What are skin serums?
Applicable both day and night, the face serums or body serums are topical solutions formulated with oil or water-based light and fluid textures containing high concentrations of active ingredients, higher than other skincare products, and fewer excipients (thickeners, emulsifiers, etc.). Some may contain a primary ingredient, while others correspond to combinations of actives. Usually presented in small glass bottles (15 to 30 mL) equipped with a dropper for easy dosage, they are designed to be easily absorbed when spread on the skin, thus providing a means to quickly and effectively deliver beneficial ingredients through the stratum corneum into the deeper layers for most actives.
It is essential to follow the application of a serum with a moisturizing cream. While the serum targets specific skin issues, the moisturizing cream seals in the previously applied serums to maximize their benefits, as well as hydration.
Why use a skin serum?
Applied before the moisturizer and after cleansing the skin, skin serums help to enhance a skincare routine by delivering large amounts of active molecules. They have been developed to manage and "reverse" a number of different skin issues, including blemishes, dull complexion, enlarged pores, redness, wrinkles, pigmentation spots or dryness, thus addressing various individual needs with just a few drops a day.
The high concentration of active ingredients can, in theory, yield more visible results than other types of skin products.
The potential benefits of serums and the desired results depend on the active ingredients present in the formula. They can thus be hydrating, soothing, mattifying, brightening, anti-inflammatory, etc. However, ingredients that are highly concentrated in a formula can irritate some skin types. It is therefore strongly recommended to always test the product on a small area of the body before applying it more broadly.
Each facial and body serum targets a specific skin issue, depending on the active ingredients chosen.
