There are many products available that will cover up a tattoo; however, if you are in a pinch, you can use everyday cosmetics to conceal tattoos. All you need are a few items from your make-up bag for covering your ink in a hurry. If you have this most personal of artwork on your body in any visible place, it would be a good idea to carry these items with you at all times in case you need them.
Apply concealer. If you happen to have two shades, use them both. Put on the lightest shade first, applying it as you would when covering up the dark circles underneath your eyes. Blend it well into the surrounding area. Repeat this using the darker concealer if you have some.
Apply powder on the tattoos. Although a brush will work, a pad is much better. Press the pad firmly into the compact before dabbing evenly and gently across the concealer.
Apply foundation. Once again, if you have a darker shade and a lighter one, use both. Put it on as you would on your face, using a light touch, applying the lighter shade first. You can always apply more but, if you put too much on, you'll have to remove it all and start over with the concealer. Instead of using makeup sponges, as you would when applying theatrical makeup, use your fingertips to blend it in well. This gives you more control and better coverage. Do the same with the darker shade of foundation if you have it before repeating Step 2 and applying powder.
Apply eyeshadow or blush. Choose a shade that is close to your skin tone. Use a small cosmetic brush to sweep it over the tattoos, dabbing in areas that seem harder to cover. Put it in light coats, building the coverage and color as needed. Make sure to blend it into the surrounding areas as you go. Repeat step 2 to seal it all in.
