Absolutely! Our 90-Day Money-Back Guarantee is a testament to our confidence in DuoGen products and our commitment to your satisfaction.

At DuoGen, we're committed to creating 100% vegan and cruelty-free options.
Absolutely not. We ensure that none of our finished products, ingredients, or formulas are tested on animals. Our commitment to cruelty-free practices is unwavering, reflecting our dedication to ethical beauty standards.
Not now, not ever. As a small, privately owned business, our heart is set on upholding the highest standards of animal welfare. We believe in kindness, not just in beauty but in all aspects of our business.
Supporting our community is not just a habit; it's a passion. We proudly donate a percentage of every sale to Women's Aid UK, aiding women and children affected by domestic violence. This commitment to giving back is integral to who we are and what we stand for at DuoGen.
At DuoGen, we believe in simplicity and sustainability. Our packaging philosophy focuses on minimalism and efficiency, keeping costs reasonable while investing in high-quality formulations. Our serums come in recyclable glass packaging, and our creams and moisturisers are housed in recycled plastic. It's our way of caring for you and the planet.
Our subscription program is temporarily suspended due to high demand. We recommend stocking up on your favourite items.
Our best sellers include the Hyaluronic Acid Serum, Triple Vitamin C Serum, and Retinol Serum. For beginners or those with sensitive skin, we recommend starting with the Vitamin Rich Serum and 5% Niacinamide Daily Moisturiser.

Product

For optimal efficacy, store all DuoGen products in a cool, dark place. Products with active ingredients sensitive to sunlight are specially packaged in amber glass bottles or black packaging for added protection. For other products in clear packaging, which are not light-sensitive, this storage method remains a best practice to maintain their quality.

At DuoGen, we're dedicated to ensuring that each of our products not only meets but exceeds your skincare expectations. Understanding the shelf life and optimal usage of our products is key to maximising their benefits. Like the best ingredients in your kitchen, the fresher your skincare, the more effective it is. Here's how to make the most of our range:

  • Moisturisers: Reach their peak performance within 12 months of opening. We formulate them to maintain their hydrating qualities throughout this time.
  • Amber Bottle Serums: These are specially crafted with sensitive active ingredients, best used within the first 6 months for maximum efficacy, but they remain effective for up to 12 months.
  • Clear Bottle Serums & Creams: Designed for a longer shelf life, these are ideal to use within 12 months, and safe for up to 24 months, offering you sustained skincare benefits.
  • SPF Products: For the best sun protection, we advise using them within 12 months, as their protective properties are most potent during this period.
  • Cleansers and Toners: Essential to your daily routine, they are effective for 12 months post-opening, ensuring your skin receives consistent care.

Be sure to look for the “period after opening” symbol on our packaging for product-specific information. Proper storage is crucial — keep these products in a cool, dark place away from direct sunlight to preserve their quality and effectiveness.

Our 30ml products typically last up to 4 months with daily use. The larger 50ml and 100ml sizes will last even longer, depending on how frequently you use them. Keep in mind, that frequent use, like applying our Hyaluronic Acid Serum twice daily, may shorten this duration.
We do not offer product samples at this stage. However, we have a 90-day money-back guarantee on all our products, giving you the confidence to try them risk-free.
Our products, suitable for all skin types including sensitive skin, are generally safe during pregnancy and breastfeeding. However, we recommend consulting your GP or healthcare professional before use, as each individual's situation is unique. For added caution, you might consider a patch test. Our full ingredient list is available on each product's information page. Please note that DuoGen products are fragrance-free and do not contain essential oils, aligning with our commitment to pure, gentle skincare.
Absolutely. Our SPF products undergo rigorous testing in line with the international standards ISO 24444 and ISO 24443. ISO 24444 specifically focuses on in-vivo SPF testing, which means it assesses the product's effectiveness in protecting against UVB rays – the primary cause of sunburn. This testing involves carefully monitored human trials to determine the Sun Protection Factor (SPF), ensuring that when you use our product, you receive a scientifically verified level of protection against UVB radiation. Additionally, ISO 24443 is the in vitro UVA test, demonstrating that our product provides adequate UVA protection as well.
To do a patch test, apply a small amount of the product to your neck or under your wrist. If you have sensitive skin or are prone to reactions, consider consulting a healthcare professional. Discontinue use immediately if sensitivity occurs.

To maximise the benefits of our products, follow this simple routine:

Daytime:

  • Brightening Gel Cleanser: Massage onto damp face, and rinse off.
  • AHA & BHA Clarifying Toner: Apply gently over the face and neck.
  • Serums: Apply Triple Vitamin C, followed by Hyaluronic Acid Serum.
  • Moisturise: Use your preferred moisturiser.
  • Peptide Eye Cream: Dab gently under the eyes.
  • SPF 50+ Daily Moisturiser: Apply liberally before sun exposure.

Nighttime:

  • Brightening Gel Cleanser: Start with a gentle cleanse.
  • AHA & BHA Clarifying Toner: As per morning routine.
  • Retinol Serum: Apply carefully, avoiding sensitive areas.
  • Vitamin Rich and Hyaluronic Acid Serums: As per morning routine.
  • 5% Niacinamide Daily Moisturiser: Apply to face and neck.
  • Peptide Face & Neck Night Cream and Eye Cream: Finish off your routine.

Always patch test first and consult a healthcare professional if you have sensitive skin. Adjust the routine based on your specific product availability.

We use amber bottles for our products primarily to protect their contents from sunlight and UV rays. While transparent strips on bottles might provide a way to view the contents, they would also allow light to penetrate, risking the degradation of the product inside. Therefore, to maintain the integrity and effectiveness of our products, we use fully opaque amber bottles for optimal protection against light exposure.

Due to our same-day dispatch policy for rapid delivery, we strongly recommend double-checking your order before submission. Once an order is placed, it's immediately processed for shipping, making it very challenging, often impossible, to accommodate cancellations or modifications. Your attention to detail helps us maintain efficient service.

Accuracy in providing your shipping address is crucial due to our same-day dispatch. This quick processing means that changing the address post-order placement is typically not feasible.

For adjustments after dispatch, Royal Mail may offer limited options such as:

  • Choosing a new delivery date,
  • Redirecting to a neighbour or
  • a Safeplace, or parcel collection.
We currently do not deliver to P.O. Boxes. Please provide a standard residential or business address to ensure your DuoGen products are delivered without any hitches.
