My Doctor's Diagnosis: Analysis and Target

Byoma Hydrating Serum is primarily intended for skin that lacks moisture and is prone to dryness, dehydration, or sensitivity. The Byoma brand offers a formula that focuses on restoring the skin barrier and providing biomimetic active ingredients. My expert opinion is that this serum effectively targets imbalances in the hydrolipidic barrier, while being suitable for a wide range of skin types, including fragile skin or skin exposed to external aggressions.

Formula Analysis: Key Assets

Three active ingredients stand out in this formula. First, the glycerin, a powerful humectant, attracts and retains water in the epidermis, ensuring immediate and lasting hydration. Secondly, the squalane, a biomimetic lipid, strengthens the skin barrier and limits insensible water loss, while providing softness and suppleness. Thirdly, the ceramide-cholesterol-phytosphingosine complex replicates the natural structure of the skin barrier, promoting repair and protection against external aggressions. The presence of lactic acid, in low concentrations, contributes to gentle exfoliation and improves skin texture. This synergy of active ingredients explains the product's quality and its effectiveness in terms of hydration and skin resilience.

Tips and Application Ritual

I recommend applying Byoma Hydrating Serum morning and evening to clean skin before moisturizer. It fits perfectly into a minimalist routine or as a complement to soothing active ingredients (niacinamide, panthenol). It is compatible with most skincare products, but I do not recommend using it at the same time as powerful exfoliants (high-concentration AHA/BHA) to avoid irritation, given the presence of lactic acid.

My Final Verdict & Safety Opinion

Byoma Hydrating Serum stands out for its biomimetic formula, which respects the skin barrier and is suitable for sensitive skin. Its light texture penetrates quickly without leaving a greasy residue. A slight drawback could be noted for very oily skin types, which may prefer an even more fluid texture. In conclusion, this serum is an excellent choice for safely restoring and maintaining skin hydration.
