I've been loving Skinceuticals Physical Fusion UV Defense SPF 50
(link to product info & ingredients) for a long time now, but the price is quite expensive. So I found that the brand is owned by L'Oreal and that they have recently released a similar product at a lower price point, Advanced Suncare Silky Sheer BB Face Lotion SPF 50+
(again link to info & ingredients). The ingredients are different so this may not be exactly the replacement I'm looking for. Could you explain the difference?
