Dry skin doesn’t contain enough oil, so it lacks a sheen and plumpness, pores appear smaller, it can look red, sore and get aggravated easily and be itchy and flaky in places. It could feel tight and possibly be difficult to rub moisture products into the skin.
Dehydrated skin doesn’t contain enough water, looks grey and washed out, has a feeling of tightness and dryness – although it can still appear oily and spotty and have large or small pores. The skin is thirsty and it quickly absorbs the water in moisturizers and makeup, causing patchiness or shine.
