Skeptical [SEP] Ok sooo I don’t know about this one. Clear vitamin C means it is 100% potent, but having an ingredient list that potency is no longer 100%. So upon seeing clear thick serum I was skeptical. Soon as I opened the bottle I added several drops to a small old bottle I own and left it open exposing to air, lights and anything else that causes oxidizing to the vitamin c. It stayed clear. After one week straight no changes. I even popped into the microwave for 8 seconds still clear. Had it contained ferulic acid I would have been less skeptic because FA is a Vitamin C stabilizer. On its own Vitamin C (L-absorbic acid) is unstable and begins to oxidize once the seal is broken. Yes even pure vitamin C in water it will turn a slight yellow and begin to darken.<br /><br />But my skin did not break out a good thing. Even if it doesn’t contain vitamin c the other ingredients are a plus especially glycerin as the second ingredient ... which is a natural humectant, anti microbial and antiviral all meaning moisturized skin that won’t get clogged and controls acne. I do get acne (thank the skin gurus) but I do chemical exfoliate with acids and use a retinol. Two things that cause dry skin. If I should break out from a product then it is pure trash and the PH is way off.<br /><br />So it has it pluses and minuses.
