Concealer is one of the beauty products I can never live without. When applied correctly, it can take years off your face, make that humongous red zit disappear and make you look flawless and below are a few rules I always abide to.
Rule # 1: Thou shall always choose the right product.
With the bazillion concealers and formulas out there nowadays, picking the right product can be tough so focus on what are you trying to cover.
For undereye circles, look for something with a high moisture content, like liquid and cream concealers. You can also use on with light-reflecting particles to brighten the undereye area.
As for blemishes or acne scars, go with a product with slightly heavier coverage and a matte finish. Pencil, stick and cream concealers are your best bet.
Rule # 2: Thou shall always pick the RIGHT SHADE for perfect application.
Again, this depends on what you are covering.
For undereye circles, use a concealer that is slightly lighter than your natural skintone to help brighten up the area. Be careful not to go too light, as it can make your circles appear worse. If you have serious darkness around the eyes, use a yellow or peachy corrector prior to your concealer to counteract the purple/blue undertones.
To cover up bags, choose a concealer that is one shade lighter.
As for zits, freckles, redness or other imperfections, use a concealer that matches with your skin tone completely.
Rule # 3: Thou shall always apply concealer AFTER foundation.
While certain people like to apply concealer prior to foundation, I always do it after. This way, you are less likely to overuse concealer and will look more natural. If you apply foundation after concealer, you also risk rubbing it off.
Rule # 4: Thou shall always PAT and not rub when applying concealer.
To camouflage undereye circles, first look into the mirror with your chin tilted slightly down. The darkest part (the area starting from the inner corner to the center of your undereye area) is where you should apply the concealer. Dip a concealer brush into the product and apply directly onto the darkest part. Blend either with a brush or index finger. Apply a light layer of powder to set the concealer or skip this step entirely if you have extremely dry skin. Click here for a step-by-step tutorial.
Contrary to what most people think, you should not apply concealer directly onto the bags. Instead, you apply it right under your bags. This way, the area will be highlighted hence making the bags look less obvious.
To hide a blemsh, use a brush and apply the concealer directly onto the zit itself. Make sure you blend the concealer into the surrounding area. Top with powder for maximum staying power.
For freckles and mole, apply the product directly onto the area with a brush or sponge. Pat with your index finger or a sponge to make sure the concealer is well blended.
