What is Skin Chemistry? Why Do Perfumes Smell Different on Others? Perfume Science Collection Types

Now I know what it means when people say animals can smell fear. There is an actual scent that’s produced. That’s so fascinating!

The points made herein are critically important not only for detecting health conditions in loved ones, but also to understand how and why fragrances can smell soooo different from person to person and from phase to phase of the fragrance. Well done, Dr. Smith! 👍👍👍💖💖💖

This is the kind of content people should pay to consume honestly. Thanks for your perspective and being generous enough to share.

Sorry for all the comments Claire. I was always able to tell when my ex husband’s blood sugar was high. He gave off a weird fruity sweet smell.

Many moons ago I was a "perfume girl" at Macy's. My job included spritzing customers with the latest masterpiece of perfumery as they stepped off the escalator. Inevitability someone would recoil in horror and say, "Yuck! That smells terrible!" We were taught to respond with "Perhaps it does not suit Madam's chemistry" thereby taking blame off the perfume and placing blame solely on the customer's problematic chemistry. All with Madam being none the wiser. Also, a little correction if I may. Sweat doesn't make skin more acidic. Skin does not have a neutral ph. Skin is slightly acidic with a mean ph of 5. Sweat has a mean ph of roughly 6. So, closer to neutral on the ph scale than skin. Thank you for another enjoyable video! Cheers!

Claire: I am taken aback by the knowledge, research, writing, editing and thoroughly exhaustive inquiry into these issues that we’ve all wondered about but never taken the time to understand and share. Your channel is unique in all of our fragrance community because of the endless hours you spend to bring these topics to us using language we can understand. I don’t think I’m able to quite express my high opinion of your content. I guess “Holy sh*t! I’ve always wondered about this, but all the reading in the world wouldn’t have helped me to understand it the way you’ve presented it in this short and wonderful video!” will have to do. I genuflect in your general direction. ❤❤🤓

I've noticed from all of your perfume science videos that so much of our experiences with smells are tied to reproduction and ultimately sex. So primal of us. Lol. Thank you for sharing! I love learning from you!

I’ve found it interesting how different the same bottle of a unisex fragrance can smell on the different partners.

Back in october, I sprayed ariana grande’s cloud on my skin after seeing a friend using it. I hated the way it smelled on my skin at the time, but then sprayed it on my skin yesterday and I liked how it smelled on my skin It really goes to show how much my environment, mood, diet and water intake impacted how the perfume smells on my skin. I’m in a safe place with an abundance of food, both of which have increased my mood and I’m eating more fruit, drinking more water, exercising more which are all things I wasn’t doing while living with my mum as being in poverty and being in a dysfunctional home made me have a depressed mood, got anxious more often and had to skip meals and go hungry because there wasn’t enough money to make food last the month

I love these scent science videos! This may be a bit different from the subject of the video, but I suffer from chronic migraines and I've noticed this affects my sense of smell immensely. Some days I will be obsessed with a perfume, and other days the same perfume will be extremely nauseating. I've also noticed that traditional "skin scents" are actually quite strong to me, and a lot of times "beast mode" fragrances are usually way too strong and overwhelming. It's very difficult as someone who has recently become a perfume lover!

Body chemistry is so unique! I love your explanation 😊 That's why one fragrance smells different on different people 🤗

The amount of time you put into this video! 😮Utterly fascinating (esp the Parkinsonism + t shirt). I love it when you say “sexy time”😂😂 Also, the ONLY TWO times in my life when I hated perfumey scented things was when pregnant. And my husband said I smelled terrible when I had infants (was nursing and didn’t want to wear anything scented…even deodorants) . But my babies were always snuggling with me; I obviously exuded a scent they recognized even if repulsive to others. 🤣❤️

Dr. Claire the queen of perfume science!!🙌 I'm so here for this!!

I have dry skin. That’s probably why I overspray insanely 😅

Also, I'd love to hear your take on what makes a fragrance smell lactonic or creamy (not the same exact thing). Charlotte Ross made a video on this and it just inspired me to learn more since "creamy" is my favorite fragrance category.

This is a great video Claire! ❤ All of these make sense. You always have the best insights! ❤

Oh my goodness I love this video! I think a person’s health and genetic makeup would make the biggest impact in how a fragrance smells. Thank you for sharing your knowledge with us❤

This is so fascinating! Loved it, thank you!

Love this video Claire very insightful as always ❤️ I started reading more into this a few weeks ago and it's so interesting 😀 Thank you for sharing 😊

Fascinating and incredibly thorough!! Nice job, Claire!!!💗💗💗
