Description

Een mild dagelijks serum dat de huid laat stralen, geformuleerd met 13% vitamine C (ascorbinezuur). Het is effectief genoeg om donkere vlekjes, onzuiverheden en hyperpigmentatie zichtbaar te verminderen, maar mild genoeg voor de gevoelige huid die nog niet gewend is aan vitamine C. Natriumhyaluronaat en allantoïne houden de huid daarbij gehydrateerd en kalm. Een uitstekend startpunt voor vitamine C voordat je overstapt op hogere concentraties. Gebruik overdag altijd in combinatie met SPF.

Three questions we hear

Morning or evening?

Morning is ideal, under your sunscreen.

Can I use it with niacinamide?

Yes. If your skin feels sensitive, use them at different times of day.

Does it change colour?

Vitamin C can darken as it oxidises. Keep it cool and closed, and use it within a few months of opening.
