I usually use Retin A at night. After I got my 20% vit c serum, I've been applying it both moring and night after I cleanse my face. I haven't used retin A on top of vit c since i'm not sure if it can be mixed together. Do you know if it's ok to mix the two together?

Yes, you can apply underneath retin A. Apply after cleanser and toner.

Natalyn,
Have you tried Vit C in the morning?

Which is more beneficial: a.m. or p.m. application? Thanks!

Yes, this is how to do it. The C and A are a great combo for building collagen, which is why I use my C at night and have for many months now.

PBI....It is know thought that LAA serums should be applied at night because they quickly oxidize when exposed to light.

Technically, you can mix them, but I personally would not do it. These are two very potent actives, so it's better to let them work by themselves, in my opinion.

riley, which Vit C serum do use now? Have you tried DIY Vit C? I made one a few days ago ( followed one of Kassy's simplest recipes EXACTLY) and burnt my skin Confused

I use Skinceuticals C, E, Ferulic. This is what works for me, so I have chosen to stick with it (shock, I know!!). I am not into DIY, so I have not tried anything like that. (Sorry to hear the C burnt your skin. Maybe you could post on the DIY thread and ask for some help with it?)

I use vit C both morning and night. I did not know about losing its effect in the morning. The instruction states that I should use it both morning and night, so I follow the instruction. Embarassed I apply sunscreen after I let the vit c serum dry on my skin though. It dries quickly since it's like water. I do notice the skin tightening effect so far.

I wouldn't worry about that. Most people apply their C in the morning and follow that with sunscreen.

Thanks for the great info..I'll start doing this at night...do you use C in am as well? Do I have to wait 20 minutes after cleansing to apply vit c then wait again to add vit A?

I will use C in the am only in the summer months if I am going to be outside for a long time, as the C helps your sunscreen with better protection. I do not wait 20 minutes ever! I wash my face, and apply the C, wait about 3 minutes and then apply whatever else I am going to apply on top of it. HTH! Very Happy

if we use vitamin C in the day time, would we be increasing our risk to sunburnt?

our skin gets sunburn or sensitive when apply vitamin C and expose ourselves to sun?

Not with C, as C increases sun protection. A derm once told me that if you got exposed to the sun, without sunscreen, the thing to apply as soon as possible was Vit C, as it would stop the damage doing its worst, and fight the free radicals.

Its Vit A that increases the risk of being sunburnt, not Vit C - thats the opposite.

I've heard that the reason for waiting 20 minutes after applying vit C serum is to get the exfoliation effects. You can still get the other anti-oxidant benefits of the C without the wait.

Some days I can wait 20 minutes, other days I can't...

thanks I thought I read somewhere that I needed to wait for 20 minutes before applying vit C...and it usually is very difficult for me to do so..Glad to hear I wasen't going crazy and that I don't have to wait any longer.

Thank-you, I think you mentioned that you live in South Florida as well. I do spend alot of time outdoors (I run outside and have young children) I am using the Neutrogena ss you recommended. Do you think I should use the Vit C at night (with vit A) as well as during the day (with ss) or only one or the other..It seems to have great benefits for both...hmmmm...

Thanks for all your GREAT advice

You are most welcome! I am in Orlando, Lou. I think if I were you I would do both, as long as it doesn't irritate your skin. But another option for you, you could always use the C in the morning during our horribly hot summer months, and when it turns a little cooler and the sun is less strong switch the C to night before your A.

Hi all, I love how the vit c makes my skin feel tight. For long time users of vit c serum, has any of you seen any benefit like evening out the skin tone or reducing the age spots from using the vit c for a long time?

Skinceuticals C, E, Ferulic did this for my skin after using it faithfully for 3+ months. However, I personally do not think it is the C in that formula that caused the fading of age spots. I think it was either a combination of E and Ferulic acid, or 1 of those ingredients by themselves. (I think this because I have used many C products and none of them have every made a difference on my skin, other than the SC, so this is my own theory for my own skin.)

As I understand it, you should use a cleanser with a ph in the 5.5 range to get the most out of your C serum - If you want to use it straight away after cleansing, without a wait.
If your cleanser has a higher ph, the C (which is a low ph) will not work as well if put on directly after cleansing. The wait time after cleansing is intended for more alkaline type cleansing formulas (ie: those with a higher pH value)...

I've made a very simple Vit C serum and it has burned my skin. Embarassed This is the recipe I was following:


1 tsp LAA
3 tsp distilled water
1 tsp aloe vera gel
1/4 tsp Jojoba oil

step1: LAA + slightly warm water = mix until the crystals are dissolved

step2: Aloe + jojoba = mix
step3: mix the two mixes

I then put the mixture in the fridge.


What possibly went wrong .. What caused the burn?


The 'burn' is because you didn't use enough liquid, to accomodate the 1 tsp of L-AA.

To have a 15% concentration you must put 1 tsp of L-AA into just about 6 tsp of liquid (1oz).

Math is my weakness, but your formula looks to be in the neighborhood of a 25(ish) % concentration Crying or Very sad (4 1/4 tsp of fluid, based on what you wrote)


Just for the record, that's not even close to the recipe I posted though Sad
