At Meticulous, we formulate for longevity, performance, and results — not trends. That’s why our Longevity Hybrid Defense Serum features a four-part vitamin C system, carefully curated to deliver targeted skin benefits on multiple levels.
While many brands rely on a single form of vitamin C, we go further — combining L-ascorbic acid, 3-glycerol ascorbate, tetrahexyldecyl ascorbate, and magnesium ascorbyl phosphate for a comprehensive approach to brightening, collagen support, antioxidant defense, and skin longevity.
Each of these forms brings unique strengths. Together, they deliver a
more potent, more bioavailable, and more skin-friendly experience.
L-Ascorbic Acid – The Gold Standard
L-ascorbic acid is the most biologically active form of vitamin C — a potent antioxidant known to stimulate collagen production, neutralize free radicals, and brighten uneven skin tone. However, it’s also notoriously unstable, which is why we pair it with fulvic acid and complementary C derivatives to enhance absorption and mitigate oxidative breakdown.
What this means for your skin:
1. Brighter, more even complexion
2. Boosted collagen for firmness and elasticity
3. Strong antioxidant protection against environmental damage
3-Glycerol Ascorbate – The Hydrating Brightener
3-glycerol ascorbate is a newer, water-soluble vitamin C derivative
bonded to glycerol. This combination enhances skin penetration while also boosting hydration. It offers a more stable delivery of vitamin C, reducing irritation while increasing glow.
What this means for your skin:
1. Enhanced moisture retention
2. Gentle brightening, even for sensitive skin
3. Softer texture and improved tone
Tetrahexyldecyl Ascorbate – The Deep Defender
This oil-soluble vitamin C is uniquely able to penetrate the lipid layers of the skin, delivering antioxidant power deeper than traditional forms. It’s exceptionally stable and effective in reducing fine lines, dark spots, and long-term oxidative damage.
What this means for your skin:
1. Reduced redness and sensitivity
2. Strengthened skin barrier
3. Balanced, healthy glow
Magnesium Ascorbyl Phosphate – The Calmer
Known for its anti-inflammatory properties, magnesium ascorbyl
phosphate is a water-soluble C derivative ideal for sensitive or acne- prone skin. It helps calm irritation, boosts hydration, and supports overall skin resilience.
What this means for your skin:
1. Reduced redness and sensitivity
2. Strengthened skin barrier
3. Balanced, healthy glow
The Synergy Behind the Science
These four forms of vitamin C work synergistically in the Longevity Hybrid Defense Serum, creating a hybrid antioxidant matrix that acts on both the surface and deep layers of the skin. And thanks to our
Fulvic Acid Trace Mineral Complex, each C is more bioavailable — meaning your skin actually absorbs and utilizes them more efficiently. This isn’t just skincare — it’s topical supplementation engineered for
performance.
