The Jack Black Protein Booster Skin Serum is a peptide rich serum that includes: Matrixyl®3000, a multi-action peptide that helps reduce the appearance of wrinkles, SYN®-AKE, an advanced tripeptide that lessens wrinkle size, Renovage™, to increase moisture and brighten dark spots, Dynalift™, to firm the skin, as well as Green Tea and Organic Omega-3 Fatty Acids to soothe and brighten the skin. It’s always good to note that every skin type is different and that you should do a test patch before applying all over your face to see if this product is safe to use, as there have been cases of allergic reactions to this serum. All in all, we think this product is suitable for most skin types, but is definitely overpriced for such a small amount.
