Peptides are amino acids that your body already naturally produces. Your skin needs these amino acids to build certain proteins, like elastin and collagen. Even though our bodies produce peptides regularly, as we age, our body produces less and less, leading to fine lines and wrinkles, loss of firmness, and less suppleness. If you want to preserve your skin’s resilience, strength, and texture, a peptide serum can help. Learn more about peptides for skincare when you shop Senté.
