How to apply concealer to different areas?

dark circles  For the dark and dull triangular area under the eyes, it is essential to first color-correct using salmon, peach, or apricot shades that are one tone lighter than your skin tone. After brightening the dull areas, apply a small amount of your usual base product to naturally blend the edges. Since the eye area lacks sebaceous glands and can dry out more easily than other parts of the body, it is best to use a moisturizing and creamy concealer. If the formula is thick, applying it while melting it with the warmth of your fingers or spraying a mist onto a base sponge can help control dryness.
 
Melasma & Pigmentation  You should select a shade that falls somewhere between the darkest of the unsightly blemishes and your usual skin tone to ensure an even complexion, even when finishing with cushion or foundation after applying concealer. Applying a lighter shade on top can actually make the spots stand out more, rather than providing coverage. Since melasma and blemishes often spread over large areas, you should dab a small amount two or three times, let it dry slightly, and then spread it thinly to achieve natural coverage without caking.
 
Nasolabial folds & nostrils  On a bare face, the areas with the most severe redness are the sides of the nostrils. In particular, these are the main culprits for foundation creasing most severely over time, highlighting wrinkles and making the skin look messy. In hot weather like this, sebum production increases and dead skin cells rise quickly, causing concealer to wear off easily, so meticulous layering is required. First, correct the uneven skin tone with yellow or green tones. Thoroughly correcting the redness alone allows for perfect coverage without darkening or creasing over time. Then, apply a very small amount of a sticky, thick concealer to a brush; finish by pressing firmly onto the skin rather than spreading it out.
