Vitamin C contributes to normal collagen formation for the normal function of skin. It also contributes to the protection of cells from oxidative stress.
What it is
Vitamin C (ascorbic acid) is an essential, water-soluble nutrient that plays a central role in normal collagen formation and cellular antioxidant defence. In skin, it supports the biochemical processes that stabilise collagen and help protect cells from oxidative stress caused by daily environmental exposures.
Because the body does not store vitamin C in large amounts, consistent daily intake is required to support these functions.
How it works
Inside the dermis, vitamin C supports the enzymes responsible for collagen synthesis and stabilisation, helping maintain skin elasticity and firmness. It also contributes to antioxidant balance by neutralising reactive oxygen species and supporting the regeneration of oxidised vitamin E.
This inside-out role complements topical vitamin C, which primarily acts at the surface. Together, oral and topical vitamin C support both the living skin and the outer layers exposed to daily stress.
Why morning
Vitamin C is water-soluble and not stored long-term. Taking it in the morning aligns intake with daytime exposure to UV light, pollution, and metabolic activity, when oxidative stress tends to be higher.
For best coverage, pair your oral dose with a topical antioxidant serum and SPF. This dual approach supports both surface and deeper skin layers throughout the day.
Benefits
-
Contributes to normal collagen formation for the normal function of skin
-
Helps protect cells from oxidative stress
-
Complements hyaluronic acid (hydration), ceramides (skin-barrier lipids), and REGGENERATE™ (dermal matrix support)
Why it’s in BOOST
BOOST is designed as an inside-out skin routine, not a single-ingredient solution. Vitamin C plays a coordinating role by supporting collagen formation while reinforcing antioxidant protection across the dermal matrix.
In BOOST, vitamin C works alongside SkinAx²™ Lift (collagen defence and synthesis support), REGGENERATE™ (structural dermal components), ceramides (barrier lipids), hyaluronic acid (hydration), and astaxanthin (lipid-phase antioxidant). Together, these ingredients address skin structure, protection, and resilience as one integrated system.

Supplement vs topical (they’re complementary)
Topical vitamin C mainly acts at the surface, supporting tone, brightness, and protection in photo-exposed layers. Oral vitamin C works within the living skin, supporting collagen formation and antioxidant defence deeper in the dermis.
Using both is the smart pair: take BOOST in the morning, then apply your vitamin C serum and SPF for surface-level protection.
Dosage context
What BOOST provides
80 mg vitamin C per day (per 2-capsule serving), providing 100% of the EU NRV.
What research uses
Typical daily intakes range from ~75–200 mg/day from diet and supplements. Skin- and collagen-focused studies commonly fall within this range, sometimes higher when combined with other actives.
How this fits
80 mg/day reliably supports normal collagen formation and protection of cells from oxidative stress, while fitting cleanly within a balanced, multi-ingredient skin formula.

FAQs
Is 80 mg enough?
Yes for daily support, especially alongside a balanced diet. Plasma vitamin C reaches a plateau with moderate intakes; more isn’t always better.
Do I need oral vitamin C if I already use a vitamin C serum?
Yes — they work in different places. The serum supports brightness and protection at the surface. Oral vitamin C supports collagen formation and antioxidant balance within the living skin. Together they cover both layers.
What else in BOOST helps with antioxidant defense?
BOOST also includes astaxanthin and polyphenols (via SkinAx²™), which support daily oxidative-stress defense. They complement vitamin C rather than replace it.
Any safety notes?
Generally well tolerated at typical amounts. If you have kidney stone history or take specific medications, speak with your clinician.
