Skincare ingredients change and improve so fast, it can be very hard to keep up with what these ingredients are AND what they do. I will attempt to briefly describe some of the most used ingredients and how they can help your skin. This is Part 3, letters N-Z. Let’s get started.



This ingredient helps to prevent melanin from rising to the skin’s surface and causing sunspots. It also helps moisturize the skin and in some cases can prevent inflammation and free radical damage. It is a B vitamin and may not be a good choice for people who are acne prone.



These are thick ingredients, such as petrolatum and will slow the evaporation of water from the skin’s surface, boosting hydration.



These are preservatives used to protect cosmetics from bacteria and fungi growth. They have been controversial because they are similar to estrogen. However, their danger has been proven unfounded. They are FDA approved and have been used in foods and cosmetics for years.


WOW, Just WOW. These are chains of amino acids found naturally throughout the body that sends messages to the cells to promote collagen growth and cell repair. There has been so much new research in this area in the last few years and, in professional formulated skin care, they are now producing amazing results in skin repair. I carry an amazing line of peptides that truly do what they say they do.



This is a filler that is made from Hyaluronic Acid that doctors use to replace lost volume in the skin. It is injected into the skin.It is very effective on the lips.


This is a catchall phrase that describes all topical vitamin- A derivatives used in skin care.


Retinol is used in many anti-aging products to speed up exfoliation, epidermal repair and the production of new collagen. However, over the counter formulas do not have the proper amount to really be effective. Again, use professionally formulated retinol to get the results you want. I have used retinol since they first came out and they simply are AMAZING.


Salicylic Acid

The main beta hydroxy acid used in skin care products. It removes excess oil and dead skin cells. It is used in some acne care products. 


A liquid product that contains high concentrations of active ingredients and has a superior penetration of the skin’s surface. Again, the correct formulation is critical here.

Sodium Lauryl Sulfate (SLS)

This is a detergent agent that removes oil and generates lather. SLS can be very harsh and pore clogging to people who are acne prone and will take the color out of colored hair.

Stearyl Alcohol

This is a fat that binds ingredients in creams and cleansers and gives them that silky texture.


Titanium Dioxide

This is a sunscreen ingredient that is physical sunblock, means it reflects UVA and UVB light, keeping them out of the skin. I love physical sunscreen. This is what I wear myself.


This is a radio-frequency machine used to penetrate into the deep layers of the skin and generate heat that stimulates the formation of new collagen to firm the skin.


UVA rays

This a wavelength of ultra-violet light that leads to skin damage by destroying existing collagen and elastin in the skin and undermining the skin ability to create more of each. They also cause skin cancer and they are being generated in tanning beds. Protect yourself and wear SPF daily and for GAWD sack stop tanning beds!

UVB rays

The high-energy wavelength of ultraviolet light that leads to dark pigment in the form of tanning, freckles and age spots, and of course sunburn. STOP them from damaging your skin and use SPF daily.


Zinc Oxide

This mineral physically blocks UVA and UVB light from penetrating the skin. It doesn’t irritate the skin and is very effective. The new zinc oxide used to be heavy and white on the skin, but new micronized formulations are now light and sheer. I prefer this in my SPF.
