Anti Aging Tip  Anti Aging Ingredients You Should Never Mix

Anti Aging Tip Anti Aging Ingredients You Should Never Mix

Anti-aging ingredients you should NEVER
mix or layer. So that is the topic we are talking about today. So, if you haven’t
been to our channel, that’s-, we’ve been doing a whole series on anti-aging, and
if you have oily skin or Acne, we also have a playlist on that, as well as how
to take care of your eyelash extensions. So today we’re going to talk about:
Anti-aging ingredients that you should NEVER mix. So if you haven’t watched any
of my last videos, I’m always talking about the pH of products. And so we’re
going to talk about today not only the anti-aging ingredients that you should
never mix but also why you should not mix them. So stay tuned for that. And if
you stay on ’til later part of the video, I will actually be giving you a BONUS. So
stay with us because we are going to include a link that you guys can click
on to receive the ingredients list of what you should never combine on your
skin. So, I had mentioned before that I’m always talking about pH. So when a
cosmetic chemist or a team of cosmetic chemists get together to create a
product for a specific skincare line, they-, in an ideal world, they make it so
that it is pH compatible for the next product in their same skincare line.
However, the reality of our world is, is that, you will buy a cleanser from one
company, and then you’ll buy a cream from another company, and so you’re mix-and-matching. So a lot of times when I’m doing a skincare consultation, I will ask
the person, “So how are all these different products working for you?” And a
lot of times the client will say, “Well… I don’t really see a whole lot of
difference, to tell you the truth.” And a lot of times it could be because they’re
using products that neutralize the effects of the ingredients and the
products. And so what we do here is, we understand that not everybody can use
one single skincare line. So I try to get pH compatible products so even though
they may not be able to use all the same things
in the same skincare line, that they can use different products, but still their
pH works with every single product. Because when you mix these ingredients
together, the WORST that can happen is you’ll have dry, irritated, even have
breakouts, inflamed skin, or at BEST, neutralize the efficacy of the products
and you don’t see a whole lot of difference. And when you start talking
about the more expensive serums and eye creams, especially for anti-aging or for
Acne, you’re purchasing them for the quality of the ingredients and then the
efficacy of the product. So when you’re not seeing any differences in your skin,
you’re kind of wondering, okay, what is going on? So you want to make sure that
the pH is correct. Okay, but, before we get into the good and bad ingredients and
what you should mix and not mix, I would really love it if you could hit the
SUBSCRIBE button in the lower left hand corner, as well as hit the notification
bell, and of course give us a thumbs up so you can help support the channel so
that I know that these are topics that you guys are wanting. So please make sure
that you give us a thumbs up. Okay, so here we go. We’re going to jump right
into the ingredients of what to use and what not to use. So here are a few GOOD
combo’s that you can use on your skin. So the first one is Retinol and Glycerin.
Okay? Or if you’re using Retin-A, you can do Retin-A and Glycerin. And the reason
why is because Retinol is a very common anti-aging ingredient. And what it does
is it speeds up the skin cell turnover rate. So what happens when you start
using that, it can dry out the skin. So Glycerin, typically it’s a vegetable-based humectant and it draws moisture from the environment and draws it to
your skin and binds it to your skin. So when one is dehydrating your skin, the
other one is actually increasing your skin’s ability to hold in the moisture.
And the next one is Retinol and Hyaluronic Acid. So it’s kind of the same
thing. Retinol, again like I explained
before, it actually can dehydrate the skin, because it’s speeding up the skin cell
turnover rate, increasing that desquamation rate. And Hyaluronic Acid,
now Hyaluronic Acid typically is gel- based. And so that is a humectant as well,
and it can hold up to a thousand times its weight in water. And that is great
for people who tend to break out easier, because it’s not occlusive, and it is
water-based, and we make it in our own bodies. So no one can be allergic to
Hyaluronic Acid or nobody can break out with Hyaluronic Acid. The next one is
Vitamin C and Vitamin E. Those work great together. So Vitamin C is usually the
more common, the more well-known one. But the reason why they work synergistically
together is because, when the Vitamin C anti-oxidant neutralizes free radicals, it
needs to regenerate itself again to keep fighting that free radical. And that’s
when that Vitamin E steps in, it helps regeneri-, re-, re-energize that Vitamin C
to keep working. Now the next one is well- known with pretty savvy skincare
enthusiasts, and this is Vitamin C and Ferulic Acid. And if you can get
Vitamin C, Vitamin E WITH Ferulic Acid, it is even better. Now Ferulic Acid is
actually a plant-based anti-oxidant and it’s usually derived from rice bran oil.
And what Ferulic Acid does is, one, it stabilizes both the Vitamin C and
Vitamin E, because we all know that Vitamin C is highly oxidative. It breaks
down very quickly when exposed to air, heat, and/or light. So not only does it
stabilize it, but it act-, it actually doubles the photo-aging protection of
sunscreens. And, so that’s why it is a great combination. And this is also
another reason why rice powders work better than your typical translucent
powders. And we will be doing another video on that explaining why. Okay so
here is the list for ingredients that should NEVER mix. So the first one is
Vitamin C and AHA’s. So if you don’t want to, know what AHA’s are, they stand for:
Alpha Hydroxy Acids. And the most common well-known one is Glycolic Acid. Okay? So,
they don’t want you to mix the two together. Because, both of them can
irritate the skin together and make them ineffective, and for more sensitive types,
you’re looking at an acid and an acid together in the molecule, and that can be
irritating to some skin types. So the other one is Vitamin C and Retinol. And
again, for the same reason, both of these can be irritants both together on the
skin. So, because Retinol actually increases the skin cell turnover rate,
thins the skin, your skin may not be able to tolerate the Vitamin C because the
Lipid Barrier may be compromised. Okay so the next one is Retinol, AHA’s, and
Benzoyl Peroxide. So if you’re trying to fight aging, premature fine lines and
wrinkles, AND Acne, and you’re trying to target as many issues as possible,
please don’t do this. So, just don’t layer this on top of each other because your
skin can not only get really dry with Benzoyl Peroxide AND the Retinol, but now
you’re causing an irritation possibly with the AHA. So what you can do is,
you can use them on the same DAY, just don’t layer it on top of each other. So
for example: Let’s say you use your Benzoyl Peroxide during the morning time
and then you use your Retinol or your AHA in the evening. But usually if you’re
starting to combine these three, a lot of my clients will start to see a lot of
irritation, a lot of drying, a lot of inflamed skin. Okay
another one is AHA’s, there’s that AHA’s again, and Niacinamide. And Niacinamide is,
otherwise known as Vitamin B3, it’s also an anti-oxidant. Now because of the low pH
from the AHA’s, this can actually cause the Niacinamide
to turn into Nicotinic Acid, and so we don’t want that to happen, so you want to
avoid these two together. So if this is another instance where you are using two
different serums and you’re laying it on top of each other, you can use the two
different serums but use one during the day, and one during the evening. So option
two is, you can also, if you’re using a toner that balances out pH and actually
increases the efficacy of anti-aging ingredients, another thing that you can
do is you can first put the first serum directly onto dry skin. Wait about 10
minutes or so. So usually, I would probably do Vitamin C first, because it’s
more oxidative, so put that on directly on your skin, wait about 10 minutes. Feel
your skin. If your skin is nice and smooth, then you can do the toner, and
then when your face is completely saturated, you can apply the other serum
on there, and then wait, and then put on your night cream. And again, if you’re
doing a night cream, make sure it’s not Glycolic Acid that has any AHA’s in
them. So if you’re confused about what toner to use exactly with your serums, I
will add a link in the description below that actually helps hydrate your skin,
and it’s pH compatible with a lot of anti-aging ingredients, so you can check
that out. And if you can, if you would like to actually get a LIST of all the
anti-aging ingredients that you should NOT mix together, then there’ll be a link
below where you can get that, we will email that to you as well. And if you can
go ahead and go to the our comments and tell us what is your favorite anti-aging
product or service and why, and we’ll see you in the next video!

