FAQ – Ingredients, Safety and Certifications

Bioli is biotech skincare from the inside out, where bott ingredients and packaging are developed through biotechnology – with a focus on sensitive skin and consideration for the environment.

Our ingredients consist of bioactive enzymes and other biotech-derived ingredients, produced in controlled laboratory conditions using microorganisms such as bacteria, yeast and fungi. Rather than relying on extensive extraction from nature or petrochemical feedstocks, biotechnology enables us to develop carefully selected ingredients with high purity, consistency and stability, as well as targeted functionality.

This results in targeted and effective skincare with a gentle profile, particularly suitable for sensitive skin. Before launching, we conduct extensive testing to assess efficacy, safety and skin compatibility, including testing with people with sensitive skin. Slow but precise. Because we believe good skincare takes time.

Biotechnological production can also reduce reliance on agricultural land, water, energy and fossil resources, depending on the specific ingredient and production process.*

All ingredients are 100% biodegradable. The same applies to our packaging. Our bottles and jars are developed using microorganisms through biotechnology and are 100% biodegradable and OK compost HOME-certified. Our paper bags and gift boxes are FSC-certified.

No petrochemical-based ingredients. No plastic. No glass. Limited extraction from nature. We think through every step – from ingredient and product development to everyday use and end of life. The result is biotech skincare that is mild yet effective – developed with consideration for both skin and the environment.

*Resource use varies depending on the specific ingredient and production process.

Bioli skincare products are developed with a strong focus on safety, transparency, and sustainability, and are backed by multiple independent certifications and rigorous testing standards:

• AllergyCertified (Denmark): All Bioli products carry the strict Danish AllergyCertified label. Every ingredient is independently assessed by toxicologists and pharmacists for allergens, carcinogens, endocrine disruptors, and other potentially harmful substances, ensuring the lowest possible allergy risk.
  
• A-Kolbe rating (Denmark): All Bioli products hold the top “A-kolbe” rating from Denmark’s Consumer Council Tænk, meaning they contain none or only minimal amounts of substances of concern based on strict chemical safety criteria.
  
• Dermatologically tested for sensitive skin: All Bioli products are approved by an accredited laboratory and tested in independent patch studies on volunteers with sensitive or allergy-prone skin. Results show no irritation or allergic reactions, confirming they are non-irritating and skin-compatible.
  
• EU regulatory compliance: All Bioli products comply with the European Cosmetics Regulation (EC) No. 1223/2009 and are supported by a third-party Cosmetic Product Safety Report (CPSR).
  
• Vegan and cruelty-free: All Bioli products are 100% vegan and free from animal-derived ingredients such as beeswax, lanolin, collagen, keratin, and carmine. In line with EU law, neither products nor ingredients are tested on animals.
  

Packaging certifications:

• All Bioli products are packaged in FSC®-certified paper from responsibly managed forests.
  
• All Bioli products come in jars and bottles made from OK compost HOME-certified materials, designed to biodegrade under home composting conditions.
  

Together, these certifications and testing protocols ensure Bioli products are safe, gentle for sensitive skin, environmentally responsible, and compliant with the highest European standards.

Bioli's products are developed and manufactured in Denmark alongside leading skincare experts and scientists from a top Danish university.

They are fully compliant with the European Cosmetics Regulation (EC) No. 1223/2009 and backed by a third-party Cosmetic Product Safety Report (CPSR), ensuring the highest safety and quality standards.

For manufacturing, we work with a trusted Danish factory known for its reliability and commitment to sustainability. The factory uses recycled water and has upgraded to energy-efficient lighting, minimizing environmental impact while maintaining premium product quality.

Yes. All Bioli products are formulated with sensitive skin as the default, using only gentle yet effective, non-irritating ingredients and are free from fragrances. They are suitable for all skin types, including normal, dry, oily, combination, and sensitive skin.

All products are AllergyCertified and dermatologically tested on sensitive skin. In a study conducted under dermatological supervision with 25 volunteers who had a history of allergies or sensitive skin, none reported irritation or allergic reactions, confirming the products’ compatibility. Additionally, Bioli products are classified as non-irritating based on comprehensive skin compatibility tests.

Yes. All Bioli products are safe and suitable for sensitive skin conditions, including acne-prone skin, rosacea, perioral dermatitis, and eczema.

You can also read honest user reviews on the product pages to see real experiences and feedback.

Yes. All Bioli's products carry the Danish AllergyCertified label, one of the world’s strictest allergy safety certifications. Every ingredient is independently assessed by toxicologists and pharmacists for allergens, carcinogens, hormone disruptors, and other potentially harmful substances. Risk assessments cover purity, exposure, and concentration to ensure the lowest possible allergy risk.

All Bioli packaging – jars, bottles and droppers – is made through fermentation using microorganisms and is biodegradable and OK compost HOME-certified.

This means that after use, you can place your empty jar or bottle in your home compost, where it biodegrades without leaving microplastics behind.

If home composting is not available, the packaging can be disposed of as residual waste and sent for incineration. It is made from plant-based carbon rather than fossil-based plastic, so when incinerated, it releases carbon that is already part of the natural carbon cycle rather than fossil carbon. Compared with glass, it also does not require melting at very high temperatures to be recycled.

The packaging is not yet accepted as bio-waste. If it does end up there and in landfill, it will still biodegrade naturally and return to nature’s cycle – unlike conventional plastics, which can remain in the environment for hundreds of years.

Always follow local disposal guidelines.
