In January, Olay introduced its Collagen Peptide 24 collection, which includes a serum, and eye cream, and the Olay Regenerist Collagen Peptide 24 Day Cream (£18), which is a great option to add to your regime if your skin is feeling a little dull and dry recently (so, everyone, right?). The hydrator combines palmitoyl pentapeptide-4 (also known as collagen peptide) as well as vitamin B3+, which together not only help improve the tone and texture of your skin — think less redness, smaller-looking pores, a touch more radiance — but also make your skin stronger and more resilient.
