Can a silk pillowcase prevent the injected product from migrating?

No. No textile can influence the migration of a product injected under the skin — that depends on physiological factors and the injector's technique. A smooth surface only reduces the external mechanical friction the skin experiences during sleep, which remains a separate comfort factor.

How long should I be careful about my sleep position after an injection?

This varies by practitioner and treated area, typically between 24 and 72 hours. This should be confirmed directly by the professional who performed the injection, since it depends on the product used and the area involved.

Why Sleep Position Matters After an Injection

After a hyaluronic acid injection (cheeks, lips, jawline), most practitioners recommend avoiding prolonged pressure on the treated area for 24 to 72 hours, while the product settles into the tissue. Side sleeping, however, exposes part of the face to prolonged contact and repeated friction against the pillow with every nighttime movement.

The Role of Fabric Texture, Regardless of Position

Choosing a pillowcase never replaces a positioning instruction given by an injector. But for the same position, surface texture changes the nature of the contact: a pillowcase with seams, raised patterns or embroidery creates localized friction points with every micro-movement at night, whereas a completely smooth surface distributes contact more evenly across the skin.

      "A relief-free surface does not correct a poor sleep position — it only reduces the intensity of mechanical friction at each point of contact, whatever position is adopted.

Fabric Never Replaces Your Practitioner's Instructions

Choosing a smooth textile is about mechanical comfort during the recovery phase — it is not a medical device, nor a guarantee of results. The positioning, timing and aftercare instructions given by your practitioner remain the absolute reference to follow.
