## Questions & Answers

**Q: What is the percent of vitamin C?**
A: Hi, our formula contains 15% pure vitamin C (L-ascorbic acid), 1% vitamin E (tocopherol), and 0.5% ferulic acid and a 3.2 pH which is the most effective combination. It is very important to use the correct form of vitamin C and have the proper pH, you can have higher concentrations of these actives in other forms and they will not be effective. There is some very useful information on the SkinCeuticals site about C E and Ferulic and they have of course helped develop this formula.

**Q: If my moisturizer has hydraulic acid, can I still use it after applying this serum?**
A: Yes, you can use your moisturizer with Hyaluronic acid on top of this serum. (This answer is from an licensed esthetician/skin care specialist)

**Q: Just received and followed directions.  It’s so        sticky on my face!!!! I hate that.  Has anyone else had this issue?**
A: I understand.  I only apply it to my "sun spots" - but it DOES feel a little sticky!  However, the sunspots on my face and hands have almost disappeared … so I am willing to make the trade-off.

**Q: Is this product vegan and cruelty free?**
A: Yes, this product is vegan and cruelty free.
