FAQ

Q: Will this serum darken or change colour over time?
A: Yes, L-ascorbic acid naturally darkens when exposed to light and air. This is a normal occurrence with pure vitamin C formulations. However, SkinCeuticals has conducted extensive testing confirming that oxidation is minimal and the formulation remains effective for up to 6 months after opening. The colour change does not indicate loss of efficacy.

Q: What is the difference between Phloretin CF and C E Ferulic?
A: Both are premium vitamin C serums, but they target different concerns and skin types. Phloretin CF is specifically formulated for normal, oily, and combination skin types, with a particular focus on addressing discoloration and hyperpigmentation. C E Ferulic contains 15% vitamin C and vitamin E, making it ideal for dry, normal, and sensitive skin types primarily concerned with fine lines, wrinkles, and loss of firmness. Our experts recommend Phloretin CF for those whose primary concern is uneven skin tone and discoloration.

Q: How long before I see results from using Phloretin CF?
A: Based on clinical studies, initial improvements in skin brightness and radiance may be noticed within 4-6 weeks of consistent daily use. More significant improvements in discoloration, fine lines, and overall skin tone typically become evident after 12 weeks of continued application. The 24-week clinical study demonstrated optimal results, with 24% reduction in fine lines and 19% improvement in discoloration. For best results, use consistently each morning followed by sunscreen.

Q: Can I use this serum with retinol or other active ingredients?
A: Yes, Phloretin CF can be incorporated into a comprehensive skincare regimen with other active ingredients. Our experts recommend applying Phloretin CF in the morning for antioxidant protection, and reserving retinol for evening use. This approach maximises the benefits of both ingredients without overloading the skin. Allow the serum to fully absorb before applying additional products, and introduce gradually if you're new to active ingredients.

Q: Why must I use sunscreen after applying this vitamin C serum?
A: Whilst Phloretin CF provides powerful antioxidant protection against free radical damage, it does not provide UV protection. Antioxidants and sunscreen work synergistically - the antioxidants neutralise free radicals generated by UV exposure, whilst sunscreen physically blocks or absorbs UV rays. When used together, they provide up to 8 times more protection against environmental aging than sunscreen alone. Always follow application with a broad-spectrum SPF 30 or higher.
