Question about Vitamin C and Hyaluronic Acid Serums

Started 1325618552.37 in Beauty Banter | Last reply 1326150613.837 by mayjak

I recently incorporated a Vitamin C serum (Devita) into my routine and know I should wait 20 minutes before going on to the next step. I also use a water-based HA serum. I haven't been able to find out if I can mix the two serums together in my hand or if I have to wait the 20 minutes after the C before applying the HA serum. Used together, the C doesn't sting, and I feel like I'm getting better coverage because it's easier to spread. If I use them together, I then wait the 20 minutes before applying my SPF moisturizer.

My question is: Can I mix the two serums together or am I diluting the benefits of the Vitamin C by mixing it with the HA serum?

I am looking forward to the replies on this one because I just received my DeVita Vitamin C serum over the weekend and started using it. I haven't been waiting 20 minutes before proceeding with the next step, I didn't know we were supposed to. I thought I read somewhere that if the products are formulated correctly and with the proper PH, you shouldn't have to wait in between applications.

Why do you need to wait 20 minutes before applying the next step? I don't see any mention of waiting on the Devita website and have never seen a vitamin c serum that instructed waiting 20 minutes.

You can mix the 2 together, although that will probably raise the pH, which can make the vitamin c serum weaker and less effective. That's why it doesn't sting as much when you use both together, vitamin c is more effective at an acidic pH, the HA serum is more neutral. However, if you have senstiive skin, mixing with the HA serum may help your skin to tolerate the vitamin c better if you are having a lot of stinging and irritation.

cassiem - I've seen the waiting time on various forums, but they are not always reliable sources of information. If I layer first the C and then the HA without waiting, is that any different than mixing them together? I appreciate any further info you can provide.

i use the Devita C and Solar 30 sunscreen, and dont wait 20 minutes in between

the C serum sinks in immediately and I believe from what I have read it goes to work immediately.

I probably wouldnt mix the 2 so that the C isnt diluted, and can be used for what it is needed to do - protect and defend :)

Also I agree with our highly respected Cassiem - always seems to be spot on in her analysis of products.

HTH :)

The NeoCell Collagen + C serum I use has liposome technology...it sinks immediately into the skin. I never think twice about applying the hyaluronic acid serum over it.

I use philosophy Vit C booster and used to mix it with their WHISNE face firming serum and now mix it with other serums I use. I've noticed no difference in the effect or tingling by mixing. I did notice that it oxidized my foundation to a lovely orange after a few hours{#emotions_dlg.blink}. After reading up on it I learned that it rapidly oxidizes when exposed to air and light--and oxidized Vit C actually increases free radical production so now I only use it at night.

Where did you order your Devita C?

Really great question, Mayjak.

I ordered my Devita Vitamin C from Vitacost, which is where I usually get my Devita Solar SPF 30. When my order came, Vitacost had sent me the wrong Devita product. When I called, they said to keep it and immediately sent out the correct C product. That was great customer service.

I really like mixing the two serums (C and HA) together, but I won't do it if it makes the Vitamin C less effective.

Probably the same person that told her to buy it, told her to wait.

If you apply the c first and then HA over it without waiting, the c will still be active because it's absorbed into the skin and begins working right away. Mixing them together may make the c a bit less active (although I can't say for sure, I don't know the pH of either product, but I think in this case it does since you say the HA diminishes the tingling). However, you can experiment because a you could still see results with a less potent vitamin c, it really depends on your skin. It's really up to you and what you want to try. You could your face half and half each way to see if there is any noticeable difference. :)

Bella, I purchased mine from Amazon because I'm a Prime member and get free shipping, but I also spent some time on their website looking through other products of interest, and you can get it there:

I've only just started using it, but love how my face feels upon application. It absorbs quickly. Some others I've used have felt sticky and I've waited upwards of an hour before applying my next product.

Is the hyaluronic acid serum by NeoCell as well?

Thank you

Are all hyaluronic serums basically the same or are there certain brands that are better to purchase?

I would never have that much time to wait - so I always choose multi-tasking products. I would think that as long as one serum absorbs you can apply the other one. I found that generally serums absorb almost instantly (max 1-2 min). If they do not, then they are either too thick or you are using too much... Maybe I am wrong...

Edit - I saw you said the C serum doesn't sting if you mix it with the HA one. A vitamin C serum should not sting!! That is why serums that contain potent actives like glycolic acid or retinol or vitamin c should have soothing ingredients to counteract possible stinging. That is why serums should be a cocktail of beneficial things so you do not need to use three serums to get the benefit of three types of things. Again, I am not a specialist I am just using my judgement here.

You want a hyaluronic acid serum that is low-molecular weight so that it penetrates rather than sitting on top of the skin. Personally I love the HA Serum from Jaba Labs. It's a large 16 oz container that is $89.00. It has a fairly thick consistency, so I apply it right after the shower all over when my skin is damp.

Right now my face is peeling from my cheeks to my chin--no redness or burning. I should have stuck with mixing the two serums together instead of layering them. The Devita C does seem to have good buffering agents, but my skin is quite sensitive. When the peeling stops, I'll try using the C every other day, mixed with the HA serum. If I don't see any noticeable results using C, I won't repurchase it. I do love HA serum--it's made a big difference in my skin's hydration.

Mayjak, I am not sure what results you are looking for but I wouldnt say that "C" Serums really show a noticable result, more like a preventative measure for skin along with SPF, like taking an antioxidant internally to "keep yourself healthy" or like taking Vitamin C to prevent a cold, such as that.

I will say that I do get a clarity/brightness to my skin using Devita C, and I have tried others and this one definately does brighten the skin.

As far as wrinkles, who knows maybe it is helping, I dont have hardly any (and I use Botox for the deep "1" in between brows, but I feel like Retin A is my work horse there. And I only had fine lines around the eyes and RA (probably in conjunction with C and SPF has really dissapated those)

It does take time to see noticeable results or to realize you have no new wrinkles or fine lines, which I can speak too, in the 4+ years of using Vit C, SPF and Retin A, I can say that I have no new wrinkles, and my skin definately looks younger than 4 years ago.

So to conclude, Vitamin C and SPF to prevent and protect and a nite treatment to repair and prevent.

:)

Southern Fried Chick...hi! Yes, the ha serum is by NeoCell as well. Sometimes I use both serums and somethings just one. But the NeoCell Collagen + C liposome serum sinks in super fast..no problem applying anything over it. I have noticed my skin brighten and become even in tone (no brown spots)

Thank you, ladies, for your helpful responses. I take each tidbit of information and use them to figure out what is best for my skin. I will give the Devita C a good run!
