Serums are true gems for the skin and are currently making a significant impact in the cosmetic market. What are they made of? How should they be used? Insights provided by Caroline Nègre, the Scientific Communication Director at Yves Saint Laurent.
What are the differences between a serum and a moisturizing cream?
Serums have a higher concentration of active ingredients. Their texture is lighter and they absorb into the skin more quickly than a day cream.
How should it be used? Under the cream, instead of it, or mixed together?
It’s best to apply it under the moisturizing cream to properly hydrate the skin and prepare it for makeup.
How often should it be used?
You can use it in a treatment cycle of 3 to 4 weeks, especially during times when your skin is adjusting, such as with seasonal changes. However, it can also be used throughout the year, particularly when it targets specific skin issues (such as anti-aging, dry skin, etc.).
What time of day is it best to use?
Serums can be used both morning and night without any issues, but avoid the eye area, which is particularly sensitive.
Is it better to use the serum with the care cream from the same product line, or does it not matter?
I recommend using the serum and the care cream from the same product line and brand to prevent compatibility issues between the active ingredients which could cause flaking on the skin.
