How Does Our Skin Take In Substances?


Dermal absorption is the ability in which our skin absorbs a substance. There are three main types of absorption: permeation, intercellular, and trans appendageal. Permeation happens when chemicals travel directly through the skin cells. Intercellular absorption is due to the chemical traveling between the cells. Trans appendageal is the absorption through glands and hair follicles. Dermal absorption is largely based on the size of the molecule in which the skin is being exposed and what other ingredients are acting as vehicles for the chemical.

Also, different areas of the skin have different absorption capabilities. The thinner skin of the face absorbs much more easily than the thick skin on the soles of the feet.

How Do Low Quality Ingredients Hurt the Body?


Often ingredients have been added to daily use items, like skincare, for the performance of the product but can negatively affect the overall health of the body due to the absorption into the bloodstream. These ingredients are easy to access and used as quick fixes because of their capabilities to enhance the formula. Here are a few examples:

Sulfates

Sulfates are foaming agents used in cleansers or act as emulsifiers used to keep ingredients blended. They aid in the penetration of other ingredients. They are known as a common irritant that can cause peeling or dryness and tightening of the skin, ultimately compromising the integrity of the natural barrier. This ingredient is often found in face wash, shampoo, toothpaste. A common sulfate is sodium lauryl sulfate. 

PEG compounds

PEG compounds act as humectants for moisture retention, surfactants as foaming agents, penetration enhancers, etc. PEGs are also endocrine disrupters that can cause hormonal imbalance and birth defects. They are commonly found in soaps, lotions, face creams, makeup, etc.

The idea behind using these ingredients is to increase the performance of the product or the efficacy of active ingredients within a formula. Some ingredients cause adverse effects on the skin and weaken the skin’s natural barrier. If a consumer is using skincare that is meant to repair the health of the skin but the ingredients within that skincare are consistently compromising the barrier, the consumer is in a never-ending cycle that most likely will not give the results they are looking for. These harmful ingredients are just a shortcut. 

There are other ingredient options, even chemicals, that are both safer for the body and just as effective from a performance standpoint. These quality ingredients are sometimes more difficult to access, or it may take time to identify the best option. Hence, the abundant use of the ingredients such as the ones outlined previously that are readily available.

KUL Empowers You Through High Quality Ingredients


The KUL focus is entirely based on the quality of the ingredients and the thoughtfulness of the formulas to provide results that are both unparalleled and safe. KUL products are all PEG and sulfate free. Being aware of the quality of the ingredients within skincare or the commitment to the quality of a company can empower the consumer to make the best decisions for themselves.