  • Singer Songwriting School

    Ive been fighting with my skin for the last year. I have cystic acne and ended up drying out my skin trying to fight it (and it didn't help anyway!) Now I use Retinol 3 times a week and hyaluronic acid and vitamins C and E daily. I use an organic coconut oil/tea tree oil cleanser. My fine lines have gotten better. My color in general is more even, but this cystic acne is driving me crazy! I've been using an antibiotic gel for the past few weeks, but I don't see any improvement yet. It's frustrating! Do you have any suggestions?

  • Victoria Nicole

  • Mark Gauvreau


  • Milena Trifonova

    Dear Christy, thank you so much for your detailed explanations. I've been watching your channel and I loved it so much. But could you help me with something – how do I understand what is the pH of all the products I use? I use foam cleanser, micellar water, serum, creams for eyes and face, glycolic acid face mask and other face masks. These products are all from different brands. How to understand what is the pH of each one of them?

  • Kevin John Ladaran

    Hi Christy! Is it okay to layer the retinol cream and collagen cream?

  • Jennifer Raymond

    I have to admit I use Retin-A and bit C together. I only use this combo a couple times a month. I am 51 and my skin is a lot tighter since I started doing this. Now granted I only do this no more than3-4x a month.

  • Ana Siqueira

    Lotion p50 is AHA and PHA with niacinimide. Exception?

  • Sheila Pendley

    Thank You!

  • Katherine Vesely

    I have a product and is vitamin c, e, and some vitamin a. If I understand correctly that is a bad mix?

  • Finn D Human

    Thank you very much. Though I very keen to each product's main ingredients, I'm not very much aware of these dos and donts in combining products. This will be very helpful to me since I have sensitive skin and should be very wary about combining products.

  • Olivia Everett

    In love with your channel! I'm only 19 so I'm trying to learn as much as I can so I can start early 😄 I hope I can forever look like I'm in my 20's like you!

  • Elena Martinez

    Thank for a super great information. :))

  • Zentson

    You can still combine Adapalene (retinoid) with benzoyl peroxide to combat acne. This method however is for those who are very familiar of using retinoid (about 6 months of consistent used) and can tolerate retinoid very well.

  • Ambreen Khan

    Can we use vitamin c and hyaluronic acid togather?

  • Julianaa Leyba

    Can Vitamin c serum be use before or after niacinimide?

  • Naturegirl121

    Could you please list the order of how to apply these products? I think that will help us better understand how to layer products and not knock out efficiency and not irritate the skin. Thank you

  • Queen Mercy

    I appreciate your channel!

  • Emma Harrop

    Is the retinol and vitamin C combination still correct? I ask because I have a 1% retinol from Paula's Choice which contains vitamins and C!!

  • Birgit Bauhaus
