The clear, gentle formula sinks in fast, letting you get on with your day or night without waiting around.

Kind Ingredients That Work Hard

NUMBUZIN No.5 is made with ingredients that both calm and help your skin. Niacinamide helps even out skin tone and makes your skin stronger. Panthenol soothes and locks in moisture, while lingonberry fruit extract helps protect your skin from daily stress.

  • Glutathione: A helper that brightens skin and evens out tone

How This Serum Helps Your Skin

Your skin faces a lot each day – sun, stress, lack of sleep. This serum steps in to help with the most common skin wishes. It brightens dull skin, helps fade dark spots, and adds a fresh glow to your face. The blend of vitamins helps protect your skin from daily wear and tear.

If your skin feels dry, this serum adds the right amount of moisture. If it feels oily in spots, the light texture won't make things worse. And if your skin tends to get red or upset, the gentle mix of ingredients helps calm things down. It's like a daily reset button for your face, bringing balance back to all skin types.

Easy Steps to Glowing Skin

Using this serum is simple and fits into any skincare routine. Start with clean skin – wash your face and pat it dry. If you use a toner, apply that first and let it sink in.

  • Put 3-5 drops of serum in your palm
  • Gently spread it over your face and neck
  • Pat lightly with fingertips to help it sink in
  • Follow with your moisturizer
  • Add sunscreen in the morning to protect your skin

You can use this serum twice a day – morning and night. In the morning, it helps shield your skin from the day ahead. At night, it works while you sleep to help your skin recover and refresh.

Not sure a new serum would agree with sensitive skin

I've tried the serum I wasn't sure i was going to like it bc i have combo/acne/sensitive skin but wow it's been a while since i used a serum and i noticed that after about a month my mom was asking me how my skin was suddenly glowing?? the first time i put it on my skin actually tingled so much but i kept using it only in the mornings and now i have zero reaction to it day/night and i already ordered a second bottle which is pretty rare for me LOL

A tranexamic acid serum that left skin irritated

I have tried Cos de Baha tranexamic and niacinamide: it left my skin quite irritated. I have also tried Numbuzin No. 5+ concentrated serum and it doesn't irritate my skin. I can use Numbuzin while using tret but I can't say the same for Cos de Baha.

A concentrated step towards a fresher-looking glow.
