Collagen production is key when it comes to achieving a radiant, youthful-looking complexion, which is why Estée Lauder’s Resilience Multi-Effect Tri-Peptide Face and Neck Creme SPF 15 sets out to promote just that. Infused with the brand’s Tri-Peptide Complex, shown in in-vitro testing to significantly amplify collagen by 124% in just three days, it supports the skin in maintaining its natural firmness and tone, while defending its natural moisture barrier.
