The serums are real nuggets for the skin and make a real boom on the cosmetics markets. What are they composed of? How to use them? Lighting with Caroline Nègre, director of scientific communication Yves Saint Laurent.
What are the differences between a serum and a treatment cream?
The serums have a greater asset concentration. Their texture is more fluid and it penetrates the skin faster than a day cream.
How to use it? Under the cream, instead or mixed with?
It is better to use it under the treatment cream to hydrate the skin well and prepare it for makeup.
How often to use it?
You can use it in a cure of 3 to 4 weeks, especially when the skin changes, during seasonal changes. But you can also use it throughout the year especially when it responds to specific skin problems (anti-aging, dry skin …)
When is it better to use it?
You can use it morning and evening without problem by avoiding the eye area which is a particularly sensitive area.
Is it better to use the serum with the care cream of the same range or does it not matter?
I recommend using serum and care cream of the same range and the same brand to avoid incompatibility problems between assets that could create a plush effect on the skin.
