I would think they should be applied at different times. Vit C in the AM with sunscreen & Retin-A at night.

Vitamin C is fragile & the 2 together would probably be very irritating.

Thats the general knowledge too.

And it depends upon the forms of each. I use a non-acid form of C along with a microencapsulated form of A twice a day (with sunscreen of course) and my skin tolerates it, but Ive worked up to this regi over a year or so.

I've never heard of them canceling each other out, just the possibility of irritation when using at the exact same time.

Vitamin C and copper peptides are not compatible together. These ingredients must be applied at different times as they will cancel each other.

They won't cancel each other out, but using them together can be extremely irritating and knowing the result you had with Liz Earle, I wouldn't recommend it.

On his forum/blog a while ago Dr Pickart responded to some of his followers who said they have "beautiful skin" while using CPs and Vitamin C at the same time by saying that if it works for them, continue on.

I think the C would be cancelled out if used at the same time as Retin-A or CPs. Only one active would be working whether it be Retin-A or CPs, the C would be gone.

It is fragile & should be applied first (if you really want to use them together) with at least a 30 min wait time before applying Retin-A.

This may not be worth doing though since it will more than likely cause excessive irritation. You can always give it a try.

If you decide to try, definitely use the wait time to get any benefits out of the C.

What utter nonsense – there is nothing to suggest that Vit C can cancel out Vitamin C at all. This is nothing more than scaremongering. The Vit C and CPs were a big debate at one point and Dr Pickart said that they would cancel each other out but he changed his mind when people said they used both and had got good results.

Retin A and Vit C are both great topicals that do different things and they wouldn’t and can’t cancel each other out at all. Likewise the idea that only one active can work at one time is comlete nonsense and incorrect. Besides, I’m not so convinced if you were using both C and Retin A, that C would lose out in fact it may even be the opposite. The real issue is in maintaining the correct ph of the Vit C to ensure its strength and effectiven3ess.

Well its your skin, and if you are okay with dealing with awkward results then do it but knowing you have the reaction you had with Liz Earle then that's your choice but Retin A is a prescription medicine and so you should really be working with someone qualified in its usage.

I've used Retin A for over 30 years, and have worked with a derm for that whole period of time. I would hope you are working with a derm, but I know many people self medicate with it and then have to deal with consequences so if you are okay with them that's fine.

Hi TheresaMary,

Wasn't suggesting that Vit C can cancel out Vit C? Nor that no 2 actives can be used together. Retin-A & CPs work together. Nor trying to scare anyone.

Vit C is on the fragile side, that is why I suggested a 30 min wait time. Retin-A & C together even with a wait time would still be irritating.

Yes, it all comes down to pH with Vit C.

Why do you want to use them together Salome? Or are you just asking out of curiosity?

because i am using a c serum in the morning.. was thinking if i use c serum twice a day would it be better..

current is c in morn.. retin a at night..

free skin care · Mon Jun 02, 2014 8:28 am

so end of the day the best would be

c in the day and a at night?

reasons:
- irritation = a + c
- possibilities of cancelling each other out??

could i say that?

Its not been discontinued and is still available, although the regulations have tightened up and it is now only available with a prescription. [quote="Salome_B"]

No they cannot and will not cancel each other out - its entirely wrong to say so, and its not factually based at all. What may happen is using both together will definitely cause you irritation but also it may change the PH levels of the Vit C making it less somewhat effective as a result.

If you are using C in the day, and A at night that's working well for you then keep doing it. Don't try doing too much or you will simply stress your skin out and make things worse than they need to be.

That does suggest that you think the Vit C can cancel out the Vit A? Also you said “Only one active would be working” that again does suggest that 2 actives can’t be used together or am I missing something?

Depends on the skin type etc. From my perspective the main issue would be the ph levels of the Vit C.

Well that is strange, but it isn't the case for me. I don't know if maybe there is some reason for it in your country but its still available over here but requires a medical prescription, and to be honest I don't think they would ever stop it because a lot of people use it.
