What is facial serum?

The facial serum is a fluid with high concentration of active ingredients and rapid absorption by the skin. Its main function is to moisturize and care for the face as a whole. Regarding its texture, it is similar to a serum, of watery consistency, less dense than a cream. It is normally sold in small bottles and applied using a dropper.

About three to four drops are enough per application. The lightness of the product ensures that it is deeply absorbed by the skin without leaving it greasy or sticky. Overall, it is a complete product that guarantees a number of benefits for the health of the face.

What are the benefits of facial serum?

The facial treatment proposed by the serum is thorough. Its main advantage is in the composition, which is rich in concentrated and potent actives, ready to act effectively. It is known for its intense hydration, cell renewal, fast absorption, anti-ageing action and bleaching action of unwanted spots. It also helps remove wrinkles, regenerates collagen and elastin fibres, increases skin immunity and guarantees shine and good texture all day long.

It is a product that can be used by people of all ages in the process of treatment and prevention of skin dryness and aging.

How to use the facial serum?

The serum can be used twice a day, always with the face completely clean. In the morning, it is recommended to apply three to four drops before applying sunscreen and make-up. At night, before going to bed, you should apply the same amount of the product. If you use a night cream, it should be applied after the serum.

Remember that the drops should be gently spread all over the face until you feel that they are being absorbed by the pores.

What is the difference between facial serum and facial moisturizer?

You can never have too much skin care, which is why we should say that you don't have to choose between serum and cream. In fact, there is no problem in using both together. The serum is a much more concentrated product than the cream.

Its differential is that it has a series of active ingredients that act with specific purposes when in contact with the skin. Most of them are focused not only on cell renewal, but also on skin whitening, antioxidant action or anti-ageing action. These are products that go beyond the barriers of hydration and work with an even clearer objective.

The cream, on the other hand, is designed to moisturise. Because it is not so concentrated, you may take a little longer to see the results, but that doesn't mean you can't do without it! It's also worth mentioning that, in the case of moisturizers, you should make your choice according to your skin type, since some may leave your face a little oily.

Serums, on the other hand, since they are oil-free, have no restrictions in this respect and can be used by everyone. The ideal is that in your night beauty routine, you apply the serum and then the cream, in order to guarantee a complete result.
