You've probably heard a lot of buzz about "preservative-free" skincare lately. Brands promoting their products as "all-natural" and "clean" by removing preservatives, but is that really what's best for your skin or your skincare routine? The truth is, preservatives play a crucial role in keeping your favorite skincare products fresh and effective. Without them, the luxurious creams and serums you know and love would become breeding grounds for bacteria, mold, and other microbes in a matter of days.
1. Preservatives in your products are not the enemy
Preservatives play an essential role in skincare product safety and effectiveness.. In reality, without any preservatives, they would become unsafe to use within days of opening due to contamination and spoilage. Once a product is opened and exposed to air, the countdown begins. Preservatives prevent microbial growth and help ensure your products remain effective and safe to use before their expiration date.
Skincare brands use preservatives judiciously and safely. So don't be afraid of preservatives - when used properly by conscientious brands, they're really doing you and your skin a favor!
2. Effective yet Safe Preservatives for you:
Most of the preservatives used in skincare are not capable of preserving a single product alone, i.e. they are either active against moulds and yeasts but not bacteria, or against bacteria and moulds but not yeasts. To overcome this trouble an effective preservative system is usually made up of several preservatives.
For Instance;
Organic acids and their salts, are gentle on the skin because they require an acidic pH (around 5 which is close to the pH of skin) to work effectively. This helps avoid over-sensitization to one single preservative, especially in leave-on products like moisturizers and serums. A few of these safe combinations include-
-
Sodium benzoate:
A salt of benzoic acid that's effective against bacteria, yeast and molds. It is often used with potassium sorbate to provide a broad spectrum activity on bacteria and especially on moulds and yeasts.
-
Potassium sorbate:
Derived from sorbic acid, it inhibits the growth of yeast, mold and fungi. This too is paired with sodium benzoate for broad spectrum activity.
-
Sodium Levulinate:
It is a sodium salt of levulinic acid, an organic acid that is derived from sugarcane. This is often paired with Potassium Sorbate.
-
Sodium Anisate:
Sodium anisate is the salt form of p-anisic acid. It is derived frim star anis. The combination of Sodium Levulinate and Sodium Anisate exhibits anti-microbial and skin conditioning properties.
3. Debunking Common Myths About Preservatives in Skincare
From claims of toxicity to the belief that "preservative-free" is always better, let's debunk these myths
-
Myth #1: Preservatives are toxic.
Consider preservatives in skincare products as ingredients in a recipe. Just as adding a dash of hot sauce can bring a pleasant kick to a meal, excessive amounts can overpower the taste and leave your tongue burning. Likewise, preservatives, when used in high concentrations, can irritate sensitive skin. However, responsible skincare brands follow strict regulations to ensure that preservatives are used in safe and appropriate amounts, providing protection without causing harm.
-
Myth #2: Preservative-free products are the best.
Preservatives are added to extend the product's shelf life while maintaining the safety. Without preservatives, skincare products can spoil quickly and become unsafe to use. Hence, "Preservative-free" simply means a shorter shelf life.
-
Myth #3: Preservatives are bad in food, so they must be bad in skincare products.
Food preservatives prevent spoilage and are regulated for consumption whereas skincare preservatives prevent microbial contamination and focus on topical safety.
Therefore, While both preservatives in food and skincare products serve the purpose of extending shelf life, it doesn't imply that they are identical in nature or function.
4. Why Do Preservatives Get a Bad Reputation?
Have you ever found yourself pondering the reasons behind the negative perception surrounding preservatives? We did too! And here are a few reasons why preservatives have developed a negative stigma:
Fear of "Chemicals"
The word "chemicals" frightens many consumers. But the truth is, everything in this world is made of chemicals! From the air we breathe, the water we drink to the food we consume everything can be broken down into molecules adn atoms. Likewise, Preservatives too are carefully regulated chemicals that are proven safe and effective when used properly in skincare & cosmetics.
Misinformation and Myths
There are many myths about preservatives being toxic, not safe because they are not natural. However, reputable scientific studies support the fact that preservatives are required to maintain the safety and efficacy of the product and prevent microbial growth.
Desire for "Natural" Products
Some people believe that "natural" products are always better and safer. But in reality natural ingredients tend to spoil more quickly and harbor harmful bacteria, mold, and yeast. All Preservatives do is prevent this contamination and extend the shelf life so you can enjoy your products safely.
