  • Description

  • Chemist's Tips
  • Powerful formula that combines 4 types of Vitamin C for total of 17% L-ascorbic Acid when fully converted
    Vitamin C cocktail includes L-ascorbic Acid, Vitamin C Glycerin complex, Magnesium Ascorbyl Phosphate, and Tetrahexyldecyl Ascorbate for optimal stability and efficacy
  • Synergized with the most powerful form of Vitamin E to boost antioxidizing power
    Using Mixed Tocopherols with a variety of Vitamin E isomers, they work in complementary ways to offer broad spectrum antioxidant protection
  • Formulated with Hyaluronic Acid to induce a glowing complexion boasting with suppleness
    Provides below-the-surface hydration to optimize Vitamin C efficacy; promotes more supple and radiant skin via adequate hydration
  • Patented and scientifically proven violet glass to optimize product performance over shelf life
    Protects, prolongs, and revitalizes the bioactivity stored inside ingredients through effective filter of IR, visible light and UV that degrades active ingredients

Use once or twice daily according to professional guidance. Dispense 2-3 drops and massage onto skin in an upward circular motion. Can be used before or after Skin Need water-basedd serum as suggested by your Skin Need Skin Consultant. For oily, combination, and sensitive-prone skin, dilute by blending with 1-2 drops of Skin Need water-basedd serums when use. Patch test before first use.

When using products of high potency, it is advisable to introduce the products into your skincare routine one by one instead of using them simultaneously. That way it is easier to identify the effects when used alone, as well as be able to isolate the product that causes a reaction in case of sensitivity. Patch test before first use as always, and for sensitive prone skin, dilute 1-2 drops with 2-3 drops water-basedd serums during first few times of usage before progressing to full dosage.

For an optimal age prevention and skin brightening routine, introduce Fortified Ferulic Serum, Quadruple Vitamin C Serum, as well as Retinol and Resveratrol Cream one by one into the routine that best cares for your unique skin type + problem combination.

Q&A

Why does the formula incorporate 4 types of Vitamin C instead of using just one type?

The only form of Vitamin C that can be used by the human body is L-ascorbic Acid. However, it oxidizes easily and is water soluble, meaning the body does not store any excess amount of Vitamin C that it cannot immediately utilise. In order to create a product in which efficacy is optimised throughout shelf-life as well as prolonging its activity in the body, a blend of a few stabilized Vitamin C with added benefits is incorporated with L-ascorbic Acid, in which the mixture work in synergy to yield its benefits while ensuring the product delivers its performance until every last drop.

Can pregnant or nursing women use this product?

Yes; while there are no studies that suggest topical Vitamin C products below 20% shall not be used during pregnancy or nursing, we suggest you to consult your physician before use.

Can people with sensitive and oil-prone skin use this product?

Yes, but do find the use suggestions below:
Sensitive prone skin: patch test before use, and start off by diluting 1-2 drops into 2-3 drops of Skin Need water-basedd serum and use on alternative nights. Only increase dosage or use frequency if skin does not react negatively.
Oil prone skin: since one form of Vitamin C - Tetrahexyldecyl Ascorbate - in this product is not water soluble, the product may seem slightly rich to very oily skin. The slight richness can be completely countered by diluting 1-2 drops into 2-3 drops of Skin Need water-basedd serum for an overall fresher rheology.

If I want to treat premature ageing and hyperpigmentation, what are the best ways to use this product and until how long will I see results?

As ageing and hyperpigmentation are triggered by a variety of factors and thus a well-rounded defence system should be employed to counter those actions, progressively incorporating the Skin Need Fortified Ferulic Serum and Skin Need Retinol and Resveratrol Cream into your routine on alternating mornings and evenings can optimize these actions. Since use combinations, amounts and frequency depend on your skin type + skin problem combination, I recommend that you talk to a Skin Need Skin Consultant to learn about the best plan for your case! While you will see improvements in as little as 7 days, it is recommended to use for at least 28 days to see more substantial results.
