Vitamin C serum

I am needing to purchase some fresh Vitamin C serum and am debating on reordering from PSF or trying one of DY's serums.
Have any of you used both? How do they compare?

Refridgerating for long-term storage and keeping the current one out of sunlight and in a cool/dark place really helps delay oxydation.
They last longer and I just love the cool sensation on my face. Drawback, I have to take them to the bathroom with me back and forth.
My vitamin C is a white translucid serum.
I also keep/kept both Vit C in their box away from sunlight in a cool/dark place. The DY still oxidized a lot faster than the PSF. On a whole, I seem to prefer PSF products and customer service to DY.
Same here. The only time the Vit C saw light was when the bottle was out for my morning use. Right now I'm sampling GoW's vitamin C serum and really like the white, opaque, mini treatment pump bottle it came in. Plus, after researching the ingreds, it sounds very good for the skin!

Another question I meant to ask: can the Vitamin C be used if it has turned just slightly yellow? will it still work?
I have a bottle of PSF Vit C that has SLIGHTLY changed color and the date on the bottom says use by 05/08. Should I keep on using it?
I've had this bottle for a good 3 months and have always stored it in the original box, keeping it away from sunlight.

Yes, keep using it. Do you still get a tingling sensation after applying it?
From PSF:
To use: Apply to freshly cleansed & toned skin once daily. Follow with moisturizer, if desired. Keep bottle tightly capped. Store in a dark, cool place. Note: This product bears a "Sell By" date on the bottom of the box. This is the suggested date that you should open this product and begin to use it. From that point on there is a 3-month shelf-life on this product for potency. This is not an expiration date. Product which is passed this date can still be used, however the potency may slightly diminish over time.

BHA first, wait 30, then Vit C, wait 10. You can apply the Vit C earlier, as it's pH is not that much higher than the BHA. Doing so diminishes the effectiveness of the BHA slightly, but not that much. If you want to apply Vit C earlier, you should at least allow 10 minutes after the BHA, just so it sinks in and dries.
You can keep Vit C in the fridge, and it might last a wee bit longer that way before it oxidizes. I don't bother because I usually use up a bottle of Vit C within a month or so, and my fridge is terribly inconvenient to my dressing area.
I don't know.
