A whiter shade of pale?

I use Neutrogena spf 55 for my sunscreen, at my dermatologist's recommendation.  But I've been using CeraVe a.m on my face (also at her recommendation).  CeraVe contains ceramides, which are supposed to be good for the skin, and is available at drug stores for around $15--quite a bargain compared to the expensive department store products.  But CeraVe a.m. doesn't say it's broad spectrum, so I thought I needed to switch to something that would block both UVA and UVB rays.  (According to Wikipedia, UVA rays can increase the rate of melanoma--and many sunscreens do not block UVA rays.)

CeraVe has a new facial sunscreen product that's SPF 50 (CeraVe a.m. is SPF 30) and the tube says it's a broad spectrum sunscreen.  I'm looking at the two products side by side--the difference is that CeraVe sunscreen face lotion has more zinc oxide (4.7% vs 3.5% for a.m.) and also has titanium dioxide; CeraVe a.m. does not have titanium dioxide.

According to WebMD, the following ingredients protect against the melanoma-causing UVA rays:  ecamsule, avobenzone, zinc oxide and titanium dioxide.  (Neutrogena has avobenzone.)  So the CeraVe sunscreen face lotion has better  UVA protection than CeraVe a.m.  I tried the sunscreen face lotion this morning--I looked like I was making up to be in a Noh drama--I got that "ghostly white" look that one website said used to be a problem, but no longer was with newer versions of products containing zinc oxide.  Oops, they were wrong.  The CeraVe instructions on the back of the tube say the product "...spreads easily and dries with a clear finish..."  Clear white, that is.

I'm not giving up on the CeraVe sunscreen--I really like CeraVe products.  And if the sunscreen face lotion helps protect against (more) melanoma, then I'll just have to look a bit ghostly.
