Company & Brand Background
PuriPharm Co. Ltd. is a science-driven company specializing in the research, development, and commercialization of high-performance functional bioactive ingredients. With a strong foundation in pharmaceutical science, biotechnology, and advanced formulation technologies, PuriPharm is dedicated to delivering safe, effective, and innovative active ingredient solutions for the global cosmetics, personal care, and biomedical industries.
PuriPharm operates two core product platforms:
• PuriActives® – a portfolio of high-quality functional bioactives derived from natural, bio-based, and scientifically validated sources.
• NanoActive® – an advanced nano-delivery ingredient platform designed to enhance the stability, bioavailability, and efficacy of sensitive active compounds through cutting-edge encapsulation technologies.
NanoActive® RAL (Liposomal Retinal) is a flagship product of the NanoActive® series, representing PuriPharm’s expertise in vitamin A chemistry, lipid delivery systems, and skin bioavailability optimization.
Retinal, also known as retinaldehyde (RAL), is a highly active form of vitamin A and a direct biochemical precursor of retinoic acid, the biologically active molecule responsible for many of vitamin A’s well-known skin benefits.
Unlike retinol, which requires a two-step enzymatic conversion process in the skin, retinal converts to retinoic acid in only one step. As a result, retinal delivers faster and more efficient biological activity at significantly lower concentrations.
Scientific and clinical studies have demonstrated that:
• Retinal converts to retinoic acid approximately 11 times faster than retinol
• Retinal offers efficacy comparable to retinoic acid but with significantly improved skin tolerance
• Retinal provides powerful anti-aging, skin-renewing, and collagen-stimulating effects with reduced irritation
For these reasons, retinal is widely recognized as one of the most advanced and effective vitamin A forms available for modern skin care formulations.
Why Choose Retinal Instead of Retinol?
Although retinol has long been used in cosmetic formulations, it presents several inherent limitations, including instability, oxidation, discoloration, and slow biological conversion.
Retinal offers distinct advantages:
• Faster efficacy – 11-fold faster conversion to retinoic acid compared with retinol
• Higher biological efficiency – closer to retinoic acid in the vitamin A metabolic pathway
• Improved skin tolerance – lower irritation potential compared with retinoic acid
• Broader functionality – supports anti-aging, acne control, skin tone improvement, and barrier repair
However, retinal itself is a chemically sensitive molecule that is prone to oxidation, light degradation, and discoloration. These challenges have historically limited its widespread use in cosmetic formulations.
NanoActive® RAL: Liposomal Retinal Technology
NanoActive® RAL overcomes the traditional limitations of retinal through an advanced liposomal nano-delivery system, enabling formulators to fully unlock the benefits of retinal in a stable, effective, and user-friendly form.
NanoActive® RAL is a lipid-encapsulated retinal, engineered using phospholipid bilayer technology that mimics the structure of biological cell membranes. This delivery system provides comprehensive protection and controlled release of retinal in the skin.
Key Features of NanoActive® RAL
• High stability – protected from oxidation, light exposure, and thermal degradation
• No discoloration – maintains formulation clarity and color stability over time
• Enhanced skin absorption – liposomal structure improves penetration and bioavailability
• Controlled release – gradual delivery minimizes irritation while maximizing efficacy
• Superior compatibility – easy to formulate into a wide range of cosmetic systems
Through nano-encapsulation, NanoActive® RAL ensures that retinal remains active, effective, and safe throughout the product’s shelf life and during skin application.
11 Times Faster Conversion to Retinoic Acid
One of the most important advantages of NanoActive® RAL is the intrinsic metabolic efficiency of retinal.
In the skin:
• Retinol → Retinal → Retinoic Acid (two-step conversion)
• Retinal → Retinoic Acid (one-step conversion)
This simplified pathway allows retinal to deliver results approximately 11 times faster than retinol, leading to quicker improvements in skin texture, tone, and visible signs of aging.
Because NanoActive® RAL enhances retinal delivery and stability, this rapid conversion can occur more efficiently and consistently within the skin.
Skin Benefits of NanoActive® RAL
NanoActive® RAL delivers a comprehensive range of clinically supported skin benefits:
Anti-Aging & Wrinkle Reduction
• Stimulates collagen and elastin synthesis
• Improves skin firmness, elasticity, and density
• Reduces the appearance of fine lines and wrinkles
Skin Renewal & Texture Improvement
• Accelerates epidermal cell turnover
• Smooths rough skin texture
• Promotes a more even and refined complexion
Brightening & Tone Correction
• Inhibits tyrosinase activity and melanin formation
• Enhances skin radiance and uniformity
• Helps fade hyperpigmentation and discoloration
Acne & Blemish Control
• Exhibits direct antibacterial activity against acne-causing bacteria
• Regulates sebum production
• Supports pore refinement and blemish recovery
Barrier Support & Repair
• Improves skin barrier integrity
• Enhances resilience against environmental stressors
• Supports long-term skin health and comfort
Superior Stability and Color Performance
Traditional retinal and retinol formulations often suffer from:
• Rapid degradation
• Yellowing or browning over time
• Loss of activity during storage
NanoActive® RAL is specifically designed to address these issues. The liposomal encapsulation effectively isolates retinal from environmental stress factors, resulting in:
• Excellent formulation stability
• Minimal color change over time
• Consistent performance throughout shelf life
This makes NanoActive® RAL ideal for premium skin care products where visual appearance, product consistency, and long-term efficacy are critical.
Easy Absorption & Skin Compatibility
The phospholipid-based nano-carriers used in NanoActive® RAL closely resemble the lipid structure of human skin. This biomimetic design allows for:
• Improved skin affinity
• Efficient penetration through the stratum corneum
• Targeted delivery to deeper skin layers
As a result, NanoActive® RAL is easily absorbed, non-greasy, and well tolerated, even in long-term use formulations.
NanoActive® RAL is suitable for a wide range of cosmetic and personal care applications, including:
• Anti-aging serums and creams
• Brightening and skin renewal products
• Acne treatment formulations
• Eye care products
• Barrier repair and post-treatment care
Its excellent compatibility allows formulators to incorporate NanoActive® RAL into emulsions, gels, lotions, and advanced delivery systems with ease.
A New Generation of Vitamin A Actives
By combining the proven biological power of retinal with state-of-the-art nano-delivery technology, NanoActive® RAL represents a new generation of vitamin A active ingredients.
It offers:
• Faster results than retinol
• Better tolerance than retinoic acid
• Greater stability than conventional retinal
• Enhanced user experience and formulation reliability
Conclusion
NanoActive® RAL (Liposomal Retinal) embodies PuriPharm Co. Ltd.’s commitment to scientific excellence, innovation, and performance. As a key product within the NanoActive® platform and a natural extension of the PuriActives® philosophy, NanoActive® RAL provides formulators and brands with a powerful, stable, and advanced vitamin A solution for next-generation skin care.
