[AMA] I'm Dr. Leslie Baumann - Let’s talk skincare, AI, and the future of personalized skincare routines!

21 Upvotes

Hi Reddit! 

TL;DR Dermatologist here to answer all of your skin care questions!

I’m Dr. Leslie Baumann, MD, FAAD. I’m a board-certified dermatologist, textbook author, educator, and researcher based in Miami Beach FL, USA.

In 1997,  founded the Cosmetic Dermatology division at the University of Miami, which was the first university center ever dedicated to cosmetic research in the US. My Cosmetic Dermatology textbook was the first on the subject. It's in many languages and is used by dermatologists to learn cosmetic procedures. I’ve also written a textbook on Cosmeceuticals and Cosmetic Ingredients (McGraw Hill 2015) and a New York Times bestselling book on skin care, The Skin Type Solution (Bantam Del 2006, 2007, 2010)

I have spent the last 20 years researching skin type, skin care products, and skin care routines. My research on skin care ingredients has been published in my monthly column Cosmeceutical Critique in Dermatology News. (I am getting the linked for you)

My latest paper, “AI-Guided Personalized Skin Care and Custom Routines”, was published in the Journal of Cosmetic Science. It discusses the science, testing, and research behind my clinically-validated skin type quiz, the 16 skin types, and designing a custom skin care routine for your skin type. The paper also discusses how I see AI shaping the future of skin care product recommendations and personalized skin care routines.

I’d love to chat with you all about skin care, dermatology, AI, the Baumann Skin Type System/the 16 Skin Types, and anything else to do with beauty and skin health!

You can ask me almost anything you like, with one exception: Please don’t ask me to diagnose you. My answers will be informational and educational, and are not intended as an alternative for medical care. Please also ask me one question at a time. I'm Gen X - so I get confused trying to navigate multiple questions in one comment. :)

If you’d like the best personalized skincare advice, it’ll be helpful if you know which of the 16 skin types you are. You can take the skin type quiz here

I look forward to answering your skin care questions!

Miscellaneous [Misc] This red bump appeared on my nose 3 months ago, how do I get rid of it? Spoiler

I noticed this red dot on my nose in the middle of January, at the time I thought it was just acne. Now it's April and it's still here. Is this worth a trip to the dermatologist or is there anything I can do to get rid of it? I use CeraVe cleanser on my face when I shower pretty much every day and CeraVe face lotion right afterwards. Thanks for your help!

Sun Care [Sun Care] I am DESPERATE. Can someone please help me find a Japanese or Korean sunscreen that might not break me out and has a texture similar to Skin1004 hylu-cica water fit serum and lives up to its SPF claims?

14 Upvotes

I am so upset. It makes my life so much worse. Every sunscreen I have ever tried has given me pimples. I am someone who has never struggled with acne until I started trying to protect my skin from the sun. It makes me feel like wrinkles when I'm older is a better alternative to horrible skin while I'm young. I wear a hat every day instead and it makes me sad that I will have to wear a hat and sunglasses every day for the rest of my life. Sometimes I cover my entire face. I want to be able to feel pretty or fix my hair or sit by a window without the shades closed.

I recently tried Skin1004 hylu-cica water fit serum and loved the texture because it doesn't have the greasy feeling of other sunscreens, but it gave me pimples after wearing it two days in a row and it broke my heart. Is that sunscreen waterproof? I am thinking if it is then I need one that is not waterproof or something to make it not so clogging.

I want to use tretinoin or something to clear up my acne from all the sunscreens, but I need to find a better sunscreen first, so that I don't do extra sun damage. Dermatologists are no help. I ask them if it is possible that I could never find one that works for me and all they say is "no. impossible. you MUST wear sunscreen." and then they sell me a new, expensive sunscreen that also gives me acne and then I hand over the co-pay feeling so angry at doctors and the world. I am so frustrated and defeated. It has been 5 years. I don't know how much more I can take. Should I give up?

TLDR: Sunscreen has made my skin worse rather than better. I love the texture of Skin1004 hylu-cica water fit serum, but it gives me acne. Can you recommend a Japanese or Korean sunscreen that lives up to its SPF claims? (maybe not waterproof? Would that help the acne?)

Acne [ACNE] How the hell do you get rid of dry acne prone skin??

4 Upvotes

Everything I’m reading online of how people cleared their acne/CC texture is through topicals and treatments that are all inherently drying. I’m talking tret, spiro, accutane, differin, frequency wands, niacinamide, etc. My skin is extremely sensitive and dry yet acne prone with CC and blackheads, which I don’t understand how my pores keep on getting clogged if my skin is barely moisturized. Yet if I moisturize more I full on breakout.

