you're actually a demon no oh sorry mom

hey guys it's dr daniel sugai board certified dermatologist welcome to my channel i'm a medical surgical

and cosmetic dermatologist in seattle washington

and today we're going to talk about a very common question

how do i work on my stretch marks the medical term for stretch marks is stria

and we all love the wildly popular netflix movie k -pop demon hunters great music the songs are all

so catchy the patterns of a demon though the kids got

it mixed up with mom's stretch marks stretch marks very very normal i just wanted to say

that i want to put that out there

that stretch marks during puberty as we have rapid growth around

the hip girdle the thigh buttocks area very common to get stretch marks there at any point of your life

but we started seeing them in puberty

and also in times of rapid weight gain like pregnancy other

causes of stretch marks would be using topical steroids overusing them

and not taking breaks always talk to your dermatologist on how to use topical steroids appropriately because

if you use it too much especially in the folds the armpits around the elbows behind the knees

you can develop stretch marks as well for stria

and other conditions would be you know endocrine disorders like cushing's

disease being on chronic steroids taking exogenous prednisone long term for those with autoimmune disease for example

so there are different types of stria there's red stria

and white stria the white stria are very tricky you have a depressed look to them

and they can be a lot less pigmented than your normal skin tone.

Now the red stria can also be very bothersome and very pronounced red or stria rubra.

If you are treating stria rubra, there are different ways to go at it.

There's topical retinoids like tretinoin.

So you see a dermatologist for topical retinoids like tretinoin or tizaratine.

There are studies to show that it can help with stria.

I would use it for both red and white stria.

Red stria though, because there might be a vascular component involved, I would say pulse dye laser is a good option for

that that's a v -beam

or vascular laser where we're targeting the hemoglobin your blood vessels to treat them

and then using a retinoid as well only thing for retinoids though

if you're pregnant you can't use a retinoid oral retinoids like isotretinoin has been associated with birth defects

so it's definitely class x

when we use the pregnancy classifications back in the day

it has always been traditionally considered x means teratogenic do not use

that during pregnancy

so same for topical retinoids even though a small amount might be going systemically

we say don't use any topical retinoids even retinol over the counter

if you're not pregnant if you don't have access to dermatologists retinol is less potent than trepinoin

and may help with your stretch marks or stria so

if you wanted something

that you could spread very easily

you can do a retinol body lotion like versed naturium coco kind

they have nice retinol body topicals the coco kind retinol body cream i've been using more recently

and i love the texture of that the others are lotions those are nice

and spreadable if you wanted to use rock fragrance free retinol you could consider

that as well that that's the same cream

that you would use for your face you would apply

it down to the areas where you want to treat them now things don't happen overnight

if you're using a retinoid always say it takes about six

or more months to start working on the collagen

and that's what we're really trying to target is trying to restructure the collagen

and help strengthen the skin have increased elasticity

and less fine lines of wrinkles

and also trying to help with the stria as well

because what we're having are micro tears in your skin especially down in the dermis

so we have to repair that and increase collagen production

if you want to use a peptide containing moisturizer we don't have any studies behind

that for helping with stria but i can imagine it helping

or doing something for our collagen so say for example using neutrogena's collagen bank moisturizer

if you want to use the os1 peptide containing creams by one skin

they have a body moisturizer you can consider that

and finally i want to talk about for stria in general

i don't think vitamin e works well the data behind that's very inconsistent cocoa butter

and other you know topicals that promise

that it could work for you i've had patients who brought in sketchy creams into my clinic

that could help with milia or cellulite or stria and

if you look at the packaging on the label the ingredients aren't well laid out

and if they do have an ingredient list there's a lot of misspellings.

directions have grammatical errors i don't know where these creams are coming from

so be very careful and i've had patients come in

and bring these creams that are from unknown brands

and they're coming in with a bad contact dermatitis either allergic

or just irritant contact dermatitis where the skin is irritated by the ingredients in the product

or they have a true allergy which presents with redness swelling blisters

so be on the lookout for those sketchy products and stay away

if you just have a bad feeling if it's promising the results

that are just really sounds too good to be true it's probably not true okay

so just be careful for those products online the other ingredient

i want to talk about finally in this video is centella asiatica

now that's also known as tiger grass we see this a lot in asian beauty products especially k -beauty products

and i've talked about a few on the channel

so centella asiatica extract you will see in some products

i've liked i've talked about on the channel with the madagascar centella hydrating serum by skin 1004 very nice brand

i feel like it was really nice hydrating my skin

if you want to put

that say on your stretch marks on your abdomen on your thighs

and then cover with a peptide moisturizer i think that's a really nice call there

because centella has been shown to increase collagen production increase fibroblast proliferation

and help with tensile strength and might help strengthen

that dermis where we're having those micro tears from rapid weight gain genetics

it's probably not going to reverse things a hundred percent but

if you want to do things preventatively or

if you have after pregnancy you want to work on a nice postpartum routine

you could throw in a hydrating serum with centella

or having a centella cream like dr dark cica cream those are you know great products

i've liked the green tinted sunscreen for the face

but they also have just a nice cica cream for the face

100

and you can also apply

101

it to the body madocastaside is within centella asiatica extract madocastaside is just one of the ingredients within the extract

102

and they've isolated that down but there's no good studies on

103

that showing that it works on stria itself but

104

because madocastaside is known to work on wound healing work on collagen i would say i can actually suspect

105

that it might help and so using something like la roche -posay cecoplast balm

106

that i have patients use post -operatively on their surgical scars i would say probably a good bet

107

and using as a moisturizer for your body for stretch marks we need large scale studies to show

108

that even centella asiatica extract itself works really well

109

but there are some studies that show the extract works on stria

110

and we need to look and see

111

if isolated matocastaside itself can help with stretch marks that'd be really interesting for devices

112

if you want to work on red stria there's

113

that pulse dye laser for depressed white stria you can consider radio frequency microneedling with a trained specialist

114

and trying to really break deliver heat down deep into the dermis to try

115

and rebuild that collagen structure you can consider also resurfacing lasers

116

but all with varying degrees of success rates

117

and also depends on the operator of the laser or the device

118

so do your homework well before going to a clinic

119

if you want to get any kind of procedures done with

120

the device please hit the like button guys thank you

121

so much for tuning in every saturday please subscribe to the channel

122

and hit that bell notification and share this video with friends who are into skincare

123

and drop some comments on products that you feel like have helped with your stria

124

or stretch marks there's no product out there

125

that will fully reverse your stretch marks

126

and a lot of times we can't prevent it i just never want

127

you to feel badly of your stretch marks because it is common

128

and very natural skin finding okay

129

so never feel badly about it including cellulite guys that's very very common

130

and even though there's no really good devices

131

or topicals for reversing cellulite don't feel badly about them all right love you all guys thank you

132

so much for your support peace

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
