Lovely foundation, but shade range is a bit confusing/could be expanded
I will say that Surratt offers services for shade selection, so I do give kudos for that. I do think that with their odd numbering system, they could provide more models/examples to better illustrate exactly what the shade differences and selections are. I personally use shade 11, which is a tad light but works when mixing with shade 13 to provide a hint more depth.
Onto the formula itself, I find this to be an absolutely stunning foundation. It is not a high coverage foundation, and I'd argue it is light-medium at best, but I find it to be perfect for both everyday use and even as a combo-oily skin person, it only breaks slightly around my nose after 6+ hours of wear. I'm not sure if this would hold up as well on my skin in the summer, but all things considered I find it to be a lovely foundation to use, and I'm glad to have it in my makeup collection.
