Vitamin C – Why, How & When To Use – Serum Benefits. ✖ James Welsh

Hello everybody. Welcome back to my channel
where we talk about skincare, grooming, sometimes hair care. So if that sounds like your thing,
make sure you are subscribed, turn on the notification bell as well. Notifications can
be annoying, you don’t have to. A couple of days back I asked you guys what topics you
kind of really want to see when it comes to skincare. And there was an overwhelming amount
of people asking about vitamin C. I get this because it’s a very popular ingredient at
the moment. It’s a very popular topic and there’s so much information out there um,
especially on YouTube but it’s kind of confusing. So today I hope I can clear a few things up
so hopefully you don’t have to watch another video on vitamin C (laughs). So what is a
vitamin C first of all? So obviously it’s a vitamin C ingredient within skincare, or
ascorbic acid as it’s sometimes labeled. It really is an anti-aging ingredient primarily,
um mainly that you’ll find within serums and moisturisers but it has um, lots of other
good benefits as well, such as skin brightening and more we’ll go into in a minute.
It’s one of the most powerful antioxidants to protect your skin against environmental
factors, free radical damage, ageing, wrinkles, all that kind of stuff. So you can see kind
of why is a very popular ingredient ’cause it’s a good all-rounder. There are several
types of vitamin C that you’ll see on the market and labeled um, on your ingredients.
They all pretty much do the same thing, some are more potent than others, um some are better
for particular skin types. And it is worth noting that when it’s in its purest form,
say in the serum, when antioxidants are exposed to um, light and air too frequently they break
down, so they kind of like oxidise. So it’s best to keep these products in airtight packaging,
um, in a cupboard, in their boxes, keep them out of light.
So what are the benefits of vitamin C? Pretty much everything (laughs). Anything you want
it to do, it can pretty much do according to a lot of brands’ claims. There also are
varying opinions, especially between dermatologists. Um, dermatologists, bloggers, as well. Some
people think vitamin C is amazing, some people think it doesn’t do anything at all and that
we’re stupid for using it. Here are some of the main benefits that people claim vitamin
C gives. Um, and what I personally experienced as well from using vitamin C.
Vitamin C can fade hyper-pigmentation. This is a big one for me. So that’s the brown spots,
dark spots left over from acne, sun damage, scars, all that kind of stuff. Basically this
is because it can slow down melanin production. And melanin is what obviously makes your skin
that bit darker. So at least fading these dark spots and evening out your skin tone.
As I mentioned, it’s a very popular anti-aging ingredient and this because it can promote
collagen production. So obviously collagen is tied to the firmness of our skin, elasticity
of our skin as well. But as we get older, obviously the collagen production kind of
just gets a little bit lazy, it’s like I’m not doing that any more. So using vitamin
C can re boost that collagen production and make our skin feel a little lot tighter and
firmer. It can protect you against sun damage. So
sun damage is caused by free radicals. And obviously vitamin C is full of antioxidants,
so basically this um, kind of stops the free radicals in their track and renders them useless.
It can revers and prevent sun damage. It also reduces redness as well. So vitamin C is an
anti-inflammatory. So whether you got that redness from sun damage or maybe bad acne,
or you just, I don’t know, like a little bit like puffy and itch (laughs). Does anyone
ever get that? I get that sometimes. So yes, vitamin C can reduce the appearance of this
redness. And whilst vitamin C doesn’t really sound like a calming ingredient, it can be.
Kind of. So how we do use a vitamin C? Where do we
find it? So obviously one of the most popular ways is in a serum. Serums usually come in
the bottle, usually a glass bottle and they come with a little dropper, pipette I believe
it’s called. And this is because serums are highly concentrated. So, this is where you’ll
usually find vitamin C in its kind of, not purest form, but most potent form is within
a serum. It has a more of a treatment feel to it and it’s something you’d use like after
a toner and an essence before your moisturisers. And saying that moisturisers also contain
vitamin C. They’ve kind of been in moisturisers for ages but because it’s become such a popular
ingredient, um, and vitamin C is kind of a buzzword nowadays, um a lot of moisturisers
are advertising more that their products contain vitamin C. These moisturisers are usually
good for daily use, twice a day. Um, so the dosage of vitamin C, dosage I guess
we’re calling it um, of vitamin C um, isn’t as strong as maybe a serum. And in the moisturiser
kind of gives you that brightening effect of your skin as well. And obviously the anti-aging
benefits are in there so you’ll vitamin C in a lot of like um, anti-wrinkle creams.
They’re in a lot of exfoliators as well, especially peeling gels, but I don’t really see the point
in that. Like I don’t … there’s no benefit to that really I don’t think. No (laughs).
We’ll ignore exfoliators. And of course they’re in cleansers, and this gives you that brightening
effect as well. Also, it can have a soothing factor when it’s within a cleanser.
So who can use a vitamin C? When it comes to skin type, vitamin C is kind of good for
all skin types. Um, depending in what way it’s used and what kind of form of vitamin
C you are using. Vitamin C serums especially can have like a tingling, burning effect on
your skin. Not burning, but it’s very, it’s kind of warm so if you have very sensitive
skin or you don’t want your skin to feel like warm and hot for no real reason, you may want
to look for vitamin C, I’m going to have to read this ’cause I can’t pronounce it, um
magnesium ascorbyl phosphate. Science. This is the type of vitamin C that kind of avoids
that stinging sensation and is kind of good for irritated skin, sensitive skin.
So when can you use vitamin C? This really comes down to um, what kind of vitamin C product
you are using. For example, cleansers use every day, once twice a day, moisturisers,
same kind of thing. And it’s even in sunscreens now as well. You can use vitamin C in the
morning and at night. There is kind of counter-arguments for both as to why you wouldn’t want to use
