My Doctor's Diagnosis: Analysis and Target

The serum Cosrx The Hyaluronic Acid 3 Serum is primarily intended for skin that lacks moisture, is prone to dehydration, tightness, or loss of radiance. This product from the Cosrx brand aims to restore the skin barrier and improve skin suppleness. Its multi-level hydration formula makes it ideal for dry, combination, or sensitive skin, but it can also be used on mature skin with fine lines caused by dehydration. My expert opinion: the formula is designed to strengthen the skin barrier and provide immediate comfort, while remaining light and non-greasy.

Formula Analysis: Key Assets

Three key active ingredients stand out in this serum:

• Hyaluronic acid (Sodium Hyaluronate) : Available in various forms, it acts like a molecular sponge, retaining water in the epidermis and plumping up the skin. It has an immediate effect on skin hydration and suppleness.
• Ceramides (Ceramide NP) : Essential for cell cohesion, they restore the skin barrier, limit water loss, and protect against external aggressions.
• Natural moisturizing factors (NMF: Sodium PCA, Betaine, amino acids) : They mimic the skin's natural components to maintain optimal moisture levels and strengthen skin tolerance.

The synergy of these active ingredients guarantees deep and lasting hydration, while respecting sensitive skin.

Tips and Application Ritual

I apply this serum morning and/or evening to clean skin before moisturizer. It fits perfectly into a minimalist or more elaborate routine. Compatible with most active ingredients (niacinamide, peptides, vitamin C), it is best to avoid immediate combination with powerful exfoliants (AHA/BHA) to limit the risk of irritation, especially on sensitive skin.

My Final Verdict & Safety Opinion

This Cosrx serum stands out for its light texture, rapid absorption, and effective moisturizing properties. Its fragrance-free formula limits the risk of skin intolerance. The only downside is that it contains a small amount of alcohol, which may cause discomfort on very sensitive skin. In conclusion, it is an excellent choice for restoring and maintaining skin hydration while strengthening the protective barrier.
