“If you are using an exfoliating acid in the evening, such as a glycolic or even a retinol, you may need to cut down on the usage of this,” warns Helen. “Follow the rule ‘listen to your skin’– if your skin has been very dry throughout the day then hold off using anything exfoliating (even if its flaking and you want to scrub those flakes off)”. This is a rule that I definitely used to ignore. I thought that exfoliating would perk up my complexion and slough away the flaky patches of dry skin but in fact I was creating major disturbance to my skin barrier. When your skin barrier is compromised it’s not able to hold moisture as sufficiently, a real issue during winter. Now, during winter I reduce my exfoliants to fortnightly use and retinol to once a week and I get less flaking and less sensitivity. Instead, I focus on upping my vitamin C for brightening.
