How to use
HOW TO USECleanse & Prep
Start with clean, dry skin. Apply toner if desired and wait for it to absorb.
Apply Serum
Dispense 2-3 drops onto fingertips. Gently press and pat into face, focusing on areas with dark spots or uneven tone.
Wait & Layer

Frequently asked questions
FAQThis serum is NOT recommended during pregnancy or breastfeeding. It contains Arbutin (a hydroquinone derivative) and Kojic Acid, both of which have limited safety data during pregnancy. While niacinamide, hyaluronic acid, and most vitamin C derivatives in the formula are pregnancy-safe, the presence of arbutin and kojic acid means you should consult your healthcare provider before use or consider pregnancy-safe alternatives.
Use with caution if you're prone to fungal acne. The formula contains Arginine (which can feed malassezia in the presence of lipids) and Hydrogenated Lecithin. While the serum is oil-free and some users with FA have reported success, it's not strictly FA-safe. If you have fungal acne, consider patch testing first or opting for a verified FA-safe alternative like Good Molecules Niacinamide Serum.
Yes, with some guidelines. This serum already contains multiple forms of vitamin C, so avoid layering with pure L-Ascorbic Acid serums (may reduce efficacy). For retinol: apply this serum first, wait 5 minutes, then apply retinol. For AHA/BHA: consider alternating AM/PM usage to prevent over-exfoliation. Niacinamide actually pairs well with these actives and can reduce irritation.
This serum works well for most skin types, especially oily, combination, and normal skin. The lightweight, oil-free formula with 10% niacinamide helps control sebum. Dry skin types may need a richer moisturizer on top. Sensitive skin can use it but should patch test first as the high niacinamide concentration may cause initial tingling. Ideal for those targeting dark spots, hyperpigmentation, and dullness.
Results vary by individual, but typically: Week 1-2 shows improved hydration and glow. Week 2-4 brings visible brightening and fading of dark spots. Week 4-8 shows significant improvement in hyperpigmentation and skin texture. For optimal results, use consistently twice daily with SPF protection. Some users report noticeable acne scar fading in as little as 2 weeks.
Apply after cleansing and toning, before heavier products. The order is: Cleanser → Toner → THIS SERUM → Other serums (if any) → Moisturizer → Sunscreen (AM). Wait 30-60 seconds for absorption before the next step. Can be used both morning and evening. Always use SPF 30+ during the day when using brightening actives.
This serum has a low comedogenic rating of 1/5 and is unlikely to clog pores for most people. It's oil-free, silicone-free, and contains no known pore-clogging ingredients. The 10% niacinamide actually helps minimize pore appearance and regulate oil production. However, everyone's skin is different - if you're very acne-prone, patch test first.
The Period After Opening (PAO) is 12 months. Mark the date you open the bottle and use within one year. Store in a cool, dry place away from direct sunlight to preserve the vitamin C content. If you notice any color change (yellowing), unusual smell, or texture change, discontinue use as this may indicate oxidation.
Verdict: The Arencia Holy Hyssop Serum 12 is an impressive K-beauty brightening serum that delivers on its promises. The combination of 10% niacinamide, 12% Vita ACE Complex, and French hyssop extract creates a powerful formula for tackling dark spots, hyperpigmentation, and dull skin. The addition of 5 peptides adds anti-aging benefits rarely found at this price point. While the small bottle size and pregnancy/FA concerns are drawbacks, the lightweight texture, clean formula, and visible results within 2-4 weeks make it a solid choice for those seeking a multi-functional brightening serum. Best suited for oily to combination skin targeting hyperpigmentation.
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.
