Numbuzin - No.2 Goodbye Redness Derma Tone Up 50ml

Numbuzin — No.2 Goodbye Redness Derma Tone Up 50 ml

This is a multifunctional tone-up / color correcting cream with added skincare benefits. It is designed to correct redness, even out skin tone, and provide sun protection — all in one step. It acts as a primer, color corrector, and lightweight coverage product, while also caring for sensitive or irritated skin.

It is often marketed as a “3‑in‑1” or “4‑in‑1” formula: tone-up (brightening), redness correction, sun protection (SPF), and skincare care (derma ingredients, soothing botanicals). See listings that call it “3 in 1 product: Offers three different functions at once (Sunscreen SPF50+ PA+++, foundation, and green makeup primer)”

Key Claims & Consumer Benefits

Here are the main claims and benefits as presented by retailers and manufacturers, along with what they suggest for users:

• Redness Neutralizer / Color Correcting
  The cream has a pale green base that helps counteract visible redness. Upon blending, it shifts toward beige to better match skin tone. 
  It “effectively blurs blemishes to produce the perfect canvas for the rest of your makeup routine.” 

• Sun Protection
  It includes SPF 50+ PA+++ to offer broad-spectrum protection against UV rays. 

• Skincare / Soothing / Derma Ingredients
  To support its “derma tone up” branding, it contains botanical and calming extracts intended to reduce irritation and redness (e.g. Centella Asiatica, tea tree leaf, Artemisia, etc.).
  Some listings highlight it is dermatologically tested and claim it’s safe for skin that is sensitive. 

• Lightweight & Brightening Look
  The texture is intended to feel lightweight, non-greasy, and to provide a brightening / fresh look once applied. 
  It is claimed to last all day, providing coverage for redness and acting as a base for makeup.

• Tone Correction + Foundation / Base Use
  Because of its corrective tint and coverage capabilities, it's positioned to be used as a “makeup base” or “primer / tone-up base” before further cosmetics.

Ingredients & Formula Highlights

While I don’t have a verified full ingredient list from the official manufacturer, some sources list key actives and typical components. Below are ingredients that many listings mention, and what they suggest functionally.

Key Functional Ingredients & Their Purposes

• Titanium Dioxide / Zinc Oxide
  Used as physical (mineral) UV filters, helping to deliver the SPF 50+ PA+++ claim. 

• Niacinamide
  A well-known multitasker — brightening, barrier support, anti-inflammatory, helping reduce redness or pigmentation over time.

• Botanical / Soothing Extracts
  Several plant-based extracts are cited in listings:

  • Centella Asiatica (calming, anti-inflammatory) 

  • Tea Tree Leaf Extract (antibacterial, soothing)

  • Artemisia capillaris

  • Houttuynia cordata 

  • Noni extract, Fusidium, U‑Ferment, Oil AOC (as part of “Double Green Complex” in marketing) 

• Moisturizing Agents / Emollients / Silicones
  To give a smooth spread, comfortable wear, and skin-feel, the formula likely includes:

  • Silicones or silicone derivatives (e.g. dimethicone, cyclopentasiloxane) for slip and blendability

  • Glycerin, butylene glycol or similar humectants for hydration

  • Emollients or oils in small amounts for texture and finish

• Color / Pigments & Tone-Up Agents
  Green pigments or corrective tinting agents are added to offset redness. The marketing describes a green base that transforms to beige when blended. 

• Other Supporting/Functional Ingredients
  Ingredients for thickening, stabilizing, preserving the formula (e.g. emulsifiers, silicones, film-formers, stabilizers) are also likely present (though not always disclosed in public listings).

One listing from Kosmetrics gives a long ingredient lineup which includes: madecasoside, polysilsesquioxane, centella asiatica, dimethicone, cyclopentasiloxane, glycerin, tea tree, etc. 

Usage & Application Tips

To get the full benefit, here is how one might incorporate the product into their daily routine, along with suggested best practices and cautions.

Suggested Routine Placement

1. Morning (Daytime use)
   This product is designed largely as a daytime base / tone-up product, due to its SPF and color correcting function.

2. After basic skincare, before makeup
   After cleansing, toning, serum, moisturizer (if used), this should be applied before makeup — just like a primer or base. Many descriptions call it a “makeup base” or primer.

3. Application method

   • Dispense a moderate amount (pea-to-finger sized)

   • Dot onto key areas (forehead, cheeks, nose, chin)

   • Use fingers (or sponge) to pat / blend outward

   • Focus on blending the green tint fully so it turns into beige / natural tone

4. Timing before sun exposure
   Some descriptions advise applying it at least ~15 minutes before going out to let it settle / bind on skin.

