Introduction
Vitamin C serums remain one of the fastest-growing categories in personal care, loved for their brightening, antioxidant, and anti-aging benefits. Among the successful case studies in the market, Tree of Life stands out as a brand known for clean formulas and visible clinical results.
Today, we are proud to share how our R&D and full-service OEM/ODM capabilities supported a brand in developing their Vitamin C Serum inspired by the Tree of Life concept — a lightweight, stable, and high-efficacy formulation designed for modern consumers.
This case study shows how we work closely with global brand owners to transform ideas into ready-to-launch products, supported by professional formulation, stability testing, packaging guidance, and manufacturing.
Understanding the Tree of Life Approach to Vitamin C
Tree of Life has long emphasized:
-
Clean & safe ingredients
-
Visible skincare results
-
High-quality active ingredients
-
Consumer-friendly textures
-
Transparent formulation philosophy
These principles guided our collaborative development process. The goal was to create a Vitamin C essence that is stable, gentle, and effective, delivering noticeable skin improvement without irritation.
Our R&D Approach to Creating a Market-Ready Vitamin C Serum
✔ 1. Selecting a Stable & Effective Vitamin C Form
Traditional L-ascorbic acid oxidizes quickly, turning brown and losing effectiveness. To avoid this, we recommended using stable Vitamin C derivatives, such as:
-
Sodium Ascorbyl Phosphate (SAP)
-
3-O-Ethyl Ascorbic Acid
-
Magnesium Ascorbyl Phosphate (MAP)
These ingredients maintain brightening power while offering longer shelf life and lower irritation, ideal for mass-market consumers.
✔ 2. Building a Multi-Tasking Formula
The final essence includes a synergistic blend of high-performance actives:
-
Vitamin C Derivative – brightens and evens skin tone
-
Hyaluronic Acid – hydrates and plumps
-
Vitamin E – enhances antioxidant stability
-
Niacinamide (optional) – strengthens skin barrier
-
Botanical Extracts – soothes, provides natural anti-oxidation
This combination ensures both instant hydration and long-term radiance enhancement, aligning with Tree of Life’s clean-beauty standards.
✔ 3. Texture & Skin Feel Optimization
Consumers love lightweight serums that absorb quickly. Our R&D team adjusted:
-
Viscosity
-
Spreadability
-
Absorption rate
-
Finish (non-sticky, non-oily)
Multiple panels and iterations ensured the final serum matched the sensory profile of leading Vitamin C products in the US and EU markets.
Packaging Guidance for Maximum Stability
Since Vitamin C can be sensitive to:
-
Light
-
Oxygen
-
Heat
We guided the brand to choose amber glass bottles, air-tight pumps, and UV-blocking packaging materials. We also tested:
-
Dropper vs. pump compatibility
-
Material interactions
-
Sealing performance
-
Transportation stability
These steps ensured excellent anti-oxidation protection and longterm product freshness.
Full Manufacturing & Quality Control
Our production process follows a strict OEM/ODM quality system:
✔ Incoming raw material testing
Verifying every ingredient meets purity and safety standards.
✔ Controlled production in ISO-GMP workshops
Ensuring consistency for every batch.
✔ Microbiological & stability testing
Including accelerated aging for formula robustness.
✔ Final filling & packaging inspection
Ensuring correct fill volume, sealing, labelling, and overall appearance.
These quality practices give brand owners complete confidence before launching to market.
