Texture & feel
SENSORYMulti-Active Brightening
5% Niacinamide teams up with GENOWHITE, G2 Light and Fision GlowPlex to fade dark spots and even out skin tone for a visibly brighter look.
Lightweight & Fast-Absorbing

Hydration & Barrier Support
Glycerin, Hydroxyethyl Urea and Sodium Hyaluronate flood skin with moisture while Allantoin soothes.
Gentle & Clean
Fragrance-free, alcohol-free and free of common irritants — formulated to minimize stinging and reactivity.
Safety & compatibility
SAFENiacinamide, hyaluronic acid, glycerin, allantoin and Vitamin E are generally considered safe. No retinoids, salicylic acid or hydroquinone. Always confirm with your doctor.
Contains no problematic fatty acids, esters or polysorbates that feed malassezia — a good fit for fungal-acne-prone skin.
Oil-free, humectant-based formula with a comedogenic rating around 1/5. Unlikely to clog pores.
Niacinamide is stable and plays well with retinol, AHA/BHA, vitamin C, peptides and hyaluronic acid.
Well-tolerated and fragrance-free, but very reactive skin should patch test first, especially when combining with strong actives.
Safe for AM use, but always follow with a broad-spectrum sunscreen to protect and maintain brightening results.
Ingredient breakdown
INGREDIENTSNiacinamide 5%Proven
The hero active. A multitasking form of Vitamin B3 that brightens, strengthens the skin barrier, regulates oil and visibly fades dark spots and post-acne marks.
- Source: Research shows 4–5% niacinamide is an effective concentration for fading dark spots and evening tone.
- Source: It converts to NAD in skin cells, supporting repair, collagen and barrier strength.
Glycerin ~4%Proven
A gold-standard humectant that pulls water into the skin and helps strengthen the moisture barrier, keeping skin soft, plump and hydrated.
- Source: A 2016 study found glycerin to be a more effective humectant than AHAs and hyaluronic acid.
Sodium Hyaluronate <1%Proven
The salt form of hyaluronic acid. Excellent at holding water, it boosts surface hydration so skin looks dewy and feels supple.
- Source: Naturally present in the body; acts as a humectant that binds many times its weight in water.
Tocopheryl Acetate (Vitamin E) <1%Proven
A stable form of Vitamin E that acts as an antioxidant, protecting skin from free-radical damage that breaks down collagen.

Allantoin ~0.5%Proven
A soothing, skin-protecting ingredient often added alongside actives to calm irritation and support a comfortable feel.
- Source: Studies show higher concentrations can promote wound healing; widely used to soothe sensitive skin.
Hydroxyethyl Urea ~3%Promising
A water-loving humectant that helps the skin retain moisture, contributing to the serum's plumping, hydrating feel.
- Source: Functions similarly to urea-based humectants to improve skin hydration and softness.
Betaine <3%Promising
A gentle humectant that hydrates, soothes irritation and helps balance the skin. Often used to improve the feel of active formulas.
- Source: Typically used at 3–5%; studies suggest it can help even skin tone and reduce redness.
Biosaccharide Gum-1 <2%Promising
A fermented sugar prized for soothing, long-lasting hydration and a silky, non-sticky feel.
- Source: Manufacturer testing showed it reduced lactic-acid irritation by nearly half while keeping skin hydrated.
Pisum Sativum (Pea) Extract <1%Promising
A plant-derived skin-conditioning extract included to support a smoother, healthier-looking complexion.
- Source: Pea-derived peptides are studied for skin-firming and conditioning benefits.
Chenopodium Quinoa Seed Extract <1%Promising
An antioxidant-rich seed extract used as a skin conditioner to support softness and overall skin health.

Budget-friendly alternatives (dupes)
DUPESA near-identical Indonesian rival at 5% niacinamide, with added Centella and papaya extracts for extra soothing. Very comparable brightening and price.
Higher 10% niacinamide plus zinc for oil control, but a simpler formula with no dedicated brightening complexes and a higher chance of pilling.
A clean, minimalist niacinamide serum focused on tone and oil. Lacks the extra hydration boosters and brightening actives Hanasui layers in.

Frequently asked questions
FAQIts key ingredients — niacinamide, hyaluronic acid, glycerin, allantoin and Vitamin E — are generally considered safe during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone or chemical sunscreen filters. As with any product, confirm with your doctor or OB-GYN before use.
Yes. The formula is free of the fatty acids, esters and polysorbates that typically feed malassezia, making it a suitable choice for people prone to fungal acne.
Yes. Niacinamide is stable and pairs well with retinol, vitamin C, AHAs and BHAs. To minimize irritation, you can use stronger actives at night and the brightening serum in the morning, or simply layer thinner to thicker. Patch test when combining multiple actives.
It's excellent for oily, combination and acne-prone skin thanks to its lightweight, oil-free texture, and good for sensitive skin given its fragrance-free, soothing formula. Dry skin can use it too, but should seal it with a richer moisturizer.
Many users notice brighter, more hydrated skin within the first 7 days. More even tone tends to appear around weeks 2–4, while dark spots and post-acne marks fade gradually over 4–8+ weeks of consistent daily use paired with sunscreen.
Apply after cleansing (and toner, if used) and before heavier serums and moisturizer. Use it morning and/or evening, and always finish your morning routine with a broad-spectrum sunscreen.
No. It's an oil-free, humectant-based formula with a comedogenic rating around 1/5, so it's unlikely to clog pores and is well-suited to acne-prone skin.
Roughly 6 months after opening — refer to the open-jar (PAO) symbol on the packaging. Store it in a cool, dry place out of direct sunlight to keep the formula fresh.
Verdict: Hanasui Power Bright Serum is a standout budget brightener. Its 5% niacinamide plus supporting brightening complexes, hydrators and soothers deliver visible glow and a more even tone — often within a week — in a lightweight, fragrance-free and fungal-acne-safe formula. The slightly tacky finish and small 20ml size are minor trade-offs against an exceptional price. For anyone wanting affordable, gentle brightening for oily, combination or acne-prone skin, it's an easy recommendation.
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.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
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.
