So I decided to branch out. I did this fairly unscientifically: I decided to try some of the other Biore sunscreens, since they have a billion different ones, and I chose ones that I could get on Amazon with free shipping. Originally, I ordered Biore Bright Milk and Biore Face Milk, but after waiting for them for 11 weeks and them not showing up, I ordered Biore Perfect Milk. Bright Milk and Face Milk arrived a few weeks later, the day before Perfect Milk showed up (which only took three weeks, from Japan). And having three similar but different sunscreens to play with has been very educational. For the first few weeks, I alternated them, wearing a different one every day. After that, I picked one and wore it every day for two weeks, before switching to a new one. And now, I feel ready to give my thoughts on them.
L-R: Face Milk, Bright Milk, Perfect Milk
Bright Milk has a very slight pink tint. It's fairly liquidy, and has no real scent. It reminds me of calomine lotion because of these two things. This one is my favourite of the three - they're all pretty similar, but the slight pink tint of this helps smooth my skintone out and gives a great glow under my foundation. It's got a slightly powdery finish when it dries, but overall helps battle the potential greaseface that is so common in the humid, awful summer.
Face Milk is a white liquid, with the same consistency as Bright Milk. As far as I can tell, it's exactly like Bright Milk except it doesn't have a slight pink tint. It has the same finish, but seems to have a slight white cast. I think. Being pretty fair, it's hard to tell and it's also not something I concern myself much with, since a white cast has the effect of evening my skintone rather than looking ashy.
Perfect Milk is also a liquidy white sunscreen, very similar to Face Milk. The only discernible difference I can find between the two is that Perfect Milk is a little more powdery when it dries down. It also has no real scent, and a slight white cast.
All three wear well under my makeup. Once they've sunk into my skin, I don't feel them. They're all really, really similar to one another, but the Bright Milk edges out the others for doing something slightly more obvious to my skin as well as having a wonderfully shimmer pink package and I love it unabashedly. Because the pink bottle is what really counts.
