MIAMI - s4story -- South Florida, USA — Dec 14, 2025 — 4EverAlive Labs, a U.S.-based cosmetic formulation and small-batch manufacturing laboratory, today announced the development and availability of its new Kojic Acid Advanced Brightening Formulation, engineered specifically for professional spa, aesthetic, and private-label applications.

Designed with a strong emphasis on formulation science, stability, and regulatory awareness, this new system reflects 4EverAlive Labs' ongoing commitment to providing high-performance cosmetic actives without compromising safety, quality, or consistency.

A Technically Driven Approach to Kojic Acid

Kojic acid is widely recognized in cosmetic science for its ability to inhibit tyrosinase activity, thereby reducing excess melanin formation and improving the appearance of hyperpigmentation, age spots, and uneven skin tone. However, its formulation presents well-known challenges related to oxidation, pH sensitivity, and long-term stability.

4EverAlive Labs' new formulation addresses these challenges through:

• Optimized pH control to preserve kojic acid activity while maintaining skin compatibility
• Stabilization strategies to minimize oxidation and color shift over time
• Synergistic support ingredients designed to enhance efficacy and tolerability
• Small-batch manufacturing protocols to ensure batch-to-batch consistency

The result is a professional-grade cosmetic base that can be adapted into serums, creams, lotions, or treatment products depending on spa and brand requirements.

Product Development Without Cost Constraints

"Our philosophy is simple: every formula deserves the same level of precision and care, regardless of production volume," said Javier Guandalini, Founder of 4EverAlive Labs. "This kojic acid formulation reflects how we work — science-first, detail-oriented, and focused on delivering real performance rather than marketing-driven shortcuts."

With more than 20 years of experience in regulated industries including pharmaceuticals and medical devices, 4EverAlive Labs applies a disciplined product development mindset to cosmetics, emphasizing ingredient selection, process control, and documentation aligned with Good Manufacturing Practices (GMP).
