YouTube short by Shereene Idriss giving concise vitamin C serum recommendations. She endorses SkinCeuticals CE Ferulic and Silmarin CF (notes Silmarin CF contains salicylic acid and suits acne-prone skin), criticizes dropper packaging for causing waste/oxidation, and praises tetrahexyldecyl ascorbate as an oil-soluble, stable vitamin C suitable for sensitive or slightly oily skin. She states she included tetrahexyldecyl ascorbate in her Pillow Talk Derm Major Fade Active Seal Moisturizer and advises using it every morning before sunscreen and as the final step at night.

You want to go for the most tried and true and you do want to go and set yourself back 180 bucks. SkinCeuticals has their CE Ferulic and their Silmarin CF. If you have acne I would go for this guy because she has salicylic acid. I hate that they come in droppers and you end up wasting your money pretty fast if you do not use it as fast as it should be used for the inactive form of vitamin C. I love Tetrahexyl Desolate scorbate because it is best for people with sensitive skin. The reason I love it is because it is oil soluble so if you are slightly oily it works great and it can be used with with any ingredients. It is not going to get oxidized and broken down. I love it so much that I put it into the Pillow Talk Derm Major Fade Active Seal Moisturizer so that I have my two in one every single morning before my sunscreen and at night as the last step of my skincare routine to seal in the goodness of all the other actives that I am using.
