To use this concealer, first clean your face. If you're dealing with sunburn or skin irritation, apply Mellow Yellow directly to the affected area to neutralize the redness. For hiding bruises, birthmarks, or capillaries, pair it with the MY Series. Apply it as a facial corrector before your base makeup for better coverage. You can also blend it with other neutralizers for a custom - look. Make sure to store it in a cool, dry place. Don't let it get too hot or cold as it may affect the texture. With proper care, this 8.5gm./0.3oz concealer can last you through 25 - 80 applications.
