Eva, thank you. Yes, the link you provided was very informative. However, now I'm worried that I did more harm than good to my skin or at best provided nothing at all. My main objective is minimizing wrinkles. I'm really noticing the wrinkles and sagging on my face. Overall skin texture and pigmentation is great (the ascorbic acid did help even out skintone). I do have a few broken capillaries on my cheeks and the undereye circles I've had all my life. So my complexion is good, it's just those dang wrinkles. I turn 60 next year and I guess unless I choose the knife or fillers, which I won't, it will be even more wrinkles to come. I have been reading your posts and have started the Clinique w/EUK-134. Think I'll order some VitC+E serum. Do you think the Skinceuticals is a good one also. Which route/preparation would you select if you were my age? I don't want to waste anymore time experimenting. Yes, I'm also going to order La Roche Posay Antihelios or Nivea Light Sensation. I have 4 tubes of Neutrogena so I was waiting to deplete that supply.

Hi Barbara!
1.I would like to suggest one tiny detail to making your own VitC serum at home.
Ususally using Ascorbic Acid wont penetrate into your skin very well and it is extremely unstable (only stable as long as it is in powder form).
Using Magnesium (sodium) ascorbyl phosphate will make your mixture more stable, penetrates better and you can store your mixture in the fridge for 3 weeks without loosing any significant effect.
What is very difficult in making VitC+E serum stable is that while VitC is a water-sollouble vitamin, VitE is a fat-solluble one. You'll have to have a water and a fatty W/O phase and be able to mix it homogenously. Which is impossible without using an emulsifier. And then you'll have to know which one to use so the different Ph values of your mixtures will still bind together and so forth...
Basically it is virtually "impossible" to make it at home in my opinion unless you know enough about cosmetic/bio chemistry or you are a pharmacist.
I have found a link to a website about the stability of VitC, maybe you'd be interested:

Your Neutrogena Ultra Sheer Dry-Touch Sunblock SPF 55 w/helloplex is one of the best sunscreens curently available in the US but La Roche Posay (or any L'Oreal owned brand sold in the EU) have much higher UVA protection in the UVA1 zone (360-400nm, they can protect up to 383nm, while Helioplex protects upto 376nm).
