How do I apply these lip patches, and how often should I use them?

Hydrogel patches of this type are applied to clean, dry skin — remove makeup and any lip balm or cream first, since an oily film can stop the hydrogel from adhering closely. Then:

1. Take the patch out of the sachet and place it over the mouth area so it covers the whole perioral zone — the upper lip lines, the lower lip line and the corners of the mouth. Smooth it gently so it sits flat without air pockets.
2. Relax the face while it is on. The patch works best when the area isn't moving, so avoid talking, eating or drinking during wear.
3. Leave it on for the time indicated on the packaging, then peel it off and pat any remaining serum into the skin instead of rinsing it away.

Good moments to use it are before applying makeup (fine lines around the lips are less likely to catch lipstick when the skin is well hydrated), before an event, or whenever the lip contour feels dry and looks creased. The effect is cosmetic and temporary, so regular use — for example as part of weekly facial care — is what helps maintain a softer-looking result over time. The patch is single-use; store unopened sachets away from heat so the hydrogel doesn't dry out.
