Where it fits in your routine
ROUTINEUse morning and night. Apply after toner and before moisturizer. If layering with other serums, apply thinnest to thickest. Always follow with SPF in the morning.
How to use
HOW TO USECleanse Your Face
Start with a gentle cleanser suited for your skin type. Pat dry with a clean towel, leaving skin slightly damp for better absorption.
Apply 2–3 Drops
Dispense 2–3 drops onto your fingertips or palm. A little goes a long way with this concentrated formula.
Gently Pat Into Skin
Press and pat the serum across your face and neck. Avoid rubbing — patting helps the serum absorb deeper and reduces irritation risk.
Follow with Moisturizer & SPF
Wait 15–30 seconds until absorbed, then layer your moisturizer. In the morning, always finish with sunscreen SPF 30+.

Skin type compatibility
SKIN TYPESLightweight gel texture absorbs fast without added shine. 5% niacinamide helps regulate sebum production throughout the day.
Hyaluronic acid and glycerin provide hydration, but very dry skin may need a richer moisturizer layered on top for adequate moisture.
Balances oily T-zone while hydrating drier cheeks. Lightweight enough to not overwhelm any zone of the face.
Specifically designed for sensitive skin. Fragrance-free, minimal ingredients, and 5% niacinamide concentration avoids the irritation risk of 10% formulas.
Low comedogenic rating (1/5), anti-blemish niacinamide, and soothing botanicals make this an ideal daily serum for breakout-prone skin.

Budget-friendly alternatives (dupes)
DUPESHigher niacinamide concentration (10% vs 5%) with added zinc for oil control. More widely available globally but may be too strong for very sensitive skin. Lacks snail mucin and aloe vera.
Focuses on snail mucin (96%) for repair and hydration. No niacinamide but excellent for soothing and texture repair. Larger 100 mL size offers better value per mL.
Higher 10% niacinamide concentration in a simple, clean formula. No snail mucin, aloe vera, or HA. More focused on oil control and pore minimization.

Frequently asked questions
FAQYes. This serum contains no retinoids, salicylic acid, hydroquinone, benzoyl peroxide, or chemical sunscreens. All 12 ingredients are considered safe for use during pregnancy and breastfeeding. However, always consult your healthcare provider before introducing new products to your routine during pregnancy.
Use with caution. While the formula is free of ferments, fatty acids, esters, and polysorbates, it does contain Propylene Glycol, which some sources identify as potentially feeding Malassezia yeast. If you have confirmed fungal acne, do a patch test on a small affected area for several days before full application.
Yes. Niacinamide at 5% is compatible with most actives. For best results: use niacinamide and vitamin C at different times (e.g., niacinamide at night, vitamin C in the morning). It layers well with AHAs and BHAs. When using with retinol, apply niacinamide first as a buffer to reduce potential irritation.
This serum is designed for all skin types but excels for sensitive, combination, oily, and acne-prone skin. The gentle 5% niacinamide concentration was specifically chosen for sensitive skin that may react to higher-strength formulas (10%+). Dry skin types can use it but should layer a richer moisturizer on top.
Hydration benefits are noticeable within the first 1–2 weeks. Reduced breakouts and calmer skin typically appear at weeks 3–4. Visible improvements in dark spots, pore size, and overall skin clarity generally take 6–8 weeks of consistent twice-daily use. Full barrier strengthening results develop over 8–12 weeks.
Apply as Step 3 in your routine: after cleansing and toning, before moisturizer and sunscreen. It goes on after any watery toners but before heavier creams or oils. Use morning and evening for best results.
No. This serum has a comedogenic rating of 1 out of 5 (very low). It is free of heavy oils, waxes, and known pore-clogging ingredients. The lightweight gel formula is designed to absorb quickly without leaving residue. It is suitable for acne-prone and congested skin types.
The serum has a Period After Opening (PAO) of 12 months. The 30 mL bottle typically lasts 4–6 weeks when used twice daily (2–3 drops per application). Store in a cool, dry place away from direct sunlight. The pump bottle helps minimize contamination and oxidation.
Verdict: The Dermorepubliq 5% Niacinamide + Hyaluronic Acid Serum is an excellent entry-level niacinamide serum — especially for those with sensitive or reactive skin who find 10% formulas too aggressive. With only 12 clean ingredients, no fragrance, and the bonus of snail mucin and aloe vera, it delivers gentle but effective blemish control, hydration, and barrier support at an unbeatable price point. The main trade-offs are the small 30 mL size and gradual (not dramatic) results. For sensitive Filipino skin in a tropical climate, this is one of the best value-for-money serums available.
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.
