Texture & feel
SENSORYSebum Control
Zinc PCA at 1% concentration is clinically shown to reduce sebum production after 28 days. Keeps oily skin balanced and shine-free throughout the day.
Brightening & Even Tone
10% Niacinamide inhibits melanin transfer to skin cells, gradually fading dark spots, post-acne marks, and hyperpigmentation for a more even complexion.
Pore Minimizing
High-concentration niacinamide helps restore skin elasticity around pores, visibly tightening and reducing the appearance of enlarged pores over time.
Barrier Strengthening
Niacinamide boosts ceramide synthesis, reinforcing the skin's natural moisture barrier. Centella Asiatica extract provides additional soothing and repair benefits.
Safety & compatibility
SAFEContains no retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. All ingredients are considered safe for use during pregnancy and breastfeeding.
Free from fermented ingredients, fatty acids, esters, polysorbates, and oils that feed Malassezia yeast. Safe for fungal acne-prone skin.
Comedogenic rating of 1/5. Contains no pore-clogging oils or heavy emollients. Water-based gel formula is unlikely to clog pores.
Fragrance-free, alcohol-free, and silicone-free formula. Centella Asiatica and Arnica extracts provide anti-inflammatory soothing. Patch test recommended for very reactive skin.
High-concentration niacinamide (10%) may reduce the efficacy of pure Vitamin C (L-Ascorbic Acid) when used together. Apply them at different times (AM/PM) for best results.
Niacinamide pairs well with retinol (may reduce retinol irritation) and can be layered with AHA/BHA exfoliants. Wait 5-10 minutes between applications.
Ingredient breakdown
INGREDIENTSNiacinamide (Vitamin B3) 10%Proven
A powerhouse vitamin with extensive clinical evidence for multiple skin benefits. At 10% concentration, it targets oil control, brightening, pore reduction, anti-aging, and barrier repair simultaneously.
- Sebum Control: Reduces sebum production and visibly controls oiliness at concentrations of 4% and above.
- Brightening: Inhibits melanosome transfer to keratinocytes, fading dark spots and evening skin tone.
- Barrier Repair: Increases ceramide and fatty acid synthesis, strengthening the skin's moisture barrier.
- Anti-Aging: Stimulates collagen production, smooths fine lines and wrinkles at 4-5% concentration.
Zinc PCA 1%Proven
A synergistic combination of zinc and L-pyrrolidone carboxylic acid (L-PCA). The zinc helps normalize sebum production and limit acne-causing bacteria, while L-PCA (a natural moisturizing factor) enhances hydration and boosts zinc bioavailability.
- In-vivo Study: 1% Zinc PCA statistically significantly reduced sebum production after 28 days of application.
- Antimicrobial: Strong in-vitro activity against P. acnes bacteria at 0.1-0.25% concentration.
- Collagen Support: 2011 research suggests Zinc PCA may promote type I collagen production (in-vitro).
Centella Asiatica ExtractProven
A legendary soothing botanical widely used in K-beauty. Known for its wound-healing, anti-inflammatory, and barrier-supporting properties. Helps calm redness and irritation while supporting skin repair.
- Active Compounds: Contains asiaticoside, madecassoside, asiatic acid, and madecassic acid.
- Clinical Evidence: Promotes collagen synthesis and reduces inflammation in multiple peer-reviewed studies.
Arnica Montana Flower ExtractPromising
A traditional botanical extract known for its anti-inflammatory and soothing properties. Helps reduce redness and supports skin recovery from irritation and environmental stress.
- Anti-Inflammatory: Contains helenalin and flavonoids that help calm skin inflammation.
- Soothing: Traditionally used to reduce bruising and swelling; provides calming effects in topical skincare.
GlycerinProven
A skin-identical humectant that draws moisture into the upper layers of the skin. It also helps maintain the skin's lipid barrier in a healthy state and protects against irritation. Comedogenicity: 0.
- Hydration: Effective at concentrations as low as 3%, with increased benefits at higher levels for dry skin.
- Barrier Support: Helps keep intercellular lipids in a liquid crystal state for optimal barrier function.

