Sunscreen or moisturizer first?

I always apply sunscreen/sunblock(Chemical/physical) after my moisturizer. Sunscreen are always the last step of my day time skincare routine and before primer or foundation. But lately, I learned that it's the other way round...

It's doesn't have any definite answer but according to Dr. Neal Schultz, he said that the active chemical sunscreen ingredients need time to bind with the skin for about 20 to 30mins before we head outside, so it is best to apply on bare skin.

As for the physical sunscreens (the one that contain Titanium Dioxide and Zinc Oxide), it's ok to be applied both before or after moisturizer. However, some experts think that it is best to apply on clean, bare skin before using any other skincare products. Because some of the ingredients in our moisturizing can interfere with the sunscreen and make them less effective.

Anyway, nowsaday, most sunscreen contain both chemical and physical ingredients (which will absorb and block at the same time.)

There's also some doubts about the thicker consistency of sunscreen, cos we all know that we always applied the lighter texture products first.. so, the moisturizer might not be able to absorb into the skin, if we use the sunscreen first (this question is still unclear...)

So my thought was, either choose a lighter texture sunscreen or use a sunscreen that can be double up as moisturizer .. there, no more layering of products! lolx

I enjoyed watching his Q&A videos... always very informative ^_~

Different between Physical and Chemical sunscreen
  • Physical sunscreens protect your skin from the sun by deflecting or blocking the sun's rays.
  •  Chemical sunscreens work by absorbing the sun's rays. Some chemical filters can scatter sun rays, but still mostly just absorb them.
Anyway, I just realised that most sunscreens that I've used contain both physical and chemical ingredients...

So do you apply moisturizer first or sunscreen first???

I've tried applying sunscreen (I'm using The Face Shop Natural Sun Shaking AQ base sun milk - which is a combination of physical and chemical ingredients) before moisturizer and I like how it feel, well... it's doesn't feel much different but the sunscreen absorb faster and when I apply moisturizer, my skin doesn't feel thick and the moisturizer absorb well and doesn't feel heavy nor stuffy! (Thumb up!!)
