S-DNA APTAMER-1

About S-DNA APTAMER-1

A synthetic single-stranded DNA molecule that folds into a defined 3D structure with high affinity for ascorbic acid (Vitamin C), functioning as an antioxidant and UV filter.

Detailed Analysis

s-DNA Aptamer-1 is a single-stranded DNA molecule produced synthetically, consisting of 32 nucleotides that fold into a well-defined three-dimensional structure. DNA aptamers are a class of functional nucleic acids analogous to antibodies but composed of DNA rather than protein. They exhibit high affinity and specificity for target molecules — in this case, ascorbic acid (Vitamin C). The EU cosmetics regulation does not have specific restrictions on DNA aptamers as a class. Aptamers are considered biocompatible and non-immunogenic (unlike some protein-based recognition molecules). The antioxidant and UV filter functions are consistent with well-established cosmetic benefits of vitamin C itself; the aptamer is designed to bind and stabilize Vitamin C in formulations.

What It Does

Skin Benefits

• ✓ Binds and stabilizes Vitamin C (ascorbic acid) in cosmetic formulations, preserving antioxidant efficacy
• ✓ Single-stranded DNA is non-immunogenic and具有良好的皮肤兼容性
