Here are the expert tips to streak-free self-tanning.

We’ve all made self-tanning mistakes - including those telltale signs such as orange palms, blotchy elbows, knees, and ankles or a streaky-looking finish. But once you learn the right technique, and find the right product to suit your skin, you will be sporting a faux-glow that looks nothing short of perfect. Editor Trudi Brewer shares her best tips on TV3’s The Cafè.

How does self-tan work

The active ingredient in self-tan is dihydroxyacetone (DHA). A plant extract from sugar cane or beets, which reacts with the amino acids in the top, dead layer of your skin to temporarily turn it brown.

How to prep the skin for self-tan

Dry skin is a barrier to an even self-tan result. Make sure you exfoliate and moisturise well prior to tanning so that lotions or mousse or tanning spray can absorb into the skin. Shave the legs (another great way to exfoliate your skin), and if you wax make sure this is done 24 hours before to allow the hair pores to close. Remember, post-tanning waxing and shaving speeds up the fading process.

How to apply tanner with a mitt

A tanning mitt is the only way to get an even application. Blotches generally appear because you have missed spots or applied the tanner unevenly. When applying, make sure the skin is clean and dry, without fragrance. Massage the tanner into the skin in small, circular movements starting at your legs and then move up the body, finishing with the feet backs of hands. Don’t rub up and down as this can create an uneven finish. Most importantly, a tanning mitt protects your palms from going orange.

Apply a light layer of self-tan to the face

Cleanse the skin and then apply tan over the top of a lightweight moisturiser. Your face is often darker than the rest of the body, so aim for a subtle-looking bronze glow, and then re-apply every few days.

How to fix up any mistakes

If you see any streaks on your body, buff your skin with a grainy scrub on a body sponge. Another trick is to apply a little nail polish remover to a cotton ball and rub it over the streaks, moisturise and then reapply.

How to make your tan last

The top layer of skin sheds naturally, every month, and with it goes your bronze glow. Extend the life of your selt-tan using gradual tanner. Once your tan starts to fade, exfoliate and repeat the tan application again
