Chemyunion introduces its 2026 "Beyond Time" collection, featuring two actives developed to target melanin regulation in skin and hair. The collection centers on modulating key biological pathways underlying age-related changes in pigmentation.
More specifically, Peptid4 Light MB and BioTech4 AntiGray were designed with mechanistic precision to influence melanogenesis and melanin distribution, while preserving physiological balance, per the company.
Safely Controlling Melanin in Sensitive Skin
Peptid4 Light MB (INCI: Not Provided) is a novel tetrapeptide designed to modulate melanin pathways, with particular application for sensitive and reactive skin. The active targets the Melanocortin-1 receptor (MC1R), simultaneously influencing melanogenesis and inflammatory signaling.
By addressing the interplay between basal inflammation and dysregulated pigmentation, Peptid4 Light MB offers a mechanistically driven alternative to traditional brighteners, aiming to balance skin tone without exacerbating reactivity or compromising epidermal health, according to the company.
By acting upstream in the melanogenesis pathway, Peptid4 Light MB is designed to modulate global skin tone and reduce hyperchromias, supporting a more homogeneous melanin distribution within the epidermis. The mechanism further encourages recovery of skin radiance and transparency often impacted by chronic inflammation and pigment dysregulation.
In addition to its effects on melanogenesis, Peptid4 Light MB has been found to support extracellular matrix integrity, contributing to skin firmness, according to Chemyunion.
Resuming Melanin Production in Gray Hair
BioTech4 AntiGray (INCI: Not Provided) is a biotech-derived postbiotic designed to preserve melanocytic stem cells and protect the pigmentary system against oxidative stress, in turn reducing hair graying.
As the company explains, with age, diminished melanocytic activity leads to reduced melanin synthesis and distribution, resulting in visible hair depigmentation. By modulating the follicular environment and stimulating endogenous melanin production, BioTech4 AntiGray reportedly resumes pigment production and facilitates a more uniform pigment distribution along the hair fiber.
Experimental evidence demonstrates the active provides a measurable decrease in depigmented fibers and improvements in multiple hair quality parameters, per the company. Mechanistically, the active upregulates the expression of key melanogenesis-related genes, permitting a progressive restoration of endogenous hair pigmentation.
This approach is said to provide a research-based framework for modulating age-related pigmentary changes in hair, offering new pathways for scientific study and formulation development.
The company will present these innovations during In-Cosmetics global in Paris.
