What are peptides – and why are they important for skincare?

Chances are you’ve heard this word floating around in the world of skincare, but aren’t too sure what it means, or why you need to make them a part of your routine. While you might not completely understand what peptides are (yet!) or how they work, they are an essential addition to many effective products that combat against common signs of maturing skin, such as:
  • Fine lines
  • Thinning skin
  • Lack of buoyancy or suppleness
  • Dryness

So how exactly do peptides help with these common skin concerns? Let’s take a look!

What are Peptides?

In its most basic explanation, peptides are amino acid chains that serve as building blocks for protein in the body. As organic compounds, amino acids help to create protein – and they serve other important functions for the skin including making sure that nutrients are properly transported, as well as providing proteins the necessary structures needed to remain healthy and viable.

After amino acids combine, they create chains known as peptides. These chains can range in length from short to long, but longer amino acid chains serve as the foundation for proteins.

Protein is an important component in skin – while most of us focus on consuming enough of it as part of a healthy lifestyle, protein is a major part of what makes up the skin, tissues and organs throughout the body! Collagen is one such vital protein – in fact, between 75 and 80 percent of the skin is made up of collagen. In addition to elastin and keratin, collagen is a crucial component in keeping skin healthy and supple; however through the natural aging process and the environment, the body’s ability to maintain ample collagen levels gradually decreases over time, leading to the development of fine lines, loss of skin firmness and thinning skin.

Collagen is typically what’s responsible for that youthful glow – when skin is younger, collagen production is at a much higher level! This protein is what gives skin smoothness, suppleness and a radiant glow.

So to recap, amino acids create peptides, and peptides are responsible for forming proteins, such as collagen. Since the aging process naturally reduces collagen production, finding the right skincare products to help restore collagen into the skin is ideal – which is why peptides are becoming even more popular in the world of skincare!

Peptides and Skincare

One way to fight back against the natural decline of collagen is to choose skincare products that are packed full of peptides and other skin-friendly ingredients. In creams and serums, the use of short-chain amino acids helps reduce signs of aging, such as fine lines.

Why short-chain amino acids?

These chains, as opposed to the longer amino acid chains, allow peptides to effectively penetrate into the skin’s layers, encouraging the skin cells to ramp up the level of collagen production. Essentially, when you apply peptides to the skin topically, you’re giving cells the hint that it needs to do better in the collagen production department – thus prompting skin cells to develop collagen for areas that need it the most.

In addition to reducing common signs of aging, peptides are also very helpful in repairing skin, especially when experiencing some skin conditions such as dermatitis.

How to Use Peptides in a Skincare Routine

No matter what your age, peptides are a great addition to any skincare routine. Environmental factors, such as oxidative stress and pollution, also begin to break down collagen production early on – so the use of peptides helps firm and protect skin from exposure to free radicals and other stressful factors.

Incorporating peptides into a skincare routine is as simple as adding a serum with your daily moisturizer, or adding an eye cream to help reduce fine lines that typically develop around the eye’s thin and delicate skin.

PeptiDerm Firming Serum contains a multiplex of peptides, all of which work together to increase the skin’s elasticity and firmness. In addition to reducing the appearance of fine lines, the Firming Serum also protects the skin against environmental factors that speed up the aging process! Simply smooth a dropper full of serum to the entire face, neck and decollate, then follow up with your favorite hydrating moisturizer.

For those with mature skin or if you find that your skin is losing firmness, PeptiDerm Moisturizing Cream is packed full of beneficial peptides and other hydrating ingredients to provide skin a healthy and supple texture – in addition to infusing plenty of moisture and oxygen to fight back against dryness, giving your skin that radiant glow you want.

Move over UVA, there’s a new threat in town and it’s coming at you from your electronic devices! New research now indicates that HEV (high energy light, also known as “blue light”) may actually be as damaging to your skin as the sun – and it’s all around us. It’s hard to escape cause it’s coming from our laptops, tablets, cell phones, TVs and even our LED lighting.

Not quite ready to unplug? You can still fight back.