How to use
HOW TO USECleanse & Tone
Start with a gentle cleanser and follow with your toner. Pat your skin dry or leave it slightly damp for better absorption.
Apply 2-3 Drops
Using the dropper, dispense 2-3 drops of serum onto your fingertips or directly onto the face. A small amount goes a long way due to the high concentration.
Gently Pat & Massage
Gently tap and press the serum into your skin using your fingertips. Focus on areas of concern like the T-zone, pores, and dark spots. Avoid rubbing.
Follow With Moisturizer
Wait 30-60 seconds for the serum to absorb, then layer your moisturizer to seal in the active ingredients. In the morning, always finish with sunscreen.
Who is it for?
WHOPerfect for you if:
- You struggle with oily, shiny skin and enlarged pores
- You want to fade dark spots, acne marks, or hyperpigmentation
- You need a lightweight, non-greasy serum for acne-prone skin

- You are looking for an affordable K-beauty niacinamide alternative
Consider alternatives if:

Skin type compatibility
SKIN TYPESThis serum was designed for you. Zinc PCA controls sebum, niacinamide minimizes pores, and the oil-free gel formula absorbs instantly without adding any shine.
Non-comedogenic, fungal acne safe, and antibacterial. Zinc PCA fights P. acnes bacteria while niacinamide fades post-acne marks and reduces inflammation.
Balances oil production in the T-zone without stripping dry areas. Lightweight formula layers easily and does not feel heavy on any zone of the face.
Fragrance-free and gentle with soothing Centella and Arnica extracts. However, 10% niacinamide may be too strong for very reactive skin — start slowly and patch test first.
Provides basic hydration via glycerin and humectants, but lacks rich emollients. Dry skin types should follow with a heavier moisturizer or facial oil to seal in hydration.

Frequently asked questions
FAQYes. This serum contains no retinoids, salicylic acid, hydroquinone, benzoyl peroxide, or chemical sunscreen filters. All 14 ingredients are considered safe for use during pregnancy and breastfeeding. Niacinamide (Vitamin B3) and Zinc PCA are both well-tolerated and widely approved for use by expectant and nursing mothers. As always, consult your healthcare provider if you have specific concerns.
Yes. This formula is free from fermented ingredients, fatty acids, esters, polysorbates, and oils that are known to feed Malassezia yeast. The ingredient list has been cross-referenced with fungal acne-safe databases and contains no triggers. It is one of the few niacinamide serums that is both effective and completely fungal acne safe.
Niacinamide pairs well with retinol — it can actually help reduce retinol-related irritation and dryness. It also works alongside AHA and BHA exfoliants; just wait 5-10 minutes between products. For pure Vitamin C (L-Ascorbic Acid), use at separate times (e.g., Vitamin C in the evening, niacinamide in the morning) as they may reduce each other's effectiveness when applied simultaneously. Vitamin C derivatives like Ascorbyl Glucoside are fine to layer with niacinamide.
This serum is best suited for oily, combination, and acne-prone skin types. The Zinc PCA targets excess sebum production while niacinamide minimizes pores and brightens skin tone. It is also suitable for sensitive skin (fragrance-free, alcohol-free), though those with very reactive skin should start with every-other-day use. Dry skin types can use it but should follow with a rich moisturizer.
Most users notice reduced oiliness and improved texture within the first 1-2 weeks. Visible pore minimizing and sebum control peaks at around 4 weeks (clinically supported by Zinc PCA studies at 28 days). Brightening and dark spot fading typically become noticeable at 4-8 weeks, with full results at 8-12 weeks of consistent twice-daily use.
Apply after cleansing and toning, before your moisturizer. The general rule is thinnest to thickest: cleanser, toner, this serum, then moisturizer, and sunscreen in the morning. Use 2-3 drops morning and evening. If you use multiple serums, apply this one first as it has a lightweight water-based gel texture.
No. This serum has a comedogenic rating of 1/5 (very low). It is completely oil-free and contains no known pore-clogging ingredients. In fact, niacinamide and zinc PCA actively help unclog pores by reducing sebum production and normalizing skin cell turnover. It is safe for acne-prone and congested skin.
The Period After Opening (PAO) is 12 months. Store in a cool, dry place away from direct sunlight. The glass bottle with dropper helps protect the formula from light degradation. With typical twice-daily use (2-3 drops per application), a 30ml bottle lasts approximately 2-3 months.
Verdict: CARE:NEL Niacinamide Zinc Serum is a well-formulated, no-nonsense K-beauty serum that delivers clinically proven actives (10% Niacinamide + 1% Zinc PCA) in an impressively clean 14-ingredient formula. It excels at oil control, pore minimizing, and gradual brightening — especially for oily and acne-prone skin. The addition of Centella Asiatica and Arnica extracts gives it an edge over comparable Western formulas. While the 30ml size is small and it lacks extra actives like hyaluronic acid, the affordable price point and pregnancy/fungal acne-safe profile make it a strong contender in the niacinamide serum category. Best for anyone who wants proven results from a minimal, transparent ingredient list.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.

Ingredients Related to Skin Types
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.
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.
