Do You Need to Worry About Blue Light? A Dermatologists Explains How it Affects Your Skin 

Underrated video, explains exactly what u need in 7 minutes, no bs, no crazy jargon. Thanks

Can you PLEASE PLEASE PLEASE do a video on how long mineral sunscreen is effective on the face? This whole "apply every 2 hours" even when working at a desk (not next to a window) situation seems so extreme. Is there a way to INVESTIGATE how effective a sunscreen still is after 8 hours of normal (non-active) wear? Thank you so much!

I've found my pigmentation on my face has increased dramatically in the last 2 years. I've barely been in the sun due to illness and have been mostly in bed. I've spent on average 8 hours a day in very close proximity to my tablet. I had no idea until very recently that blue light could make my pigmentation worse.

So I can keep being on my phone 24/7? 😂 happy Wednesday ❤️

Thanks for making a video about blue light! Edit: Would you consider making some videos about the following? -How to increase hair density. -How to reduce sebaceous filaments. Does facial steaming help? -In-office procedures that are worth it? Microneedling? -Foods/diet for healthy skin? Thank you!! I’ve gone to dermatologists before but I think all my questions overwhelm them in the time they have with me and other patients. Any help is greatly appreciated!

Thank you Dr. Ellis. Can you please do a video on the different types of acne and what works for each? I’ve been receiving treatment for hormonal acne my whole life and then just last month was told I have bacterial acne. One week on these new bacterial acne treatments and my skin has never been so clear. I’m so curious about the differences now.

Thank you so much for the great video, very informative. This deserves a million views.

Dr Ellis, thanks for the review! For BL protection I use two products by Avene: 1. Intense Protect SPF 50 plus (in reality that is 60 plus), 150 ml, for sensitive skin, for babies and adults, fragrance free, water resistant 120 min, fluid to lotion texture, contains new filter TriAsorB (trade name) which protects against UVB, UVA and BL up to 450 nm, it is patented by Avene, Pierre Fabre, it is yellow so in formula you can see Red 33 which minimize yellow color on skin ("nude"). Premium product, but because of new filter and its bioaction it stains clothing even before washing like tinted sunscreen. Because of staining I do not use it below face and ears. It contains only four filters and it is easily removed by any oily product at night. the texture is very stable and oily and although I have some rosacea, I did not experience any problem. 2. Mineral cream SPF 50 plus, 50 ml, intolerant skin, babies and adults, fragrance free, WR 80 min, creamy texture, contains a mix of small and large particles of titanium dioxide for UVB and UVA and well as white pigmentary titanium dioxide and a mix of two iron oxides. Taken together, theoretically, large particles of titanium dioxide, pigmenatary titanium and iron oxides could provide protection against BL. The product is not oily, so the skin needs to be clean, hydrated and moisturized either at night or in the morning to minimize drying effect. It is white on application but because of iron oxides it soon becomes lightly tinted. They also have Mineral lotion 100 ml with the same formula. In terms of staining they are not very reliable, so below face and ears I use other inorganic products. 3. According to Avene, one full finger is needed for face, ears and neck (front and back). I apply sunscreen only twice a day.

This is great! Ended up finding this video after CNET shared an article that said blue light emitted from devices can age you, which was absurd. Worst part is the studies listed in the article only mentioned 300-400 nanometers which is not visible light, and it didn’t mention how much exposure.

The MAIN concern with blue light is a dramatic rise in hormone sensitive cancers (essentially doubling the rate) caused by the intense high energy blue light exposure from LEDs. (Per Spanish study of ALAN and others). There are a dozen other major harms. LED lights are the major source. Another major impact is increased rates and severity of macular degeneration. The lack of red and infra-red is an equally large problem. And LED lights lack those.

Glad you touched on the evidence for oxidative damage

Can you make a video on the different types of wrinkles that may occur on the face especially the lower half? What can be done in office such as chemical peels, lasers and such? How affective are they and what are the cost. I know injections will keep them at bay, but what about getting rid of the superficial part on the top layers first? Thank you 😀 Thank you

Such great info! Does blue light from screens still negatively affect our eyesight? Or is that not really an issue either?

please talk about blue light treatment soon! and also seborreic keratosis thank you

Thanks Dr. Sam. You’re awesome! Free education.

She has a resembles of haylie biber.youre gorgeous tho❤️

“ya know.. all the sexy stuff” lmao i love dr. sam ellis

I always found this really interesting! Blue light was considered bad for aging and skin but then blue light LED is used to treat acne? Is it the same blue light?

I love this! Wearing tinted sunscreen around the house doesn't sound realistic - what are the alternatives if we're using our devices at night time?

