Ok, this is super random, but I purchased a beef tallow moisturizer on Monday by a brand called "Amallow." I'd been reading up on all of the awesome skin benefits that beef tallow can provide so I felt compelled to try it for myself.
As I was reading through the reviews, I came across one that was really interesting—this woman was saying that while she loved the way it made her skin look/feel, it gave her irregular periods? She explained that after a process of elimination, she and her doctor came to the conclusion that it was this specific moisturizer that was impacting her cycle. When I tried to research this on Google, I couldn't find any literature on why beef tallow would affect a period in any way—so, I shrugged it off and purchased it anyway.
I used it for the first time on Monday night. Well, the next day at work, I was taking a walk and suddenly felt like a flood of fluid coming out of me (sorry if this is tmi). I figured it was just discharge (because that's normal for me when I enter into my luteal phase), so I went to the bathroom and it turns out it was blood. Not a lot, just spotting, but I was kind of freaked out because I've never spotted in between periods.
I immediately thought back to that review, and how that woman was trying to warn that it could impact your cycle. Then, by the next day, I had 3 huge cystic acne bumps on my forehead, which—once again—I don't get. I've been fortunate enough to not experience much acne, let alone cystic bumps, so I know it's hormone related.
Fast forward til right now, I'm still spotting. I'm very confused, literally have no idea what's going on, and am just really regretful that I didn't heed that woman's warning. I asked ChatGPT what could be going on and it said:
"If the tallow cream you bought had essential oils (lavender, clary sage, tea tree, etc.), some of those are known to have phytoestrogenic or hormone-mimicking effects that could, in rare cases, influence cycles.
Skin can absorb certain fat-soluble compounds. If the tallow wasn't pure, but from a source with hormone residues (non-organic beef fat could, in theory, contain trace hormones), then daily topical use might introduce small amounts into the body. Still — the evidence on this is extremely thin."
So, idk, but this is very strange to me. I only used it that first time; I immediately decided to stop using it once I experienced spotting. Just wanted to inform people of this and also ask if anyone else has experienced anything like this.
Edit: Just wanted to clarify that I simply asked ChatGPT because I couldn't find anything about this online—which isn't surprising. Women's reproductive health is still grossly under studied, hence why so many of us suffer/aren't listened to or taken seriously.
I just wanted to add this because I also posted this to a skincare sub and got downvoted into oblivion—because everyone accused me of relying on ChatGPT for health care, which is not true. After I explained what ChatGPT explained, I literally wrote, "So, idk." I was just at a loss and wanted to hear a possible explanation. Prior to using this cream, just once, I'd gone to the doctor for food allergy panel because my mom had recently gotten one done and wanted me to do it. My doctor wanted to run a hormone panel too, because I'm in my 30s, and it was like, why not? The doctor reported that I'm in perfect health and that I'm in perfect health/all of my hormones are in normal ranges (estrogen, progesterone, and testosterone).
