focus on our star ingredient

The Vitamin C in oil form

Ascorbyl Tetraisopalmitate: a rare form of vitamin C, more stable than water-based vitamin C and extremely well absorbed by the skin (compared to water-based forms which have difficulty negotiating through the skin barrier).
This lipidic form is very effective without irritating.

Certified free of oestrogenic endocrine disruptors

Skin Diligent is the first brand to test its skincare products for endocrine disruption on living cells, to ensure the safety of its finished products.

Most frequent questions

I have sensitive skin. Could this irritate my skin?

No, because the rare oil-form of vitamin C in this Serum is non-acidic and extremely well absorbed by the skin. As a result, it is non-photosensitising and effective without irritation.

Will Vitamin C Serum in Oil work on my deep-set wrinkles?

It won’t make your deep wrinkles disappear, but it will help the skin’s collagen level to plump the skin,
rejuvenating its texture and the appearance of fine wrinkles. Beyond the appearance of the skin, it provides longer term, lasting benefits for skin cell health that will help to combat future skin ageing.

I get occasional acne breakouts. Will Vitamin C Serum in Oil help?

Yes, Serum in Oil’s antioxidant and anti-inflammatory elements will help minimise acne and blemishes. If you get occasional breakouts, Serum in Oil will help the blemishes clear up more quickly.
