How should I incorporate these patches into my existing skincare routine, especially if I already use products with retinoids or acids? — Gift set "5 Senses" consisting of five 8 g hydrogel eye patches, DIZAO.

Think of these patches as an occasional treatment step, not a replacement for your daily eye cream or serum. You can use them after cleansing and toning, on clean, dry skin under the eyes. Apply the patch, leave it on for the recommended time (usually 10-20 minutes), then remove. You can gently pat in any remaining essence. Since they contain retinol, which is a well-known cosmetic active, extra caution is needed. If your skin is very reactive or you are already using strong prescription retinoids, retinol serums, or exfoliating acids (like AHAs/BHAs) in your routine, the combined effect could lead to irritation. In such cases, it's wise to patch test first, start with shorter application times, and use them less frequently—perhaps once a week initially. Always stop use if any redness, stinging, or irritation appears. For those with sensitive skin or specific conditions, consulting a dermatologist before incorporating new active ingredients is a good practice.
