Increases Cellular Immunity
Niacinamide builds the immunity of your skin.There are immunity-stimulating cells in your skin known as Langerhans cells. They are responsible for cellular protection and repair. Langerhans cells send out special signals to stimulate T cells & B cells — immediately after sensing any kind of damage or infection in the skin. The immune cells capture the invading pathogens such as bacteria and viruses while they fight off injuries like cuts and scrapes. The body then amasses a great force of inflammatory cells to fight off invaders by creating an allergic reaction or forming scar tissue to protect from infection.
T cells & B cells protect and repair your skin, as they clean up damaged DNA and prevent cells from becoming pre-cancerous. However, when the Langerhans cells are exposed to the sun/UV radiation (and even worse when you burn it), Langerhans cells retreat into the bloodstream, leaving the skin exposed and vulnerable. Research has shown that topical Vitamin B3 (niacinamide) can stop this reaction therefore, strengthening the skin’s immunity.
Niacinamide is a powerful antioxidant that strengthens and (CUT OFF HERE) stabilizes the epidermis. If you want to delay the signs of aging on the skin and protect it from further damage from pollution, sun exposure, radiation, toxic chemicals, smoke and microparticulates, you should be using topical antioxidants on the skin. (This includes Vitamin C.) Niacinamide cleans up and neutralizes the damaging free radical molecules that are created by these environmental factors. Niacinamide can aid in the removal of aging, damaging free radical molecules that are created by these environmental factors.
Vitamin B3 and Hydration
Niacinamide improves epidermal barrier performance. Everything about your skin is better when the epidermal lipid barrier is functioning at its peak. Your lipid barrier helps retain moisture, keeps it hydrated for longer and will protect your skin from the harshness of the environment. Hydrated skin always looks more plump and younger. As we age, the skin’s ability to retain moisture decreases significantly which is why fine lines and wrinkles begin to appear. Niacinamide has the ability to increase the production of ceramides – vital lipid-holding packets within the layers of the skin. Ceramides help keep skin strong and stops moisture from escaping. Niacinamide can help maintain your skin's barrier, keeping it hydrated and less sensitive; and it is a wonderful vitamin for conditions such as rosacea and sensitive skin types where the barrier is considered compromised and reactive.
Niacinamide, Hyperpigmentation, Tanning & Uneven Skintone
Niacinamide can be effective at reducing pigmentation and age spots by slowing down melanin production, which is one of the known 14 pathways of hyperpigmentation. The transfer of pigment (melanosomes) from your melanocytes to the surrounding skin of your epidermis is known as a tan. However, over time, this activity becomes dysfunctional, and many of us end up with uneven, blotchy pigmentation rather than the golden tan of our youth. If your skin has become susceptible to hyperpigmentation, then Niacinamide will assist in the reduction of uneven pigmentation by slowing down the transfer of melanin to your skin’s epidermis.
It also protects your skin from infrared light. Niacinamide protects the skin from the heat and heat of the sun. Along with the damaging effects of UV radiation, the heat of the sun activates free radicals and stimulates an overproduction of pigmented cells. Heat stimulates melanin (the dark pigment in your skin) and is yet another pathway which creates unwanted spots. Heat in the skin can also be a problem for those of you who have hormonal acne, and hormonal hyperpigmentation and melasma.
Niacinamide and Acne/Oily Skin
Vitamin B3 also boasts antimicrobial and anti-inflammatory properties and has been shown to effectively treat some cases of acne. Niacinamide is great for regulating sebum (oil) production, too! When your skin retains its natural moisture with a well-functioning lipid barrier, the natural oil flow of the skin becomes controlled. So, if you have oily skin, over cleansing and stripping toners will exacerbate the problem. Whether oily or dry, (lack of oil), niacinamide helps regulate these skin conditions.
Keeps Pores Cleaner
Another awesome benefit of niacinamide is the fact that it keeps your pores clean and doesn't allow them to fill up as fast. Unless you are having regular facials with professional exfoliation, you will need some means of keeping the skin congestion-free. Your pores (follicles) do not have muscles. PORES DO NOT CONTRACT AND EXPAND. While some people think that a toner creates smaller pores, what it actually is doing is pulling out surface hydration and tightening the skin temporarily via dehydrating the surface layers (why do you want to dehydrate the skin?). When your skin surface and pores become congested, that waxy keratin and dead skin cell mixture will fill the pores and dilate them. Over time, when dilated, they will lose their integrity and enlarge. That's why it is important to have proper exfoliation, and maintain it between clinical facial exfoliation services. Once the pores are stretched/dilated, there really is no way to tighten them up again. Prevention, prevention, prevention. A word about home exfoliation: scrubbing your skin only removes part of the surface congestion. Deep pore congestion goes deep - like a cork stuck in the neck of a wine bottle. Over-exfoliation damages the barrier making it more susceptible to a compromised barrier, creating further problems.
Improves redness and blotchiness in the skin
With an improved epidermal lipid barrier, the skin’s natural ability to protect itself from external aggressors becomes vastly improved. With daily application of Niacinamide, improvements in skin's structure will increase, making the skin less prone to redness, blotchiness and other sensitivities.
Improves Collagen & Elastin Production
Boosting skin with Vitamin C and niacinamide minimizes lines and wrinkles by boosting collagen production. With improvement of the skin’s lipid barrier comes an increase in cell differentiation which contributes to better synthesis and formation of collagen and elastin.
Improves Dull and Sallow Skin, Making Skin More Luminous
While many antioxidants prevent damage caused by oxidative stress and AGE’s. Oxidative stress, leads to chronic inflammation, which, in turn, can cause collagen fragmentation and disorganization of collagen fibers and skin cell functions, and thus contribute to skin diseases including cancer. AGEs production in skin cells is known to promote stiffness and loss of elasticity through their buildup in connective tissueAs time goes by and with the constant exposure to free radicals and glycation, the skin can appear dull and sallow with a sad loss of radiance. You don’t want that! Niacinamide goes one step further and reverses the visible signs. Niacinamide reduces the negative impact of oxidative stress and improves the skin’s ability to fight back
Sometimes temporarily stimulating in the beginning, the gentle nature of vitamin B3 makes it suitable for all skin types and ages, benefitting healthy or challenged skin conditions. With so many beneficial properties, adding this serum to your daily routing is highly recommended.
