You're not alone and there are many people who suffer from this condition called Keratosis Pilaris. Keratosis Pilaris  results from dry, impacted skin blocking the follicles, causing inflammation and tends to  be more common in winter due to dry air, cold wind, heated rooms, hotter showers/baths etc exacerbating skin dehydration. AHAVA have a skin regime to help alleviate the condition: AHAVA’s Purifying Mud soap (daily cleanse), Liquid Salt 2-3 times per week and a good body moisturiser e.g. Dermud Body Milk or Mineral Body Lotion.
