This mask is intended for adult skin, especially when the first expression lines are becoming noticeable or when the skin needs a temporary hydrated, refreshed look. However, if your skin is very reactive, currently irritated, or prone to discomfort with fragranced or peptide-containing products, it is better to test before applying it to the whole face.
For a simple patch test, apply a small amount of the serum from the sachet to the inner forearm and wait to see whether redness, itching, stinging or unusual discomfort appears. A patch test cannot guarantee that your face will react the same way, but it can help identify obvious intolerance before you use the full mask.
Avoid placing the sheet too close to the eyes, and do not apply it over broken, freshly exfoliated or visibly irritated skin. If you feel strong stinging, burning or persistent discomfort during use, remove the mask and rinse the area with water. If you are pregnant, breastfeeding, under specialist skin care, or unsure whether peptide or fragranced cosmetics suit you, ask a qualified professional before use.
