specifically the chemistry side of things. I want to understand chemical composition on a deeper level (like molecular structures and exactly how ingredients interact with the skin) and be able to draw those connections.

With that in mind, does anyone have recommendations for a cosmetic chemistry course I could take?

On a related note, I'm also looking into getting work on a cruise through the London Academy, but I'm a bit confused about how the CIDESCO certification works here in Ontario. I don't think graduating from Humber automatically grants that, so I'm just trying to figure out my options and keep my path open.

If anyone has any insight or knows someone I could connect with, I'd really appreciate it.

Thank you in advance!
