- Look after your lipids: Pick up a slightly more emollient moisturizer, like Aveeno Creamy Moisturizing Oil ($9). Skin gets drier in cooler weather, and one of the best ways to keep it from having issues is to keep your lipid barrier well protected.
- Stop before you slough: Use acids and scrubs a little less frequently. When you exfoliate, skin is more sensitive, and cold air or harsh weather conditions can often exacerbate skin issues.
- Acid trip: Get a serum with hyaluronic acid, like Trish McEvoy Beauty Booster ($128). Hyaluronic is a humectant, which means that it helps keep skin hydrated. And if you happen to have oily skin, a serum's gel-like consistency won't be too greasy for you.
- Noninflamed dame: Allergies, rosacea, and eczema tend to act up during seasonal transitions, so keep your skin soothed with calendula extract or another anti-inflammatory.
- Easy does it: Use a gentle cleanser that's fragrance-free and nondrying, like Kiehl's Gentle Foaming Facial Cleanser ($20). It will keep your skin's reactivity low and irritation at bay.
