NanoActive® RAL (Liposomal Retinal) Advanced Vitamin A Technology for High-Performance Skin Care
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.

Scar-Zero
Scar-Zero is a new scar repair product that can effectively prevent and treat skin scars. With advanced genomics and proteomics technology, the product is manufactured by extracting core factors related to skin repair in human proteins through the online activity screening technology and genetic recombination technology. Various factors cooperate and restrict each other, forming a complex regulatory network, regulating cells to maintain normal oxidative stress levels, and controlling micro-inflammation in the skin. It guides the proliferation of epidermal and dermal cells, and prolongs the self-regenerating function of keratinocytes to fundamentally reverse the aging process of skin cells. The unique repair factor can help the skin produce a large number of active matters, effectively control the micro-inflammation in the skin, repair blood vessels and dermal cells, make the skin hydrated and translucent, and improve the skin gloss, softness and tenderness to render an effect of inverse age.
