What is the role of a serum?

Serums have become an essential part of many people's beauty routine, but what do they really do? This article explores the different functions of serums, their key ingredients, and how they can transform your skin's health. Whether you have dry skin, oily skin combination or sensitive, serums can meet specific needs and bring considerable benefits to your skin.

What is a serum?

A serum is a facial care product based on concentrated active ingredients, formulated to penetrate deep into the skin and moisturize. Unlike a moisturizing cream, which creates a barrier on the skin 's surface to retain moisture, a serum is light and its fluid texture enables it to be absorbed quickly. This type of cosmetic is often presented in glass bottles, sometimes equipped with a dropper for easy application.

The benefits of serum

Serums that combinehyaluronic acid, retinol and p-refinyl are particularly effective in transforming your skin's appearance. Each of these ingredients plays a key role in skin care:

• Hyaluronic acid: As mentioned, this ingredient is excellent for intensely moisturizing the skin. It helps maintain moisture levels, which is crucial for keeping skin supple and elastic.

• Retinol: This vitamin A derivative is renowned for its anti-aging properties. It stimulates collagen production, improves skin texture and reduces the appearance of fine lines and wrinkles. By promoting cell renewal, retinol helps reduce imperfections and even out skin tone.

• P-refinyl: This active ingredient, derived from retinol, combines the benefits of retinol with improved skin tolerance. It is particularly effective in reducing the signs of aging while minimizing the irritation often associated with retinol. p-refinyl also helps smooth skin, reduce redness and improve skin tone.

A serum for every skin type

The serums are formulated to meet the specific needs of each skin type:

• Dry skin: Serums based onplant oils such asargan or shea are ideal for nourishing and protecting the skin barrier.
• Oily skin: Light-textured serums, often in gel form, help regulate sebum production and reduce imperfections.
• Sensitive skin: Soothing serums containing ingredients such asaloe vera orthermal spring water can calm redness and irritation.
• Mature skin: Anti-aging serums, enriched with antioxidants, vitamin C and collagen, aim to firm skin, improve elasticity and reduce the signs of skin aging.

The key ingredients of a serum

Serums often contain powerful active ingredients that can target various skin problems:

• Hyaluronic acid: For intense hydration.
• Retinol: For an anti-wrinkle effect and cell regeneration.
• Vitamin C: For radiance and protection against oxidative stress.
• Niacinamide: Reduces imperfections and evens skin tone.
• Antioxidants: To protect the skin from external aggression.

Complement to your skincare routine

A serum can easily be integrated into your beauty routine. We recommend applying it after cleansing with a gentle cleanser and before a day or night cream. For optimum effectiveness:

1. Cleanse your skin with a cleansing gel or cleansing milk.
2. Apply the serum to the face using gentle movements, concentrating on areas requiring more attention (eye contour, fine lines, etc.).
3. Moisturize with a moisturizing cream suited to your skin type to seal in moisture.

Benefits of serums for the skin

Regular use of a serum can offer many benefits to your skin:

• Complexion radiance: A well-formulated serum can restore freshness to dull, tired skin.
• Texture improvement: Thanks to exfoliating active ingredients, a serum can help smooth skin texture and reduce the appearance of pores.
• Spot removal: Serums containing brightening active ingredients can help reduce dark spots and even out skin tone.

Mistakes to avoid

To maximize the effects of your serum, it is essential to avoid certain common mistakes:

• Skip moisturizing: Don't neglect to apply a moisturizing cream after the serum.
• Overuse: A small amount of serum is enough. Too much can make your skin sticky and clog pores.
• Inappropriate mixing: Certain combinations of ingredients can be irritating. For example, avoid mixing retinol-based serums with those containing vitamin C without professional advice.