5. Makeup layering
   Because it's also correcting tone, you can apply makeup (foundation, etc.) on top. However, to preserve the corrective effect, use light layers so as not to completely mask what the product is doing underneath.

Frequency & Suitability

• It is intended for daily use, particularly in the daytime.

• Suitable for those who experience facial redness, rosacea-like flushing, post-acne redness, sensitive skin — particularly people who want a combined corrective + protective base.

• Works for all skin types (dry, normal, combination, oily), though for very dry skin one might need an additional hydrating base under it. Many listings state “recommended skin type: all type.” 

Tips & Best Practices

• Use thin, even layers. Many users comment that heavy application can lead to an unnatural finish.

• Make sure to blend fully so that the green pigment shifts to natural hue.

• Use additional sunscreen / reapply if you’ll be in the sun, especially if you sweat / rub / exposure is high — even though it has SPF.

• On humid / oily days, blotting or light translucent powder might help reduce shine without interfering with the tone-up effect.

• Patch test before full-face use — especially since it contains color, botanical extracts, and UV filters.

What to Expect: Effects & Visuals

Here is what users might see or feel when using this product:

Immediately After Application

• The green base helps neutralize visible redness (e.g. around the cheeks, nose, broken capillaries) — you should notice a more balanced, less “red” look.

• The texture feels smooth, lightweight, and hydrating (not overly greasy or heavy).

• The color should transform from pale green to a more beige / skin-matching hue once blended thoroughly.

During the Day

• Acts as a mild base / primer, helping subsequent makeup layers apply more evenly.

• Offers sun protection (SPF 50+ PA+++), which helps prevent UV-triggered redness or sensitivity.

• Helps keep redness in check by soothing botanicals and barrier-support ingredients.

• Because of color correction, it may reduce the need for heavy color concealers in some zones.

Over Time & With Regular Use

• With consistent use, the skin may appear more even, with fewer fluctuations in redness.

• Redness from irritation, breakouts, or sensitivity may become less noticeable.

• The skin barrier may become calmer, less reactive, improving overall skin texture and appearance.

Limitations, Risks & Considerations

Every product has considerations, and being aware helps manage expectations or avoid adverse effects.

• Not a full-coverage foundation
  While it corrects tone and blurs, it is unlikely to fully mask heavy discoloration or dark spots. Extra concealer or foundation may still be needed for certain areas.

• Risk of “cast” or mismatched shade
  Because it includes pigments and tinting, if not blended well, or used in thick layers, it may appear unnatural (e.g. greenish or ashy zone).

• Sensitivity / Irritation
  Botanical extracts, UV filters, or colorants can occasionally irritate sensitive skin. Always patch test first.

• Breakout or “purging” possibility
  A few users have reported initial “purging” or breakouts when using Numbuzin products. A Reddit user noted that No.2 should be layered thinly for a natural finish, but heavy usage or mis-layering might aggravate skin.

• Oxidation / Shift in Color
  Over time, the tone-up effect might shift slightly depending on skin oils, environment, or formula stability.

• Not a substitute for full sunscreen reapplication
  Even though it offers SPF, reapplication is still important in real-world use.

Comparisons & User Feedback

Comparisons & Context

• Some users compare No.1 (Pure Glass Tone Up) and No.2 (Goodbye Redness) versions of Numbuzin, indicating different target effects (No.2 being more for redness correction). A user shared swatches noting how the green tint shifts to beige / olive on their skin. 

• In an AsianBeauty forum, a user recommended using No.2 “thinly for natural tone up finish,” and mentioned that it helped reduce redness of acne spot by ~50%, while somewhat mattifying oily skin.

• Some users caution about combining it with strong actives (like multiple vitamin C or harsh exfoliants), as layering too many potentially irritating products may lead to skin stress. 

User Praises & Critiques

Positives often mentioned:

• Good tone-up / color correction for mild redness

• Feels lightweight, comfortable on skin

• Useful as a combined base + sunscreen, especially on less intensive makeup days

• The green-to-beige transformation is appreciated by users dealing with rosacea or flushing

Critiques or caution points:

• Some report that heavy or improper layering can lead to obvious tint or patchiness

• Occasional breakouts or skin reactions (especially when combining with other actives)

• Some feel the effect is subtle and not enough for severe discoloration

• Others mention that it may not fully replace foundation / concealer for many use cases
