It can be difficult to add new products into your skincare routine if you have sensitive skin because the most simple of changes can make it angry. Sensitive skin occurs when the natural skin barrier has been compromised leaving symptoms such as redness, itchiness, flaking, and tightness. Keeping the skin moisturised with minimal irritation is key to maintaining a healthy functioning skin barrier.
If you have sensitive skin and want to experiment with acids, try using a small amount of lactic acid, The Ordinary's most gentle of all the acids. If you begin to have a reaction to this, immediately discontinue use.
