Background

Gross cystic disease fluid protein 15 (GCDFP-15) also known as Prolactin-inducible protein, extra-parotid glycoprotein (EP-GP), gp17 seminal actin-binding protein (SABP) or BRST2 is a protein that in humans is encoded by the PIP gene. It is upregulated by prolactin and androgens and downregulated by estrogen. The protein has a physiological function in regulation of water transport mainly in apocrine glands in the axilla, vulva, eyelid and ear canal, serous cells of the submandibular salivary gland, serous cells of the submucosal glands of the bronchi, and accessory lacrimal glands as well as cutaneous eccrine glands. It is also found in amniotic fluid and seminal fluid. PIP has the ability to bind immunoglobulin G (IgG), IgG-Fc, CD4-T cell receptor suggesting a wide range of immunological functions. PIP also binds to AZGP1. PIP exerts aspartyl proteinase activity able to cleave fibronectin. Mitogenic effect of PIP was observed on both normal and malignant breast epithelial cells.

The best sunblock I've found!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I absolutely love this sunblock. I have sensory issues with any type of lotion and sunblock, but this stuff is incredible. It really is so lightweight that once it fully soaks in (which only take a few minutes) it feels as if there's nothing on my skin. This is huge for me, cause I just can't handle the feeling of any other sunblocks I've tried, even some more expensive brands. On top of all that, it definitely protects my skin from the sun, doesn't leave a white cast, and doesn't feel greasy while applying it.

My favorite sunscreen for being active outside
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I bought this last summer and now it's my go-to. I love it. It absorbs quickly, is very easy to just smear on, and has a nice, very light scent. I wear it when I go running and I sweat like a maniac so that tells you something.

Possibly the best sunscreen on the US market
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I'm a self-confessed sunscreen snob. I love trying new formulas, and I came to the conclusion years ago that US formulas aren't usually for me. We haven't had a new filter approved by the FDA since the last millennium, and our products reflect that. I can't tell you how many times I spent $40+ on 1.7oz of sunscreen that I ended up hating before I switched to mostly Korean sunscreens; and most of the US sunscreens I like can be described as "good...for a US formula." In short, I didn't have high hopes for this, and I was very pleasantly surprised. This is a very, very good sunscreen even among non-US formulas. It's lightweight, doesn't make my oily skin shiny, and dries down entirely so it doesn't feel tacky or slimy. I can layer over and over throughout the day without pilling or streaks. It also comes in a huge tube for a very low price. The only possible downside is that it's fragranced, which isn't a deal breaker for me. I wish they still sold the 3oz facial version because it's travel-friendly, but from what I can tell, it's the same formula. Try this, especially if you hate thick, heavy, shiny sunscreens. Unless you can't do fragrance, I think you will be very happy with it.

Favorite Sunscreen!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
We absolutely love this SPF. It’s been our go-to for years. It does not make your skin feel sticky or crunchy. It goes on so smooth (like air!) and absorbs so well. It feels like the softest moisturizer. And it works! We get the two pack every summer. It’s also kinda hard to find. Amazon always comes through! Highly recommend.

Fave sunscreen!!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
This is my absolute favorite sunscreen. It got my husband to finally start wearing sunscreen at work- it’s the only one he’ll wear. The texture feels so smooth and lightweight on my skin and it covers very well. It also smells delicious.
