HG foundation formula changed to something I can't wear. Help?

Hey y'all.

They added chemical sunscreen to my favorite bb cream - Dr. Jart detox. I can only use physical sunscreen because I have extremely reactive skin.

I like a really luminous medium coverage and I have a weird pale olive undertone. The grey/green tone in the Detox BB worked SO well for me (related: I cried in a Sephora today).

Does anyone either a) know somewhere I can buy an unreasonable amount of the old formula or b) have a recommendation for something similar?

Thank you, beautiful people!
