Fragrance in Skincare | A Biochemist's Perspective

[@jillypepper_]

It’s also important to know that “unscented” is not the same as “fragrance free”... unscented products often have fragrance that counteract that natural scent of the product to make it more neutral!

[@helpfulnatural]

Yes. Unscented products usually have an ingredient referred to as a masking fragrance. It can still be irritating to skin. :)

Hyram says that 2 products have fragrance is okay but if it a lot then, you are increasing the risk of fragrance. Also, if you want to buy a new one, you can use the moisturizer for maybe ur legs or other part of ur body.

Thanks for the PSA at the end about wearing too much fragrance in public! :) I'm a severe asthmatic so fragrances can give me an asthma attack. I had an issue at work with a coworker uses fragrances everywhere (plug ins candles lysol etc...) and I unfortunately had to escalate it to HR because she refused to listen to both me and my supervisor. The HR woman came to see her about that and some other issues and I swear it was like the HR lady had bathed in a tub of perfume that morning -_- this was after I gave them a doctor's note about it and everything. Some people just do not get it.

[@jcjccmz]

[@AuntBethanys]

I agree that it isn’t a judgement thing or “this is better”: BUT As someone who worked in Pediatric research for a time, I’m hyper cautious about essential oils. As they have become more popular, we are seeing more issues. Starting to see them actually interfere with hormones ESPECIALLY in children. (And those with chronic health issues) (Mainly Tea Tree & Lavender). I also wonder about the cumulative effects: Until more research is done, I’m staying away so thank you for going truly fragrance free!! ♥️

[@girllionness5944]

This is interesting! I'm split on essential oils. I definitely don't use them on my face or ingest them but I sometimes use peppermint oil (which I know is pretty irritating to the skin) on my neck when I feel like my muscles are too tight but I'm thinking I should probably stay away from it

[@rhiannonh5202]

@@girllionness5944 if you still want to use the peppermint oil on your neck maybe do a light mix in a carrier oil so you get the benefits without any side effects (at least in my experience). My mum is an aromatherapist so she makes mine up now because I used to use it straight onto my temples and neck for headaches and tension and it's not as strong and cooling in a carrier oil but still does the job just as well :)

[@NLeeyana]

Wow I didnt know about the cumulative effects and hormones in children. I used to diffuse it around my kids even during my confinement days. I was told its fine and safe. 😑

[@AuntBethanys]

Nadia Leeyana as far as we know diffusing is still okay. It’s just topically and internally, that is concerning. But then again, we still don’t know future effects. 🤷‍♀️

[@rhiannonh5202]

@@AuntBethanys Totally agree! From the research I've done and that my mum has done we are comfortable using topically diluted in a carrier oil but I would NEVER use internally. The most I have ever done is wet a cotton tip with water and put some oil on it (not even a drop just what is on the cap of a bottle when you dab it) and put it where I've had a toothache before. Oils do not mix into water so really diluting within water makes no difference and people doing internal use are often not educated about essential oils at all; I find it extremely concerning. I choose to not buy from companies like young living and doterra that say they can be ingested because without proper data I think it is too risky and irresponsible for a company to claim this which ethically I aqm against.

When a product mentions lemon extract or any fruit extract oil as an active ingredient , is that the same as having the 'fragrance' essential oil? Or are those 2 different?

[@Hyram]

Neha M It depends on the fruit! For citrus extracts, yes. But avocado oil is non-irritating and healthy. I use Paula’s Choice as a holdup reference to know which is which :)

[@franameri6590]

Yes, i.e. grapefruit seed oil -- is that an essential oil? Or is it used as a preservative?

[@sarahbarlow1941]

Fran Ameri grape seed oil is a carrier oil like olive oil or coconut oil, etc. essential oils can be diluted into a carrier oil to be safer to use, as essential oils are very concentrated. Some carrier oils you can eat or cook with, some you can’t, but the main difference in how they’re made is carrier oils are made from the ingredient being pressed, where essential oils are distilled from botanical ingredients. Essential oils cannot be ingested, and if anyone tells you they can, don’t listen to them. I encourage you to do some researching on your own as well, in case I missed anything or got anything wrong.

