Pratique du Shadowing: How to determine your skin type | Dr. Jenny Liu - Apprendre l'anglais à l'oral avec la vidéo

Hey guys!

Today let's talk about skin type.

I mean we hear these terms thrown everywhere all the time like normal skin, dry skin, combination skin, oily skin, and sensitive skin.

And although these are categories that we frequently talk about, it's not the end-all be-all when it comes to skincare and taking care of your skin.

So let's talk about really what the definition of these skin types are, how to determine your skin type,

and really what relevance they should play and taking care of your skin and your skincare routine.

Hi, my name is Dr. Jenny Liu.

I'm a birth survivor dermatologist and welcome back to my YouTube channel.

If you enjoy learning about skincare related content, haircare related content, then I would love it if you can give this video a thumbs up and subscribe to my channel.

All right, skin types.

Now, this is something that really have become a cornerstone in skincare.

Nowadays, we see more and more products being marketed towards certain skin types.

But what I want you guys to walk away from this

video is number one aside from just understanding the differences between these skin types

But most importantly understand that these are supposed to be really helpful guides

They're not meant to box you in and also keep in mind that skin type.

There's no good or bad skin type They're all very unique

and different and there are pros and cons to all of them

and Also skin type can change with age with hormone with the season

and even medications that you take that may either temporarily

or permanently change your skin type so honestly

when it comes to skin type even though we kind of

generalize this is suitable for x skin type for y skin

type i think it's really just most helpful as a guide for you

when you're shopping for skincare products because nowadays there's

so many different type of products formulations

and textures it's just really meant to be a good starting point especially

if you feel overwhelmed if you kind of know your skin type

that is like a helpful start to picking out products

but again it's not a guarantee and it's not meant to really box you in

and also doesn't mean that like

if you have oily skin you can't use products formulated for dry skin

and vice versa you know you at the end of the day understand your skin best

and you just kind of have to use products that work well for your skin, the ones that you enjoy at the same time.

Starting off with normal skin type.

I actually do not like this term because I don't really know what the definition of normal skin type is.

Like what is normal?

All of us are unique.

I sometimes equate normal skin type to like neutral skin in the sense you're neither super dry

or super oily and don't have combination skin, don't have sensitive skin.

But I feel like most of us at baseline have some sort of mild skin can concern

that i mean

that really is why what propels us to use particular products right to address those concerns

but if you don't have a lot of concerns

and you don't feel like your skin is either dry

or oily then great you probably have a skin that can tolerate

and can use various different type of products

but this is one where it's like not really sure what

that means but if you feel like you have it great you can shop and try out various different products

So normal skin type, I'm going to just leave it at

that because I don't really feel like it truly exists

and I really don't have a good definition beyond what I just said.

Next is dry skin and this is a skin type where often your skin will feel tight

and taut but also at the same time look rough,

look flaky and with dry patches and often fine lines are more accentuated when your skin is dry.

Dry skin often is seen along with eczema because the two kind of run hand in hand.

What is happening with dry skin essentially at the heart of it is that there are certain enzymes,

protein, as well as lipids like ceramides are missing or

that is not as functional and we actually know

that there is a genetic basis behind this from studying eczema

that basically goes into forming that healthy and functional skin barrier

and thereby your skin doesn't have enough lipids to retain moisture and water.

And so dry skin tends to be dry and often dehydrated at the same time.

And common concerns associated with dry skin includes eczema, keratosis pilaris, and skin sensitivity.

Next is oily skin, where basically the skin produces excessive sebum.

The oil glands are more active.

This is more genetically based.

Often the skin will look shiny and greasy in areas common like forehead, nose and chin like the T-zone where we have more concentration of oil glands.

Now I do have to say oily skin is definitely more

subjective in the sense we don't have an objective way of measuring oily skin.

It's not like there is some sort of like a measuring tool where

if you produce X number of sebum you have oily skin.

Dry skin is more easily identifiable in the sense we see flaking, we see eczema patches, we see breakdown the skin barrier.

