What Are Some Good Ways to Discover Local Small Businesses in Belgium?

I've been trying to get better at discovering smaller businesses and independent brands in Belgium, but I find it difficult to know where to look beyond the usual big retailers and shopping websites.

I'm particularly interested in finding local or independent beauty and lifestyle brands. I recently came across Michaelan while exploring online options, and it made me wonder how other people usually discover smaller brands they haven't heard of before.

Do you usually find new businesses through local recommendations, social media, community groups, or online directories? I'd be interested to hear how others discover and support smaller businesses in Belgium.
