How do you store this product?

Please don't buy this product; I don't think they are from the legit timeless distributor, the last order that I made came with wrong vitamin c, cheap vitamin C. I'm very disappointed, and Amazon won't let me give a review.

Has anyone actually tested the PH level upon receipt of the product and if so what was the result?

I tested it with a strip AND an actual pH tester. The strip gave me a 5 (https://www.amazon.com/gp/product/B00S730YWG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) , at which point I contacted the company and they told me that the strips are unreliable. They also sent me a screen shot of their own pH testing instrument with the 2.9 result. Then I purchased my own pH tester (https://www.amazon.com/gp/product/B01ESYG6KQ/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1). Then pH was 2.7. I have been using the serum for about 8 months now and like it a lot.

how much and how often should one apply this?

2-3 drops is all you need! Using more is not a benefit. This is because a little bit of vitamin C serum goes a long way: There’s a limit to how much vitamin C your skin can absorb in a day, so any extra product that you use will go to waste. Manufacturer says 2-3 drops. Can be applied 2x a day morning and night. Apply to cleaned and damp skin. Some dermatologists recommend applying a vitamin C serum in the morning in order to prevent damage from free radicals that can occur throughout the day. If you do choose to use your serum in the morning, you'll need to follow up with a layer of broad spectrum sunscreen, with an SPF of 30 or higher. if you have sensitive skin, you might want to steer clear of vitamin C serum during daytime hours. In some cases, higher concentrations of vitamin C could make sensitive skin more prone to irritation and sunburn. Using it at night helps the skin repair.

When the liquid becomes oxidized does it become ineffective?

No. It still works, it starts being ineffective when it gets to rusty- brown! Watch "hotandflashy" on YouTube at vit C serums, she explained there.
