Luckily, you have us.

We're going to bring together a few of the biggest and best skincare brands that are kicking around, and tell you three of the best products you can buy from each of them.

Let's go.

SkinCeuticals.

SkinCeuticals CE Ferulic Serum, $228.

Every girl and her pet rock has heard of CE Ferulic Serum. Dermatologists love it. Beauty editors froth over it. And for good reason - it does somevery good thingsto your skin.

Packed with antioxidants like vitamins C, E, and ferulic acid, this fancy hot dog water (just give it a sniff) protects the skin from free radicals for brighter, more even skin. It's expensive as hell, but the results speak for themselves.

SkinCeuticals Hyaluronic Acid Intensifier, $183.

Have you tried this? No? Ooft, it's good. Expensive, but good.Especiallyif you're prone to dry skin. It contains a high concentration of pure hyaluronic acid to help lock in moisture, while ingredients like licorice root and purple rice (yum) work to smooth and plump the skin.

A couple of drops go a long way - it's the perfect addition to any skincare routine.

SkinCeuticals Phyto Corrective Gel Calming Serum, $100.

Combing hyaluronic acid with calming ingredients like cucumber, thyme and eucalyptus, this soothing gel/serum helps to nix visible redness, while making the skin a million times softer and brighter. If you have rosacea or sensitive skin, this might be one for you.

The Ordinary.

The Ordinary Niacinamide 10% + Zinc 1%, $10.

When it comes to the best overall product from The Ordinary, this is one of the top-selling skincare products from the cult brand. And with its affordable price and the long list of benefits, it's pretty obvious why.

Formulated with a high concentration (10 per cent) of niacinamide (vitamin B3), and one per cent zinc, this serum works to reduce blemishes and congestion, improve skin texture and encourage collagen production. Phew!

If you suffer from dry skin or breakouts (or both), this is your guy.

The Ordinary Lactic Acid 10% + HA 2%, $12.70.

If there's one thing The Ordinary does well, it's exfoliants. They have tons of 'em. Lactic Acid 10% + HA 2% is one of our faves of the bunch because it's a gentle formula that's perfect for more sensitive skin types, or those who've never dabbled in chemical exfoliants before.

The best part? It contains added hyaluronic acid, so it moisturises the skin while doing all the heavy lifting with dead skin cells and such.

The Ordinary Squalane Cleanser, $34.90.

Another stellar product you can't go past is the Squalene Cleanser. While the brand currently offers approximately 3872 serums, this is the only cleanser - and gosh, it's a good one.

Great for all skin types, it has a unique oil/balm texture that's perfect for melting down makeup and all the day's junk. Bonus: It won't leave your skin feeling tight, dry, and gross. Cool!

La Roche-Posay.

La Roche-Posay Rosaliac AR Intense Serum, $41.95.

Another goodie for those who struggle with rosacea or sensitised skin, Rosaliac AR Intense Serum is an absolute banger when it comes to reducing and preventing redness.

It's like a serum, but with a thicker, gel-like texture. Formulating with skin-soothing ingredients, it also contains something called ambophenol - which sounds like total gibberish, but it actually helps constrict blood vessels to visibly reduce redness. How cool.

La Roche-Posay Toleriane Dermo-Cleanser, $27.95.

If you have skin on your face, you're going to love this cleanser. It has the most beautiful lightweight, milky texture and can be used all over the face and eyes to cleanse the skin without irritation. It's the perfect go-to everyday kinda cleanser.

La Roche-Posay Cicaplast Baume B5, $17.95.

This multi-tasking balm is good for EVERYTHING. Whether you've just burnt your skin barrier off, you're experiencing some irritation, rashes or want to give your skin a boost of hydration, it's a serious all-rounder.

Just to give you an idea of how good it is - one tube is sold every 15 seconds in Europe. NBD.

Murad.

Murad Rapid Age Spot Correcting Serum, $115.

If you've been blessed with dark spots, this is one Murad product you should add to your armoury.

Packed full of do-good actives, it tackles the appearance of pigmentation and uneven skin texture, giving the skin a more even and radiant tone. 11/10 would recommend.

Murad Resurgence Retinol Youth Renewal Serum, $138.

Another goodie that's part of the Murad fam is this gentle retinol serum. Perfect for beginners, it uses hyaluronic acid to minimise dryness and the 'retinol scaries', while still being powerful enough to make a difference to your skin.

You'll notice a more even skin tone, less prominent lines and boosted radiance.

InvisiScar Resurfacing Treatment, $56.
