How to choose the right serum for your skin

Face serum is one of the most interesting beauty products for beautiful skin. For several years, its use alongside other facial skincare has become more widespread and almost all brands offer it. However, there is something to be lost when faced with a multitude of face serums available on the market. We do not always know what it is for, how it works on the skin, and what makes it different from cream. Another question comes up very often: which face serum to choose? To allow you to know more, Pharma GDD offers you its complete guide and presents the criteria to take into account to adopt the ideal serum according to the needs of your skin.

Why do we need a face serum? 

The serum is an intensive facial treatment that provides a treating action on the skin and completes the moisturizer. If the cream provides comfort above all, hydrates the surface layer of the skin, and installs a barrier against aggression, the face serum will not provide any protection on the surface. Its objective is to treat very specific skin problems such as dehydration, dark spots, blemishes linked to acne, wrinkles, and other signs of skin aging, redness, dull complexion, lack of firmness, etc. The formulas face serums generally contain less water than creams, are more loaded with active ingredients, and penetrate deeper into the skin.

There are very targeted serums that will treat for example the area around the eyes (dark circles, bags, expression lines), lips, or the neck, which is often forgotten. Some laboratories have also developed multipurpose face serums that act more on the overall quality of the skin and do not target any particular problem. These serums will play on hydration, the regeneration of skin cells and the repair of damage caused by external elements such as pollution, sunlight, blue light, and climatic conditions. They provide a preventive action and can be used before switching to an anti-aging serum for example. In short, incorporating a face serum into your beauty routine and using it with your cream will bring you more results than using your cream alone. These two treatments are paired together in order to give you beautiful skin for longer.

How do you choose the right serum?

The choice of a face serum depends first and foremost on the irregularities that one wishes to treat to regain clear and uniform skin. In the case of normal skin, we must take into account the skin problems that we want to prevent (brown spots, wrinkles, sagging, lack of radiance, etc.). The pleasure of use is also an essential criterion when incorporating a facial serum into your beauty routine. Do not hesitate to request samples or test products in pharmacies when possible. This will make it easier for you to find the texture and smell that you like and that will encourage you to be diligent in applying the serum. Know that oily serums are particularly suitable for dry and mature skin. 

Conversely, the lighter aqueous serums will be perfect for dehydrated, normal, combination, and oily skin. Another criterion may be important in choosing a face serum: the composition. Whether it comes from conventional cosmetics, based on natural ingredients or certified organic, make sure that the composition of your serum favors quality active ingredients, with recognized virtues on the issues to be treated.

For Dehydration

Dehydration is a phenomenon that can affect all skin types, even oily skin. Most often transient, it causes fine lines, discomfort, and gives the impression of a blurred complexion. A moisturizing serum helps to fill the skin's needs in-depth and reduce visible signs of dehydration. We recommend more specifically the serums that contain hyaluronic acid. This active ingredient is widely used in aesthetic medicine for its plumping action but it is above all a powerful moisturizer, capable of retaining up to 1,000 times its weight in water, thus limiting dehydration. Using a facial serum based on hyaluronic acid is particularly advantageous if you also want to curb the appearance of wrinkles and sagging skin. The skin will be densified and wrinkles smoothed.

For Dull skin, lack of glow

The dull complexion and lack of radiance are often linked to oxidative stress induced by the development of free radicals in the body. It is a reaction of the skin that can be favored by several factors: environmental pollution, an unbalanced diet, exposure to UV rays… To remedy this, we recommend that you turn to an antioxidant, anti-pollution and oxygenating, formulated to repair damage caused by free radicals. This type of face care will protect the skin throughout the day and help prevent skin aging. You can also choose a face serum containing vitamin C or fruit acids (AHA), active ingredients are known for their resurfacing, smoothing, and illuminating action.

For Skin Sensitivity, irritations, and redness

Sensitive skin that is regularly prone to irritation, redness, tightness and other feelings of discomfort can also use a face serum provided it is soothing. Prefer products composed of ingredients with anti-inflammatory and protective properties, which strengthen the natural defenses of the epidermis and reduce its sensitivity. Plant extracts such as cotton, chamomile, oats, or evening primrose are particularly suitable for sensitive skin.

For Imperfections 

Blemished skin can be treated with a suitable face serum. For this type of skin, choose to purify, sanitizing, and healing serums. They help remove blemishes, regulate sebum production, and also limit residual marks which can then leave brown spots on the skin. Choose aqueous, lighter formulas, and active ingredients such as tea trees, zinc, and salicylic acid. Certain face serums combine an action against imperfections and the signs of skin aging. They thus respond to an increasingly frequent problem, that of skin faced with a form of adult acne.

Age spots

Skin aging is a phenomenon that can be curbed and treated with a face serum. From your thirties, you can use an anti-aging serum based on hyaluronic acid daily to maintain the hydration level of the skin, fill in the first wrinkles, and identify the tissues. This will help you have beautiful skin for longer. Mature skin can turn to serums with more advanced anti-aging active ingredients such as peptides, antioxidants, fruit acids, or retinol for example. The objective is twofold: to stimulate the synthesis of collagen and elastin, two elements that maintain the firmness of the skin, and to protect the epidermis from aggressions which can accelerate its aging and cause damage.


Dark spots are pigmentation defects that can affect all skin types and have different causes: sun, age, acne marks, etc. An anti-stain serum will act directly on melanin (the pigment that causes skin pigmentation) and regulate its production. This will help correct irregularities, even out the complexion, and prevent new spots from appearing. Vitamin C and fruit acids are known to help fade dark spots and restore a uniform and luminous skin texture.

Bottom Line

A face serum is an intensive treatment that will penetrate deeper than a moisturizer or night cream to treat one or more skin issues: dehydration, dull complexion, lack of radiance, sensitivity, redness, imperfections, aging, brown spots, etc. All skin types can adopt a face serum in their beauty routine. To choose it well, three criteria are essential: the problem to be treated, the pleasure of use, and the active ingredients present in the composition. For visible results on the skin, it is advisable to apply your face serum morning and evening. It is also possible to use it only as a cure when the needs of the skin change under the impulse of internal factors (stress, fatigue) or external factors (pollution, climatic conditions). Whatever defect you want to correct, a face serum will be more effective than a cream alone.