Although most of us are well aware of the damage to skin caused by UVA and UVB and, although certainly controversial, more and more evidence suggests that light emitted from our tablets, cell phones, computer screens, etc. may also be prematurely aging our skin.

High energy visible light, also known as blue light, is a high frequency wavelength emitted by TV screens, smartphones, tablets and computers. Although highly controversial, studies suggest that a veritable smorgasbord of unpleasantness such as sleep disruption, damage to your eyesight, premature aging and increased risk of hyperpigmentation are some of the suspected effects caused by chronic exposure.

Emerging studies documenting this phenomenon presented evidence that chronic exposure (which most of us encounter daily) caused a significantly higher frequency of hyperpigmentation in even darker skin types, with visibly affected areas lasting up to three months after initial exposure. In addition, one study also noted a significant increase of keratinocyte necrosis, or thickened layer of dead cells on the surface of the epidermis, giving a dull, dry lackluster appearance to the skin. Finally, it is believed that HEV exposure may weaken the skin’s barrier function, making it more susceptible to free radical damage and thus, premature aging.

Shields up!

The bad news is in – your phone, tablet and laptop can damage your skin. The good news? You can fight back.

What to do?

Protect, protect, protect.

Remember that old Ben Franklin axiom “an ounce of prevention is worth a pound of cure?” It’s so much easier to prevent damage from exposure than it is to correct it once the damage has occurred. Exactly as you would protect your skin against other forms of radiation exposure (we’re talking UVA and UVB here) a mineral based, full spectrum sun protectant is your best friend. Sanitas Solar Block is the perfect finishing step to your morning skincare routine and provides a full spectrum dose of non-toxic protection in a base of antioxidants. We’ve said it before and we’ll say it again: wear your sun block every day.

Fight back with topical antioxidants.

Need a quick refresh on free radicals? These disruptive, free-wheeling agents of decay are caused by mutation in cellular atoms which in turn, cause subsequent mutation that leads to the brand new free radical attacking healthy cells. Think of them as the cellular zombie apocalypse. One free radical can cause a cascade of damage that can lead to everything from prematurely aged skin to even cancer.

But you can fight those cellular zombies. A high dose of lipophilic vitamin C (Sanitas Vita C Serum contains 25% vitamin C) does a standout job of combatting free radical damage by helping filter out harmful light rays and strengthening the skin from the inside out. The benefits of vitamin C can be significantly bolstered by adding vitamins A, E, K and D (Sanitas VitaRich Serum has a 100% active, antioxidant blend) to the mix.

Diet can help! 

Believe it or not, the health of your skin is heavily influenced by what you eat. The best prevention strategy against the harmful effects of free radicals is a well-regulated lifestyle. Eating a diet rich in vitamin C, carotenoids (plant pigments) and omega fatty acids all play an important role in nutritional skincare. So load up on foods like salmon and avocados (healthy fats), strawberries and broccoli (high in vitamin C) and carrots and yellow peppers (loaded with carotenoids)to help fight those free radicals from the inside out. Of course, sometimes it’s hard to get all of those fruits and veggies in every day, so supplementing with antioxidants and Sanitas EFA complete can help.

Does blue light age your skin? Blue light comes from every electronic device we have, from our computers to our phones. What is the effect from blue light on your skin? Learn more in this article by Sanitas Skincare.
This thing? It’s called a book.

We get it – you can’t unplug from the day-to-day necessity of being online, but you can take an active, mindful approach to managing your blue light exposure. Use earbuds instead of holding the phone up to your face. Your bedroom isn’t a charging station – it’s for rest and reprieve. Try disconnecting from all devices 30 to 60 minutes prior to turning in and swap your PM Netflix lineup with a good, old-fashioned book. Reading helps slow the mind at the end of the day leading to a better night’s sleep and by default, healthier skin.

You could go big and ditch your devices altogether but for most of us, that’s just not realistic or feasible. Instead, try to limit your exposure as much as possible. Do you really need to check your Insta feed or email all day long? Of course not.
