The molecule of adapalene is more "rigid". It has less flexibility to adapt and bind to the receptors. Tretinoin has lots of bounds that gives flexibility. It binds to more receptors, it is less selective. It has more side effects probably due this lower selectivity but science still doesn't know well the mechanism of action of tretinoin
Vit a derivatives are great! I have been using lrp rendermic r cream and avene physiolift night balm for acne and they work well especially lrp rendermic but both also helped a lot with my neck wrinkles/fold traces significantly which was a pleasant surprise 🥰😎👌👏
Could you please shed some light on studies showing retinoids killing meibomian cells and causing irreversible vision problems
:O what? I literally use retinol eye creams
@@dreamie9868 you probably have a weak form like retinal palmitate or something . And even then i will find it slightly concerning because drying has been seen . So if you have been using it for a long time may be try to minimise it and just do the maintenance. And even then know that there are risks especially for those who already suffer a dry eye problem .
Thanks for this question! I remember hearing that retinoids may cause some kind of eye damage. I just found this study which seems to link the damage you're referring to to *oral* retinoids, and also found it reversible. But I'd love to hear what you have to say on the subject dr idriss! www.ncbi.nlm.nih.gov/pmc/articles/PMC10287853/
Your skin is so beautiful!
oo damn just found out about this
I guess I'm more in the need for adapalene then.. but I was running out of mine and somehow the pharmacies around me dont have adapalene and I cba to order online so I just get tret instead.. ill get bact to it once I'm finish my current tret
Damn, she took a deep breath for that one. Lol, breathe Shereene. haha. Covid can't keep those lungs from working. Deep breath....blurt out information in 15 seconds...and...go!
Which is better if you want to remedy both aging and acne?
tret for both. my skin gets firmer and less acne, i still have comedones though. might need more time for that to resolve
If you've sensitive skin then first go with adapelene.
personally, I found tretinoin better on both counts. The main benefit of adapaline is that it’s less irritating so unless you have sensitive skin you may as well use tret since there’s more evidence supporting the anti-ageing effects. Just start slowly and build it up. If you’ve never used retinoids it could be worth using adapeline first, especially as it’s easier to get hold of, and if that gives you desired results just stick with it, if after the purging period you are still not seeing desired results, graduate to tretinoin.
Products work differently for different people but the biggest pitfalls I think skincare enthusiasts are falling into rn is overdoing it. As soon as I pared everything back my skin was much happier. Don’t use a million products at once, especially when you are starting out with retinoids.
If you start retinoids be especially careful to protect your skin from the sun!!
Thanks for sharing such amazing tips with us. Now, I know what to use for my skin. I need adalapene for my closed comedones. but, my dermat put me on adapalene only for 1 month then switched it to tretinoin. Didn't mention proper precautions for that. My skin got burned.
Can u make a video about aloe vera gel
Doc how do I deal with hormonal acne pimples? They keep showing up at the same place and spot treatments do not work
differin burns my face to much, it actually made my chest turn red spreading just from contact while sleepin in v-neck shirts.
Perfect!!😀
Thanks for your videos! What do you think of such things as microcurrent and photo and LED therapies?
I second this question!
do you recommend any vitamin supplements? so many supplements out there now for hair, skin, and nails and a lot seem gimmicky! Thank you for all the wisdom
The only effective ones will be what's derived from beef liver and the retinol within them. Look up videos on people taking beef liver supplements for examples but to battle serious acne you'll have to get a serious amount of vitamin a on par with ultra low dose accutane to be effective. Most vitamin a supps are complete bs because accutane/beef liver are some of the only bioavailable forms of vit a. If it comes from a vegetable you'll get next to nothing from it when it comes to vitamin a.
@@rejectsagainstreality1335 vitamin a is lipid soluble and builds over time, imo id stay away from supplements with vitamin a, or avoid taking multiple supps with vitamin a and keep track of how much your taking. Overdosing on vitamin A can negatively impact your health.
@@rejectsagainstreality1335 if beef was one of the only rare sources of vitamin A then all vegans and vegetarians would be deficient, which obviously just isn't true. Sounds like you made that entire comment up. 1cup of sweet potatoes, winter squash, or kale will easily provide 100% or more of your daily value of vitamin A from the sources I've looked up. Idk why everyone wants to desperately believe that beef is magically healthy when the obvious answer has always been to simply eat your veggies
@@tyronepapas6243 great points definitely and always talk with a doctor cause dependent upon genetics you could get hypervitaminosis. But from the studies I've read you'd need to generally get about 25000 ius of retinol for I think it was a year and a half to start showing symptoms in most people. My memory is fuzzy tho from years of research so talk with the doc lol
can you get tretinoin without a prescription
And if you have both?
Question. Can I do my skincare routine a few hours before bedtime? Thanks in advance
Please… could you tell us about La Roche-Posay Effaclar ultra-concentrated serum this one?
What if I have normal skin and want to prevent wrinkles in the future…. Which one should I use ? I’m 33 thank u
Can I interchanged them?
Can I use adaplelne once a week and tretninoin another time?
what about isotetronoin with adapalene? my dermatologist put me on alternate day isotetronoin and next day just adapalene on t zone
I have a lot of acne and blackheads etc but I stopped using adapalene and unseated I use tretinoin for the same reason is it okay?
Umm my doctor prescribed 0.05% of tretnoin to me and asked me to apply it everyday and Epiduo which has adapalene in t for spot treatment
Does adapalene also offer anti-aging benefits?
There’s very little data for adapalene in the setting of anti aging. It can improve dark spots and photo damage but there’s no studies on it for wrinkles and fine lines.
can you alternate adapalene one night with retinol (one like Shani darden retinol reform) another night? (if you have acne but also want anti-aging benefits?)
also adding to this question, just using tertenoine also has major results on acne right? or is adaplene more effective for acne?
Probably, i hear about using different actives alternatingly. Well technically adapalene and tretinoin are both vit a but they do have different strength and focus so you could look at them as two different actives
@@akankshakohli962 tretinoine was used for acne before! so yes it works very well!! adapalene is gentler so less potent than tret, because teens use it the most!
Tret works on acne as well as on wrinkles.
dr dray answers it in a video! it's useless to alternate retinoids, you won't get more effect, but you'll get more irritation for ... nothing 😅
@@kathleen5800 thank you!! :) do you remember which video?
I have been on adaplene plus Clindamycin band wagon and used 3 7 times tretinoin 0.025 percent but it caused me bigggg hurting pimples on my face where i don't get pimples usually now what should be the next step
Btw which body washes or soaps do you think is also suitable to use to wash your hair? What woulds you suggest doing if your hair is a little stiff from not using shampoo?
Why aren't you using shampoo?? ( if you aren't ,as the comment seems to tell so,correct me if I didn't get you)
@Enaksi Hello! I do use shampoos actually 😂😂😂 but seeing a lot of baby products doubling as a shampoo and shower gel just got me curious whether there was a fundamental difference in how they formulate these 2 (or 3) in 1 type of washes or if it's really just a marketting thing.
@Enakshi Also, I was getting curious because I wanted to streamline and minimize the number of products I use.
@@msk-qp6fn oh I understood, it is good to minimise number of products
❤️
Adapalene also does help with wrinkles as well though, right? I use it and I have acne, but I’ve noticed it has reduced my fine lines.
It would be help if you would talk SLOWLY
these kinds of videos have a time limit so she needs to speak quickly. I think she speaks more slowly in the longer vids on her channel :)
Talk slower
