color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eNo. The serum goes onto the skin rather than into the pen, so it is not tied to a model or to a tip type. It is used the same way whichever Dr. Pen microneedling pen you already have, and it does not change which cartridges that pen takes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eCan I use this serum without a microneedling pen?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eYes. Pressed into cleansed skin it is a hydrating step on its own. What the pen adds is a route past the skin's outer layer, which is why the two are normally used together rather than the serum being kept for needling days only.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eIs one box enough to start with?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eYes, and the listing is set up so a single box is a complete purchase. Starting with one settles whether you like how it sits under a pen; taking more boxes changes how many are on the shelf, not what is in each one.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eThe serum is sterile — does that matter for needling?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eIt is the reason each dose is sealed separately. Needling opens the skin, so anything applied during a session should be free of the contamination a shared, repeatedly opened bottle can pick up. A single sealed unit is opened once, for one session, and then discarded.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eCan I keep a part-used dose for the next session?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eNo. Each single-dose unit is used once — once it is open there is no seal left to protect what remains. Use it through in the session it was opened for and discard it, rather than carrying it over to the next one.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eDo the single-dose units have to be kept in the fridge?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eNo. Because each unit is sealed until it is opened, cool, dry storage out of direct sunlight is enough, and that is how unopened units are meant to be held until you work through them.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #E5E5E5; border-radius: 8px; margin-bottom: 12px; background: #F5FAF8;\" open=\"\"\u003e\n\u003csummary style=\"padding: 14px 18px; font-weight: bold; font-size: 15px; color: #000000; cursor: pointer;\"\u003eHow quickly does a box reach me in the US?\u003c\/summary\u003e\n\u003cdiv style=\"padding: 12px 18px 16px; color: #555555; font-size: 14px; line-height: 1.7;\"\u003e\n\u003cp\u003eThis box is held in our US warehouse, so it is sent to US addresses on a domestic service with no international transit and no customs delay at the border.
