The Necessity of Removing Parabens from Skincare Products
Written on
Chapter 1: Understanding Parabens
Parabens are commonly highlighted as substances to avoid when choosing skincare products. According to Kathryn St. John, the communications director at the American Chemistry Council, parabens are defined as follows:
"Parabens are derived from a chemical known as para-hydroxybenzoic acid (PHBA), which naturally occurs in various fruits and vegetables like blueberries and carrots."
The term "paraben" originates from para-hydroxybenzoic acid (PHBA). The chemical structure of PHBA includes an aromatic benzene ring, which is essential to its makeup. A report indicates that parabens have been safely used for nearly a century as preservatives in food, pharmaceuticals, and cosmetics.
Parabens, including methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and isobutylparaben, can be found in products such as cosmetics, moisturizers, and hair care items. Contrary to some claims, most leading deodorant and antiperspirant brands have removed parabens from their formulations.
Preservatives like parabens are utilized in cosmetics to prevent microbial growth (such as bacteria and fungi), ensuring both consumer safety and product longevity. In the food industry, parabens have served as preservatives for over five decades, naturally occurring in certain fruits like blueberries and used in a variety of products including confectionery and snacks. While parabens themselves do not pose direct harm, their interaction with environmental factors is worth examining.
When exposed to sunlight, our skin can develop a nice tan if the exposure is moderate; however, excessive sunlight can lead to sunburn, which is quite uncomfortable. Unfortunately, ultraviolet (UV) rays from the sun can cause photosensitization of parabens:
What’s the Difference Between Ultraviolet Irradiation for Sterilization and Skin Cancer?
The science behind this phenomenon may be surprising, yet it is fundamentally interconnected.
The aromatic rings found in the benzoic acid structure of parabens that we apply to our skin for UV protection are sensitive to UV irradiation, releasing electrons during photosensitization.
An intriguing fact is that our cellular mitochondria can also leak electrons during energy production, forming reactive oxygen species (ROS):
Antioxidant Protection in the Body Begins from Within the Cell
It’s important to recognize that our cells are capable of producing their own antioxidants.
If mitochondrial electrons can create ROS, could photosensitized electrons not do the same? The presence of ROS significantly influences the biochemical processes of oxidation and reduction within our bodies, potentially leading to oxidative stress and damage to various biomolecules.
Oxidative Stress: An Electrochemical Concept
What effects can uncontrolled electron transfer have on our health?
These biomolecules include the DNA within our cells. Oxidizing DNA can alter its structure, leading to mutations. Such mutations are problematic, especially if the immune system is ineffective in eliminating these defective cells:
Our Bodies: Efficiency in Action
This concept ties back to autophagy, the body’s process of removing damaged cells.
A simple yet effective solution is to avoid skincare products containing parabens. However, it’s also essential to consider how we can protect ourselves from the oxidative effects of these compounds. Prioritizing our dietary intake is key to maintaining skin health and preventing premature aging:
The Biochemical Mechanisms Behind Aging Symptoms
While these effects may seem complex, they are not beyond comprehension.
The best chemical strategy for managing pro-oxidants is to ensure adequate antioxidant intake. Regardless of the presence of parabens, consuming antioxidants is crucial for supporting overall biochemical health.
