In 2024, three ingredients dominated the skincare field: salicylic acid, retinol and hyaluronic acid. Each offers specific and complementary benefits for the epidermis.

1. Salicylic Acid: The Ally Against Blemishes

Salicylic acid, a beta-hydroxy acid (BHA), is renowned for its effectiveness in the treatment of acne. Thanks to its lipid-solubility, it penetrates deep into pores to eliminate dead cells and excess sebum, reducing blackheads and pimples. What's more, its exfoliating action promotes cell renewal, improving skin texture and diminishing pigmentation spots. However, excessive use can lead to irritation, especially for sensitive skin. We therefore recommend starting with low concentrations and gradually increasing according to skin tolerance.

2. Retinol: The Anti-Aging Champion

Retinol, derived from vitamin A, is widely recognized for its anti-aging properties. It stimulates collagen production and accelerates cell renewal, reducing the appearance of fine lines and wrinkles. It also improves skin texture and reduces pigmentation spots. However, retinol can cause irritation, including redness and peeling, especially when used for the first time. It is therefore advisable to introduce retinol gradually into your skincare routine, starting with an application twice a week, then increasing the frequency according to skin tolerance. In addition, retinol makes the skin more sensitive to the sun, so daily sun protection is essential when using it.

3. Hyaluronic acid: the overrated moisturizer

Hyaluronic acid is a molecule naturally present in our dermis. This property makes it a powerful moisturizer, helping to keep skin supple and plump. Hyaluronic acid is generally well tolerated by all skin types, but some people cannot tolerate hydrolyzed hyaluronic acid.

Combining these active ingredients : Precautions and synergies

Combining these three active ingredients can deliver significant results, but requires a careful approach to avoid irritation. For example, the combined use of retinol and salicylic acid should be approached with caution, as both possess exfoliating properties which, together, can increase the risk of irritation. It is often recommended to use salicylic acid in the morning and retinol in the evening, taking care to moisturize the skin with hyaluronic acid to soothe and maintain hydration. Sun protection is also essential when using these active ingredients, particularly retinol, to protect the skin from UV damage.
