My Doctor's Diagnosis: Analysis and Target

The serum The Ordinary Hyaluronic Acid 21% + B5 (with Ceramides) is primarily intended for skin that lacks moisture, is prone to dehydration, tightness, or loss of radiance. The Ordinary brand offers a minimalist, highly concentrated formula that is ideal for strengthening the skin barrier and improving skin suppleness. My expert opinion: this product effectively targets skin dryness, while being suitable for all skin types, including the most sensitive or combination skin, thanks to its fragrance- and alcohol-free formula.

Formula Analysis: Key Assets

Three key active ingredients form the basis of this serum:

• Hyaluronic acid (in various forms) It acts like a molecular sponge, retaining up to 1,000 times its weight in water. The combination of different molecular weights allows for multi-layer hydration, both on the surface and deep down.
• Panthenol (Pro-vitamin B5) : This active ingredient promotes skin repair, soothes irritation, and strengthens the skin's barrier function, thereby limiting insensible water loss.
• Ceramides (sphingolipids and phospholipids) They restore cellular cohesion and protect the skin from external aggressions, helping to rebuild the lipid barrier.

The synergy of these active ingredients guarantees optimal hydration, plumper skin, and improved resistance to environmental aggressors.

Tips and Application Ritual

I apply this serum in the morning and/or evening, on clean, slightly damp skin, before my moisturizer. It is compatible with most active ingredients (niacinamide, peptides, antioxidants). However, I avoid layering it immediately with very acidic or powerful retinoid-based skincare products to preserve skin tolerance.

My Final Verdict & Safety Opinion

This serum stands out for its light, non-sticky texture and excellent tolerance. Its fragrance-free formula limits the risk of irritation. The only possible downside is a temporary film-like sensation if the skin is very dry or if too much product is applied. In conclusion, it is an essential ally for restoring and maintaining skin hydration, with an excellent efficacy/safety ratio.
