I finally found the culprit. It's not the face powder, it's actually the base. It make sense since the product have pretty high SPF.
The sample is pretty generous. 30g each.
The product is in super light mousse form. I believe the sample I got is 'beige' version. There are also pink and BB beige. BB beige is the limited shade in Mika Ninagawa collection.It's too early to write a review for this product. So I'm just gonna swatch it in this post.
Swatch w/o flash: I apply the base only at the left side. The white cast can be seen here.
It become more obvious with flash. So, basically, this product is not good if you're taking picture.
But the good thing is that, the area where the base applied look more even and smoother. I think I'm gonna reserved this as sunscreen for the day I'm playing volleyball.
