Do Natural Preservatives Really Work in Skincare?

As more consumers become conscious of what they put on their skin, a common question arises: Can natural preservatives truly protect skincare products from spoilage?

The answer is: YES

But with some requirements. 

What Are Natural Preservatives?

Natural preservatives are substances derived from plants, minerals, or microorganisms that help prevent product deterioration caused by bacteria, mould, yeast, or oxidation. Unlike synthetic preservatives such as parabens, natural alternatives are considered safer on the skin and less harmful to the environment.

Examples of Natural Preservatives:

• Vitamin E (Tocopherol) – A powerful antioxidant that helps delay the oxidation of oils.
• Grapefruit Seed Extract – Offers antimicrobial support, although its effectiveness can vary.
• Rosemary Extract – Helps slow down oxidation and spoilage.
• Leuconostoc/Radish Root Ferment Filtrate – A naturally derived antimicrobial created through fermentation.
• Potassium Sorbate & Sodium Benzoate – Mild, food-safe preservatives often used in natural skincare, though they may be synthesized.
• Essential Oils – Certain oils, such as tea tree or lavender, provide antibacterial properties, but they must be used carefully and in the correct concentration.

Which Natural Preservative Is Used in Botanical Bliss Natural Skincare Products?

At Botanical Bliss Natural Skincare, we use Leuconostoc/Radish Root Ferment Filtrate as our natural preservative of choice. This ingredient is made by fermenting radish roots with Leuconostoc kimchii—a strain of beneficial bacteria commonly found in traditional fermented foods like kimchi.

The fermentation process produces antimicrobial peptides, which help protect skincare formulas from bacteria and fungal growth. This makes it a smart option for preserving products, especially those that contain water.

Benefits of Leuconostoc/Radish Root Ferment Filtrate:

• Hydrating – Naturally rich in skin-conditioning peptides. 
• Broad-spectrum antimicrobial protection – Fights a variety of microorganisms that can spoil skincare products.
• Eco-conscious – Fully biodegradable and a sustainable alternative to synthetic preservatives.
• Gentle on skin – Sustainable for sensitive and reactive skin types.

Do Natural Preservatives Work as Well as Synthetics?

While natural preservatives are effective, they typically have a shorter shelf life and are more sensitive to environmental factors like heat and humidity. They also require meticulous formulation, including:

• Controlled pH levels
• Clean, airtight packaging
• Small-batch production for freshness

At Botanical Bliss, we formulate our products with these factors in mind ensuring that you receive a product that is both safe and naturally preserved, without harsh synthetic additives.

Final Thoughts: Nature Can Protect, Too

Preservatives are essential in skincare. Without them, even the purest product can become unsafe. While natural preservatives aren’t as long-lasting as synthetic ones, they can work beautifully when used correctly and with care.
