It is made for microneedling sessions with an at-home pen, and it works on its own as an everyday hydrating serum.\u003c\/p\u003e\n\u003ch3 style=\"font-weight: bold;\"\u003eWhy 4D HYALURONIC ACID\u003c\/h3\u003e\n\u003cp\u003eA box holds ten sealed ampoules of clear liquid serum. There is no powder and no second solution to add, so nothing has to be mixed or activated before the first use. Ampoules are opened one at a time and each one is used once, which leaves the rest of the box sealed until it is needed.\u003c\/p\u003e\n\u003cp\u003eThe serum is formulated for dry and sensitive skin and is applied over the surface of the face. \u003c\/p\u003e\n\u003ch3 style=\"font-weight: bold;\"\u003eHow it is used\u003c\/h3\u003e\n\u003cp\u003eOn its own it is a hydrating step.

The head is twisted or snapped off in a single movement and the serum is dispensed straight from the ampoule, so no syringe and no separate applicator is needed. Once it is open, the ampoule is finished — it is not resealed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #eaf6ff; border: 1px solid #D6EBFB; border-radius: 8px; padding: 14px 16px; margin: 10px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0 0 6px 0;\"\u003e\u003cstrong\u003eWhy ten small ampoules instead of one bottle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"color: #4b5563; margin: 0;\"\u003eA sealed ampoule is opened once and used once, so each application starts from its own closed unit rather than from a container that has already been opened repeatedly. A bottle is opened every time it is used, and the ampoule format removes that repeated opening step altogether. The ten-ampoule pack also means the rest of the box stays sealed until you reach it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #eaf6ff; border: 1px solid #D6EBFB; border-radius: 8px; padding: 14px 16px; margin: 10px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0 0 6px 0;\"\u003e\u003cstrong\u003eWhich step does the serum belong to when I use a microneedling pen?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"color: #4b5563; margin: 0;\"\u003eIt sits at the microneedling step itself. The serum is applied to the treatment area first and the pen is then passed over that same area, and the liquid stays on the skin afterwards rather than being removed. On a day with no pen, the same ampoule is simply applied to clean skin as a hydrating step.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #eaf6ff; border: 1px solid #D6EBFB; border-radius: 8px; padding: 14px 16px; margin: 10px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0 0 6px 0;\"\u003e\u003cstrong\u003eShould it be rinsed off after a microneedling session?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"color: #4b5563; margin: 0;\"\u003eNo — there is no rinse step. The serum is left on the skin, and anything still sitting on the surface can be pressed in with clean fingertips. A moisturiser can go over it if that is part of your usual routine.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #eaf6ff; border: 1px solid #D6EBFB; border-radius: 8px; padding: 14px 16px; margin: 10px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0 0 6px 0;\"\u003e\u003cstrong\u003eDoes it need to be kept cold?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"color: #4b5563; margin: 0;\"\u003eNo. Sealed ampoules are kept at room temperature until they are used, and freezing is not part of the pack instructions. An ampoule that has been opened is not put back for later — it is used once and discarded.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #eaf6ff; border: 1px solid #D6EBFB; border-radius: 8px; padding: 14px 16px; margin: 10px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0 0 6px 0;\"\u003e\u003cstrong\u003eDo I cleanse first, and does the skin need to be completely dry?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"color: #4b5563; margin: 0;\"\u003eCleanse first and let the skin dry fully. A damp surface changes how evenly the serum spreads, so serum applied over it does not sit where it was meant to. Open the ampoule only when the skin is ready, so the application is not spent on a surface that has not been prepared.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3 style=\"font-weight: bold;\"\u003eWhat it pairs with\u003c\/h3\u003e\n\u003cdiv style=\"display: flex; justify-content: center; gap: 12px; margin: 18px 0;\"\u003e\n\u003ca href=\"https:\/\/www.pdothreadstore.com\/products\/2024-newest-dr-pen-ultima-m8s-professional-microneedling-pen-6-speeds-led-screen-easy-use\" style=\"flex: 0 1 200px; max-width: 200px; text-decoration: none; background-color: #123e7c; border-radius: 6px; padding: 8px; display: block; text-align: center;\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/1837\/1248\/files\/1_b672584d-52a8-4a21-915c-d677211184bb.jpg?v=1739500248\u0026amp;width=440\" alt=\"Dr. Pen Ultima M8S microneedling pen\" style=\"width: 100%; height: 150px; object-fit: contain; background-color: #ffffff; border-radius: 6px; display: block;\"\u003e\u003cstrong style=\"display: block; color: #ffffff; font-size: 13px; margin-top: 8px;\"\u003eDr. Pen M8S\u003c\/strong\u003e\u003c\/a\u003e \u003ca href=\"https:\/\/www.pdothreadstore.com\/products\/popular-dr-pen-a10-wireless-auto-microneedling-therapy-pen\" style=\"flex: 0 1 200px; max-width: 200px; text-decoration: none; background-color: #123e7c; border-radius: 6px; padding: 8px; display: block; text-align: center;\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/1837\/1248\/files\/8_c5c5832e-616a-4211-968f-e745ef6207ce.jpg?v=1739500494\u0026amp;width=440\" alt=\"Dr. Pen A10 wireless auto microneedling pen\" style=\"width: 100%; height: 150px; object-fit: contain; background-color: #ffffff; border-radius: 6px; display: block;\"\u003e\u003cstrong style=\"display: block; color: #ffffff; font-size: 13px; margin-top: 8px;\"\u003eDr. Pen A10\u003c\/strong\u003e\u003c\/a\u003e \u003ca href=\"https:\/\/www.pdothreadstore.com\/products\/2026-new-dr-pen-m9\" style=\"flex: 0 1 200px; max-width: 200px; text-decoration: none; background-color: #123e7c; border-radius: 6px; padding: 8px; display: block; text-align: center;\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/1837\/1248\/files\/M9.120.jpg?v=1772788161\u0026amp;width=440\" alt=\"Dr. Pen M9 microneedling pen\" style=\"width: 100%; height: 150px; object-fit: contain; background-color: #ffffff; border-radius: 6px; display: block;\"\u003e\u003cstrong style=\"display: block; color: #ffffff; font-size: 13px; margin-top: 8px;\"\u003eDr. Pen M9\u003c\/strong\u003e\u003c\/a\u003e\n\u003c\/div\u003e","brand":"Boujeela","offers":[{"title":"2 Boxes","offer_id":43843872653488,"sku":"","price":69.3,"currency_code":"USD","in_stock":true},{"title":"5 Boxes","offer_id":43843872719024,"sku":"","price":137.5,"currency_code":"USD","in_stock":true},{"title":"10 Boxes","offer_id":43843872751792,"sku":"","price":218.9,"currency_code":"USD","in_stock":true},{"title":"20 Boxes","offer_id":45615727706288,"sku":null,"price":350.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/1837\/1248\/files\/A0e0bd05d120c483caee6e9fbb30994daf.jpg?v=1791859378","url":"https:\/\/www.pdothreadstore.com\/products\/sterile-pure-hyaluronic-acid-serum-for-microneedling","provider":"Auro Technology","version":"1.0","type":"link"}
