My skin barrier is typically quite vulnerable to cold and dry weather; I often have to top up my moisturizer throughout the day to quell that uncomfortable feeling of tightness and dehydration. This peptide one, however, leaves my skin hydrated for hours on end without feeling oily. Because of its fast-absorbing nature, I often forget that I’m wearing it; at the same time, my skin stays bouncy, plump and smooth all day — no reapplication required.
