While <a href="/howto/guide/how-much-fat-should-i-eat-each-day" target="_blank" rel="noopener"><span class="s1">fats</span></a> are often shunned because of their high calorie content (9kcal per gram compared to 4kcal in carbohydrate and protein) they are in fact one of the most important dietary elements in skin health.</p>
<p class="p1">Read on to discover which fats you should be enjoying in your diet and why.</p>
<p class="p1"><strong>Discover <a href="/howto/guide/what-eat-glowing-skin" target="_blank" rel="noopener">what foods are good for your skin</a>, how to <a href="/howto/guide/eat-your-way-fabulous-skin" target="_blank" rel="noopener">eat your way to fabulous skin</a> and find out <a href="/howto/guide/collagen" target="_blank" rel="noopener">if collagen supplements really work</a>. </strong></p>
<h2 class="p1">What is skin made up of ?</h2>
<p class="p1">Your <a href="https://www.ncbi.nlm.nih.gov/books/NBK470464/" target="_blank" rel="noopener"><span class="s1">skin</span></a> is your largest organ and is made up of two main layers – the <a href="https://lpi.oregonstate.edu/mic/health-disease/skin-health/essential-fatty-acids#:~:text=Conclusion-,Omega%2D6%20(n%2D6)%20and%20omega%2D3,to%20skin%20function%20and%20appearance" target="_blank" rel="noopener"><span class="s1">epidermis and dermis</span></a>. The outer epidermis provides the main barrier, preventing water loss and protecting from pathogens while the inner dermal layer ensures strength and elasticity and supplies nutritional support.</p>
<p class="p1">The skin you show to the world is created deep in the dermis. These skin cells are pushed up, layer by layer, until they reach the surface. This process takes around four weeks, which means changes in your diet, for better or worse, may take a little while to show.</p>
<p class="p1">Each of your skin cells is surrounded by <a href="https://pubmed.ncbi.nlm.nih.gov/22534876/" target="_blank" rel="noopener"><span class="s1">two layers of fat</span></a> that make up the skin cell wall – this is known as the <i>phospholipid bilayer.</i> This layer incorporates dietary fats and is crucial for giving the appearance of plump, healthy skin and for playing the functional role needed.</p>
<p class="p1">Although it may come as a surprise, your skin is a <a href="https://lpi.oregonstate.edu/mic/health-disease/skin-health/essential-fatty-acids#" target="_blank" rel="noopener"><span class="s1">metabolically active organ</span></a> and this means it can make and modify saturated and mono-unsaturated fats as well as cholesterol. However, there are other fats, known as essential fats, that the skin can’t make and you need to obtain these from your diet.</p>
<h2 class="p1">Which are the essential fats for the skin?</h2>
<p class="p1">Your skin is unable to make certain types of fats these include:</p>
<h3 class="p1"><b>Omega-6 fatty acids</b></h3>
<p class="p1">Linoleic acid is an omega-6 poly-unsaturated fatty acid found in plants including seeds and their oils, it is one of the <a href="https://lpi.oregonstate.edu/mic/health-disease/skin-health/essential-fatty-acids#" target="_blank" rel="noopener"><span class="s1">most abundant fats </span></a>in the epidermis and plays a crucial role in forming a protective barrier. The second most abundant fat in the epidermis is <a href="http://www.ncbi.nlm.nih.gov/pubmed/3097227" target="_blank" rel="noopener"><span class="s1">arachidonic acid</span></a> – also an omega-6 fatty acid you can get it from <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6052655/#:~:text=Arachidonic%20acid%20is%20obtained%20from%20food%20such%20as%20poultry%2C%20animal,for%20phospholipid%20synthesis%20and%20their" target="_blank" rel="noopener"><span class="s1">poultry, fish, seafood and eggs</span></a> or it is converted in the liver from plant sources of linoleic acid. Arachidonic acid forms the structural walls of the skin cells in the epidermis.</p>
<h3 class="p1"><b>Omega-3 fatty acids</b></h3>
<p class="p1">These are present in only small amounts in<b> </b>the epidermis, they play a more important role in <a href="https://lpi.oregonstate.edu/mic/health-disease/skin-health/essential-fatty-acids#" target="_blank" rel="noopener"><span class="s1">protecting the collagen in the dermis</span></a> and as a result may have an anti-aging effect.  They also have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/33613558/" target="_blank" rel="noopener"><span class="s1">anti-inflammatory properties</span></a> which means they may help reduce irritated skin caused by conditions like psoriasis or atopic dermatitis.</p>
