FACE OIL VS SERUM - WHAT SHOULD YOU BE USING?

Hi, babes! Emma here, and today we'll be talking about the key differences between face oils and serums. I'm sure many of you are already familiar with what each does, but I'm still here to provide a deeper understanding for those just starting out. 



Serums have become a staple in most beauty routines, from hyaluronic acid solutions that reduce the appearance of wrinkles to vitamin Cs that help to promote a more even skin tone. On the other hand, face oil is a more recent subcategory of skincare, yet it is growing in acceptance. Numerous skincare enthusiasts used to object to the idea of using oil to their faces in the past, and yet today jojoba and marula oils are popular choices for those seeking to soften their skin. 


Oil and Water

Both oil and water are essential for the skin’s proper function. The dermis holds collagen, elastin, and skin water to give the skin a plump and youthful appearance. The epidermis (skin barrier) contains important skin oils in the form of lipids, fatty acids, and ceramides. These oils form a barrier that prevents loss of the essential skin water. This mixture of  oils, also called sebum, also helps to lubricate the skin cells to give the skin a soft, smooth feel.


What Are Face Oils?




Face oils are liquid topicals that do not contain water. The exact composition of the face oil may vary, but as a rule, face oils are designed to mimic and supplement the skin’s natural sebum production. Because face oils tend to include larger molecules, their effects are typically limited to supporting the skin barrier. Linoleic acid and squalane are popular face oil ingredients as they mimic and support the skin barrier’s natural oil function.

The Benefits of Face Oils




Face oils are designed to deliver a unique balance of fatty acids and lipids to soothe and support the skin barrier. Barrier function is the skin’s number one function. The skin barrier prevents transepidermal water loss and protects the internal body from UV radiation, pollution, viruses, fungi, and bacteria. Damage to the skin barrier can lead to skin infections and a dull appearance, as well as irritation and dehydration.

The skin barrier naturally contains lipids, ceramides, and fatty acids. The production of these natural occlusives slows with age and is further worn away by environmental factors such as high wind and harsh cleansers. In addition, those with dry skin, eczema, and/or rosacea have genetic defects in their skin barrier function.

Really important note: Not everyone needs barrier repair. Those with oily skin tend to produce excess oil as is, and a face oil may further compound the problem of clogged pores and acne breakouts. 


What Are Serums?



A serum has a concentrated, lightweight formula that is typically applied after cleansing and toning and before moisturising. While face oils deliver their results physically by providing structural support, serums are classically designed to penetrate into the skin and regulate its internal functions.


The Benefits of Serums



Serums have a variety of benefits depending on the specific ingredients contained in the formula. 

Hydrating serums typically contain humectants, such as glycerin and hyaluronic acid, to draw water into the skin and increase skin hydration. Antioxidant serums, such as niacinamide and vitamin C, provide antioxidant support to skin DNA. Pigment-regulating serums, such as tranexamic acid and glycolic acid, help to normalise melanocyte activity and brighten the skin tone. 

There is significant variability in the feel and function of serums and they should be chosen based on skin concerns. They can be mixed and matched to create a personalised, individual skincare routine.


Which to Use (and When)



A face oil may be beneficial to those with dry and/or irritated skin, either seasonally or year-round. This includes those with eczema and rosacea. Since face oils are occlusive, they should be applied as the last step of the skincare routine after moisturiser. The goal is to lock in the good stuff and lock out the bad stuff. Those with acne or perioral dermatitis should exercise caution when adding a face oil to their routine, as face oils may potentially trigger a flare of these conditions. 

Serums can be a great addition to any routine. The right serum for you will depend on your specific skincare needs and desires. Since serums are lightweight, they are designed to be used before moisturisers. They can also be paired with a face oil, if needed, with the moisturiser sandwiched between the serum and the face oil. 


There you go babes, we've reached the end of this month's article! Did you enjoy it? Which do you use in your routine, serums or oils? Let me know in the comments and I'll see you all soon!

Love,

COLLAGEN: INGREDIENT DEEP DIVE

 Hi, babes!  Emma here with a little semi-deep dive into collagen. You've heard about it, you've seen supplements being advertised, and you have some inside you at the very moment, but how much do you actually know about it? Let's pick it apart today, shall we?  It is impossible to discuss anti-aging skincare without bringing up specific elements, one of which includes collagen. What's behind it though? The most significant structural protein in our skin, collagen is also responsible for providing us plump, youthful-looking skin, among other functions. But over time, our collagen degrades due to ageing and other external factors. We resort to whatever we can get our hands on the quickest in an effort to replace that lost collagen, be it collagen lotions, collagen-stimulating substances, collagen supplements - the list really is endless. Things might be rather overwhelming with all the various collagen skincare products on the market, which is why I'm here to guide y...

DARK UNDERARMS? NO PROBLEM

Image
Hi, babes! Emma here, and today I'll be sharing some tips for lightening your underarms. I'm sure that many of you, including me, have encountered this issue so here's some things that have worked for me. But first, a little breakdown on why this happens.  How do I brighten my underarms? was a question my sister and I asked our mum when we were in our teens. She told us that this was a question she was very well used to and we weren’t the first to ask or wonder about it. She said the issue humbled her greatly because it was a hard thing to treat, but she’d try.  So here are some tips and pearls of wisdom my mum, a dermatologist of over twenty years of experience, shared with us that I’ll in turn share with you.  Before we get into the how, I first need to tell you the why. Underarm skin is delicate. In terms of depth, it is analogous to eyelid skin. This means that it is very easy to irritate this skin, and unfortunately, irritation also produces additional pigmentation. ...

WHAT'S A MICROBIOME AND WHY IS IT IMPORTANT?

Hi, babes! Emma here, and today we'll be talking about something quite interesting. By that, I mean that we'll be learning out our skin's microbiome, the gut-skin relation, and of course nutricosmetics, which have been a strong trend these past few years when it comes to the beauty industry. Without further ado, let's dive right in. How frequently are we asked about our skin type when it comes to its qualities? The usual kinds, such as sensitive, normal, combination, oily, or blemish-prone, are therefore automatically used. Not that this terminology is inaccurate, but we can no longer make such straightforward inferences about our skin. Our skin is not as rigid or static as one might believe given that it is a complex organ. Understanding how our skin responds to the environment has an impact on how we take care of it. Skin Type vs Skin Condition We might comprehend that there are several "types" of skin, including normal, combination, dry, oily, and sensitive...
