Collagen or Amino Acids: Which Skin Booster Is Best?

Collagen vs. Amino Acids: Which Injection Is Right for You? A cosmetologist weighs in on the effectiveness of collagen and amino acid injections for skincare. She explains that collagen's slow breakdown into amino acids provides a longer-lasting effect, while amino acid preparations offer rapid but shorter stimulation.

"Collagen breaks down slowly, providing prolonged amino acid delivery," she explains. "Amino acid treatments are sometimes better in cases of allergies or swelling."
