Clinically Tested

We Go Beyond:  Clinically Validated for Safety and Efficacy

Every Soke Hydrogel Treatment Mask undergoes an extensive series of independent tests to verify safety, stability, and performance. These evaluations confirm that our multi-peptide infused hydrogel and firming matrix technology meet the highest cosmetic standards — ensuring visible results with uncompromising safety.

Soke has successfully passed the following cosmetic suitability and stability tests, confirming safety, compliance, and proven efficacy

• USP <51> Preservative Challenge Test:  To confirm lasting product safety, our hydrogel is intentionally exposed to common microorganisms under controlled laboratory conditions. This verifies that Soke’s preservative system effectively prevents bacterial and fungal growth — ensuring every treatment remains safe, stable, and fresh through its full shelf life.
• CA Prop 65 Review:  Soke formulations are reviewed against California’s stringent Proposition 65 requirements, confirming that our hydrogel technology is free from harmful or restricted substances known to cause cancer, reproductive harm, or toxicity.
• Ingredient and Regulatory Copy Review for Cosmetics:  Every ingredient and product claim is examined by a regulatory specialist to ensure accuracy, compliance, and truth in labeling. This guarantees that Soke’s clinical performance statements — including our proven improvements in skin tone, texture, and fine lines — are fully substantiated.
• Freeze-Thaw Stability for Water-Based Products (COA):  To test resilience, Soke’s hydrogel is repeatedly frozen and thawed to simulate shipping and storage extremes. This confirms that our firming matrix retains its integrity, texture, and peptide potency, even when exposed to fluctuating conditions.
• Elevated Temperature Stability for Water-Based Products (COA):  Our hydrogel is subjected to sustained high-temperature conditions in an accelerated aging environment. This ensures that the multi-layered peptide delivery system remains consistent, maintaining the same smooth application and clinical efficacy from the first treatment to the last.
• Heavy Metals by ICP-MS:  Soke’s hydrogel is tested to confirm compliance with cosmetic safety standards. This advanced screening detects trace elements such as lead, mercury, arsenic, and cadmium at parts-per-billion levels. The results verify that Soke meets Health Canada and international cosmetic regulatory limits for heavy metals, ensuring our treatments are safe, pure, and suitable for daily use.
• Human Repeat Insult Patch Test (52 Subjects )  Conducted under supervision, this multi-phase safety study evaluates Soke’s hydrogel for potential irritation and sensitization on human skin. Over a series of applications on 50 volunteers, the formulation demonstrated excellent skin compatibility with no significant signs of irritation among participants. While these results confirm that Soke’s hydrogel is well-tolerated and suitable for most skin types, individual sensitivities can vary, and mild reactions are still possible — as with any cosmetic product.
