Using multiple serums at the same time can be a great way to boost your skin care routine, but it is important to understand the science behind it before you do.
The reason why people suggest a maximum of two or three serums comes down to layering and penetration. Heaps of brands, salons and experts recommend leaving time between applying your serums and moisturisers, and doing it in a specific order so as to allow all of the ingredients to actually sink into your epidermis.
When you apply multiple serums at the same time, you are essentially layering the products on top of each other. This can prevent the ingredients from penetrating your skin, as the top layer of product will block the ingredients from the bottom layer from being absorbed. This can also cause irritation, as the top layer of product will be sitting on the skin and can cause a reaction.
It is important to note that the order in which you apply your serums is also important. It is recommended to start with the lightest product first, and then layer heavier products on top. This allows the lighter product to penetrate the skin and be absorbed, before adding the heavier products on top.
It is also important to allow time between applying your serums and moisturisers. This is because the serums need time to penetrate the skin and be absorbed, and if you apply a moisturiser too soon, it can prevent the serum from being absorbed.
Overall, using multiple serums at the same time can be beneficial for your skin, but it is important to understand the science behind it. Layering your products in the correct order and allowing time between applying your serums and moisturisers can help ensure that all of the ingredients are absorbed and that your skin is not irritated.
