How
Press the serum lightly into the skin, and let it absorb before day cream and sunscreen.
Sensitive skin?
Start with every other morning, or mix a drop into your cream for the first weeks.
Always use sunscreen during the day. The serum may darken a little over time. That is normal.
Why Linda made it
«Your skin meets pollution, sun and stress every day, and after 50 it shows faster. That is why I made C+ Serum Forte 25 %: several forms of vitamin C, ferulic acid and moisture in one serum. Use it in the morning, always with sunscreen, and give your skin glow and a more even tone.»Linda Johansen, founder · 20+ years of product development
Questions and answers
When should I use the serum?
In the morning on clean skin, before day cream and sunscreen.
Can I use it with acids or retinol?
Yes, but at different times of day. Use vitamin C in the morning and acids or retinol in the evening.
Can sensitive skin tolerate 25 % vitamin C?
It may tingle a little the first few times. Start with every other morning, or mix a drop into your day cream.
Why does the serum get darker?
Vitamin C reacts with air over time, and the colour may darken a little. Keep the bottle tightly closed and away from light.
What if it doesn’t suit me?
