Background

Prolactin (PRL), also known as lactotropin, is a protein best known for its role in enabling mammals to produce milk. Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and nursing. It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. Prolactin levels may be checked as part of a sex hormone workup, as elevated prolactin secretion can suppress the secretion of follicle stimulating hormone and gonadotropin-releasing hormone, leading to hypogonadism and sometimes causing erectile dysfunction. Prolactin levels may be of some use in distinguishing epileptic seizures from psychogenic non-epileptic seizures. The serum prolactin level usually rises following an epileptic seizure.

I hate sunscreens, but...
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I hate sunscreen in general--for it's texture and smell. But, being the palest family on Earth makes it a daily necessity. I was pleasantly surprised to actually like the smell of this product! It's a light fruity fragrance. It has a smooth texture like lotion and glided on my skin without being too thick or greasy and no white marks. A little goes a long way too! I could hardly believe I was putting on sunscreen and not regular body lotion. My kids had no issue with it either! They let me put this stuff on their little faces without complaint since it goes on so smoothly. Most importantly, this product did it's job and we were sunburn free. The tube is small--4 ounces--but I don't care because it's so worth having something that goes on easy and doesn't make us greasy and stinky. I bought several tubes--one for each member of the family. *If this review was helpful, please click 'yes' below. Thanks!*

It’s ok
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
Doesn’t smell like anything, especially not fruit. Seems to work well- it’s what we use on our faces. I started using this all over on my daughter because their spray version is not good.

Overall this is a very good product
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I bought this because every sunblock I own eventually gets in my eyes and burns the living daylights out of them. I prefer to use something that isn't laden with chemicals, is cruelty free and reef safe so this looked like it would fit the bill and indeed, it does. It is a true "no tears" formula which I very much appreciate. As with so many zinc based sunblocks there's still a slight "Kabuki mask" effect but it isn't as bad as some of the other zinc products. I wouldn't go so far as to say it's easy to spread because it doesn't have a lot of "slip", doesn't glide like the non-zinc products. You do have to work with it for awhile to get rid of the decidedly chalky consistency but once you get going it seems to be okay. I think somebody else mentioned using a moisturizer before you put it on which seems like good idea even though this is supposed to be moisturizing. Would I purchase this again? I'm pretty sure I will because the "no tears" aspect of the product is important to me. I'll probably use it with a light carrier oil on my face first, let that oil sink in and then put this on top. I'll keep you posted on how that works out. Thank you, Alba Botanica, for being cruelty free and reef safe!

Thank you for making this
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I have the most sensitive reactive skin. I regularly will breakout to products that are supposed to be hypoallergenic and non-clogging. I have used this product multiple times and have not had one issue. I also burn in literally 2 mins and I live in Las Vegas. This protected me and my skin did not react. It absorbed in like regularly lotion not leaving any white cast or sticky feeling. There was no scent which is SO important. I wore it only in the sun not swimming so I cannot comment on how well it works under those conditions. I will by this again without hesitation. If you are in need of a high quality sun protector and have skin like a baby or you are a baby this is the best.
