Dipalmitoyl Hydroxyproline

Dipalmitoyl hydroxyproline is branded as Anallerg® -- DH. Hydroxyproline is the primary amino acid in the composition of skin collagen, with two lipophilic palmitic acid groups enhancing its skin permeability. Palmitoylated hydroxyproline is an amphiphilic molecule highly compatible with the skin. Dipalmitoyl hydroxyproline can act as a bio-shaping agent for hydroxyproline, allowing hydroxyproline to be directly supplemented through the skin to reach the target and exert its effects. Enzymes related to lipid metabolism in the stratum corneum of the skin can hydrolyze palmitoyl amino acids, releasing hydroxyproline, while the fatty acid groups remain on the skin surface to form a lipid protective layer. Extensive scientific experiments have demonstrated that dipalmitoyl hydroxyproline exhibits excellent anti-aging and firming effects, making it a remarkably effective anti-aging ingredient.

Anallerg® -HDA

Anallerg® -HDA (10-Hydroxydecanoic acid) is one of the major hydroxy fatty acids found in royal jelly and serves as a natural precursor to 10-hydroxy-2-decenoic acid. It offers anti-inflammatory, antioxidant, anti-wrinkle benefits, and helps regulate sebum secretion in sebocytes.

Anallerg® -Mulan

Anallerg® -Mulan (Tetrahydromagnanol) is a highly effective whitening ingredient derived from the plant magnolia. Tetrahydromagnanol can effectively downregulate melanin synthesis by inhibiting the maturation of tyrosinase, promoting tyrosinase degradation, and inhibiting the transfer of tyrosinase to melanosomes, thereby improving pigmentation and uneven skin tone. The core advantage of Mulan® lies in its powerful whitening effect and its different anti-melanin mechanism from traditional whitening ingredients (such as arbutin, glabridin, etc.). It is low-dose, high-efficiency, and cost-effective.

Anallerg® -Mulan-5A

Anallerg®-Mulan-5A (Tetrahydromagnanol) is a highly effective whitening ingredient derived from the plant magnolia. Tetrahydromagnanol can effectively downregulate melanin synthesis by inhibiting the maturation of tyrosinase, promoting tyrosinase degradation, and inhibiting the transfer of tyrosinase to melanosomes, thereby improving pigmentation and uneven skin tone. The core advantage of Mulan® lies in its powerful whitening effect and its different anti-melanin mechanism from traditional whitening ingredients (such as arbutin, glabridin, etc.). It is low-dose, high-efficiency, and cost-effective.

Anallerg® -Qingzhao

Anallerg® -Qingzhao (Acetyl Glutathione) is a precursor of glutathione, with higher stability and bioavailability compared to glutathione. As an antioxidant, it helps neutralize free radicals and reduce oxidative stress-induced damage to cells. Compliance Highlights Unavailable
