Ingredient breakdown

INGREDIENTS

Niacinamide 20%Proven

Also known as Vitamin B3, Niacinamide is a multitasking powerhouse that strengthens the skin barrier, regulates sebum, fades hyperpigmentation, and reduces the appearance of fine lines and wrinkles.

  • Mechanism: Converts to NAD+ in cells, boosting cellular energy and repair processes
  • Efficacy: Studies show 2-5% effective; 20% provides intensive results for stubborn concerns
  • Benefits: Oil control, pore minimizing, brightening, anti-aging, barrier repair
High concentrations (above 10%) may cause mild flushing or tingling in sensitive individuals. Build up tolerance gradually.

Arbutin Key ActiveProven

A natural skin brightening agent derived from bearberry plants that inhibits tyrosinase activity to reduce melanin production and fade dark spots without irritation.

  • Source: Derived from bearberry, cranberry, and blueberry plants
  • Action: Inhibits tyrosinase enzyme to reduce melanin synthesis
  • Safety: Gentler alternative to hydroquinone with no rebound hyperpigmentation
Safe for long-term use and pregnancy. Works synergistically with Niacinamide for enhanced brightening.

Zinc PCA Key ActiveProven

A zinc salt combined with PCA (pyrrolidone carboxylic acid) that regulates sebum production, has antimicrobial properties, and helps maintain skin hydration.

  • Oil Control: Clinically shown to reduce sebum production after 28 days of use
  • Antimicrobial: Effective against P. acnes bacteria between 0.1-0.25%
  • Hydration: L-PCA component is a natural moisturizing factor (NMF)

10 Types of Hyaluronic Acid Multi-WeightProven

A complex of different molecular weights of Hyaluronic Acid that hydrate at multiple skin levels - from the surface to deeper layers - for plump, bouncy skin.

  • High MW (1000+ kDa): Forms a moisture-locking film on skin surface
  • Medium MW (100-300 kDa): Supports skin repair and barrier function
  • Low MW (50 kDa): Penetrates deeper to plump fine lines from within

Adenosine SupportingProven

A naturally occurring compound with proven anti-aging benefits. Stimulates collagen production and smooths fine lines while providing soothing properties.

  • Anti-Wrinkle: Approved anti-wrinkle ingredient by Korean FDA at 0.04%+
  • Collagen Boost: Promotes fibroblast activity for firmer skin

Frequently asked questions

FAQ

Yes, this serum is safe during pregnancy and breastfeeding. Niacinamide (Vitamin B3) is FDA-approved for use during pregnancy and nursing. The formula contains no retinoids, salicylic acid, hydroquinone, or other pregnancy-restricted ingredients. However, always consult your healthcare provider before adding new products to your routine during pregnancy.

Yes, this serum is fungal acne safe. It's free from ferments, fatty acids, fatty alcohols, esters, and polysorbates that feed malassezia yeast. The formula has been verified as FA-safe by multiple ingredient analyzers including SkinSort and SkinCarisma. It's an excellent choice for those prone to fungal acne.

Yes, but with some guidelines. Niacinamide pairs well with most ingredients. For Vitamin C: Use in separate routines (one AM, one PM) or wait 15-20 minutes between applications. For Retinol: Can be used together - niacinamide actually helps buffer retinol irritation. For AHA/BHA: Safe to use together, but if you experience irritation, alternate days. Always introduce one active at a time.

This serum is best suited for oily, combination, and acne-prone skin types. The Zinc PCA regulates sebum, while the lightweight formula absorbs without adding shine. It also works well for normal skin concerned with brightening and anti-aging. Dry skin types can use it but should layer with a rich moisturizer. Sensitive skin should patch test first due to the high 20% concentration.

Initial results (hydration, smoother texture) can be noticed within 1-2 weeks. Oil control and pore minimizing effects typically appear by week 3-4. For hyperpigmentation and dark spots, expect 6-12 weeks of consistent use. Fine line improvement may take 8-12 weeks. Best results come with daily, consistent use over 3+ months.

Apply after cleansing and toning, before heavier creams and moisturizers. The order is: Cleanser → Toner → This Serum → Essence (optional) → Moisturizer → Sunscreen (AM). Use 2-3 drops and gently pat into skin. Can be used both morning and evening. Always follow with SPF during daytime.

No, this serum has a comedogenic rating of 0/5. It's oil-free, silicone-free, and contains no pore-clogging ingredients. In fact, the Zinc PCA and Niacinamide actively help unclog pores and regulate sebum. It's safe for acne-prone skin and won't cause breakouts.

The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal efficacy. The 20ml bottle typically lasts 1-2 months with twice-daily use (2-3 drops per application). Store in a cool, dry place away from direct sunlight to maintain potency.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: Isntree Hyper Niacinamide 20 Serum is an impressive K-beauty powerhouse for those seeking serious brightening, pore-minimizing, and oil-control benefits. The combination of 20% Niacinamide, Arbutin, Zinc PCA, and 10 types of Hyaluronic Acid delivers multi-targeted results in a clean, fungal acne safe, and pregnancy-safe formula. While the small 20ml size and potent concentration may not suit everyone, it's an excellent choice for oily and combination skin types battling hyperpigmentation and enlarged pores. For best value, consider if you need the full 20% concentration or if a gentler 10-15% alternative would suffice.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
