Ectoine, also known as 1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid, is a natural compound derived from amino acids. It acts as a protective substance, offering excellent hydrophilicity. It forms a stable protective film around skin cells and proteins by regulating osmotic pressure, providing soothing and calming effects for irritated or damaged skin.

It exhibits strong protective effects on DNA, enzymes, proteins, nucleic acids, cell membranes, and overall cellular integrity in various adverse conditions, including cold, high temperatures, intense UV exposure, dry environments, high salinity, extreme pH levels, high pressure, and radiation.

In the skincare industry, it offers long-lasting moisturization, anti-allergy properties, and anti-aging benefits. In medicine, it finds applications in treating conditions such as eczema, neurodermatitis, and other skin disorders. It is particularly suitable for treating specific infantile skin conditions.

Sialic acids, also known as N-acetylneuraminic acids (NANA), are a diverse group of 9-carbon carboxylated monosaccharides with a pyranose structure. The most common form is N-acetylneuraminic acid (Neu5Ac).

Sialic acid plays a vital role in promoting neural synapse formation, enhancing memory, and supporting cognitive development. In the field of nutrition, it contributes to fetal brain and retinal development, memory improvement, aids in digestion and absorption, and may potentially help prevent or delay the onset of dementia. In the cosmetics industry, sialic acid offers various benefits, including anti-aging, skin whitening, acne prevention, anti-inflammatory properties, and promoting healthy hair growth.

L-Ergothioneine is a natural amino acid, derived as a thiourea from histidine. It acts as a potent antioxidant, safeguarding human cells. This vital compound plays a significant role in the body, performing functions like free radical elimination, DNA synthesis support, promotion of normal cell growth, and enhancement of cellular immunity.

L-Ergothioneine offers important applications in antioxidant protection, maintenance of redox balance, and detoxification. It finds uses in various fields, including medicine, dietary supplements, and cosmetic ingredients.

Hyaluronic acid, commonly referred to as hyaluronan, is a major constituent of the extracellular matrix and is widely distributed in connective, epithelial, and nervous tissues.

Hyaluronic acid is renowned for its unique biological properties, including non-toxicity, absorbability by the human body, high biocompatibility, and biodegradability. It has extensive applications in the skincare industry, where it excels at improving skin hydration and retaining moisture.

Additionally, low-molecular-weight hyaluronic acid can be absorbed into human tissues through oral consumption, providing its beneficial effects.