Oily skin certainly your skin can look shiny and greasy

but it is very much kind of up to interpretation in a sense one person may feel

that that shine and greasiness is normal

but the same amount of shiny greasiness to another person

that person may feel like their skin is oily

but overall in general oily skin tends to be not dry the fine lines

and wrinkles are not as accentuated their skin doesn't feel as readily dry

and tight in the sense where like your skin feels taut

but oily skin can still become dehydrated oil

and water are not quite the same and so

but this is again where it's just in general the t-zone air tends to be more shiny

and greasy and there may be

higher association with acne but acne you know formation is complex

and we can see acne in all skin types

but in general it can be more readily associated with oily skin next is combination skin

and like normal skin i find this to be somewhat confusing too in the sense the true definition is

that you are oily shiny in the t-zone

but dry on other places like the cheeks um this is

again very much up to interpretation you know i think many of us experience

that at baseline because many of us do have more oil glands in the t-zone

and produces more sebum and dryness on the cheeks

but the true definition of combination skin essentially is just

that you have a combination of oiliness and dryness

and the common locations are t-zone oily cheeks dry

and this is also a situation where sometimes finding skincare products if you have combination skin can be tricky.

It almost feels like you need to put on different types of products depending on the location of your face

100

and I would say of all the skin types, combination skin is probably one type

101

if you do feel like you have where you probably need to experiment with more different types of products

102

and formulations to really truly find one that you're happy with that works best on your skin.

103

Lastly is sensitive skin and this is often characterized by sometimes dry, rough feeling skin, skin feeling type,

104

but more commonly are bothered by the symptoms.

105

So tingling and burning sensation, hard time tolerating skincare products because products will often cause those discomfort,

106

the skin may often look red and you may feel flushed

107

and sensitive skin often is associated with rosacea it's like along

108

a spectrum now as far as like sensitive skin you can have a baseline sensitive skin like

109

that is your skin type

110

or you could have a period of time where your skin is sensitive

111

and that can occur with any skin type and

112

that often is due to changes of season changes of hormones

113

or even just overdoing it with skincare products which i find louder to be the more common.

114

Like you could have oily skin, but like say you put on like salicylic acid and retinol, tretinoin and all these actives at the same time,

115

your skin can definitely become sensitive.

116

And you know that you don't have that skin type

117

because it just occurs randomly and it's temporary and as long as you remove those triggers, your skin will kind of go back to what it normally is.

118

But people that do have sensitive skin at baseline often feel like their skin is more dry

119

because sensitive skin we do know there is actually increase in transepidermal water loss

120

and some sort of skin barrier defect that contributes to sensitive skin.

121

But it's beyond that.

122

We know that there is neurovascular components and even ion channels in skin

123

that triggers those sensitivity and that skin burning and staying sensation.

124

But often it's more dry and often will look red and flush.

125

And again, the most common sensation is that it'll often burn and sting with a lot of various different triggers.

126

All right, so now that you kind of have a basic understanding of skin type, again, they're meant to be a helpful guide

127

and not meant to box you in and also keep in mind

128

that many of us can have a combination of various different

129

skin types like I used to have combination skin now I feel like I have more dry

130

and combination skin my skin definitely changes depending on the season where I definitely am more dry in the winter

131

but more combination in the summertime

132

so it's not like I said the end-all-be-all there is a spectrum

133

and so it's really just meant to guide you now having said

134

that like how can you determine what your skin type is.

135

So the easiest is number one, take a gentle cleanser.

136

So common ones I recommend includes like La Roche-Posay gentle creamy cleanser, Cetaphil creamy cleanser, Cervi hydrating cleanser,

137

something that's not going to be aggressive at stripping your skin's natural oil.

138

You're going to wash your face with a gentle cleanser

139

and then you're going to pat your skin dry

140

and basically you're not going to put on any skincare products

141

and you're just going to wait and check back like 20-30 minutes later

142

and then an hour later and see what your skin is doing and feel how your skin feels.

143

So in general, if after washing your face with a gentle cleanser, like after 30 minutes to an hour, your skin immediately feels tight,

144

noticing itching, noticing dry flicking, then you more likely have dry skin.

145

Conversely, if after cleansing, after 30 minutes, you're noticing like a film of oil building up in particular like along the t-zone

146

that you more likely have oily skin

147

and then for combination skin it's again oiliness on the t-zone dryness on the cheeks

148

and then sensitive skin as i said earlier tends to be dry

149

but it's really just that the feeling that

150

that you always have like burning

151

and staying at baseline regardless of what you put on

152

and often that can be even triggered by environmental things like wind cold heat

153

and your skin often looks like flush and

154

that really i feel like is also very helpful aside from just like this simple test

155

and how your skin feels after cleansing

156

and then for combination skin it's again oiliness on the t-zone dryness on the cheeks

157

and then sensitive skin as i said earlier tends to be dry

158

but it's really just that the feeling that

159

that you always have like burning

160

and staying at baseline regardless of what you put on

161

and often that can be even triggered by environmental things like wind cold heat

162

and your skin often looks like flush and

163

that really I feel like is also very helpful aside from just like this simple test

164

and how your skin feels after cleansing.

