Frequently asked questions
Which Double Defence kit should I choose?
Which Double Defence kit should I choose?
Each kit pairs a SkinCeuticals antioxidant serum with a matched SPF 50, so pick by skin type. Choose the C E Ferulic kit for normal, dry or mature skin; the Phloretin CF kit for ageing and uneven tone on normal-to-oily skin; the Silymarin CF kit for oily and blemish-prone skin. All three deliver the brand's prevent-and-protect step in one box.
How do I use a Double Defence kit through the day?
How do I use a Double Defence kit through the day?
Apply the antioxidant serum first thing on clean, dry skin — four to five drops of C E Ferulic, Phloretin CF or Silymarin CF before anything else — then finish with the paired SPF 50 as your last morning step. The serum defends against free radicals while the sunscreen blocks UV, so the two act as a single daytime shield. Reapply the SPF across the day when you're outdoors.
Why pair an antioxidant serum with sunscreen instead of using SPF alone?
Why pair an antioxidant serum with sunscreen instead of using SPF alone?
Sunscreen filters UV, but antioxidants like vitamin C and ferulic acid neutralise the free radicals that slip past and drive dullness and premature ageing. Using both, as the Double Defence kits do, closes that gap for fuller daytime defence. It's the reason SkinCeuticals designed each serum and SPF to be worn together.
Can I add eye protection to my Double Defence routine?
Can I add eye protection to my Double Defence routine?
Yes — Mineral Eye UV Defense SPF 30 extends the same protect step to the delicate eye contour, where facial sunscreen is easy to miss. Its mineral filters and light tint shield the area and soften the look of dark circles. Pat it on last, after the kit's serum and SPF.
I have oily, breakout-prone skin — which kit won't feel heavy?
I have oily, breakout-prone skin — which kit won't feel heavy?
The Silymarin CF Double Defence kit is the one to reach for: its oil-free vitamin C serum contains salicylic acid to keep skin looking clearer, and the paired SPF wears light on oily skin. You get antioxidant defence and sun protection without a greasy finish. Cleanse well beforehand so both layers sit evenly.
