I loved this product as well and used it for several years. I used the light in winter and medium in spring /summer.
The best alternative I have found is a product by SkinCeuticals:
Physical Fusion UV Defense SPF 50 (1.7 fl. oz.)
A tinted, physical sunscreen that provides broad-spectrum protection.
They have a tinted and a non tinted version called "Sheer".

The tinted will match near all light to medium skin tones and a little goes a long way. It goes on a bit more dewy than the Miracle Skin Transformer product.
If you need more coverage they have another similar product:
SkinCeutical, Physical Matte UV Defense SPF 50
