I’m Betty Gordon, and I’ve spent more years than I can count elbow deep in soap batter tweaking, testing, and occasionally ruining a few batches so you don’t have to. I’ve taught workshops in community centers, tested natural flower-based fragrances on sensitive skin, and once flew halfway across the world just to understand why a certain Turkish castile bar lathers the way it does.

I noticed a troubling pattern: misinformation. Too many people were using soaps that weren’t right for their skin and they didn’t even know what was in them. That’s why I started Sun Gold Soaps. Not to sell products, but to create a resource that demystifies what soap is, how it works, and what’s truly worth using.

So Sun Gold Soaps exists not to push a product, but to share answers. Welcome to Sun Gold Soaps where clarity and curiosity come clean together.
