Synoxyl® HSS is a biodegradable SPF booster and photostabilizer, ideal for formulating broad-spectrum sunscreens free from octocrylene and oxybenzone. Inspired by the molecular structure of ginger, Synoxyl® HSS is designed to enhance SPF performance, protect light-sensitive ingredients from photodegradation, and safeguard the skin by inhibiting upstream reactive oxygen species (ROS) cascades.

This unique compound delivers in-vivo SPF boosting of ≥50% in both organic and inorganic sunscreen formulations—without contributing to SPF on its own—making it a cost-effective, eco-friendly solution for next-generation sun care products. Its photostabilizing effect stems from triplet-state energy transfer from avobenzone and light-triggered reactions that preserve key chromophores, ensuring long-lasting UV protection and formulation integrity.

Key Benefits:

• Biodegradable and environmentally conscious
• Simplifies the preparation of eco-friendly sunscreens
• Significantly boosts SPF in vivo
• Stabilizes UV filters like avobenzone
• Ideal for octocrylene- and oxybenzone-free formulations

Synoxyl® AZ is a high-purity (≥99%) multi-targeted anti-aging active developed to both prevent premature skin aging and visibly reverse signs of photo-damage. Designed to work proactively, Synoxyl® AZ helps protect the skin from environmental stressors while supporting its natural ability to preserve and repair the extracellular matrix (ECM)—a critical component for maintaining firmness, elasticity, and overall skin health.

In addition to its anti-aging efficacy, Synoxyl® AZ promotes microbiome balance by enhancing microbial diversity and stimulating the growth of beneficial skin flora such as Staphylococcus epidermidis by over 20%, contributing to a more resilient, healthier-looking complexion.

Sytenol® A is the first natural alternative to retinol, offering comparable clinical performance without the irritation, dryness, or sensitivity often associated with traditional retinoids.

With a purity of ≥99%, it is both photochemically and hydrolytically stable, allowing for safe daytime use without photosensitivity concerns. Extensive studies show that Sytenol® A modulates retinoid-binding and metabolizing genes, significantly improves dermal and dermo-epidermal junction proteins, and stimulates Collagen I, III, and IV production for stronger, firmer skin. It also enhances hydration by upregulating hyaluronic acid and aquaporin 3 synthesis.

Highlights:

• As a plant-based compound, it offers a gentler alternative to synthetic retinol, with a lower risk of irritation.
• In a 12-week study, bakuchiol users reported up to 5 times less facial skin scaling and stinging than retinol users.
• The same study showed a 59% reduction in hyperpigmentation, compared to only a 44% reduction in the retinol group.
• Unlike some retinoids, it is photostable, i.e., it’s stable when exposed to light, making it suitable for daytime use.

In the years since the team at Sytheon, now part of Hallstar, introduced Sytenol® A Bakuchiol to the world, they have conducted rigorous research and published extensive data on its multiple benefit,s ensuring scientific precision, reliability, and proven safety.

Clinically, Sytenol® A delivers visible reduction in skin roughness, dryness, fine lines, and wrinkles, while improving tone, elasticity, firmness, radiance, and brightness — redefining what’s possible with natural skincare. Suggested use levels are 0.5 to 1%.