165

Now I'm not going to share too many particular specific products

166

and if you guys want me to based on skin type comment below I'd be happy to

167

but I just really want to offer like an overall guidance on how to select products in particular moisturizers

168

and sunscreen for different skin types

169

because really at the end of the day I believe all

170

skin types needs a moisturizer to really support the skin moisture barrier to keep our skin barrier happy healthy

171

and functional it really kind of distills down to the formulation that's going to work best for your skin type

172

but at the end of the day this is just generalization

173

it's not a hard fast rule you play around with products

174

and you just figure out what works best for you now going Going back to like dry skin, often dry skin is gonna be better suited with creamier formulas.

175

So richer, more nourishing creams that contains a blend of hydrating ingredients along with occlusives

176

and emollients and lipids that are really going to help to seal in

177

that moisture and support and replenish the lipids that are often missing in dry skin.

178

So that way after using that type of formula, your skin is no longer going to feel as taut

179

and tight and also reduce the flaking and the roughness on the skin.

180

Conversely, for those with oily skin, often like a gel or gel cream is going to be better suited

181

because there's going to be less occlusives that is really going to make and feel heavy on your skin, maybe add like shininess or greasiness to your skin.

182

It's going to be heavier on water-based content that is going to help hydrate your skin, but just enough so that way your skin stays hydrated,

183

but not too much where it's going to add additional shine or greasiness to the skin.

184

And often these products are going to be more fast absorbing.

185

So feel better and look better when you have oily skin.

186

For combination skin, as I mentioned earlier, this is one area where you kind of have to play around with products to find what best fits you.

187

But often creams, oil-free creams, oil-free lotions, gel creams, I tend to find work best for combination skin.

188

And then lastly, for sensitive skin, because it tends to run more dry, creams are going to be better than gel creams.

189

Gel creams with the higher water content may sting and burn.

190

And sometimes products containing alcohol and fragrances will often sting and burn.

191

So this is where it's easier to say what to avoid than what to try.

192

And in general, for sensitive skin, you want to avoid products that contain alcohol,

193

essential oils, and common fragrances because those can often cause more burning and stinging sensation.

194

And similarly, for like sunscreen, if you have dry skin, majority of the time, I do not find sunscreens themselves to be moisturizing.

195

So this is where in the morning, you want to make sure you put on a good layer of moisturizer before your sunscreen.

196

You can even do moisturizer and then pick a sunscreen

197

that has like a moisturizer in it to add additional moisturization to your skin.

198

Conversely, for those with oily skin, you may want to pick sunscreens and moisturizers along the sun, you know, for that matter,

199

that have mattifying properties that's going to temporarily reduce shine

200

and the look of greasiness on the skin

201

and often these have like ingredients like silica

202

and powder that's gonna help to temporarily coat the oil glands to reduce that shine and oiliness.

203

And this is where you could probably go with just using sunscreen

204

or like a moisturizer and sunscreen in one depending on the formulation.

205

As far as sensitive skin, you know, we in general say mineral fragrance-free sunscreens, but it doesn't mean chemical filters are completely out of the picture for you.

206

I used a bunch of Korean fragrance-free chemical filters postpartum

207

when my skin was super sensitive

208

and I didn't have an issue This is where it's really

209

about testing it on your skin first before using it all over

210

And basically you want to use any product any new product

211

And test it on like behind your ears on your jawline

212

or inner arms for about a week before you apply it all over

213

And it's not a guarantee but that is a very easy

214

and relatively safe way of making sure that products don't react on your skin before you use it more liberally.

215

All right I hope you found this brief video very helpful.

216

It's more like an introduction.

217

I felt like it's time that I talk about it.

218

We see it everywhere and it's just one of those things where it's a guide

219

but really not meant in any way meant to restrict you

220

or box you in and

221

if you want me to take a deeper dive in recommending particular products

222

because I I didn't really talk about like serums and cleansers and retinoids, exfoliants, et cetera.

223

But if you do want me to do that in a lot more detailed video based on skin types, please let me know in the comments below.

224

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
