Your Lips: Everything You Didn't Know

Your Lips: Everything You Didn't Know

Lips allow us to produce sounds, express emotions, and kiss the ones that we love. In fact, kissing is how we share key DNA information with a potential love interest in order to see if we are a match. Why? Well, because our lips have thinner skin, and numerous nerve endings, they play an important role for evolutionary and personal reasons. That being said, since they’re so unique when compared to the rest of the skin on our bodies our lips need a little extra love and care to keep them at their prime.

There isn’t another part of our body that shares the same skin structure as our lips. Though all skin is composed of three layers, they’re completely different on our lips. How? Well let’s start with a quick skin lesson.

The Dermis: This is your deepest layer of your skin which is where sweat glands and hair follicles are located.

The Epidermis: This is your skin’s middle layer which is responsible for producing new cells. It also produces melanocytes, which are the cells responsible for producing melanin (what is responsible for giving our skin its colour, while also protecting us from UV rays).

The Stratum Corneum: This layer is a thin, protective layer that is essentially composed of dead skin cells.

By the way, theres a glossary at the bottom and all the words that are italicized can be found there for all our brains to soak up.

Now back to our original conversation. You’ve probably noticed that your lips look different from the rest of our skin because they’re a different colour or shade.

The thin stratum corneum (which is thinner on our lips than anywhere else on our body) and the lack of melanin in the lips, allows underlying red blood-vessels and capillaries to be more apparent. This my friends, is why our lips are a different colour than the rest of our skin.

The lack of melanin and thinner skin also makes your lips more susceptible to sunspots and skin cancer. All of our lips also have no sweat glands, hair follicles or sebaceous glands. All of these are critical in protecting and moisturizing the skin all over our body. So, as you can imagine, your lips are more prone to dryness and chapping. Quick fact, the only natural source of protection your lips have is saliva, which isn’t very effective at preventing dry, cracked and painful lips, which is why we need to give them a hand.

Soft and plump are signs of good, healthy lips which is why we all strive to have them. There’s a few ways you can keep them looking like this or even bring back their youthful density. Do this by protecting yourself from UV rays with a wide brimmed hat, eating a colourful plant-based diet and treating your lips to a nourishing serum.

As an example, Fitglow Beauty’s Lip Colour Serums contains vegetable collagen and plant antioxidants that focus on working together making lips look fuller, healthier, and assist in regaining a youthful appearance. Not only do you apply a gorgeous colour to your lips with the Lip Colour Serums, you’re also providing them with an evidence-based treatment.

Taking care of the skin on your lips is important and they deserve products that won’t just provide them with a bit of colour, but nourishment as well to keep them plump and youthful.

Want to learn more about these Lip Colour Serums? Let’s take a deeper look into the key ingredients and how they work together.

What’s that? The Organic Plump Complex

The organic plump complex is derived of certified organic phospholipids which are dispersed in a biomimetic certified organic formula. What all this means is that when it’s applied to your skin the water loving (hydrophilic) portions of the phospholipids will naturally migrate towards similar environments where they assemble into a multi-vesicular system. With this, the moisture in our skin causes these vesicles to swell which results in plumper lips and minimizing the appearance of fine lines. Since the vesicles penetrate the stratum corneum (aka the top layer of the skin) and bind with the moisture that’s there, they can inhibittrans‐epidermal water loss (TEWL) to increase hydration. So, what is that anyways?TEWL is the internal loss of water through the skin, and its critical to prevent and slow this down as it will lead to dehydration, dryness and uneven texture.

This phospholipid bilayer is critical to the cell’s ability to function, helping lips stay hydrated, full and supple even after the lip serum is removed which leads to long-long-term hydration and improvement.

Vegetable What? Vegetable Collagen

Collagen is fundamental in maintaining the structural makeup of humans, which is why it’s one of the most essential and fibrous proteins. You can find it in most major elements of the skin, bones and cartilage. Collagen forms insoluble fibres of high tensile strength that provide resis­tance and offer an elastic force over the skin.

Collagen is created by fibroblasts, which are cells found in the dermal layer of the skin and are re­sponsible for the production of collagen, elastin and fibronectin. These three con­nective proteins serve as structural support within the skin.

Fibroblasts incorporate collagen within the cell and release it through exocytosis, which is the dispersion of molecules through the cell membrane. Once outside the cell, collagen will self-assemble, creating the strong structure found in the skin.

What The Pom? Pomegranate Sterols

Pomegranate sterols naturally repair and replenish moisture barriers. They’re an excellent all-natural and botanical alternative to lanolin since it can hold 200% of its weight in water! Not only this, but it has a low coefficient of absorption making it better for protecting against trans-epidermal water loss (TEWL).

In a 4-week study using a high-resolution skin imaging ultrasounds, pomegranate sterols improved skin density by 29% after 24 hours and by 44% after 4 weeks when compared to the untreated control.

Why do we have it in our Lip Serums? On top of all the other reasons, pomegranate sterols are also oil soluble and give a beautiful gloss to the formula that’s good for you.

That Purple Thing? Organic Beet Extract

Beets are rich in polysaccharides and sugars which means these extracts can be used to effectively moisturize the skin. In addition to the polysaccharides forming a film to lock in moisture, beet sugars draw moisture from theair close to the skin where we need it most.

Phyto‐compounds in the root can enhance cell renewal, helping our skin feel soft and smooth. They also contain other compounds including Omega‐3,which can deliver anti‐inflammatory benefits. Also rich in anthocyanins andbetalain beet roots also act as potent antioxidants that can be used in skin care applications to prevent damage caused by free radicals and reactive oxygen species.Given the many nutritious properties that beets provide, it’s no wonder the root has traditionally been regarded as a “panacea” or “elixir of life” that cures diseases and prolongs life.

What did that mean? The Glossary

Melanin - the pigment that gives your skin, hair and eyes the colour that they are.

Capillaries - a very fine blood vessel that branches from a network.

Sebaceous glands - these glands secrete oily and wax-like matter that’s used to waterproof the skin.

Phospholipids - a class of substances that are a huge component to all of our cell membranes.

Phospholipid (lipid) bilayer - a thin membrane made of two layers of molecules.

Lanolin - a wax secreted by the sebaceous glands of wool-bearing animals.

Polysaccharides - a type of carbohydrate.

Phyto‐compounds - a wide variety of compounds that occur naturally in plants

Anthocyanins - This is found in a number of natural foods, and are responsible for the pigments that give red, purple, and blue plants their rich colouring.

Betalains - a class of red and yellow pigments found in plants, where they replace anthocyanin. 

Free radicals -toxic byproducts of oxygen metabolism which can cause damage to your body.

Reactive oxygen species - plays an important role in your body, and in times of environmental stress which includes UV exposure, these level can grow quite high and could end up damaging cell structures.
