FAQ

Q: I'm new to vitamin C - is Pure C15™ suitable for beginners?
A: Pure C15™ is specifically formulated for experienced vitamin C users due to its high 15% L-Ascorbic Acid concentration. If you're new to vitamin C, our experts recommend starting with a lower concentration such as Medik8 C-Tetra® (7% vitamin C derivative) and gradually building tolerance before progressing to Pure C15™. This approach allows your skin to adapt whilst minimising the risk of sensitivity.

Q: Why does Pure C15™ come in two separate bottles?
A: The innovative dual-bottle packaging system is designed to maximise stability and potency. L-Ascorbic Acid is notoriously unstable and can oxidise when exposed to air, light and heat, which diminishes its efficacy. By supplying the formula in two smaller 15ml bottles filled with nitrogen during manufacturing, we minimise oxygen exposure and ensure each bottle maintains optimal freshness. Use one bottle at a time, completing it before opening the second for maximum results.

Q: How long will I see results from using Pure C15™?
A: While individual results vary, most users notice an immediate brightening effect and improved skin radiance within the first few applications. For significant improvements in fine lines, skin firmness and hyperpigmentation, consistent daily use for 8-12 weeks is typically required. The rechargeable antioxidant network ensures sustained potency throughout your treatment, supporting progressive visible improvements in skin quality and tone with continued use.

Q: Can I use Pure C15™ if I have sensitive skin?
A: Pure C15™ features an optimised pH formulation designed to minimise irritation, and many individuals with sensitive skin use it successfully. However, the 15% L-Ascorbic Acid concentration is relatively high-strength. We recommend patch testing before first use and introducing the product gradually - perhaps starting with application every other day before building to daily use. If you experience persistent irritation, speak to our skincare experts who can recommend a gentler vitamin C alternative.

Q: Should I refrigerate Pure C15™?
A: Yes, refrigeration is recommended for optimal freshness and extended potency. Whilst the nitrogen-filled packaging and rechargeable antioxidant network provide excellent stability at room temperature, storing Pure C15™ in the refrigerator offers additional protection against heat-induced degradation and provides a refreshing, cooling sensation upon application. Each bottle maintains full efficacy for 8 weeks after opening when stored properly.

Q: Can I use Pure C15™ with my vitamin A (retinol) products?
A: Absolutely - in fact, this combination is highly recommended as part of Medik8's pioneering CSA Philosophy. Use Pure C15™ in the morning (Vitamin C + Sunscreen) for antioxidant protection throughout the day, and apply your vitamin A product at night for cellular renewal and repair. This complementary approach addresses skin ageing from multiple pathways, delivering comprehensive anti-ageing benefits. Our experts can provide personalised layering guidance for your complete routine.
