OverviewPrevious page Next page Previous page Next page Can I replace the tube only when I finish it? Yes, you can remove the tube and replace it with a new one by opening the cap of the HEVEBLUE Black Yuja Bean Lifting Eye Cream applicator. Is it clinically tested and hypoallergenic? Yes, it has been clinically tested by the Korea Institute of Dermatological Sciences for eye wrinkle and laugh line alleviation. It is proven hypoallergenic with a 0.00 irritation index, ensuring it is safe for sensitive skin. Can I use it on areas other than my eyes, and when should I use it? Yes, you can use it on areas needing anti-wrinkle care and massage, like laugh lines and between the brows. Use it in the morning and evening as the final step of your skincare routine. How long can I use it and how do I store it? If used for 1 minute per session, it lasts up to 180 uses, though longer sessions may reduce this. After use, wipe it with a wet tissue or alcohol swab and cap it for hygiene. Avoid water contact, as it may cause damage and void refunds or exchanges. Can I change just the battery? Yes, you can. Device performance may drop 2.5%–5% after 3–6 months, so regular battery replacement is recommended. Separate the applicator, remove the silver tip, replace the battery, and reinsert the tip. Compatible with L115F, L1154, LR44, AG13, A76, V13GA.
