It is suitable for face, body, and scalp use at home or in a professional salon or spa.\u003c\/p\u003e\n\u003ch3\u003eDoes the Dr Pen A11 have automatic serum infusion?\u003c\/h3\u003e\n\u003cp\u003eNo. The A11 is a dry microneedling pen — it does not have a built-in serum reservoir or automatic serum infusion function. Apply serum to the skin before or after treatment. If you need automatic serum infusion, the Dr Pen H3 or H-series hydra pens are designed for that purpose.\u003c\/p\u003e\n\u003ch3\u003eWhat cartridges are compatible with the Dr Pen A11?\u003c\/h3\u003e\n\u003cp\u003eThe A11 uses Dr Pen A11 replacement cartridges in 12, 18, 24, 36, 42 pin and nano configurations. These are not interchangeable with H-series (H3\/H5\/H6) hydra cartridges. Cartridges are sold separately and are single-use only.\u003c\/p\u003e\n\u003ch3\u003eHow deep should the needle be set for facial treatments?\u003c\/h3\u003e\n\u003cp\u003eFor general facial rejuvenation at home, start at a shallow depth and increase gradually based on skin tolerance. Deeper settings are typically used for scar revision or body treatments by professionals. Always follow the user manual guidelines.\u003c\/p\u003e\n\u003ch3\u003eHow often can I use the Dr Pen A11?\u003c\/h3\u003e\n\u003cp\u003eFor home use, once every 2–4 weeks allows adequate skin recovery. Professional clinic use may follow a more intensive schedule depending on treatment goals and skin condition.\u003c\/p\u003e\n\u003ch3\u003eCan the Dr Pen A11 be used on the scalp for hair loss?\u003c\/h3\u003e\n\u003cp\u003eYes. The A11 can be used on the scalp to support hair follicle stimulation and blood circulation when used alongside appropriate topical treatments. Use a dedicated scalp cartridge and set needle depth appropriately for scalp applications.\u003c\/p\u003e","brand":"iTech Aesthetics","offers":[{"title":"US","offer_id":48010571415689,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false},{"title":"EU","offer_id":48010571448457,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false},{"title":"UK","offer_id":48010571481225,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false},{"title":"AU","offer_id":48010571513993,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false},{"title":"KR","offer_id":48010571546761,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/9017\/7417\/files\/1_2183c544-d4e3-4e4e-9bac-57f27e4854bb.jpg?v=1787546776","url":"https:\/\/itechaesthetics.com\/es-jp\/products\/dr-pen-a11-hydra-microneedling-pen-adjustable-depth-derma-pen","provider":"Guangzhou Itech Aesthetics Co.,Ltd","version":"1.0","type":"link"}
