20 Unexpected Culprits Provoking Your Atopic Dermatitis Flare-Ups
15. Essential Oils

Essential oils may smell soothing, but for those with atopic dermatitis, they can be a silent saboteur. Popular oils like lavender, tea tree, and citrus are highly concentrated and contain compounds that can irritate or even burn sensitive skin. Ironically, many are found in “natural” skincare labeled for sensitive users. Even if you don’t apply them directly to the skin, diffusion in the air can cause respiratory or dermal reactions. If you suspect oils are a trigger, eliminate them from your environment and look for fragrance-free alternatives. Just because it’s natural doesn’t mean it’s gentle—for eczema-prone skin, less is more.
16. Hormonal Shifts

Your skin might be more in tune with your hormones than you think. Menstrual cycles, pregnancy, menopause, or even starting/stopping birth control can cause flare-ups due to fluctuations in estrogen and progesterone. For women with atopic dermatitis, the week before menstruation often brings dry, inflamed patches. Hormonal changes affect skin barrier function, immune response, and inflammation—all key players in eczema. While you can't avoid these shifts, you can prepare for them: hydrate more, reduce irritant exposure, and be proactive with emollients. If your flare-ups seem cyclical, a hormonal pattern might be the hidden link.
