What Are Vitamins & Why They Matter
Vitamins are essential micronutrients that play a powerful role in skin health, helping to nourish, protect, and rejuvenate your complexion from the inside out. Vitamin C, for example, supports collagen synthesis and helps brighten dull skin, while Vitamin E works as a potent antioxidant to defend against free radical damage.
Together, vitamins help even out skin tone, reduce signs of ageing, and strengthen your skin’s natural barrier—leaving your skin visibly smoother, healthier, and more resilient.
Dermatologists often recommend vitamin-enriched skincare to boost hydration, calm irritation, and support overall skin regeneration.
How to Choose the Right Vitamin C Serum
Finding the best vitamin serum depends on your skin type, the concentration of active ingredients, and your specific skin concerns:
- Understanding Concentrations
- Low Concentrations (0.5–5%) – Best for beginners or sensitive skin. Offers gentle benefits without irritation.
- Moderate to High Concentrations (10–20%) – Ideal for targeting visible signs of ageing, hyperpigmentation, or loss of firmness.
- Key Ingredients to Look For
- Vitamin C (Ascorbic Acid or Derivatives) – Brightens and boosts collagen.
- Vitamin E (Tocopherol) – Nourishes and protects against environmental stress.
- Niacinamide (Vitamin B3) – Strengthens the skin barrier and improves tone and texture.
- Ferulic Acid – Enhances the stability and performance of Vitamins C & E.
- Pro-Vitamin B5 – Soothes and hydrates.
How to Use a Vitamin Serum for Best Results
Follow these expert-recommended steps to boost absorption and get the most from your vitamin c serum:
- Cleanse Thoroughly: Start with clean, dry skin to allow the serum to penetrate properly.
- Apply on Damp Skin: If using a hydrating vitamin serum (like one with hyaluronic acid or panthenol), apply it on slightly damp skin to enhance absorption.
- Use the Right Order: Apply before moisturiser but after toner (if using). If combining with actives like retinol, alternate days or or separate routines.
- Let It Absorb: Give your serum a minute or two to sink in before moving to the next step.
- Be Consistent: Use once or twice daily, depending on the formula. Morning is ideal for antioxidants like Vitamin C; evening works well for repair-focused blends.

This carefully crafted serum isn’t your typical skincare product; it’s a potent elixir designed to target a range of concerns, from wrinkles and age spots to acne and dryness. Our testers, representing a diverse range of skin types and concerns, all experienced remarkable improvements.