it in the morning, why you wouldn’t want to use it at night. Again, everything with vitamin
C is kind of up in the air. But if you’re going to use it in the morning, you have to
use a strong factor SPF, which I feel is stupid. There’s no point. I don’t know it’s stupid.
And some people even recommend using a bit of vitamin C serum in the morning and the
evening. My personal opinion, I don’t see why you need to or want to do that. First
of all vitamin C feels very … doesn’t feel amazing on the skin so it’s not something
I personally would want to put on, then walk out in public with.
It also has a brightening effect. To begin with it makes you look very very shiny, like
overly shiny to the point where I wouldn’t want to go out because people would be staring
at me. So, and that’s another reason. I personally use this at night because the benefits that
you see from vitamin C are very long lasting, so you can use it in the evening, the benefits
will last all throughout the day until you use it again. Um, the shine, the brightness,
the instant kind of whoow that it gives you. I think maybe twice a day is over doing it.
Especially if you use other active ingredients which we’ll go into in a minute.
A lot of people say that using a vitamin C serum is good during the day ’cause it boosts
the benefits of your SPF, your sunscreen. But if you’re using a factor 50 PA plus plus
plus, you don’t really need it boosting ’cause it’s the highest you can get, so it seems
a bit redundant to me. I don’t, I really don’t think there’s any point. So yeah, let’s get
to the, the bit that everyone’s talking about at the moment, is what you can mix vitamin
C with and what you can’t. This is kind of important because this is
what initially put me off using vitamin C ’cause it makes it feel so complicated to
use and almost dangerous to use as well. It sounds like a chemical that’s going to react
instantly if you use it with the wrong thing. So an obvious one I think for everyone is
AHAs and BHAs. Kind of don’t use it together. It’s just the idea of it’s over exfoliating,
you don’t really need to use more than one active ingredients in your skincare routine
if any. So it’s a bit, you know, there’s no need to do that. So I usually do BHA, AHA
in the morning, if I’m going to use vitamin C in the evening.
Niacinamide, now it’s for that mixing this with vitamin C creates a new kind of um, chemical
nicot, nicotinic acid that leads to skin redness and irritation. However, this actually stems
from a very outdated study, like a lot of fear-mongering skincare things at the moment,
from the 1960s where they took unstable versions um, of each thing, so unstable niacinamide
and vitamin C and made them react together. You’re not going to have unstable versions
of these in cosmetics. Um, when they’re together in cosmetics they are stabilised and pretty
much absolutely fine to use together. It can actually have amazing benefits for your skin,
like um, all the anti-aging stuff. So firmness, wrinkles, brightness and dullness especially.
So this should really be in the do mix together section.
Also it’s said not to mix it with benzoyl peroxide. Again, another ……. this whole
bit here is like ‘eeehhhh’. Um, another ingredient that’s not really … there’s no real backing
it behind it other than a few opinions and studies if that makes sense, it’s that idea
again that mixing the two together renders both them useless.
Benzoyl peroxide is um, it is gross. Don’t use it anyway (laughs) … its in a lot of
medicated acne skincare, so what your doctors would prescribe you. What the doctors tried
to prescribe when I was younger. Not for me, very drying for me, so yeah. I would avoid
it. Safe to mix with vitamin C is vitamin E. Basically
just a shit load of good antioxidants on your skin, so yeah. You can mix more but I really
don’t feel you need to know this because you don’t need to be mixing all these things together
anyway. As far as like your skin goes, you need … like calm down on active ingredients.
I know they’re very popular at the moment and lots of people want to use them and get
the amazing benefits from them ’cause the benefits from active ingredients are incredible.
But you know, use one active ingredients in the morning, use one in the evening. There’s
no need to be mixing all this stuff together and going crazy. That’s my opinion anyway.
So here are my recommended vitamin C serums. As I mentioned I was kind of scared of using
… not scared, but put off by using these because of the all the dos and don’ts. And
the chemical experiments I thought would be going on on my face if I mix the wrong ingredients
together. I’ve tried a few but these are my favourites. So first is a Klairs Freshly Juiced
vitamin drops. This is a serum that rejuvenates the skin like vitamin C does. Very very good
for evening out your skin tone, adding calmness to the skin as well. This is extremely non-irritating.
As I mentioned a lot of vitamin C kind of has a stinging sensation on the skin. This
one, nothing whatsoever. It feels like a very nice, soothing serum, on my skin anyway. That’s
how I felt. Next up is the Ta Ta Tiam, Taime, Tia’m (laughs)
My Signature C Source. A very popular one um, but a very vitamin C serum. Like it smells
like money (laughs). You know what I mean? Like is, it’s like um, ooh, it’s got a metallic
smell to it. It gives you that warm sensation on your skin. Not that enjoyable to use but
the results of this product are pretty quick. This is infused with 20% of original pure
vitamin C, helps remove dead skin cells and blackheads for resilient skin. Improves the
skin elasticity and firmness, brightens dull skin and soothes irritated and sensitive skin.
As as for that last bit, I’m … that was the description the product, it’s not the
nicest feeling to begin with but yeah, the next day your skin does look nice and feel
quite good. And yes, very swift improvements with that one.
Um, I feel like I left something out but any questions for me, please leave them in the
description box down below. I’ll try and answer as much as possible. As always guys, this
is my personal experiences with the products. Definitely test it out for yourself. Do your
own research towards the benefits, you know pros and cons of using a vitamin C serum,
whatever you’re using and make sure it’s right for you.
But that is it from me now guys. Um, as aways leave more video ideas for me down below.
I only make videos for you so (laughs) I want to do something you’re interested in. But
that is it from me now guys. I will see you next time.

