During cold weather, the skin loses moisture, leading to dryness, barrier damage, and temporary darkening. To treat this, look for over-the-counter ointments containing thick emollients like petroleum jelly, glycerin, or hyaluronic acid to lock in moisture. For rough skin, creams containing urea or lactic acid will gently exfoliate and soften. To address the darkening, ingredients like niacinamide or vitamin C can help even out skin tone. Apply these creams immediately after washing your hands while they are still damp, and wear gloves outdoors. If your hands crack, bleed, or do not improve, please consult a healthcare professional for a personalized evaluation.
