Is Blissy's silk hypoallergenic? You might wonder about this if you’re among those who have sensitive skin or conditions that trigger skin irritation, such as eczema.

Hypoallergenic means that a material has a lower chance of triggering allergic reactions. These kinds of materials or fabrics have few allergens—or none at all.

What types of allergens can cause skin reactions? Some of the more common allergens found in traditional fabrics include:

• Formaldehyde resins

• Certain dyes, such as azo dyes

• Paraphenylenediamine (PPD)

• Flame retardants

• Latex

• Cobalt

• Chrome

• Rubber accelerators

Even metal fasteners can cause fabric allergies.

But Blissy's 100% mulberry silk stands out as a hypoallergenic alternative to cotton, polyester, and other fabrics. It’s a natural material that doesn’t contain allergy-causing substances. Silk can help reduce common allergy symptoms such as sneezing and itching by providing a barrier against allergens.

Benefits of Silk for Sensitive Skin

Silk is a natural protein fiber renowned for its hypoallergenic properties, making it an excellent choice for individuals with sensitive skin. Silk pillowcases, in particular, offer a gentle and soothing sleeping surface that can help reduce skin irritation.

The smooth and tightly woven fibers of silk minimize friction, preventing irritation and making it ideal for those with conditions like dermatitis.

Additionally, silk’s natural breathability helps regulate body temperature and prevent moisture buildup, further reducing the risk of skin irritation. For people with sensitive skin, silk pillowcases provide a luxurious and skin-friendly option.

How Silk Compares to Other Fabrics

Blissy silk stands out from other fabrics due to its natural hypoallergenic properties. Unlike synthetic materials, silk is less likely to trigger allergic reactions and irritate sensitive skin. For instance, cotton can be a common allergen, and polyester is prone to pilling, which can cause friction and irritation.

In contrast, silk is a natural protein fiber that is gentle on the skin and helps prevent allergic reactions. When choosing silk bedding, opt for high-quality, 100% silk products to fully benefit from this natural fiber’s hypoallergenic properties.

What Science Has to Say About Blissy Silk Pillowcase

It's easy enough for companies to claim that their products are "safe for skin" or "allergy tested"—but how true are those claims? At Blissy, we're able to make these claims with full confidence thanks to clinically proven results.

Princeton Consumer Research Corp. recently conducted a study aimed at testing whether our 100% mulberry silk is naturally hypoallergenic. Here's how it was done and what the results showed.

Clinical study details on silk fibers

This study involved having 108 participants wear small patches of Blissy Silk Pillowcase material on their skin. About half of these participants self-reported having sensitive skin. All participants did the following:

• Wore a total of nine patches for 3 weeks

• Did not wear patches at all for a 2-week rest period

• Wore a final challenge patch for 48 hours after the rest period

• Had final readings made at 1 hour and 48 hours after removing the final patch

All had their skin monitored throughout the study to check for any signs of skin irritation or allergic reactions.

Clinical study results

So, is Blissy's silk hypoallergenic? Yes! The study found that the pillowcase patch didn't cause any visible allergic reactions or skin irritation—even in those with sensitive skin.

Based on these findings, researchers concluded that Blissy silk has a low potential for sensitization and irritation. This supports the claims that Blissy pillowcases do indeed have hypoallergenic properties and are safe for use on sensitive skin.

These results also substantiate claims, such as Blissy silk pillowcases are "clinically tested," "dermatologically tested," "dermatologist approved," and "clinically proven."

Why Blissy Silk Stands Out for Sensitive Skin

At Blissy, we use grade 6a 100% pure mulberry silk (highest quality available) for pillowcases and other products. How does this material differ from other fabrics, such as satin, cotton, and cheaper silk brands you might find on Amazon?

Other fabrics haven't been certified as hypoallergenic materials—but our mulberry silk has been clinically proven to have these properties.

That's not the only benefit our silk products offer, though. Unlike other materials, Blissy's mulberry silk also provides the following skin-friendly benefits:

• Natural resistance to dust mites

• Moisture-wicking to help you stay dry

• Temperature regulation to help you feel comfortable throughout the night

Our mulberry silk is also safe for your pores. Silk fiber won't clog your pores and trigger acne. In fact, a recent clinical study found that Blissy silk is non-comedogenic—meaning it didn't cause clogged pores, even in people prone to breakouts. (Princeton Consumer Research Corp., 2024)

These results show that our silk is safe for all skin types, making it the perfect product choice for anyone.

Choosing the Right Silk Pillowcase

Selecting the right silk pillowcase is crucial for individuals with sensitive skin or allergies. Look for pillowcases made from 100% mulberry silk, the highest quality and most hypoallergenic type of silk. Pay attention to the momme weight and weave of the fabric, as a tighter weave can help prevent dust mites and other allergens from penetrating the material.

Also choose a silk pillowcase designed specifically for sensitive skin, avoiding products with dyes or treatments that could cause irritation. By selecting the right silk pillowcase, you can enjoy a comfortable and allergy-free sleep experience.

Caring for Hypoallergenic Silk Pillowcases

Proper care is essential to maintain the hypoallergenic properties of Blissy Silk Pillowcases. To wash your silk pillowcases, use a mild pH neutral detergent (like Blissy Wash) and cold water, and avoid machine drying or ironing, as these can damage the delicate fibers.

Instead, dry your silk pillowcases naturally, away from direct sunlight, to prevent fading or discoloration. Regular washing and maintenance can help prevent the buildup of dust mites and other allergens, ensuring that your silk pillowcase remains hypoallergenic and gentle on your skin.

By following these care tips, you can enjoy the luxurious benefits of silk pillowcases for years to come.

What Other Experts Have to Say About Blissy Silk

While the recent PCR Corp. study showed that Blissy silk is a hypoallergenic fabric, it's helpful to hear from other experts. Below, we'll take a look at comments that two dermatologists have made about Blissy products.

Dr. Pooya Beigi

In a recent podcast interview, dermatologist Dr. Pooya Beigi talked about contact dermatitis and the importance of using the right kind of pillowcase for these allergy sufferers. He explained that "contact dermatitis happens when a patient is exposed or would be in contact with a material or a chemical or something which he or she is allergic to."

Dr. Beigi explained that some fabrics absorb moisture and other substances, like chemicals from makeup, potentially triggering contact dermatitis symptoms. When asked if patients have reactions to certain materials over others, he said that they do. So it is important to choose the right fabric for your skin and silk is always a safe choice.

Dr. Jennifer Ahdout

In a Blissy blog post about making your skin look younger, dermatologist Dr. Jennifer Ahdout had this to say:

"The Blissy Silk Pillowcase has some antibacterial properties. It also reduces the amount of friction between the skin and the pillow surface while someone is sleeping. It also can help to lock moisture in the skin and keep the skin hydrated. So these are just a few of the ways it can help our skin."'

In a blog post on beauty sleep, Dr. Ahdout gave this answer when asked if silk is a more hydrating fabric than cotton:

"The answer is yes. Indeed, silk can help hold moisture much better than cotton can. And so it is a more hydrating fabric."

What Customers Have to Say About Blissy Products

"Within weeks, my skin had cleared up."

"Blissy really really helped my skin a lot."
