1/ What is an Oil

An oil is not a moisturiser. It has never been able, nor will ever be able to moisturise your skin. I know, stop the presses. An oil, unlike a moisturiser, acts as an occlusive, and sometimes as an emollient.  To understand this concept, we must first understand what these terms mean. Using an emollient on your skin only acts to soften the surface as it will not be absorbed deeper than the epidermis. They smooth out flaky skin cells and work to make the skin appear smoother. On the other hand, an occlusive coats the skin and forms a physical barrier that prevents the loss of water. Together, they add barrier protection, silkiness, and superficial hydration. For optimum results, combine oil with a serum/moisturiser that contains ingredients such as glycerin and hyaluronic acid. Together, these will maximise the delivery of water deep into the skin while the oil will act as a sealant that keeps moisture in. Using a moisturiser alone will allow water to leech out of your skin until the next time you apply one. Adding oil to your routine will prevent this, and is especially important during the winter months when temperatures drop, and your skin is under increased pressure. Using an oil over your moisturiser will protect against harsh conditions and help prevent dehydration.

2/ How to Use a Face Oil

Oil should be the final step in your skincare routine. Make the rookie mistake of applying one before your moisturiser and run the risk of missing out on all the skincare benefits it would otherwise supply. Remember, oils act as a barrier on the skin; they work to prevent water from escaping and conversely, will make it difficult, if not impossible, for a moisturiser to penetrate the skin. For ultimate hydration, humectants should be applied to the surface first followed by oil.

3/ When to Use an Oil

An oil fan, I use one year-round day and night and credit it for my dreamy soft skin and dewy glow. While this may not be for everyone, oil definitely has its place in your bathroom. Packed with essential nutrients, fatty acids and much more, it will give skin an instant softness and smoothness that is incomparable. Suitable for use on all skin types, even oily skin, there is an oil for everyone. Yes, they have the potential to clog pores, especially mineral oils, be mindful when choosing an oil for you. When selecting an oil take into account your skin type, concerns and what you are looking to achieve. Use sparingly, every other day remembering that trial and error is your best bet at determining what will work for you.
