What is the percentage of vitamin c, ferulic acid and other active ingredients?

For whatever, reason, Cos de Baha doesn't always list exact percentages of ingredients. As a long-time user of this brand, I can say they have extremely effective products at very low prices compared to other luxury brands with less effective formulas. That said, I suspect this particular serum has around 15-20% SAP, which is the version of vitamin C included in this formula. Here is the full list of ingredients, with the C derivative listed in the first 3 ingredients. Ingredients INGREDIENTS:*Aloe Barbadensis Leaf Extract, Propanediol, Sodium Ascorbyl Phosphate (Vitamin C), Glycereth-26, Dimethyl Sulfone, 1,2-Hexanediol, Betaine, Hydrogenated Lecithin, Tocopheryl Acetate, Ferulic Acid, Allantoin, Sodium Hyaluronate, Dipotassium Glycyrrhizinate, Hydroxyethylcellulose, Xanthan Gum, Citric Acid,*Camellia Sinensis Leaf Extract, *Sambucus Nigra Flower Extract,*Momordica Charantia Fruit Extract *Leontopodium Alpinum Extract *Mark: N.O.I.P 77%

Non irritating vitamin C serum

Lovely light formulation that is easily absorbed. No fragrance and not irritating to skin, which is great. I like the ingredients, although less familiar with the particular vitamin C form that this product use. I use it with other brightening serums that I have had for a while and it seems to work well together to fade my hyperpigmented sun spots gradually.