Avene just released their new patent filter triasorb, first filter on the market to protect against HEV light and broadspectrum through uva 1/2.

What about sun pigmentation on skin? Is it possible to remove it? I’m very white but my arms and legs are very “brown”, can we make our skin tone uniform?

I don't have a TV so I've used my phone as a TV for the last 6 years or so. I have noticed that the whites of my eyes are turning yellow. Looks like I have a growth on the sclera. I initially thought that maybe it could be jaundice, but now I think it's just all that screen time. Are these publications on blue light funded by "big wireless?"

I bought a blue light blocker screen protector online :) I wonder if it was just a gimmick or if it does actually block out the blue light? :)

Thank you. How do you compare adapalene 0.3 gel to tretinoin 0.025? Do you think it is good to use both by alternate them on different day to get the anti aging benefit from tretinoin and acne benefit from adapalene? Help please

great video ! please could you do a video on over the counter retinols as here in the u.k you have to have a prescription from a dermatologist to get a retinol and to see a derm here you have to be refured by a doctor or pay private which costs a fortune so your opinion on over the counter retinols would be great !

Any updates on if blue light damages and ages the skin? Or if it simply can cause hyperpigmentation? Thanks!

Dr. Sam are you from the future? Haha This topic is so timely now with a famous gamer/streamer's skincare line that targets blue light. 🤯 Thank you so much for the in-depth explanation and tips. Really appreciate it. Have a nice day. 💚🤗

Great explanation thank you

Thanks so much! This was very informative! I have an odd question. I now use untinted sunscreen (md solar sciences mineral spf 50). I have tried lots of different tinted versions (sun bum, Australian gold, colorscience powder, md solar sciences tinted version) but I always get nauseous after applying the tinted version. I was thinking it is the iron oxide? I also get nauseous after taking multivitamins with iron in them. Is this something you see in your patients?

What about the "night mode" on devices? does it filter blue light?

Thank you for the video! Random question: Can “happy lights” that treat seasonal affective disorder potentially make melasma worse? I tried doing some research but didn’t see anything on it. I feel like maybe my melasma has darkened a touch since using, so now I’m wearing sunscreen with it just in case 👍

My dermatologist told me that i have nodulo cystic acne and said not to wear sunscreen because the sun rays are not a threat for my skin at the moment

Great info. Doc i am brown asian. I have melasma. Looking into buying omnilux face mask for wrinkles. Is the red light they use help reduce melasma?

I'm so confused! I've been reading a lot about HEV/general light spectrum and the effect it has on the skin because I've been thinking about doing IPL for acne, general redness of the skin and post-acne pigmentation treatment. IPL works with some of the blue light spectrum from what I saw in different sources. So, how is it that IPL is recommended as a pigment reduction and increase of collagen production type of treatment but also, it's said that blue light (which is supposed to be part of the visible light spectrum that goes into IPL) can cause aging of the skin by breaking down collagen and elastin, and it's supposed to worsen hiperpigmentation???

I am 60 and have dark spots on my face. Should i use a spf for dark spots or a spf to protect my skin with a product that protects against blue light. 😊

Don't be concerned with long term blue light. My hubby who never wears sunscreen or any anti aging anything has spent 30 years as an accountant and programer, in front of monitors, and has no pigmentation or skin damage at 50. He has the skin of a 20 yr old.

Hi would you suggest anything for severe dark circles aggregated by stress ?

Without knowing I have been protecting myself from HEV! 😂😂😂 yay me.

Good info! How about blue light products intended for acne? Do those worsen Melasma?

Hi, excellent presentation. I am a physician but never fully understood the significance of blue light. With sun exposure I develop blotchy dark hyperpigmentation on my arms and legs despite using sunscreen. Can you recommend a tinted mineral sunscreen for the body.? Are the formulations for the face adequate to use on the body? I have a light neutral skin tone; slightly olive but have had issues with melasma and body pigmentation. Thank You!

Very informative 😊

Hello, Does blue light really work on loss of pigmentation?

Hi dr ellis i was wondering how old you are❤️

Great video :)

You have very nice hair. What is your hair routine?

make more vids!!! 💕

sun bad tablets good? ok doc…

We'll see how long this video stays up. You say anything against what the govt is doing, tend to get in trouble for it! And now "they" are putting up blue lights everywhere (street lights, highways) which is sketchy.

👍👍👍

Conclusion: sun is bad but your phone and tablet are A-OK. 😅 laughable.

This advice is garbage. If you want an excellent opinion on this topic watch Dr Dray's video on blue light exposure.
