Maybe you are not really quite sure what it is, or maybe you're happy enough with your usual moisturizer and haven't felt the need to change. But even if you have not tried it, cosmetic serum is getting increasingly more popular, and in fact, it is a boon for your skin.

With help from specialists from the Vichy labs, we have put together the key facts on serum. Thus, if you're wondering about it, but did not know what to ask, continue reading...

A serum is a product typified by its rapid absorption and ability to penetrate into the deeper layers of the skin, together with its non-greasy finish and intensive formula with an extremely high concentration of active substances.

Active ingredients

Like many other skin products, serums are intended to focus on different activities -- anti-aging, brightening, acne prevention, etc.. Because of the high concentrations of the active components, it is common for cosmetic serums to comprise only a few active ingredients that provide intensive nourishment for the deeper layers of your skin.


As with other cosmetic products, serums are oil-and water-based, but the feel is oil-free so the serum can penetrate deep into the skin leaving a non-greasy finish that allows the subsequent application of a treatment cream.

Velvet finish

The oil-free finish does not leave your skin feeling tight after use: instead, it should feel velvety smooth due to the serum's intensive and deep-layer action.


Since the active ingredients are so highly concentrated, a serum will produce more visible results in less time than a simple moisturiser or other skin product

Sensitive skins

Sometimes the high concentration of active ingredients can irritate sensitive skin. That's why products such as Vichy's LIFTACTIV Serum 10, have been developed especially for this type of skin.

How to use

Apply serum to wash skin to optimize penetration of the active components. It is possible to use a serum alone or in addition to your standard daily skin products.


Massage can be quite effective in helping the serum penetrate more deeply. The Vichy Institute has developed a lift-effect face massage that will enhance the effects of anti-aging serum.


Serums aren't only acceptable for mature skins. They may be used at any age, choosing whichever is applicable: antioxidant, moisturizing, nourishing, energizing, etc..


As we have noted, the concentration of active ingredients is higher -- up to twice as much -- as in ordinary face lotions, and you can hope for better results in a shorter time, which explains the apparently higher price of serums.
