Nasturtium Officinale Seed Oil, Nasturtium Officinale Oil
- Nasturtium Officinale is Watercress. A groundbreaking skincare study showed Watercress uniquely promotes Collagen III in the dermal cells of the papillary dermis skin layer.  This makes skin smoother, resilient, youthful, and elastic. Watercress is also an antioxidant full Vitamins A, C, E, K, and Copper.  Copper restores skin elastin. Elastin gives skin its’ youthful bounce and the ability to spring back. Copper also encourages healthy hair follicles. The Vitamin K in Watercress can reduce brown and blue-tinged under-eye dark circles caused by leaking capillaries. Watercress also contains Vitamins A and C to fight free radicals.
- Neem Seed Oil is particularly effective on healing sun damage and restoring moisture.Â Â It deeply penetrates theÂ skinÂ to enhance elasticity, smooth wrinkles, and stimulate collagen production.
On hair, Neem removes sebum, dandruff, Â dry skin flakes, and eczema that can all impair hair growth. It promotes hair growth by improving scalp health, providing a soothing, protective barrier. It also makes hair soft. Neem has an odor, it is far less noticeable within a product than when used alone.
- Neutral Protein Filler
- Neutral Protein Filler is a concentrated wheat protein liquid added to hair dye mixes to compensate for porous hair or hair that has been recently color corrected. Commonly used in DIY hair coloring and manufactured dyes to obtain even saturation results. Neutral Protein Filler can also be used as a diluted protein treatment for severely damaged hair too compromised to re-color.
- Niacinamide, nicotinamide
- Niacinamide is a Vitamin B3 derivative. Gentler than Retinol, researchÂ shows Niacinamide addresses many skin issues. It is a very good addition to an anti-aging regimen because it promotes collagen, addresses a loss of elasticity and reduces redness. It fades acne scars and brightens the skin.  It reduces the inflammation of rosacea and other inflammatory skin conditions  An effective brightening and lightening tool all own its’ own, when paired with Vitamin K results in brighter and firmer skin. It decreases sebum production,  fine lines and enlarged pores. It inhibits melanin production in hyperpigmentation.Â  Niacinamide reduces the impact of environmental damage because it improves skinâ€™s barrier and Ceramide levels .
- Nitric Oxide
- Nitric oxide is a new anti-inflammatory and antimicrobial that reduces sebum.  It reduces PropioniÂbacterium acnes, a key bacteria of acne formation . Unlike chemical antibiotics, the body doesn’t build a Nitric Oxide resistance. It remains effective for long-term acne treatment.  Studies show Nitric Oxide is gentler than Retinol for treating acne.  Nitric Oxide works from the bottom of a pimple upwards. This treats even deep cystic acne without excess surface irritation.

- Non-comedogenic is when an ingredient or product is unlikely to clog pores and create a whitehead or blackhead.
