Hyaluronic acid serums provide intense hydration by drawing moisture from the environment into your skin. They instantly plump and smooth fine lines, improve skin texture, and create a healthy, dewy glow. The lightweight formula absorbs quickly without leaving a sticky residue, making it perfect for layering under other skincare products. Learn more about what hyaluronic acid does to the skin
Use hyaluronic acid serum twice daily - morning and evening - after cleansing and before moisturiser. Apply to damp skin for maximum hydration benefits. It's gentle enough for daily use and works well as the first serum step in your routine before heavier treatments.
Yes! Hyaluronic acid is one of the most compatible skincare ingredients. Layer it after vitamin C serum in your morning routine, or after retinol in your evening routine. The hydration helps buffer stronger actives and reduces potential irritation. Always follow with moisturiser and SPF during the day.
Absolutely. Hyaluronic acid is non-comedogenic and won't clog pores. In fact, it can help acne-prone skin by providing essential moisture without the heaviness of rich creams. Well-hydrated skin has a stronger barrier function, which can actually help prevent breakouts.
Apply 2-3 drops to clean, slightly damp skin. Pat gently until absorbed, then follow with moisturiser to seal in the hydration. For best results, use on damp skin - hyaluronic acid needs water molecules to bind to for maximum effectiveness.
Hyaluronic acid serums are concentrated treatments that draw moisture into the skin, while moisturisers create a protective barrier to prevent water loss. Use them together for optimal hydration: serum first to add moisture, then moisturiser to lock it in.
Hyaluronic acid is extremely well-tolerated by most skin types with minimal risk of irritation. In very dry climates, it may initially feel slightly drying if not followed by moisturiser, but this is easily prevented by proper application technique and layering.
