At Ultraceuticals, we believe that achieving and maintaining great skin requires a holistic, multi-pathway approach that respects the true complexity of the skin. Vitamin C is one of the most scientifically researched ingredients in skincare, yet its benefits are distilled into simple, effective solutions when formulated correctly.
One of our flagship innovations is the Ultra C+ Rejuvenating C Chebula Serum combining 15% pure L-Ascorbic Acid with Chebula Extract and micro-peptides, which help target skin glycation, support collagen, and brighten the complexion making it a true multi-pathway solution for firmer, more luminous skin.
What Does Vitamin C Do for the Skin?
Vitamin C is a multi-pathway powerhouse. When applied topically, it acts across several layers of the skin to support its structure and resilience. Here’s how:
- Stimulates collagen synthesis: Supports skin firmness and elasticity by activating the enzymes responsible for collagen production.
- Brightens and evens tone: Inhibits melanin formation to reduced pigmentation and reveals a more radiant, uniform complexion.
- Provides antioxidant protection: Helps neutralise free radicals from UV exposure and pollution, reducing oxidative stress that accelerates visible aging.
- Protects against glycation: With Chebula Extract, Ultraceuticals’ serum specifically targets sugar ageing that weakens collagen and elastin.
- Supports skin firmness and elasticity: Micro-collagen and micro-elastin peptides reinforce the skin’s structural network, leaving it plump, smooth, and resilient.
How Vitamin C Serums Improve Skin Over Time?
Vitamin C doesn’t deliver overnight miracles, but consistent use can lead to cumulative, visible change:
- Weeks 4–6: Skin looks brighter, hydrated, and more luminous.
- Weeks 8–12: The appearance of fine lines soften, pigmentation diminishes, and texture improves.
- Beyond 12 weeks: Long-term use offers antioxidant protection and collagen support, helping to prevent the signs of premature skin aging, maintaining firmness and resilience.
What to look for in a Vitamin C Serum
- Concentration: 10–20% Vitamin C balances potency with less irritation for skin. Ultra C+ uses 15% L-Ascorbic Acid for optimal effect.
- Formulation: Pure L-Ascorbic Acid is potent but can be unstable. Ultraceuticals stabilises their Vitamin C for maximum potency.
- Multi-pathway support: Ingredients like Chebula Extract and micro-peptides enhance collagen support, helping protect against sugar ageing (Glycation).
How Vitamin C Fits into Your Skincare Routine?
- Apply 4 drops of Ultra C+ Rejuvenating C Chebula Serum to face and neck after cleansing in the morning. Start using on alternate days if your skin is sensitive and increase to daily use.
- Layer under a serum like Ultra B2 Hydrating Serum and follow with a moisturiser like Ultra Hydrating Lotion.
- Always finish with broad-spectrum SPF to protect your skin and prolong results.
