It's a modern take on micro-needling in a bottle. Reedle Shot 100 contains microspicule "needles" – they're designed to gently exfoliate your skin, encourage renewal, and allow for better absorption of the active ingredients. You may feel a slight tingling sensation upon application, but don't be alarmed, it's part of the process. Your skin will feel smoother, tighter, and subtly luminous by morning. Avoid pairing it with acids or retinoids on the same day.
