What Are Serums & Treatments?

Serums are lightweight, fast-absorbing formulas with small molecules that penetrate deeper into the skin than moisturisers, delivering active ingredients directly where they're needed. They are the highest-impact step in any skincare routine — targeting specific concerns like dark spots, fine lines, dullness, and dehydration for results that moisturisers alone cannot achieve. Browse our full Skincare Essentials collection to build a complete routine around your serum. Read our complete guide: Best Serums for Glowing Skin: Your Complete Guide.

Key Ingredients to Look For

• Arbutin & Kojic Acid — gentle, effective brightening for dark spots and uneven tone. Try our Glowing Booster Brightening Essence. Learn more: Arbutin & Kojic Acid: The Brightening Duo for Even, Glowing Skin.
• Retinol — the gold standard anti-aging ingredient for fine lines, firmness, and cell turnover. See the RoC Derm Correxion Firming Serum Stick.
• Hyaluronic Acid — holds up to 1,000x its weight in water for deep, lasting hydration. Read: The Ultimate Guide to Soft, Glowing, Hydrated Skin.
• Vitamin C — antioxidant protection, collagen boost, and immediate luminosity. See our Complete Guide to Face & Body Serums.
• Niacinamide — reduces pores, controls sebum, and strengthens the skin barrier
• Peptides & Collagen — rebuild skin structure and improve firmness over time. See the Derma Clinicals Retinol + Collagen Cream.

How to Apply a Serum Correctly

Apply to slightly damp skin after cleansing and toning, before your moisturiser. Pat gently — never rub. Allow 30–60 seconds to absorb before applying your next product. Use Vitamin C serums in the morning for antioxidant protection; use retinol serums at night only. For an enhanced routine, use your serum immediately after an LED light therapy session — open pores absorb actives up to 3x more effectively.
