When in my routine should I apply it, and what should I use afterward?

Apply it in the evening after cleansing, as the first skincare step. Avoid the eye and mouth areas, gently rub and press, then finish with a water-based moisturizer.

Do I rinse the serum off after applying it?

No. Leave the serum on, then complete your routine with a water-based moisturizer.

Can a beginner apply it only to areas with visible pores or uneven texture?

Yes. After cleansing, prepare your skin with a hydrating toner, apply the serum only to the areas you want to target, then gently rub and press before finishing with a water-based moisturizer.

What does the spicule formula feel like on the skin?

Expect a noticeable tingling or prickly sensation that may linger for some time. Redness, itching or a feeling of warmth may also occur.

What guidance does MEDICUBE give for sensitive skin?

Sensitive skin is included among the listed skin-type fits, but MEDICUBE advises patch-testing first and adjusting the amount and frequency to your individual sensitivity.

Should a beginner use this serum with an AGE-R device?

No. MEDICUBE does not recommend device pairing if you are unfamiliar with spicule skincare. For experienced users, application after the AGE-R Booster Pro's Air Shot Mode is presented as an optional method.

What happens to the spicules after the product is left on?

The hydrolyzed-sponge spicules are designed to shed naturally with dead skin over several days rather than being absorbed into the body. Leave the serum on instead of rinsing it away.