[@franameri6590]

[@yikes7607]

Hello Kenna! Could you please do an entire video just about exfoliation? I have so many doubts. I stopped using my usual exfoliant since you pointed out how the physical particles can be too abrasive for sensitive skin, which in hindsight made sense because exfoliating always made my super-dry sensitive acne-prone skin very angry, getting inflamed and with more outbreaks. The problem is that I don't know anything about chemical exfoliants, nothing at all. I don't know what to do because over time I have damaged my skin with harsh products to control acne, it's why it's so dry and dehydrated on the surface. I need to exfoliate somehow, just don't know what with.

[@courtneyscott1690]

Hokuspokus if your skin is flaky looking, that is actually not dryness, you just need to exfoliate (excess of dead skin cells sitting on top of the surface due to excess oils... typically found around the nose (t-zone area) or places where acne occurs). But physical exfoliants should never be used on acne! Acne is considered broken skin and all physical exfoliants will do is pop open the pimple without you being able to see it, and then it will just spread the bacteria around and cause more acne. Chemical exfoliants are wonderful! I use the alcohol-free and dye-free toner from Clinique. That has acetyl glucosamine and salicylic acid (not near enough to treat acne, just enough to soothe irritation (redness) and help get rid of dead skin cells). Those are both amazing exfoliants! I don’t like the alcohol toners, but the 1.0 is amazing!! I would recommend going to your local Ulta or Sephora and getting a sample. Just make sure they don’t give you the one with alcohol. Also, I use an AHA face mask every week, those two things have helped my skin so much! I hope you give it a try and hope this helped! 😊

[@MicahRion]

I started out with a gentle chemical exfoliant and really enjoy it.

[@hostronic]

Try a lactic acid treatment. Lactic acid is a BHA which is pretty gentle for people just starting out with chemical exfoliants. The Ordinary has a lactic acid serum that is really good and it’s super affordable!! Definitely use the serum after cleanser and before moisturizer. Order of thin to thickest consistency is important when layering skincare products. Oils should always be used last. Hope this helps!! 😊

[@yikes7607]

I will definitely try that, thank you so much! Everyone following Kenna is so helpful, it's pretty amazing ❤

[@beckyc.5743]

Wow, Kenna. I had no idea fragrances could be so complicated. Thanks for your discussion! I had no idea that there were so many reasons for allergic reactions to essential oils.

Hey Kenna, totally off topic but do you mind doing a video discussing your opinion on toners?

[@JasminMiettunen]

Though you sound knowledgeable about essential oils, I think a lot of people with less information just feel safer without using any scents, especially on the face. It can be very tiring to go through every single ingredient and cross reference information. I have no interest in unnecessary synthetic fragrance in skincare, but I do enjoy essential oils and aromatherapy. I'm happy for the tips on how to use them safely, thank you for sharing the information. I really enjoyed hearing a reasonable, informed perspective. Speaking of, have you done a video about reasonable sun protection? It seems to be another divisive issue, and I don't find either extreme view very healthy mentally or physically. I'm struggling to find a good balance.

Hi Kenna! I just wanted to say don't worry about the comments too much. I understand your feelings regarding this, I used to write some stories on an artist site, and in the beginning I was soo happy when I saw that a few people clicked on it to read it, even happier when some left a comment, of course I replied right away. But later on, when thousands and thousands read them with hundreds of comments, suddenly it became a little tiring and I wanted to put off answering them. Not because I wasn't grateful, I loved them very much, but I just felt I wanted to give each of them the right reaction to let them know I truly care, not just writing 'thank youu!!' to everyone. But on the other hand, when too much time passed, it seemed awkward to reply. Vicious circle. So don't stress about it, don't feel pressured! We are just happy that we found your channel, even more so with the lots of great content, maybe we also express our thoughts in the comments, but please don't feel that you're expected to answer all of them! It's very nice of you though, I think we all appreciate that very much. :)

[@sharonbaker3007]

It’s interesting that you’re suggesting we become scent respectful and aware, given that like you also indicate that the perfume industry is so large and lucrative. I personally don’t wear it often, only occasionally...but there are many people that wear it every day. I don’t have a problem with it until it’s sprayed in my vicinity where air isn’t moving. I’ve had asthma attacks when people people spray it in enclosed areas. Also I find most popular scents, especially musk, quite revolting. At the same time, scents I do like, that are in my soaps for example, I really enjoy. Ideally, all products would be scent-free. Trying to get people to not use them in public would be much more challenging!!! And yes, a fascinating topic!

