Choose HYALU B5 SERUM for hydration and anti-ageing, or Cicaplast B5 Repairing Balm for barrier support. If you want lightweight hydration that smooths the look of fine lines, use HYALU B5 SERUM; for a variant with a different texture and added care for dry areas, consider Hyalu B5 Acid Serum. Consider your climate, whether you prefer a simple routine or layered actives, and always finish with sunscreen in the day.

Hyaluronic acid hydrates by binding water in the skin, delivering plumpness and moisture. Different molecular weights hydrate at different depths: smaller molecules penetrate deeper, while larger ones moisture the surface for immediate smoothing. La Roche-Posay combines hyaluronic acid with Vitamin B5 to support the skin barrier and soothe irritation. Both HYALU B5 SERUM and Hyalu B5 Acid Serum share these core benefits with their own texture preferences.

Beginners will benefit most from HYALU B5 SERUM for straightforward hydration and gentle anti-ageing support. Skincare enthusiasts or those seeking texture refinement may prefer Hyalu B5 Acid Serum 30ml for its variant formula and feel. Both options come from the same Hyalu B5 family and provide Hyaluronic Acid and Vitamin B5, so you can choose based on texture and how your skin responds.

Patch test any new product for 24–48 hours on a small skin area before full use. Apply the serum after cleansing and before moisturizer, then finish with sunscreen in the day. Avoid layering multiple strong actives at once to reduce irritation, and keep routines simple if your skin is sensitive. Store in a cool, dry place and follow La Roche-Posay product directions.

HYALU B5 SERUM is ideal for everyday hydration and visible anti-ageing support. Hyalu B5 Acid Serum, available in a 30ml size, adds an acid-based option that may suit those seeking extra texture refinement or a lighter feel. Both come from the La Roche-Posay Hyalu B5 family and share Hyaluronic Acid and Vitamin B5, so your choice depends on preferred texture and skin sensitivity to actives.
