Well … oil-based cleansers are good to remove makeup, rosehip oil is used on the face and neck to give better slip for massage tools, or simply applied to the a very dehydrated face to give a more hydrated appearance (note this statement).
However, and it can vary from person to person, chemical formulation and dermatologist statements regarding facial oils prove that this step is not as crucial and beneficial to the skin as people have been led to believe via marketing.
Whether you have oily or dry skin, topical oils alone cannot give you a level of moisture that’s required for healthy skin. If you apply it on oily skin – you’re creating even more problems right there, or if you apply it on dry skin – it’ll only give the appearance of hydration, not the actual skincare benefits you’re looking for.
What does the oil do, then?
“Most oils that are applied to the skin end up forming more of a protective barrier on its surface, rather than actually penetrating the skin,” Dr. Hollmig states. So, although oils are moisturizing and may indirectly increase the amount of hydration in the skin, they are not technically hydrating (SELF Magazine).
The crucial factor here is the size of the fatty acid molecules that make up the oil. If they’re too big to get through the skin barrier, they sit on top and act as occlusives. If they’re small enough to get through, they may be able to penetrate to deeper layers and strengthen the stratum corneum. For instance, research suggests that jojoba oil and argan oil can actually help repair the skin barrier.
Plus, some oils come with other benefits, such as antioxidants or anti-inflammatory properties, that might make them beneficial for certain skin concerns. Whether or not an oil is the best choice for that issue is another question (TODAY).
Save oil for the final step of your skin-care routine. If you apply an oil first, any moisturizer that follows won’t be able to fully penetrate the oil barrier; it’s like applying lotion over a wet suit. Remember, oils are only the gatekeepers, not producers, of hydration, so load up on humectants first, and then pile on the oil afterward to keep moisture from escaping (The Cut).
Oils CAN clog your pores! But not all oils. Mineral oil is a chronic offender, as well as olive oil, oil du jour, and coconut, easily clog pores, too. So which oils don’t cause breakouts? The answer depends on you. Though there are oils that are less likely to irritate, like marula and argan, your unique genetic skin makeup will determine your oil tolerance. It’s annoying to admit, but trial and error is your best bet at determining what will work for you.
If you want to incorporate using a facial oil, consider your skin type and needs, conduct sufficient research, seek advice from a dermatologist and definitely do a test-run to see if your skin can handle a specific formulation of your chosen oil.