I tend to get flaking on my skin paired with dozens of little CC bumps that seem to only go away with completely drying out my skin. Yet after a few weeks of drying out my skin I get these red irritated patches of skin so I switch to a gentler routine and the bumps increase again. It’s like a hell loop i’m stuck in. Even the “gentle” Vanicream cleanser started drying out my skin within a couple weeks. Been to several derms but it seems like a waste of money at this point because everything they can prescribe is just going to dry out my skin to the point where it hurts to even open my mouth with how tight it is. Please I need help or advice!

I have eczema so maybe that affects it but I wear cerave moisturizer every day and an acne medication called adapalene.

The only time this is minimal is when I don’t shave for like 4 or 5 days but I hate having facial hair.

I'm tired of having acne and it's just ruined everything for me. My actual skin looks very tan but now my face looks dark and have uneven skin tone because of lots of acne breakout and it won't just stop. I started to have acne when i was 13 and now i'm 21 and it's just won't stop. I have oily and acne prone skin.

My routine is cleanser follows up with toner, serum and moisturizer and all of my product contain salicylic acid. And i exfoliate twice a week. At first it's helped me alot but starting from a week ago my face get really tan and dark. Even worse the breakout happens mostly at chin and forehead, sometimes breakout happens at the same place where old acne just healed. No matter how hard i try i can't rid of acne and whiteheads on my chin. My forehead getting more darker.

Do i need to see derm at this point ? Do you guys have any suggetions ?

Product Question [Product Question] Moisturizers similar to L'oreal Hydratotal 5 Ultraeven?

Upvotes

I've been obsessed with this moisturizer for several months now. At first I hated it because of the whitecast it left on my skin, but I eventually learned to use that to my advantage and make my skin look glowly and more lively.

Recently it was discontinued and I do not know of any other products like this one. One that I am considering is the Olay Moistuzier plus touch of foundation, but I am not very sure about it. Would anyone happen to know of any other moisturizers that give a whitecast to the skin similar to this one?

Thanks!

PSA Cold Sore [PSA] [Personal]

54 Upvotes

I've had HSV-1 / cold sores for most of my life and get recurring outbreaks every few months. I've had a LOT of experience dealing with them and I wanted to make this post to share what I've learned with anyone who is dealing with cold sores. While cold sores are a very common occurrence (as many as 1 in 2 adults have oral herpes), they can be painful, frustrating, and even make you want to hide yourself away from the world. Here are some tips that can help:

  1. Valacyclovir (Valtrex): prescription antiviral drug. This is the most important tip, the FIRST line of defense. If you do nothing else, do this. It will stop a cold sore in its tracks. Without this, my cold sores keep getting bigger for 2-3 days until they're impossible to hide or cover with a patch. I take 2 doses of 2g taken 12 hours apart, first dose taken at the very first sign of tingling. When I do this, the sore stays very small and the healing period (from tingling to blisters to scab) is much, much shorter.
  2. Mederma Cold Sore Discreet Healing Patch: while you can probably use any hydrocolloid patch, and may want to if your sores are very small, these are what I use because they are made specifically for cold sores, cover a large area, and are extremely thin and barely visible. There is a lot of mixed advice out there about whether to keep cold sores moist or dry - keep them moist. Drying the cold sore out (with alcohol or what have you) during the blister stage might get you to the scab stage sooner, which some people prefer because they'd rather have a scab than an oozy sore, BUT then you have a scab for longer or risk scarring. There's a lot of evidence to support moist wound healing (and a cold sore is really just an open wound once the blisters pop), hence why hydrocolloid bandages even exist, and moist wounds have been shown to heal faster and result in less scarring. I have a small amount of scarring on my lip from decades of getting cold sores in the same exact spot and I don't want more. I start using the patches as soon as I notice the sore, and keep using them (changing every 12 hours) day and night until the sore is completely healed. Not only do the patches speed up the healing process significantly, they keep the sore covered, making it less unsightly and reducing the risk of spread. There's less pain and irritation because the sore never dries out or gets crusty or scabs. The only thing is that the patch may start to come off when you're eating. If I'm at home, I'll probably just smooth the edge of the patch back down once I'm done eating, but if your sore is in a spot such that eating with the patch on isn't possible or you'd prefer to take the patch off while eating, then just make sure you apply a bit of Aquaphor or your preferred lip moisturizer to keep the sore moist as you eat, and then reapply a new patch once you're done eating to your clean, dry sore. I usually use a little bit of moistened paper towel or tp to gently dab at the sore to clean it in between patches. Don't shower with the patches on, try to time showering with the changing of the patches, or if you must, avoid getting the patch wet.
  3. Whatever lip ointment you're using, make sure you're applying that with a Q-tip or applying with clean hands and washing them thoroughly after touching the sore. Always always wash your hands after touching your cold sore, it's super important, you don't want to risk spreading the cold sore to some other part of your body or to someone else. Don't use chapstick directly on the cold sore, because the herpes virus can live on surfaces and can spread from the chapstick to other areas of your lip. For this reason, squeeze-tube or jar lip ointment is preferable.

