The new C15 Super Booster features the same 15% pure vitamin C in a formula designed for improved stability and a more consistent experience from first use to last drop. 

We streamlined the formula to focus on the ingredients that matter most, helping minimise oxidation and improve how the product feels on skin—lightweight, fast-absorbing, and easy to layer. The result is a vitamin C booster that helps improve radiance and remains suitable for everyday use. 

This vitamin C booster helps brighten dull skin, improve the look of uneven tone, and support firmer-looking skin over time. Its antioxidant benefits also help defend against environmental stressors, leaving skin looking more radiant and refreshed.

C15 Super Booster is suitable for all skin types seeking a daily dose of glow, antioxidant defense, and for targeting concerns such as minor discolouration, dullness, and fine lines.

Skin looks instantly brighter from the first application. Within one week, hydration is visibly improved, and after four weeks, skin feels smoother, tone appears more even, and dullness is noticeably reduced—while fine lines look softened. With continued twice-daily use, skin becomes visibly brighter and more radiant over time.

No, C15 does not contain fragrance, dyes ,silicones (or siloxanes),orparabens. Yes, it is vegan.

C15 Super Booster contains 15% pure vitamin C (ascorbic acid) and is a good option for daily use to help improve the look of dullness and uneven tone. It can be used on its own or mixed into a serum or non-SPF moisturizer. 

25% Vitamin C + Glutathione Clinical Serum uses vitamin C derivatives and is better suited for more advanced concerns like uneven tone, discolouration, and loss of firmness. You can use either product on its own or both in the same routine, depending on your skin concerns and tolerance. If using both, start slowly and adjust as needed.  

The C15 Super Booster pairs 15% stabilised vitamin C, a superstar antioxidant that visibly evens skin tone and defends against free radicals with two powerhouse partners: ferulic acid, which stabilises vitamin C and helps defend against discolouration, and vitamin E, one of the most well-researched antioxidants in skincare, known to protect skin and boost overall formula efficacy. Together, this trio works to visibly brighten skin and even your complexion.

Yes, and we recommend it. Vitamin C and sunscreen complement each other for daytime use. Apply the C15 Super Booster after cleansing, then finish your morning routine with a moisturiser rated SPF 30 or greater. If you prefer to mix the booster into a moisturiser, choose a non-SPF moisturiser so you do not dilute your sun protection.

Yes. To get the best results, we recommend using vitamin C in the morning (to brighten and even skin tone) and retinol at night (to smooth skin and target signs of ageing). Introduce them gradually to ensure your skin tolerates the combination well. 

Yes. These two ingredients work well together and can be used in the same routine. Vitamin C boosts radiance and fades discolouration, while niacinamide calms the skin and visibly minimises pore size. This combination is generally well-tolerated, but it's always best to start slowly if you have sensitive skin.

This vitamin C formula does not contain ingredients typically restricted during pregnancy. However, if you have questions about starting a new product while pregnant or breastfeeding, speak with your healthcare provider. 

C15 Super Booster can range from clear to pale peach or amber. That color variation is normal, and vitamin C may darken over time.  

For best results, store your C15 Super Booster in a cool, dark place away from direct sunlight and excess heat. Keep the cap tightly closed when not in use. Once opened, using it within 3 months helps ensure optimal freshness and performance. 

Tip: Use a Sharpie-like marker to write the date you opened it on the bottom of the bottle to help keep track. 

A booster is more concentrated and designed to target a specific concern. A serum usually contains a blend of ingredients for broader benefits. C15 Super Booster delivers 15% pure vitamin C and can be used on its own or mixed into a serum or non-SPF moisturiser. Our 25%vitamin C serum combines vitamin C derivatives with other supportive ingredients for more comprehensive care. 

Yes. The C15 Super Booster is designed to work well with most skincare products without reducing its effectiveness. The only ingredient to keep separate is copper peptides, as they can make pure vitamin C less effective. If you use both, apply one in the morning and the other at night. Otherwise, vitamin C pairs well with a wide range of ingredients, including antioxidants, niacinamide, AHA, BHA, and PHA. You can use it on its own or mix a few drops into your favorite serum or non-SPF moisturiser for added convenience.
