Frequently asked questions
What is L-ascorbic acid?

L-ascorbic acid is the purest and most bioavailable form of vitamin C used in skincare. It is a water-soluble antioxidant that works at a cellular level to brighten the skin, stimulate collagen production, and protect against environmental damage. It is most effective when applied consistently and combined with SPF during the day.
What are the benefits of L-ascorbic acid for skin?

L-ascorbic acid offers a wide range of skin benefits including brightening dull complexions, fading dark spots, boosting collagen synthesis, improving skin firmness, and neutralising free radicals caused by UV exposure and pollution. With consistent use, skin appears more radiant, even, and youthful. It is most effective when applied consistently and combined with SPF during the day.
Is L-ascorbic acid suitable for all skin types?

L-ascorbic acid can be used across most skin types; those with sensitive or reactive skin should start with a lower concentration and gradually build up tolerance. Its brightening and protective properties make it a valuable addition to any routine when introduced carefully. It is most effective when applied consistently and combined with SPF during the day.
What percentage of L-ascorbic acid is most effective?

Concentrations between 10% and 20% are generally considered most effective for visible results, with 15% being a well-researched sweet spot that balances efficacy with tolerability. Higher concentrations do not always deliver better results and may increase the likelihood of irritation for sensitive skin types. It is most effective when applied consistently and combined with SPF during the day.
How do I use L-ascorbic acid in my skincare routine?

L-ascorbic acid should be applied to clean, dry skin in the morning before moisturiser and SPF. Allow it to absorb fully before layering other products to maximise its antioxidant benefits throughout the day. It is most effective when applied consistently and combined with SPF during the day.
Can L-ascorbic acid help with hyperpigmentation?

Yes, L-ascorbic acid is one of the most clinically studied ingredients for reducing hyperpigmentation. It works by inhibiting melanin production, which helps to fade existing dark spots and prevent new ones from forming, resulting in a more even and luminous complexion over time. It is most effective when applied consistently and combined with SPF during the day.
Can I use L-ascorbic acid with other active ingredients?

L-ascorbic acid pairs well with vitamin E and ferulic acid, which enhance its stability and antioxidant performance. It can also be used alongside hyaluronic acid and niacinamide, it is best to avoid layering it directly with strong exfoliants or retinol in the same routine to prevent irritation. It is most effective when applied consistently and combined with SPF during the day.
Does L-ascorbic acid help with collagen production?

Yes, L-ascorbic acid is essential for collagen synthesis as it acts as a cofactor in the production of procollagen, the building block of firm, structured skin. Regular use helps to maintain skin density, reduce the appearance of fine lines, and support long-term elasticity. It is most effective when applied consistently and combined with SPF during the day.
Why does L-ascorbic acid oxidise and how do I prevent it?

L-ascorbic acid is inherently unstable and can oxidise when exposed to light, air, and heat, turning the formula yellow or orange and reducing its effectiveness. To preserve potency, store your product in a cool, dark place, ensure the lid is tightly closed after use, and opt for formulas housed in opaque or airtight packaging. It is most effective when applied consistently and combined w
How long until I see results from L-ascorbic acid?

With consistent use, results from L-ascorbic acid can be seen in as little as four weeks. In the first two weeks, skin begins to look brighter and more radiant as the antioxidant properties take effect and dullness is visibly reduced. By week four, improvements in pigmentation and firmness become more apparent, with dark spots fading and skin feeling more structured and resilient. It is most effective when applied consistently and combined with SPF during the day.
