Night-time is when the body regenerates – just as your internal organs go through repair processes (while you’re dreaming away), your skin (aka your biggest organ) needs time to regenerate too. If you have skincare (like SPF), makeup or dirt sitting on your skin overnight, this stops the process, blocks pores and can lead to spots, excess oil and sometimes irritation.
Not everyone needs to cleanse in the morning. Some more sensitive or dry skin types might not need it, but that evening cleanse is a must for all skin types. If you want to cleanse, you can rise with cold or lukewarm water.
