MORE ABOUT THE PRODUCT
Why you need this serum:
Vitamin C is the holy grail of antioxidants. But not all vitamin Cs are created the same.
Why this serum is different:
Unlike ascorbic acid and other typical water soluble forms of Vitamin C, which are notorious for being unstable, oxidising and irritant, our VITAMIN C SERUM-IN-OIL is formulated with a rare, lipid form of Vitamin C that is rapidly absorbed to deliver potent antioxidant protection directly at the cellular level, without the common downsides of traditional Vitamin C products.
- Powerful Antioxidant: Features a rare antioxidant system of vitamin C, E and punicic acid for a prolonged antioxidant activity, reducing inflammation, and significantly quenching free radicals produced by sun damage and pollution.
- Brightens and Evens Skin Tone: By regulating melanogenesis, this powerful serum adds radiance to the skin and evens skin tone, attenuates dark spots and softens the skin.
- Optimal Moisturisation: Thanks to its oil formula, it effectively repairs, nourishes and minimises transepidermal water loss.
- Acts as a SPF booster : The rare vitamin C in this serum is non-photosensitive, and will boost the protective effect of sunscreen product.
- Premature Skin Ageing Benefits: Regular use helps fend off premature ageing, promoting a healthier, more resilient complexion.
- Helps with occasional spots: Use a drop of this serum and gently massage around the surfacing spot day and night. It will greatly cut the duration of the spot.

PACKAGING
WHY AN OIL-SOLUBLE VITAMIN C?
Classic vitamin C (ascorbic acid) is water-soluble and highly acidic. This serum uses ascorbyl tetraisopalmitate, an oil-soluble, non-acidic vitamin C that is stable, non-photosensitive and well absorbed by the skin, so it can be used every morning.
EFFECTIVE PROTECTION FROM THE MORNING ON.
Compared with conventional forms, it is non-photosensitive and resistant to oxidation, helping it remain effective in the morning, when the skin needs it most.
MORE EFFECTIVE, LESS IRRITATING.
Unlike conventional, highly acidic forms, its lipid-soluble form is easily absorbed and particularly well tolerated, even by sensitive skin.
A TRIPLE ANTIOXIDANT.
Vitamin C, vitamin E and punicic acid work together for long-lasting antioxidant protection.

VITAMIN C SERUM-IN-OIL FAQ
Can I use this vitamin C serum in the morning?
Yes, this serum contains a biotech ingredient that is a rare oil form of the vitamin C. It is stable and is not photosensitive, so it is perfect for the morning.
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-photosensitive and effective without irritation. For sensitive skin, we recommend not to massage the product into the skin, and instead gently spread and pat the product on.
I have reactive skin, can I use this serum?
We recommend you do a small patch test on the inside of your elbow for a couple of days. Then, we would recommend you mix 1 drop of the serum in your light moisturising cream for a week. Then, increase to 2 drops for another week, then to 3 drops for another week, and then apply directly on your skin. The product improves damaged skin barriers, so once your skin gets used to it, it will also improve your skin reactivity.
Will Vitamin C Serum in Oil work on my deep-set wrinkles?
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, our Vitamin C Serum-in-Oil’s antioxidant and anti-inflammatory elements will help minimise acne and blemishes. If you get occasional breakouts, our Vitamin C Serum-in-Oil will help the blemishes clear up more quickly.
Can teenagers use this product?
Yes, teens can use this product. They can use it as a single product moisturiser, to target minor blemishes, and to help protect from the sun (as an antioxidant).
How fast do I have to finish the bottle before it oxidises? Will it stain my pillowcase orange?
Unlike ascorbic acid, this serum will not oxidise. But like all oils and oil forms, use it within a period of 6 months once opened. This serum will not turn orange or yellow to stain your fingers or sheets.
Can I use it morning and night?
Because this is a potent product, we would recommend it once a day, preferably in the morning. However, if you are on a beach holiday or you have had a strong sun exposure during the day, application of this serum again at night will be beneficial.
How do I combine it with the Cellular Hydration Serum?
Gently massage 3-5 drops of the Cellular Hydration Serum into your skin first, then apply 3-5 drops of our Vitamin C Serum-in-Oil.
