A thing we all know: Your skin changes a lot as you shimmy on into your 40s and 50s. And once you hit perimenopause, you'll start to notice even more changes.

Things like lines and wrinkles around your mouth, forehead and eyes, maybe some pigmentation, dryness and all that other fun stuff. This means that makeup starts to sitdifferentlyon our faces.

Meaning? A lot of what you've just 'always done' on the makeup front, might not work for your skin now. And that's okay! But the thing is, it's really quite hard to know what tweaks we can make to our makeup routine as we age.

The good news? It doesn't have to be complicated.

Watch: Mamamia's beauty contributor Teresa McNamara shares her thoughts on the popular Westman Atelier Vital Skincare Complexion Drops. Here are her honest thoughts.

In a recent episode of You Beauty's In Her Bag, host Lucy Neville spoke to celebrity makeup artist Amanda Ramsay, who is known for her expertise in makeup for over 40 skin.

And can confirm: the episode was positively bursting with juicy tips.

Ramsay has collaborated with names like Sophie Monk, Delta Goodrem, Julia Gillard and Miranda Kerr and has won a string of awards, including makeup blogger of the year and Australian makeup artists of the year finalist. So she knows her stuff. And she's on a mission to empower women and promote age positive beauty.

As Ramsay shared, "Over the last 21 years as a professional makeup artist, and growing older myself — I'm now 51 — I just noticed such a shift in women's skin, in my own skin, and things that I was using just weren't working for me or my clients anymore."

"So, it's a re-education, which I've loved sharing with other women. I love the power of makeup to put that spring in your step. I always say that yes, beauty is an inside job, one hundred per cent. But if you love what you see reflected in the mirror, and you get that little oh yeah moment, it can really transform how you feel about yourself into this next new chapter of life, which is the over 40 years."

With this in mind, we've pulled together a definitive list of Ramsay's top makeup products (and tips for applying them) for skin over 40.

Mii Cosmetics Forever Eye Colour Crayon, $49.

One of Ramsay's recommendations for easy, fuss-free eye makeup? UK-based brand Mii Cosmetics' range of crayons.

"It's like colouring in your eyelid — like anybody can do this, right? They are game-changing — it's easy eyeshadow in an instant that doesn't crease, crinkle or budge. And no matter how bad your eyesight is, you can do it."

"Colour in your eyelid and then take a soft fluffy blending brush and swish. It takes five seconds to do both eyes. Eyelids are very thin and what's great about this is it kind of 'primes' your eyelid, in that it evens the appearance of the skin and gives you instant colour and hold. So it's like a three-in-one product."

We love a multi-tasker!

"So just do like a windshield wiper motion through your socket and blend it up towards your brow bone."

Ramsay also said to add a bit of colour on your lower lash line, sharing, "It really creates balance, particularly for mature skins because we do feel like our eyes are slowly disappearing."

Using a small pencil-shaped brush with the same crayon, Ramsay said to swish it under that lower lash line for an added hint of balance and colour. Voila! Sounds way easier than powdered eyeshadow to be honest...

Rageism Beauty Award-Winning All Day Foundation, $68.

Next up, the all-important base. "Think about your complexion product as evening out skin tone not covering it up," said Ramsay.

The key to this? Choosing a lightweight liquid formula foundation. And according to Ramsay, the luminous and glowy Ragesium Award-Winning All Day Foundation is perfect for over 40s skin. In fact, as Ramsay shared, our very own Mia Freedman and Holly Wainwright are fans!

"It's an Australian-owned and made lady startup," she shared. "I'm pretty sure I put Holly and Mia on this some time ago."

"I really like mineral-based products, because they naturally bounce and reflect light. So they give you a lovely soft, diffused look to your skin. You want skin that looks like skin!"

Ere Perez Moringa All-Beauty Creme, $57.

If you're looking for a really light base to wear day-to-day, Ramsay said to mix an everyday formula like the Ragesim All Day Foundation above with a lightweight moisturiser for a lovely, fresh BB cream. Perfect if you just want that your-skin-but-better look without that 'heavy' feeling.

"I really like the Ere Perez Moringa All-Beauty Cream. It's beautiful. Mix that with your foundation for a lovely lightweight finish," she shared.

Noted!

Kylie's Professional Mineral Goddess Setting Powder, $58.

"The other foundation I like is the Kylie's Professional Mineral Goddess Loose Powder Foundation," said Ramsay.

If you're not a big fan of powder for mature skin, join the club — but according to Ramsay, this formula is pretty unique. "It is so high quality. It is perfect for all you girls that have a normal to oily skin," she shared. "This leaves the most radiant finish — almost like an airbrushed finish to the skin. It won't ever go cakey."

Sold. We'll take ten.

INIKA Organic Long Lash Mascara Black, $49.

When it comes to mascara, Ramsay has a holy grail find she said tops anything she's ever tried — which is a HUGE call for a makeup artist!

"It's INIKA Organic Long Lash — a black mascara. This one has been in my kit since the day it was born. And between then and now I've tested and tried gazillions," she shared.

"It's volumising and lengthening and it's sort of a tapered brush. So if you've got hooded eyes, you can get that bad boy right into the root of the lash and really load up the mascara. It's a really beautiful, easy, quick way to bring attention and definition to your eyes."
