About No.5 Goodbye Blemish Serum

Overview

No.5 Goodbye Blemish Serum is a lightweight serum from Numbuzin, a brand based in Korean. The formula is built mainly around hydration. The ingredient list runs to 39 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Butylene Glycol, Glycerin and Panthenol, humectants that pull water into the upper layers of skin rather than sealing it there.

What the formula does

Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Panthenol and Sodium Hyaluronate.

Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Panthenol, Centella Asiatica Extract and Chamomilla Recutita Flower Extract.

Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Dipotassium Glycyrrhizate, Ascorbyl Glucoside and Ascorbic Acid.

Who it suits

On richness alone it suits Balanced, Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.

What it does not target

The formula contributes little or nothing on cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.

What is not in it

Reading the full list, the formula is no drying alcohol, paraben-free, silicone-free, microplastic-free, sulfate-free and dye-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance and essential oils, worth knowing if your skin reacts to any of them.

Where it fits in a routine

It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.

This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

What to layer it with

Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.

Compatible with

  • Vitamin C (L-ascorbic acid)
  • PHAs (gluconolactone)
  • Azelaic acid
  • Copper peptides
  • Bakuchiol
  • Niacinamide
  • Hyaluronic acid
  • Ceramides
  • Signal peptides
  • Panthenol
  • Sunscreen

Use with caution

  • Benzoyl peroxide

    Best kept to separate routines — one in the morning, one at night, or on alternate days.

  • Retinoids (retinol, retinal)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • AHAs (glycolic, lactic)

    Can be layered, but the combination raises the irritation risk. Go slowly.

  • BHA (salicylic acid)

    Can be layered, but the combination raises the irritation risk. Go slowly.

Where it fits in a routine

Morning Evening
  1. Cleanse
  2. Toning
  3. Treat
  4. Moisturise
  5. Protect

This product is the "Treat" step.

  • Apply to clean, dry skin and give it a minute to absorb before the next layer.
  • Introduce one new treatment at a time so you can identify what is working.

Safety and suitability

Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.

Pregnancy and breastfeeding
Nothing in this formula is on the standard pregnancy-caution list. That is not clearance — ask your doctor about anything you use daily.
Fungal acne (malassezia)
1 ingredient could feed malassezia: Polyglyceryl-10 Laurate. That is about the yeast's food supply, not a prediction that you will break out.
Sensitive and reactive skin
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Recorded ingredient risks