That's it! IMO don't waste your money on topical treatments (Abreva, etc.), they are expensive and don't work well. Valacyclovir and Mederma patches are somewhat costly, but they're extremely effective and well worth it IMO. Anything that shortens the time in which I have a cold sore or makes me more comfortable/confident is money well spent for me. When I take valacyclovir at the first sign of a cold sore and use the patches day and night, I can get from angry, itchy sore to looks-like-nothing-was-ever-there in a week. BTW the scab is still part of the healing stage and you're not fully in the clear from transmitting the virus to someone else until that scab is completely gone and it looks like nothing was ever there. That's why I think this method is best because it gets you healed up the fastest.

Hopefully this helps someone!

Small cluster of bumps showed up a couple days ago, I usually have decently clear skin. It’s a stinging burning feeling if I move my nose at all. No new face products.

Miscellaneous [MISC] Had local anesthesia for dental work—now dealing with weird skin reaction. Anyone else experienced this? Spoiler

Post image
Upvotes

For a disclaimer I am 24 yrs old female recently had my teeth deep cleaned and filling. The dentist injected local anesthesia in my gums and the whole procedure was painless. After few hours of procedure i started having itchiness around the side of my cheeks where the procedure was done and not long after my whole face started to flare up with these red bumps and itching everywhere. I did talk with my provider and she suggested to take antihistamine which did helped for itching but not the bumps all around my face. I also changed my moisturizer not too long before my procedure but it was okay until after procedure. I am so confused about how it happened cause i had lidocaine before without any of these concerns. If anyone has been through same thing or know what i should be doing please let me know. I am so worried to even go out of my house.

Acne [Acne] Breaking out every time I wear makeup

Upvotes

I break out into new pimples every single time I wear makeup. I don’t sleep in my makeup and I double cleanse/ use micellar water. I don’t supposed dirty brushes/sponges could cause you to break out every single time? I feel like even if I clean my sponges it doesn’t make a difference because for as long as I can remember I break out every single time. I rarely wear a full face of makeup anymore but last week I went out twice with a full face and broke out into new pimples each time! I’m talking white pustule, white heads and regular red pimples. It’s not a crazy break out but bad enough. I’ll be grateful for any advice/insight I can get 🙏🏼

Product Question Are rice cleansers good for brightening glassy skin? [Product Question]

Upvotes

The rice skincare trend seems to be making a comeback, but it’s actually always been around in Korea. Traditionally, people believed rice made your skin whiter…..💀 

but nowadays it’s more about brightening dull skin by gently removing sebum and dead skin. It also supports the skin barrier with probiotics and microbiomes. So in the end, it all correlates to the same thing because when your skin is exfoliated and healthy it naturally looks clearer and more radiant

I’ve tried a few rice cleansers and I’m looking to discover more... currently eyeing ones from The Face Shop, Tatcha, and Beauty of Joseon 👀 I’m mainly looking for gentle exfoliation and a finish that doesn’t feel drying.

and here’s what I’ve used so far:

Veilment Rice Artemisia Foam Cleanser: Really affordable and works well. It combines rice with Korean artemisia, which helps with hyperpigmentation. It’s a clear gel type, not very foamy, but leaves a moisturizing finish that’s perfect for a morning wash (I have combination skin)

Arencia Mochi Cleanser: This one went viral in both the US and Korea and kind of kicked off the mochi cleanser trend? It’s a bit thick for daily use, but works great as a face mask and cleanser combo—similar to the Fully Green Tomato Cleanser. I usually use it once a week when I want a deep cleanse

9 Wishes Rice Foaming Cleanser: One of my favorite underrated finds from Olive Young. Their rice cleanser and hyaluronic acid ampoule really helped clear up my comedonal acne. The cleanser uses fermented rice and rice powder, and the texture gently exfoliates as you rub it in. Leaves the skin feeling soft and smooth

Would love to hear any other rice skincare recommendations, especially if they help with brightening and barrier care !!
