Formula makes pillowcases and sleep masks from 100% pure premium mulberry silk, with skincare built into the fabric. This guide explains the Hyaluron silk pillowcase and the Anti-Acne silk pillowcase, who each one is for, and what to put in your bed alongside them. Think of it as the easiest beauty step you can do while asleep.
Formula Silk Pillowcases and Sleep Masks: Hyaluronic and Anti-Acne Silk, Explained
Formula silk pillowcases and sleep masks: what they are
Silk pillowcases have been a beauty-editor staple for years, but Formula adds a twist. The brand says its pillowcases are made from 100% pure premium mulberry silk, and its tagline is "skincare in every thread". The idea is that a pillowcase is the one thing your face touches for roughly eight hours a night, so it might as well do something. Formula puts it as "8 hours of effortless skincare, every night".
There are two main versions. The Hyaluron Silk Pillowcase is infused with hyaluronic acid and designed for dry and dehydrated skin. The Anti-Acne Silk Pillowcase is infused with silver ions, which the brand says have antibacterial properties, and it is designed for acne-prone skin. Formula also reports that 76% of customers saw a visible beauty benefit, a figure that comes from the brand's own survey, so treat it as a marketing claim and not a study.
I like the pitch because it is easy to understand. Silk is smoother than cotton, so there is less tug on skin and hair, and the treatment is already in the fabric. This edit lines up the Formula pieces and a few silk basics from Lunya for the rest of the bed.
Hyaluronic and anti-acne silk, explained
Choosing between the two Formula pillowcases comes down to your skin. If your face feels tight by morning, go for the Hyaluron Silk Pillowcase, which is the one infused with hyaluronic acid for dry and dehydrated skin. If you break out and want a cleaner surface to sleep on, the Anti-Acne Silk Pillowcase is the answer, thanks to its silver ion infusion. The Hyaluron Silk Sleep Mask is the travel-friendly add-on, so you get the same silk against your eyes on a plane or in a bright hotel room.
The Power Pair and The Hydration Duo are the two bundles, useful if you want a second pillowcase to rotate while the first is in the wash. Lunya fills out the rest of this grid with its Washable Silk Sleep Mask, its Good in Bed Pillowcase and The Quintessential Pillowcase Set, which are good comparisons if you want a washable silk without the skincare infusion.
Care tip: wash silk gently and follow the label on whichever you buy. What I would skip is sleeping on a silk pillowcase with a heavy hair oil on your strands, since it will transfer. Let the hair dry first.
Washable silk sleepwear to match
Once the pillowcase is sorted, the rest of the bedtime outfit is an easy upgrade. Lunya makes washable silk sleepwear, so these pieces are meant to live in a regular wash cycle. The Washable Silk Sleep Shirt Dress is the classic, long enough to feel like a robe and light enough for warm rooms. The Washable Silk Oversized Sleep Tee is the casual, lazy-Sunday pick. The Long Sleeve Pant Set is the full matching version for cooler nights, and the Bias Pant is a separate bottom that works under a favorite tee.
There is a real reason to consider this as a set. Silk regulates temperature well, which is why people who run warm often prefer it to cotton. Pairing a silk pillowcase with silk sleepwear means a smoother surface from head to toe.
The way I would build a bedtime kit: one Formula pillowcase, a sleep mask, and a single sleep set you actually love. What I would skip is buying every color. A calm palette makes a bedroom feel quieter, which is half the point.