  14. Been binging on your videos for days. Absolutely love how your videos are so brutally honest, something we don't see with all the sponsorships going on with the skincare gurus. Keep up the incredible work, the YouTube community needs someone as fresh as you ! Xx

  19. Bro, Immediately when I started watching the video I could tell you just applied it because your skin is just glistening 👌🏿

  21. Sir can i use vitamin c serum on face without applying any moisturizer first
    Please do tell mee its too much confusing

  22. Hey today is day two of using dear klairs vit C drops and i do feel it warm on application. It doesnt tingle or irritate skin but i do feel that my skin looks a tone darker (slight redness all over hence mayb darker ) after applying it. Is that normal. It doesnt hurt or bother my skin in any way.

  23. If we are a new user for the Tiam vitamin C should we use mix it with toner, and should we use it every night? Can we use vitamin c every night?

  24. For people suffering with acne, what would you suggest instead of benzoyl peroxide? Currently, I double cleanse using an oil mixture first and then I use a 5 percent benzoyl wash and clindamycin solution for spot treatments.

  25. You didn't mention how it reacts with retinol, I just bought some Vichy vitamin C serum today and I can feel my face burning but I'm glad as at least I know its doing something! It feels quite strong so I would be worries to use with retinol.

  26. I drink vitamin C supplements and it does prevent acne breakouts and clears pigments plus it builds the immune system.

  27. Don't know if anyone will see this considering how old the video is, but in terms of mixing niacinamide and vitamin c, it should be totally fine BUT you should check the website's instructions/information on both products before doing so, as The Ordinary's niacinamide, for example, says specifically NOT to use in conjunction with vitamin c. TLDR: don't mix The Ordinary's niacinamide with vitamin c, its formulation is not meant to do this.

  28. Try this whole Vitamin C skin care set by Avon for only $39.99.


    Valued at $85, the set includes:
    • Anew Vitamin C Brightening Serum, 1 fl. o.z
    • Anew Vitamin C Antioxidant Lip Treatment, .13 oz. net wt.
    • Anew Vitamin C Warming Peel, 3.4 fl. oz

  29. If you see ascorbic acid in the ingredients list but not vitamin c, do not think they are the same.

    "Vitamins cannot be isolated from their complexes and still perform their specific life functions within the cells. When isolated into artificial commercial forms, like ascorbic acid, these purified synthetics act as drugs in the body. They are no longer vitamins, and to call them such is inaccurate.
