While recommendations from friends are always useful when it comes to knowing what beauty products to spend on, the consensus of millions of makeup lovers worldwide has to be up there, too.

Forget the new releases for now, today we’re shining the spotlight on trusted favourites that continue to top the best sellers lists years and even decades after their first release. The kind of products that have sold several units in the time it’s taken you to read this sentence.

Say hello to your new beauty to-try list.

1. Elizabeth Arden 8 Hour Cream, $26

You’d be hard pressed to find a beauty expert who didn’t have a tube of this lurking at the bottom of her handbag. Created in 1930, the original 8 hour cream continues to be the brand’s best seller – and one sells a casual every 30 seconds.

It’s a great multi-tasking product for all your skin woes from chapped lips and dry hands to rough heels.

2. YSL Touche Eclat, $63.

This luminizing pen is a miracle worker for hiding sleepless nights (voluntary or otherwise) adding instant light and lift to the face. Plus, the clicky end dispenser is rather addictive.

Seems being short of sleep is a worldwide problem, given one sells every 10 seconds somewhere in the world. Apply to the side of the nose, corners of the mouth, chin and over those eye bags.

3. Clinique Dramatically Different Moisturising Lotion, $49

A skincare staple for millions around the world, a bottle of this gets purchased every 4.87 seconds somewhere in the world. Yep, you know this must be something special.

A particular god-send for anyone with dry skin, it's moisturising without being oily and leaves skin feeling supple and smooth.

4. Maybelline Baby Lips Lip Balm, $3.95

Now this is mindblowing - seven tubes of Maybelline Baby Lips balm reportedly sell every 15 seconds. That's a lot of soothed lips out there.

Available in plenty of different colours and flavours, this is a favourite thanks to its SPF properties and comforting shea butter. A handbag/car/pocket essential. (Post continues after gallery.)

5. Napoleon Perdis Autopilot Pre-Foundation Skin Primer, $59

Say hello to one of the original primers. Launched in 2003, this has remained a top seller for the brand, with one selling every four minutes.

Once you've used it, it's clear to see why. The primer offers a smooth base for face makeup without the sticky feel of silicone and is the subject of founder Napoleon Perdis' catchphrase "Not to prime is a crime!" You heard the man.

6. Estee Lauder Double Wear Stay In Place Foundation, $50

If you're looking for high coverage long lasting foundation, it doesn't get much better than this. The long-wearing makeup range launched in 1997 and nearly 20 years later is still Australian's favourite foundation from the brand.

Internationally it's pretty beloved too, with a bottle reportedly selling every 12 seconds. We're sold.
