What To Look For In The Best Vitamin C Serum

 PH Levels

pH Levels are of the utmost importance when considering the best vitamin c serum to buy. Many people automatically think a stronger concentration of L-Ascorbic means the product is superior (20% vs 15% L-ascorbic acid) but that isn’t necessarily true.  A serum should have Ph levels of 3.5 maximum (preferably lower), otherwise it won’t penetrate the skin which is the objective. Skinceuticals holds the patent for a CE Ferulic serum with a pH level between 2.5 and 3.0 which is the lowest on the market.  Other more affordable brands have pH levels in the 3.0-3.5 range; still low enough to be competitive but not quite as good as Skinceuticals CE Ferulic Acid. If money is no object and you want the best vitamin c serum on the market I would suggest SkinCeuticals C E Ferulic. Other products such as Cosmetic Skin Solutions Vitamin C+E Serum have higher pH levels that are just slightly higher than Skinceutical’s (as not to violate their patent) but still low enough to be very effective.


Does the product offer any additional beneficial ingredients? The best vitamin c serums combine the power of Vitamin C with ingredients like Vitamin E or Hyaluronic acid for a super potent combination. Hyaluronic acid is a super moisturizing base that works to deliver moisture deep into the pores. Other skin boosting ingredients that work well with Vitamin C includes phloretin and ferulic acid. Other formulas may come with skin soothing ingredients like green tea extract and rosehip.

Skin Type

A topical vitamin c serum with high levels of ascorbic acid may be too strong for those with sensitive skin. If your skin is sensitive you may want to start off with a more milder solution such as Ole Henriksen Truth Serum. It may take some time for skin to adjust to a product with strong levels of vit C, especially in the beginning. If your skin is sensitive you may want to start off by applying the serum just every other day or every few days. Gradually work up to where you can apply it once  day.


Some vitamin C serums are packaged in a vial while others may come in a powder form. Liquids in a vial require you to be more careful since they can break if you drop them on a hard surface. Serums are also more prone to oxidation because it will be exposed to oxygen every time you open the bottle. A powder will require you to mix it with your moisturizer but won’t oxidize as rapidly since it’s not technically mixed until you add a moisturizing base.


Pricing can vary greatly; the most touted antioxidant vitamin c serum from Skinceuticals is on the pricey/high-end side while other brands such as Cosmetic Skin Solutions offer more affordable pricing. Then you have brands like Ole Henriksen and Philosophy with prices that are more in the middle. The vitamin c serum you’ll choose will most likely depend on your budget and needs. If you want a product that has been featured in scientific studies and clinical test you may want to pay extra for Skinceuticals. On the other hand, some of the more affordable brands also have excellent reviews on Amazon. The best vitamin C serum for your skin will depend on your needs and budget.

Delivery System

The two most common delivery systems in the best vitamin c serums are L-ascorbic acid and Magnesium Ascorbyl Phosphate (MAP). L-Ascorbic is more potent due to the low PH level and offers superior skin penetrating abilities but irritation may be an issue for those with sensitive skin. Like L-Ascorbic acid, MAP is a derivative that has been studied extensively and proven to be stable with numerous skin care benefits. Another option is THDA (Tetrahexydecyl Ascorbate) which is oil soluble and stable Vitamin C Ester with potent antioxidant capabilities. There are many different vitamin c serum formulas available and everyone’s skin is different; one person’s skin may react well to one product while another may end up with irritation. You may have to experiment in order to find the best vitamin c serum that works for you.