Hi Kenna! Love your videos! I’m a big fan. I just wanna run this by you as I’ve been very confused by this product. I have a Dermaveen hydrating facial moisturiser. In Australia, this moisturiser is even cheaper than Cerave. The Dermaveen moisturiser is marketed for dry, sensitive skin and is supposedly hypoallergenic, paraben and fragrance free. The ingredients I will list in order: Aqua, Caprylic/Capric Triglyceride, Cetearyl alcohol, Glycerin, Prunus Amygdalus Dulcis oil, Cetyl alcohol, Macadamia ternifolia seed oil, Sodium acrylate/sodium acryloyldimethyl taurate, Isohexadecane, Polysorbate 80, Betaglucan, Cetearyl glucoside, Pentylene glycol, Sodium lactate, Lactic acid, serine, Urea, Sorbitol, Sodium chloride, Allantoin, Rosa Moschata Seed Oil, Avena Sativa Kernel oat flour, phenoxyethanol, caprylyl glycol, triethanolamine, benzyl alcohol, sorbic acid, ammonium acryloyldimethyltaurate/VP copolymer, disodium EDTA, tocopheryl acetate, sorbitan oleate. I’m just wondering about all the oils in the product and if it really is ok to use this product. My skin is not that sensitive but I do have acne so I’d just like to know.

Another phenomenal video! I find the way these skincare and other beauty products are formulated to be fascinating. Can you do a video about the way shampoos and conditioners are formulated? It is impossible to completely rinse out shampoo and conditioners in the shower and I find my neck & arms/wrists irritated after showering with even lukewarm water (so it's not hot water that's making my arms and neck/chest red).

[@ems_h.eartnotes]

I used to have this problem especially with conditioners. I switched to sulphate and silicone free hair care a few years ago which solved the problem for me so that's maybe something to consider. Or if you can't change your products, only wash and condition your hair with your head tipped upside down in the shower and wrap your hair as soon as you finish to stop the excess diluted conditioner running down your back etc

[@jcjccmz]

@@ems_h.eartnotes Thanks! I don't have a problem with sulfates or silicones, so I think it's the fragrance. I have had to try: 1. rinsing my hair under the bathtub faucet and then immediately wrapping a towel over it (like you say); 2. replacing my showerhead for one with super-high pressure to try to really rinse out the conditioner, lol; 3. the only fragrance/sulfates-free shampoo & conditioner I could find -- Free & Clear -- which completely stripped my hair of color & moisture and left it feeling like pieces of wet straw (so horrible). The ONLY thing that has worked so far for me is: 4. slathering my neck/chest and arms/wrists with petrolatum/Vaseline before getting in the shower, and then I can use whatever color-safe shampoo & conditioner I like, usually a high-end/luxury brand. Obviously if anyone knows of a good/nice fragrance-free shampoo and conditioner (instead of something I now use to wash my yoga mat & my brushes, lol), it would be really appreciated!

[@ems_h.eartnotes]

@@jcjccmz gosh that really sounds like an ordeal. I enjoy Briogeo, Rahua, John Masters, also I can cope with Hask well. But if fragrance is the issue I don't think those would do.

Good video! Just as a point of clarification, Patchouli isn’t a resinoid. The plant is actually a herb in the same family as mint, sage and basil, it’s true that it’s absolute is less prone to oxidation than some other absolutes but this would apply more to the darker (and coincidentally less pure, which is to say it has picked up byproducts of less delicate extraction methods) varieties of the oil which are less susceptible to UV degradation and are considered to improve in odour with time. The purest forms of patchouli oil (things like molecular distillates) are very light in colour but are also more prone to UV degradation.

I would love to pick your brain on what happens when these ingredients you mentioned oxidize. I'm in chemistry right now, learning about Oxidation reactions myself so it'd be interesting to learn about something practical.