<h2 class="p1"><b>How can I get the balance right?</b></h2>
<p class="p1">One possible cause for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8504498/" target="_blank" rel="noopener"><span class="s1">inflammatory skin disorders</span></a> is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7037798/" target="_blank" rel="noopener"><span class="s1">increase in omega-6 fats</span></a> in our diets. A typical Western diet contains far more omega-6 fats because they are found in most of the vegetable and seed oils that we commonly use in cooking, as well as in processed foods, whereas omega-3 fats, have far fewer food sources.</p>
<p class="p1">Determining what constitutes the ideal ratio between omega-3 and -6 has proven controversial and more recent <a href="https://pubmed.ncbi.nlm.nih.gov/31979308/" target="_blank" rel="noopener"><span class="s1">studies</span></a> support the need for a balanced combination of both of these essential fats to help manage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7037798/" target="_blank" rel="noopener"><span class="s1">inflammatory skin conditions</span></a>.</p>

<h2>Which foods should I eat for skin-friendly fats?</h2>
<p class="p1"><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8504498/" target="_blank" rel="noopener"><span class="s1">Omega-6 fats</span></a> are found in sunflower, sesame and pumpkin seeds as well as pine nuts, peanuts and soybean oil.</p>
<p class="p1">Omega-3 fatty acids are found in:</p>
<ul>
<li class="p1"><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8504498" target="_blank" rel="noopener"><span class="s1">Oily fish</span></a> like salmon, mackerel, sardines, cod, anchovies, trout and halibut, these are rich sources of omega-3 fats, while shellfish such as mussels, oysters, squid and crab are also useful sources.</li>
<li class="p1">Nut and seeds such as walnuts, linseeds, pumpkin, chia and hemp are good<b> </b>vegetarian sources of omega-3, albeit in a slightly less active form to that found in fish.</li>
</ul>

<h2 class="p1">Which other foods and nutrients may be helpful?</h2>
<p class="p1">In addition to dietary fats, certain fat-soluble compounds including carotenoids and vitamins like A and E play an important role in maintaining skin health. Here is where you can find them:</p>
<ul>
<li class="p1">Avocado – rich in mono-unsaturated fats as well as protective <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6719967/" target="_blank" rel="noopener"><span class="s1">fat-soluble carotenoids</span></a>, avocado is one of the few fruits that provides significant levels of both skin-friendly vitamins C and E. A <a href="https://pubmed.ncbi.nlm.nih.gov/35037373/" target="_blank" rel="noopener"><span class="s1">2022 study</span></a> suggested one avocado daily over an eight week period may enhance skin elasticity and firmness.</li>
<li class="p1">Fish, soy, egg yolk, almonds, Swiss chard, seeds and sweet potatoes are all valuable sources of <a href="https://pubmed.ncbi.nlm.nih.gov/31638351/" target="_blank" rel="noopener"><span class="s1">biotin</span></a>, one of the B group of vitamins, biotin is key for the metabolism of fat in the skin which is important for skin hydration and appearance.</li>
<li class="p1"><a href="https://ods.od.nih.gov/factsheets/VitaminA-HealthProfessional/#:~:text=Sources%20of%20Vitamin%20A,-Food&amp;text=Concentrations%20of%20preformed%20vitamin%20A,1%2C5%2C14%5D" target="_blank" rel="noopener"><span class="s1">Liver, fish, eggs and dairy products</span></a> are some of the best food sources of preformed vitamin A. Although leafy greens and orange and yellow fruit and vegetables are where most of us get pro-vitamin A, the form that needs to be converted in the body. This fat-soluble vitamin plays an important <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/35889909/" target="_blank" rel="noopener"><span class="s1">regulatory role</span></a> in the skin and appears to have an <a href="https://www.mdpi.com/2079-9284/10/5/144#:~:text=The%20present%20study%20suggested%20that,of%20this%20%E2%80%9CIn%26Out%E2%80%9D%20strategy" target="_blank" rel="noopener"><span class="s1">anti-aging effect</span></a>.</li>
