Dark pigmentation on forehead and cheeks
Hello everyone,
I'm a 38 year old male, and I want some help regarding dark pigmentation that has happened over my forehead as well as cheeks over the last few months.
Starting off with the left cheek (photo 1 & 3) I've had this pigmentation for quite some time and it seems to get a bit darker when I shave my beard. However, since the last few days, I've also noticed pigmentation on the upper part of my right cheek (photo 2). It's a bit lighter, but is visible in the mirror as compared to in photos.
Apart from that, I've also had pigmentation on the center part of my forehead (photo 4) over the past few months. It's mostly in the form of the letter T, and the skin just above the eyebrows seems to be of the regular tone.
Also, I've had a dark patch on the top left of my forehead (visible in photo 1), and I believe it's how the pigmentation started. I've visited two dermatologists for these. The first said it was PIH (Post Inflammatory Hyperpigmentation) but there was no injury to that area, and the second didn't really say much. Both dermatologists prescribed Tacrolimus ointment that didn't do much, and I discontinued using it after a week after reading it's not even effective for hyperpigmentation.
I would also like to mention that the last few months have been extremely stressful for me due to some personal reasons, and I've pretty much ignored my diet. I don't have a proper sleep cycle either, and usually sleep and wake up late.
Lastly, I had a full panel done recently and it came up with Vitamin B & D deficiency, and I've been taking supplements for those.
I've read about products like azelaic acid, tretinoin, kojic acid, and glycolic acid, but I really don't know how to use them and which products to go for. I've never paid attention to skin care, and just use basic face washes and face scrubs from brands like Himalaya. I did use some products (vitamin C serum, retinol, and barrier boost serum) from Dot & Key on and off in the past months, but have stopped using them.
Please help, I'd be grateful. Thank you!
