We know by now that oily skin isn't necessarily the enemy, although sometimes, it can sure feel like it. A perfectly matte complexion might not be something to aspire to, but there is satisfaction to be found in balance: after all, your skin needs oil, but an excess of the greasy stuff is less than appealing.
But keeping your face on the right side of shiny? That is totally possible. Understanding your oily skin is the key to managing (not eliminating) it, and once harmony is restored, you'll have a happy, healthy complexion that looks glowy, never greasy.
To finally sort fact from fiction, we grilled the experts for some sage advice on keeping oily skin as its healthiest, most resilient state. Here, see everything you need to know, including the top ten reasons your skin feels oilier than usual, and the best treatments to try now...
What causes oily skin?
'Our skin's oil is called sebum. It's produced by the sebaceous gland in the hair follicle', explains Andrea Pfeffer, founder of Pfeffer Sal. 'Per cm2, the skin on our face has more hair follicles than on the rest of our body, which is why we experience oiliness mainly on the face.'Pfeffer explains: 'The main function of sebum is to lubricate the skin, limit the growth of bacteria and prevent dryness and dehydration.' The amount of sebum we produce is determined by a host of internal and external factors, from the cleanser you're using (more on that later), to the weather, your genetics and even your hormones.
8 Ways To Manage Oily Skin
1. Master Your Daily Cleansing Routine
When you have oily skin, the urge to wash your face at every available opportunity can be strong. But according to facialist Joanne Evans, your frequent face-washing habit may actually be making things worse. 'It seems logical that removing the skin's oil would be the best way to clear oily skin, but over-cleansing actually activates further oil production', she says. Simply speaking, when you cleanse so much you remove the skin's natural and necessary sebum reserves, it's going to rectify things by producing more. 'Sebum is vital for skin function and over-cleansing the skin will actually lead to more problems than it solves including increasing oil production', agrees Pfeffer Clearly, the cleanser you choose is crucial but between milks and gels, foams and water, it can be near-impossible to decide which one is best for an oil- prone complexion. Pfeffer advises using a cream or milky cleanser, as these will dissolve dirt and debris without disturbing the barrier function and natural moisture levels of the skin. 'You can also go for a cleanser with BHAs in it to really assist in dissolving excess oil', she suggests. Furthermore, don't be fooled by that super-strength, alcohol-steeped cleanser that claims to be formulated for oily skin. Which leads us on to...
2. Be Wary Of Products Formulated For Oily Skin
Believe it or not, products specially formulated for minimising oiliness often exacerbate the situation, as so many contain harsh ingredients that sweep away every last drop of sebum from the skin (and we all know what that means). According to Pfeffer, the main culprits are products containing alcohols, astringents and sulphates, so check the back of your bottle before making a purchase. 'This means many old-school toners and foaming cleansers are off the table and for good reason!', she says. 'Whilst they'll have a satisfying short-term effect of removing the excess oil on the surface of the skin, over time the lack of oil in your skin will trigger excess oil production to try and make up for the oil that's stripped away.'
Furthermore, these harsh products can interfere with your acid mantle: the skin's protective barrier. 'A disrupted skin barrier can lead to sensitivity, breakouts, inflammation and dehydration', warns Pfeffer. So, the verdict is clear: if any products in your routine are making your skin feel dry and tight, give them the boot.
3. Don't Ditch The Moisturiser
A common misconception is that skin can either be oily or dehydrated but in fact, it can be both. This means there's little sense in ditching the hydrating products which are, in fact, essential in every skin routine no matter your skin type. Hydrating products are necessary to maintain moisture levels as we know, if your skin is lacking in hydration, oil production can go into overdrive to compensate.
But before you reach for the first face cream within your grasp, consider that your choice of product is an important one. If you're worried about blackheads and blemishes as well as that dreaded shine, it's best to avoid those that are super-creamy, heavy and occlusive. 'Your skin probably won't appreciate thick heavy moisturisers, so avoid any creams with rich plant butters as these are likely to be too rich and lead to congestion', advises Pfeffer.
