Let us turn our attention first to the debate. The previously mentioned thread has opinions on either side of the topic, both pro and against. Both have insightful and scientifically proven points that serve only to hinder resolution. From the thread, in the jizz-is-good-for-the-skin-camp:
When I've jizzed on my evil ex-girlfriends face (we were going out at the time don't worry) her skin was pretty soft afterwards. It's actually true. The same protein in cum is used in Pantene Pro-V shampoo.
Fascinating! The Ph.D. who is quoted above could not be reached for additional comment as the thread is quasi-anonymous and leaves no contact information. From the jizz-ins't-so-good camp, we have the following prose:
A female friend of mine got it in her head to use my cum as a facial moisturizer, so whenever she would blow me she'd ask me to cum in her hand. I'd blow a load, and she'd wipe it all over her face The problem was that there is a lot of testosterone in cum. and it made her break out. conclusion, Swallow it. use Clinique on your face.
Besides the affirmative and negatives on this topics, there are, of course, those who are in the debate only to help with what they have to offer and don't inaccessibly take to one side or the other:
no but I know wher you can get plenty of cum
It was definitely this form of back-and-forth that led the experts over at Vice magazine to take matters into their own hands (or their partner's, whatever). They selected two volunteers with the idea that they would go a month moisturizing their faces, one with semen, one with off the shelf moisturizer. The results speak for themselves: semen is not as great as the legend holds.
However nothing is made of the donor's diet. If the donor had been lacking in vitamin E, for example, then the spunk would most certainly not be as good as, say, Jergins. However, if the donor ate many carrots and other vitamin D-rich vegetables, then the man-lotion could be far superior to standard facial treatments.
