The king of quality sebum! This baby right here is responsible for ensuring the oil you produce in your skin is of good quality, watery thin consistency and not that of a cottage cheese. If your sebum is thick and gluggy, this leads to blockages which lead to breakouts. A skin without high quality omega 3 will also have a weakened barrier and a dehydrated skin.
This is without doubt, the most important step in your skincare routine.
