Vitamin C for glow, smoother texture & oil balance

Vitamin C Booster is a lightweight daily serum designed to support radiance, smoother-looking skin, refined pores and balanced oil.

Unlike conventional Vitamin C formulas built around L-Ascorbic Acid, 28N takes a different approach.

The formula combines Magnesium Ascorbyl Phosphate (MAP), a stable Vitamin C derivative, with Potassium Azeloyl Diglycinate (PAD) and Tropolone.

Together, these three actives provide antioxidant support while helping:

  • Boost radiance and glow
  • Refine the appearance of pores
  • Smooth skin texture
  • Balance excess oil

Designed for sensitive, oily and combination skin. Optimised for daily use.

28N Vitamin C Booster active system with MAP vitamin C derivative, PAD azelaic acid derivative and Tropolone

Vitamin C, Formulated Differently.

Vitamin C Booster takes a different approach to traditional L-Ascorbic Acid formulas.

It combines Magnesium Ascorbyl Phosphate (MAP), a stable Vitamin C derivative, with Potassium Azeloyl Diglycinate (PAD) and Tropolone.

Each active has a distinct role: MAP supports radiance and antioxidant defence, PAD helps balance excess oil and refine the appearance of pores, while Tropolone complements the antioxidant-focused formula.

Three complementary actives. One considered daily formula.

28N Vitamin C Booster with Potassium Azeloyl Diglycinate to help balance excess oil and refine the look of pores

More Than Vitamin C.

Vitamin C Booster was designed to do more than support radiance.

Potassium Azeloyl Diglycinate (PAD), a water-soluble azelaic acid derivative, helps balance excess oil and refine the appearance of pores.

Combined with Magnesium Ascorbyl Phosphate (MAP), it supports a smoother, more radiant and balanced-looking complexion—making Vitamin C Booster particularly relevant for oily and combination skin.

This is also why Vitamin C Booster forms part of the 28N Oil Control Duo.

28N Vitamin C Booster in-vivo tested results showing improvements in skin gloss and wrinkle measures when paired with A⁶ or B⁶

A Booster by Design.

Vitamin C Booster can be used alone, but it was also designed to complement 28N's targeted formulas.

In 28-day in-vivo testing, Vitamin C Booster + A⁶ Anti-Ageing Formula achieved a 47.47% reduction in visible wrinkle area and a 44.76% reduction in visible wrinkle depth.

With Vitamin C Booster + B⁶ Brightening Formula, skin gloss increased by 30.69% after 28 days.

Use after cleansing and before your targeted serum, or pre-blend the products in the palm before application.

Frequently Asked Questions

What makes 28N Vitamin C Booster different from a traditional Vitamin C serum?

Vitamin C Booster uses Magnesium Ascorbyl Phosphate (MAP), a stable Vitamin C derivative, alongside Potassium Azeloyl Diglycinate (PAD) and Tropolone. Rather than focusing on Vitamin C alone, the formula is designed to support radiance, smoother-looking skin, antioxidant defence and oil balance.

Is Vitamin C Booster suitable for oily or combination skin?

Yes. Vitamin C Booster was specifically formulated with Potassium Azeloyl Diglycinate (PAD), an azelaic acid derivative that helps balance excess oil and refine the appearance of pores. This makes it particularly relevant for oily and combination skin while still supporting radiance and antioxidant care.

Does Vitamin C Booster help with the appearance of pores?

Yes. Potassium Azeloyl Diglycinate (PAD) helps balance excess oil and refine the appearance of pores, supporting a smoother, more balanced-looking complexion.

Is Vitamin C Booster the same as B⁶ Brightening Formula?

No. They have different roles in the 28N range. Vitamin C Booster focuses on glow, smoother-looking skin, oil balance and antioxidant support, while B⁶ Brightening Formula is the targeted formula for uneven tone, pigmentation and dark spots. They can also be used together.

Why is it called a Vitamin C “Booster”?

Vitamin C Booster can be used on its own, but it was also designed to complement 28N's targeted formulas. In 28-day in-vivo testing, Vitamin C Booster used with A⁶ Anti-Ageing Formula achieved a 47.47% reduction in visible wrinkle area and a 44.76% reduction in visible wrinkle depth. When used with B⁶ Brightening Formula, skin gloss increased by 30.69%.

Can I use Vitamin C Booster on its own?

Yes. Vitamin C Booster can be used independently as part of your daily routine to support radiance, smoother-looking skin, oil balance and antioxidant defence. Pairing it with A⁶ or B⁶ is optional.

Can I use Vitamin C Booster with A⁶ and B⁶?

Yes. Vitamin C Booster was designed to complement both formulas. Pair it with A⁶ when your primary focus is visible signs of ageing, or B⁶ when targeting uneven tone and pigmentation. If using multiple active formulas, introduce them gradually according to your skin's tolerance.

Does Vitamin C Booster contain L-Ascorbic Acid?

No. The formula uses Magnesium Ascorbyl Phosphate (MAP), a stable Vitamin C derivative, rather than relying on L-Ascorbic Acid. MAP was selected as part of a multi-active formula designed for daily use.

Is Vitamin C Booster naturally derived?

Vitamin C Booster contains 98.35% ingredients of natural origin, calculated according to ISO 16128.
