Essence for the face
Essence is added after the toner.
An essence contains active ingredients, but in lower concentrations than serum or ampoule. Active ingredients such as vitamin C or niacinamide can be used to treat e.g. pigment changes, bring additional moisture to the skin or prevent the first signs of aging.
What is a serum?
The serum is a skin care product that contains active ingredients that are absorbed deep into the skin and effectively treat skin problems.
The serum is added after toner and essence, before the moisturizer. If you use several serums and/or ampoules at once, add them from a more liquid consistency to a thicker one.
Find a serum for aging skin, combination skin, for dry and oily or impure skin .
The difference between ampoule and serum
An ampoule contains active ingredients in high concentrations, which are intended to treat a specific skin problem, such as uneven skin tone or fine lines.
Ampoules often contain only one active ingredient, such as centella, but in higher concentrations than in serum.
Serums, on the other hand, often combine many different active ingredients, so you get the benefits of several ingredients at once.
