NUMBUZIN NO.5 Glutathione C Facial Spa Cleanser 300ml Cleansing Oil

✅ What it is

• It’s a cleansing oil formulated with antioxidant/brightening actives — labelled as “Glutathione C” (i.e., glutathione + vitamin C) — together with botanical oils. 

• Volume: 300 ml for the version you asked about. 

• The brand describes it as a “spa cleansing” oil: it melts makeup (even heavier or waterproof), opens pores/melts sebum via a warm-oil massage effect, then emulsifies with water. 

• Key ingredients include: Jojoba Seed Oil, Olive Fruit Oil, Sunflower Seed Oil (around ~30,003 ppm in the “DeepTox Oil” complex) plus glutathione, vitamin C (ascorbic acid), niacinamide, Hippophae Rhamnoides (sea-buckthorn) oil. 

• Aromatic oils (lavender, lemon peel, mandarin orange peel, cedarwood, rosemary) to give a relaxing aroma/spa feeling.

🧴 How to use it

• Use as the first cleanse of your routine (especially if you wear makeup/sunscreen). Because it’s an oil cleanser:

  1. Pump 2-3 times onto dry hands + warm between palms. 

  2. Apply to dry face & massage to dissolve makeup/impurities. 

  3. Add a little water to emulsify (the oil will turn milky) and then rinse thoroughly with lukewarm water. 

• Follow with your second cleanse (if you do double cleansing), then proceed with toner/serum/moisturizer.

• Because it has fragrance/aromatics and is oil-based, if you have oily skin you might choose a lighter second cleanse.

• Patch test if you have very sensitive/reactive skin (see “things to watch” below).

🎯 What skin types & concerns it’s good for

Good for:

• Those who wear makeup/sunscreen daily: The oil base is good at dissolving waterproof formulas & tinted products.

• Dull, uneven skin tone: With glutathione + vitamin C + niacinamide, meant to help with brightening and fading the look of oxidised sebum/darkened pores. EmpressKorea+1

• Normal to combination skin, or even those with dry skin (since the oil base also has nourishing oils).

• People who enjoy a spa-style skincare ritual: the warm massage + aromatic oils enhance the experience.

Less ideal for:

• Extremely oily, acne-prone skin (especially if you find oil cleansers make you break out) — though many oil cleansers can work if followed by a gel/foam second cleanser, you’ll want to monitor.

• Very sensitive skin that reacts to fragrance or essential oils: the presence of lemon peel oil, aromatic oils etc may cause irritation for some.

• People who prefer fragrance-free minimal formulations.

From user feedback:

“It brightened my skin a bit … but the fragrance I couldn’t deal with.” Reddit
“I had the worst purging because of this, my skin was clearing up before I used it and after 2 months I am having the worst acne I have had EVER!!!” Reddit
So individual responses vary.

⚠️ Things to watch / potential downsides

• Fragrance/aromatic oils: If your skin is sensitive to fragrance/essential oils, this could cause redness, irritation or closed comedones.

• Because it's oil-rich and has aromatic components, if you already have oily skin and tend to break out, you’ll want to ensure you rinse thoroughly and follow with appropriate cleansing and lightweight products.

• “Brightening” claims: While glutathione & vitamin C are good antioxidants, the real-world impact on established deep pigmentation can be modest. It may work better for “evening tone” rather than dramatic reversal of long-standing marks. (Many user reports say similar.)

• Product authenticity & storage: If importing to Pakistan or through international sellers, check for genuine packaging, expiry date, and storage conditions (since oils + vitamins can degrade with heat/light).

• Price & availability: Because it's Korean import, local mark-up + shipping/availability may be issues.

💡 Is it good for you in Pakistan (Karachi etc)?

Given you’re in Karachi (hot/humid environment at times) here’s how this cleanser fits:

• Since humidity and pollution are factors, a good first cleanse like this can help remove sunscreen/makeup/pollutants — that’s a plus.

• If your skin leans oily due to heat/humidity, I’d suggest: use this oil cleanser at night (when you’ve worn more sunscreen/makeup) and follow with a gentle water-based second cleanser. For daytime or lighter cleanses, you might use a gel cleanser instead.

• If you live in an air‐conditioned environment (drying indoor air) or your skin tends toward dryness (especially after using active serums), this oil cleanser may help maintain barrier hydration.

• Make sure to use a good broad‐spectrum sunscreen during the day (brightening actives work best when sun protection is solid).

• Because of local import/export, ensure you buy from a trusted retailer in Pakistan (to ensure authenticity) and check for expiry date.

📝 Summary / My Take

If I were to summarise:
Pros: Luxurious oil-cleanser experience, excellent for removing heavy makeup/sunscreen/pollution, contains brightening/antioxidant actives, spa-style feel.
Cons: Might be too rich/heavy for some very oily or acne-prone skin; contains fragrance/aromatics; brightening effects may be modest for deep pigmentation; imported cost might be higher.

Verdict: If your skin type and lifestyle match (you use sunscreen/makeup, you have some concerns around dullness or uneven tone, you enjoy a nicer skincare experience), this cleanser is a good choice. If your skin is ultra oily/acne-prone and you prefer minimal formulas, you might choose a lighter oil cleanser or alternate it.
