Numbuzin No.5 Vitamin Serum 30ml

Visible improvements in dark spots and skin tone can typically be observed within two to three weeks of consistent daily use.

It is generally compatible with most skincare, but caution is advised when layering with other strong actives like AHAs/BHAs or retinoids. Patch testing is recommended.

While formulated with barrier-supporting ingredients, it contains potent actives. Sensitive skin types should perform a patch test first and may need to use it less frequently.

It can be used both morning and night. For daytime use, always follow with sunscreen.

The serum features a blend of glutathione, tranexamic acid, and niacinamide, known for their efficacy in fading hyperpigmentation.

Store in a cool, dry place away from direct sunlight. Keep the cap tightly closed to prevent oxidation.

The Numbuzin No.5 Vitamin Serum comes in a 30ml bottle.

This can be a normal sensation due to the active ingredients. If it persists or becomes uncomfortable, reduce frequency of use or try applying on alternate days. Always patch-test first.

Ensure you are storing the serum correctly, away from light and heat. Consistent daily application is key. Consider if other products in your routine might be interfering.

Discontinue use immediately. This may indicate a sensitivity to one of the active ingredients. Consult the ingredient list and consider a more gentle serum.

Ensure you are using the correct amount (2-3 drops). Pat the serum into the skin rather than rubbing, and allow it to absorb fully before applying moisturizer.
