Vitamin C Serum with 10% SAP

SAP is a stable, water-soluble derivative of Vitamin C. Unlike traditional L-ascorbic acid serums, it does not require a very low-pH formula to work, which makes it easier to formulate into a comfortable everyday serum.

L-ascorbic acid has the longest history of topical Vitamin C research, while SAP offers a different advantage: greater stability and easier everyday use, particularly for skin that does not enjoy acidic Vitamin C formulas.

SAP is considerably more stable than L-ascorbic acid, but no cosmetic ingredient is completely immune to degradation.

Keep the bottle tightly closed and away from unnecessary heat and direct sunlight. A significant change in the product's usual colour, smell or texture can indicate that something has changed; if you're unsure about your bottle, contact us before continuing to use it.

Yes. Vitamin C and Niacinamide can be used in the same routine.

The old rule that they must always be separated is outdated. You can comfortably use this serum with a Niacinamide serum or a Niacinamide-containing moisturiser if both products suit your skin.

Vitamin C can complement acne treatments such as Salicylic Acid or Azelaic Acid, particularly when you're also trying to improve the marks breakouts leave behind. It can also be used in a retinoid routine.

However, if your skin is sensitive or you're new to skincare, we would not recommend layering several active ingredients in the same routine. Instead an easy approach is Vitamin C in the morning and stronger exfoliating or retinoid treatments at night.

Yes, it can help gradually improve flat post-acne dark marks and uneven tone.

It will not remove true indented or raised acne scars, because those involve structural changes in the skin rather than pigmentation.

For particularly stubborn post-acne pigmentation, a more multi-pathway treatment such as Powerhouse Serum may be more appropriate.

Yes — this is one of the reasons we chose SAP.

The formula is designed as an easy everyday Vitamin C option and does not depend on the very acidic environment used by many L-ascorbic acid serums. It is also lightweight and formulated with Hyaluronic Acid and Allantoin for additional hydration and comfort.

Individual skin can still react to any product, so very reactive skin should introduce it gradually.

Either works, but morning is our preferred time.

Using Vitamin C in the morning gives you antioxidant support during the part of the day when your skin is exposed to UV and other environmental stressors.

Apply it before moisturiser and always finish with sunscreen. Vitamin C complements sunscreen; it does not replace it.

You may start noticing brighter, fresher skin and early improvement in mild marks in around 4–6 weeks, while more noticeable improvement in uneven tone can take 8–12 weeks.

Daily sunscreen makes a major difference when your goal is improving pigmentation.
