Skin serums have become an essential part of skincare routines. True concentrates of active ingredients (hyaluronic acid, AHA, etc.), these cosmetic products offer a targeted approach to the specific needs of different skin types and conditions. In this article, we'll explore what a serum is, evaluate its benefits, and see how to incorporate it into your beauty routine.


How does a skin serum work?

A skin serum is a care concentrate rich in active ingredients. Lighter in texture than traditional moisturizers, serums are designed to penetrate deeper into skin tissue. Its very small molecules allow it to penetrate the skin of the face and reach the deeper layers for rapid, very effective and visible action.

Formulated with concentrated active ingredients, each type of serum is designed to meet a specific need. In the list of most common active ingredients, we can find hyaluronic acid, known for its incredible hydrating properties. We can also find in their composition antioxidants, peptides, vitamins, AHA or BHA, among others.

Choosing the Right Serum for Your Skin Type

The serum works as a complement to the moisturizer. Its ultra concentrated composition offers unique benefits that are not always obtained with other care products such as creams or lotions. To choose it, you must first take into account your skin type.

Normal skins : Opt for a lightweight serum designed to maintain your skin's natural balance.

Combination skin : Go for a mattifying serum.

Dry skins : Choose a nourishing and plumping serum to restore the suppleness of the skin.

Oily skin : Opt for a light, non-greasy serum to purify and regulate sebum production without clogging pores.

Once these subtleties are taken into account, the ideal serum must respond to your skin's problems at any given time. Here are some examples of common problems, and their solutions.

Dehydration : Choose a hydrating serum. Hyaluronic acid is the most common molecule. This substance, naturally present in the skin, acts like a “sponge” capable of retaining up to 1,000 times its weight in water. We can also find ingredients such as glycerin, aloe vera, provitamins B5, vegetable oils, shea butter…

Dull skin : Opt for an illuminating serum, for example based on vitamin C. This molecule, highly concentrated in antioxidants, acts on the oxidation of the skin and gives it radiance. You can also rely on AHA, vitamin B3, licorice extract, vitamin E, fruit and enzyme extracts…

Skin aging : Here, you must opt ​​for ingredients that correspond to the condition of your skin: appearance of wrinkles, or established wrinkles, loss of elasticity and firmness, etc. For a antioxidant serum which gives the face a smoother and firmer appearance, you can opt for Le Sérum by Beau Domaine .

Sensitive skin : You should rely on a soothing serum which will calm redness and tightness and restore the balance of the skin barrier. Be careful of perfumes which can attack certain sensitive skin.

Imperfections : Opt for a purifying serum to reduce imperfections, reduce shine and tighten skin texture. You will often find active ingredients such as BHA, AHA, vitamin B3, sulfur, tea tree tea extract, zinc, clay, licorice extract… Beware of products that are too corrosives which could dry out the skin.

There are as many serums as there are skin problems (pigment spots, enlarged pores, etc.) everything lies in one correct diagnosis of your skin condition. If your concerns are multiple, do not hesitate to opt for a versatile serum to avoid having to multiply formulas. The Serum by Beau Domaine for example fights against dehydration and restores radiance to the skin while helping to slow down the visible signs of aging.

Integrate a serum into your beauty routine

Used throughout the year or in courses lasting a few months, the serum is a treatment in addition to your moisturizing cream. It cannot in any way replace your moisturizer, which acts as a protective barrier for your skin. Here's how to integrate your serum into your beauty routine:

Cleanse and tone : Before applying the serum, make sure to cleanse your face thoroughly to remove impurities. Then apply a toner or essence to prepare your skin to absorb the serum's active ingredients.

Application : As a serum is very concentrated, a few drops are enough to cover the face. Place two drops of serum on fingertips and apply to face and neck. Massage the skin gently with upward movements to achieve better absorption. Finish with small taps to stimulate microcirculation and complete the absorption of the product.

Hydrate : Once the serum has been absorbed, seal in the benefits of the serum with a moisturizer suited to your skin type.

Protect : Protect your skin from the sun using a suitable sunscreen.

Frequency : Once or twice a day, preferably in the morning and evening, for optimal results. You can choose to alternate one serum in the morning with another in the evening to better address your skin's specific issues. As with your beauty routine, what matters here is how consistently you apply your serum to ensure visible results.

Much more than a simple beauty product, skin serum is a valuable asset for personalizing your skincare routine. Thanks to its powerful active ingredients and its ability to penetrate deeply, the serum offers a targeted care experience to meet the specific needs of your skin at any given moment. Whether it's fighting the signs of aging, deeply hydrating the skin or adding radiance to your complexion, serum can be the perfect companion for visible and long-lasting results.
