Over the last 8 months I have tried 4 vitamin C Serums, sounds like only few products for such a long time, but in order to really have an opinion, long term use is important. I tried The Ordinary Vitamin C Suspension 23% + HA Spheres 2%, Drunk Elephant C-Firma Day Serum, Mad Hippie Vitamin C Serum and Peter Thomas Roth Camu Camu Power Cx30. All 4 of the products are great products, but here are 5 reasons why if I had to choose to have only one, The Ordinary wins by a mile.
- It is the only one of the products that openly declares the concentration of it’s effective ingredients
- It has the highest concentration of Vitamin C delivered to the skin in the most effective form which is L-Ascorbic Acid
- The product is a waterless suspension meaning that it has a very long shelf life
- The price is incredibly affordable at 5,8 Euros for 30ml, it is the lowest price of all four
- A little goes a very long way, you need only the slightest smear to effectively deliver vitamin c to a large area of your skin
I have also seen the brightening and evening effect a Vitamin C Serum has, most evidently with this product.
Some people have experienced sensitivity to the product, that is because it is so concentrated. Usually skin responds sensitively the first few time of use with a stinging sensation but following that it doesn’t happen again. Others have also experienced it pilling up or balling under other products or taking a long time to absorb. That happens when you use too much, you really only need a tiny bit and it takes about 20 seconds to absorb making it the most efficient and effective Vitamin C delivery I have experienced so far.
