The A1 pen is sold separately.\u003c\/p\u003e\n\u003ch3\u003eWhich cartridge options can I choose?\u003c\/h3\u003e\n\u003cp\u003eThe selectable options are 9, 12, 24, 36 and 42 pins, plus 3D Nano, 5D Nano and Round Nano. The reference chart includes other examples that are not selectable on this listing.\u003c\/p\u003e\n\u003ch3\u003eWill these fit every Dr. Pen model?\u003c\/h3\u003e\n\u003cp\u003eNo universal fit is claimed. This listing specifies A1. Check the model and connector before ordering rather than choosing by appearance alone.\u003c\/p\u003e\n\u003ch3\u003eHow are the nano options different?\u003c\/h3\u003e\n\u003cp\u003eThe product photos show a smaller square contact face for 3D Nano, a larger square face for 5D Nano, and a circular face for Round Nano. These names describe tip options, not needle depths or guaranteed results.\u003c\/p\u003e\n\u003ch3\u003eWhat needle size should I use?\u003c\/h3\u003e\n\u003cp\u003ePin count and needle depth are different. The selected option determines the head configuration, while the compatible pen controls needle projection. A trained practitioner should select settings for the individual procedure.\u003c\/p\u003e\n\u003ch3\u003eWhat is an A1 microneedling pen used for?\u003c\/h3\u003e\n\u003cp\u003eIt is a powered device used in skincare procedures focused on concerns such as visible fine lines, uneven texture, pores, scars, stretch marks and pigmentation. This listing supplies replacement heads, not the device, and does not promise correction of those concerns.\u003c\/p\u003e\n\u003ch3\u003eHow often should I use the pen?\u003c\/h3\u003e\n\u003cp\u003eThere is no single schedule for every person or procedure. Follow the device instructions and a qualified practitioner's guidance rather than applying a fixed interval to all skin conditions.\u003c\/p\u003e\n\u003ch3\u003eCan I wash and reuse a cartridge?\u003c\/h3\u003e\n\u003cp\u003eNo. These are disposable cartridges. Use a fresh cartridge for each person and each session.\u003c\/p\u003e\n\u003ch3\u003eHow do I check an authentication code?\u003c\/h3\u003e\n\u003cp\u003eIf the supplied packaging has an authentication label, scratch to reveal the full QR code and number, then follow the verification instructions on that packaging. A product photo alone does not verify authenticity.\u003c\/p\u003e\n\u003ch3\u003eDo the different tips guarantee specific skin or hair results?\u003c\/h3\u003e\n\u003cp\u003eNo. Pin count does not guarantee scar reduction, acne clearing, skin lightening or eyelash and eyebrow growth. Nano tips are not a promise of painless use or a substitute for professional assessment.\u003c\/p\u003e","brand":"iTech Aesthetics","offers":[{"title":"9PIN","offer_id":48991379357833,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"12Pin","offer_id":48991379390601,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"24Pin","offer_id":48991379423369,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"36Pin","offer_id":48991379456137,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"42Pin","offer_id":48991379488905,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"3D Nano","offer_id":48991379521673,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"5D Nano","offer_id":48991379554441,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true},{"title":"Round Nano","offer_id":48991379587209,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/9017\/7417\/files\/1_6c3a6e44-8493-4a15-82c3-086a8f460d71.jpg?v=1794467899","url":"https:\/\/itechaesthetics.com\/de\/products\/dr-pen-a1-cartridges","provider":"Guangzhou Itech Aesthetics Co.,Ltd","version":"1.0","type":"link"}