4. Get To Grips With Salicylic
Acids are an important step in any regime, but leave-on BHAs like salicylic acid play an especially important role in controlling over-zealous oil production, which in turn minimises the development of blackheads and blemishes. 'Salicylic acid is a beta-hydroxy acid which is lipophilic, meaning it is attracted to and helps to break down excess oil', says Pfeffer. 'As an added bonus, it's anti- inflammatory and can penetrate pores to scoop out any debris, making it a great ingredient for targeting the congestion that often comes hand in hand with oiliness.'
The best way to incorporate salicylic acid into your routine is with a twice- daily exfoliant, swiped over skin after cleansing. Just don't make the mistake of rinsing it off: it'll be nowhere near as effective at sweeping away any greasiness. If you're using a salicylic acid cleanser instead, leave it on for two minutes before washing (a great opportunity for a little facial massage).
5. Address Your Diet
According to Evans, the root of your oily skin issues could actually lie in your gut. 'If you suffer from oily skin, avoid sugar and dairy, as they feed and increase oil production', she explains.'What's more, a diet deficient in zinc, magnesium, vitamin B and omega 3 may contribute to oil production.'
Pfeffer agrees, recommending in particular that we eat more zinc-rich foods. 'Zinc helps to regulate the oil-producing glands, so they behave better! Great sources include shellfish, legumes and nuts.'
And of course, it's crucial to consider your intake of sugar. 'A high sugar intake can also increase oil production, as insulin creates the hormone IGF-1 which can increase the production of sebum', explains Pfeffer.
6. Consider Your Hormones
Internal hormone fluctuations are one of the main causes of imbalanced oil levels, according to Pfeffer. 'Specific hormones called androgens put sebum production into overdrive, resulting in more oily skin, and sometimes breakouts as a result.' Androgens can be released in times of stress, or through hormonal changes such as the menstrual cycle, contraception, PCOS, puberty, pregnancy and postnatal, and the menopause. In particular, multiple studies have indicated a positive correlation between stress levels and sebum production in people with acne-prone skin. Of course, these aren't exactly situations within your control, but you can attempt to maintain balance by paying attention to your sleep habits and stress levels.
7. Indulge In A Clay Mask
Today's beauty shelves might be piled high with increasingly innovative formulas, but sometimes, the oldest treatments remain the best. Pfeffer is keen to remind us of the benefits of a good old clay mask: 'They're fantastic allies when targeting oiliness as they act like sponges, absorbing excess oil', she explains. Thankfully, you don't need to spend a fortune on a mud mask, either: simply look for one containing French green or bentonite clay, as these are generally the most absorbent. Kaolin clay is a great all-rounder, too.
8. Choose Your Foundation Wisely
When you've got oily skin, don't restrict yourself to long-wear liquid foundations. Mineral powders come with so many benefits: not only are they largely non-comedogenic (meaning they won't clog your pores), they're unrivalled in the oil-absorbing department, and can easily be layered up as the day goes on. But if you're loyal to a liquid, that's fine too just invest in a great setting powder to seal the deal. 'The Laura Mercier Translucent Loose Setting Powder is my holy grail powder for oily complexions as it keeps skin shine-free for hours on end', says make-up artist Gabriella Floyd, who has a pretty clever oil-eliminating technique of her own. 'My top tip is to apply it using a damp Beautyblender', she says. 'This allows you to really press the powder into your skin so it doesn't budge as the day goes on.'
If you're on the go, it's fine to use a pressed powder to stop your foundation from slipping off, as long as it's super-light. 'To prevent shine throughout the day, pick up something really finely milled like Charlotte Tilbury's Airbrush Flawless Finish', adds Floyd. 'You can keep topping it up and it never, ever gets cake-y, which is why it's a go-to powder in my kit - for my clients and myself.'
