Balance. This is when your skin is poised at its optimal texture, tone, and moisture level. No excessively pigmented or excessively light areas. It's important to always remember that none of us are perfect and so there will always be something a little bit more or less out of balance :: and the trick is to keep the "out of balance" at a minimal. Start with gentle cleansing, a properly balanced pH toner, and a protective moisturizer. By all means, avoid harsh skincare products and techniques. As always, a best practice is listen to, observe and feel your skin. Treat it with gentle care. No hot or cold water, but rather nice, warm water. No harsh scrubs or acid masks. Your skin will tell you what it likes and what it needs.
