Niacinamide is one of the most widely used forms of vitamin B. It is a precursor to the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), both of which are elemental to the processes that repair and regenerate skin cells. Niacinamide provides countless skin benefits, including aiding DNA repair and skin homeostasis. As it is stable and water soluble, niacinamide can be easily blended into cosmetic and skin care products. Facetheory uses niacinamide PC, an enhanced form of niacinamide containing a significantly reduced amount of nicotinic acid, a substance associated with unpleasant heat sensation.
Niacinamide targets a wide variety of skin concerns, including acne, pimples and uneven skin tone. Research shows that niacinamide helps shield the skin against UV rays, making it ideal for use during exposure to sunlight.
1. Skin tone
A study conducted by the British Journal of Dermatology concluded that niacinamide is an effective skin-lightening compound. Niacinamide inhibits melanosome transfer from melanocytes to keratinocytes, thus reducing hyperpigmentation and balancing out uneven skin tone.
2. Protection and prevention
Research shows that niacinamide is a highly potent and well-tolerated ingredient that helps to prevent damage from UV rays and provide protection against other environmental aggressors.
Niacinamide combats the effects of urban pollution by reinforcing the skin’s barrier, balancing out uneven skin tones, and reducing discolouration. Niacinamide protects skin against moisture loss, increases cell viability, and minimises damage caused by water contamination and unfiltered ultraviolet light from the sun.
3. DNA repair
Niacinamide has proven restorative qualities. Topical niacinamide assists in DNA repair by supplying cells with the energy needed by enzymes to unwind the DNA strand, replenish the nucleosides, and then rewind the strand. This process helps to repair damage caused by UV exposure and other environmental threats.
Exposure to unfiltered sunlight is associated with premature signs of skin aging. NAD and NADP, two coenzymes which play a vital role in cell metabolism, also become depleted as we age. Niacinamide stimulates collagen synthesis, which helps skin to retain its elasticity and firmness, thus diminishing the appearance of fine lines and wrinkles. Studies have indicated that people reported seeing significant results within 8 to 12 weeks.
5. Blemish care
Niacinamide regulates the production of sebum, thereby preventing the formation of blackheads, pimples, acne, and enlarged pores. It also reduces inflammation, thus minimising the redness caused by acne lesions and eczema.
Niacinamide can be used twice a day on all skin types, including sensitive, oily or acne-prone complexions. Apply it to clean skin in the morning and at night before your favourite Facetheory sunscreen and moisturiser. As it protects the skin against moisture loss and shields against damage from UV rays and air pollution, it is especially recommended for use during the day to keep skin hydrated and protected.
