Face wash, creams, a serum, magnesium flakes and collagen powder with added vitamin C, in sizes from a 20 g cream to 5 kg of flakes. Skin-care items state their content in grams or millilitres and list their ingredients under INCI names, while powders carry a nutrition table with a serving size. Compare products of the same kind: a cream sold by weight and a serum sold by volume cannot be set side by side, and a powder is compared by the price per serving. Check the product page for each item’s intended use.
Frequently asked questions
How do the labels of skin-care products and powders differ?
A collagen powder is a food supplement, so its label shows a nutrition table, the serving size and the daily serving, with vitamins given as a percentage of the nutrient reference value (NRV). A cream, face wash or serum is a cosmetic, so its label gives the content, the ingredients under INCI names, a batch number and the durability information.
How do I compare a cream, a serum and a powder by size?
Compare like with like. Creams and flakes are sold by weight in grams, serums and face washes by volume in millilitres, so divide the price by the grams or millilitres to compare within one unit. A price per gram and a price per millilitre cannot be set side by side, and a powder is compared by the price per serving instead.
How is vitamin C shown on a powder and on a serum?
On a powder, vitamin C is a nutrient: the nutrition table gives the amount per serving in mg and as a percentage of the NRV, where 100 % NRV is 80 mg. On a serum it is an ingredient named in the INCI list, and the label gives no NRV percentage, so the two labels cannot be compared directly.