Thank you for sharing your videos, I love learning new things 💙

My Pixi products have fragrances but I love the products, and I don’t seem to react negatively to the fragrance so I’ll keep using them. I’ve got my routine locked lol

[@dallaspayne3357]

I read recently that fragrance can cause long term damage to skin cells, possible pigmentation issues (I think it can react to sunlight?) and also cause collagen loss - that's what scares me most! Is this true? So many opinions out there, I get confused when I start trying to wade through google and I'm looking forward to your deeper dives into the topic x

[@mariamaria0238]

Excellent content! Looking forward to more essential oils and fragrance topics! 😀

[@Piccianify]

I started watching you after the Jaclyn videos (which was also great btw) and the quality of your videos has improved a lot since! But yes, like someone said, you can just heart a few comments and respond to stuff that maybe multiple people have asked/has many likes so probably many want to know about or seem most relevant, it's fine if you can't respond to everything! We understand and won't feel left out 😊

[@bleuuberries]

I love and prefer scented products, but then again I never had an issue with fragrance. The only time I noticed some kind of irritation when using cosmetics is when the alcohol is between the first 5 ingredients.

[@beauty_enthusiast]

I hope you’ll consider a body cream that comes in the fragrance free and fragrance formula - it sounds lovely! Congrats on your skincare line!!

[@gastogether4ever]

Yes, dive into the inner workings of perfume! And I'm looking forward to your essential oil ones too!

[@meiltoo]

Yes! Pls make more video on fragrance. I’m sensitive to fragranced pdt and would like to know how it happens. Thanks.

[@angeliquerenteria7908]

Where is your sweater from? It’s so cute! Also, I see you cranking out them vids and working hard 😉

[@shiphappens8385]

Work Hard, Be Kind... You tell ‘em. Love all your words.

[@sherryg1838]

I’m very allergic to fragrance including essential oils. I even developed a reaction to my shampoo and conditioner. Now I can see why! Thanks for the detailed explanation. That’s awesome your line is now fragrance free!

[@logey-lynnloge9532]

Amen about wearing scents in public! I'm allergic to perfumes, not in the sense of rashes or hives or sneezing, but as in my airways shut down. Your strong perfumes and scents can literally kill me. Be mindful and respectful, you might have gone nose-blind to it and so you put on extra but I and many others honestly lose the ability to breathe! Allergies and asthma are no joke.

[@greerdurham8101]

Do you have any info on how certain foods or drinks affect the skin and acne and possibly make a video? Thank you for your channel! I can feel my brain growing and your videos make me so happy!

[@JReid-yl4ys]

Dr Dray was the one who got me aware of the danger of fragrances in skin products. Now, I’ve removed all fragrance including from my foundation, and I suspect it has improved my skin.

[@brittneyhafner759]

You should do a review on popular drug store face washes / masks!! Like biore, neutrogena, etc. I think that would be cool since a lot of us use things like that!! I love your videos:)

[@franameri6590]

Wonderful, informative, fascinating video!!! Loved it so much, and would love to hear more about fragrances!!! Would love if you could also talk about phthalates as well!!! P.S. I am excited that you removed fragrances from your products. I am much more inclined to use them now xo.

[@HeitorJardim]

I've learned so much with this video!!! Really looking forward an in-depth video about the fragrance chemistry, and about essential oils too!! Thanks for sharing this, hugs&kisses from Brazil ❤️❤️❤️

[@ioanatoacsen1503]

You're such a sweetheart!! I love your videos, they're always so informative, I think it's my favorite skincare channel. Keep up the good work! ❤️

[@chrissibeauty7604]

I would love to know your thoughts on the glow recipe pineapple-c brightening serum :)

[@moonafarms1621]

Kenna do you plan on creating an spf moisturizer?! LOVE your products! Can't wait to use them... ♡♡♡

[@TracyN67]

Kenna, I LOVE YOUR CHANNEL!!!!! 😂 Thank you so much! Yes, I’m extremely sensitive to fragrance, chemical scents, etc. I get an instant migraine to anything strong. And I can’t use any fragrance on my face. I can use not citrus on my body. I love Frankincense.

[@TheCdathomas]

CeraVe doesn’t have a bad smell to me? Am I the only one? Lol

[@hsinpinghuang7500]

I think it smells amazing lol

[@jillypepper_]

It smells like nothing to me?? Haha not bad or good

[@GaGaMonstur]

Same don’t notice anything

[@sarahmasai1211]

No, you are not. I got puzzled when she said Cerave cleansers don’t smell good. I think the reason she said that is because people’s noses are so spoiled by massive fragrance usage.

[@aiquesono]

same haha

[@Banana11128]

Very helpful especially that in eu the fragrance know to cause allergies have to be named along side the word fragrance as not all fragrance ingredients are irritates. This im guessing is why in eu hyperalegenic products can have fragrance
