Ingredient breakdown
INGREDIENTSSodium Hyaluronate 3.5%Proven
The salt form of hyaluronic acid, a powerful humectant that can hold up to 1000x its weight in water. This formula uses multiple molecular weights (5 kDa to 1800 kDa) for comprehensive hydration.
- High MW (1800 kDa): Forms a moisture-retaining film on skin surface for instant smoothing
- Medium MW: Hydrates mid-layers of epidermis for plumping effect
- Low MW (5 kDa): Penetrates deeper for regeneration and collagen support
Salix Nigra Bark ExtractNatural Preservative
Black willow bark extract serves as a natural antimicrobial agent and gentle exfoliant. Contains natural salicin which helps maintain skin clarity without irritation.
- Function: Natural preservative and mild keratolytic
- Benefit: Keeps formula stable without harsh synthetic preservatives
GlycerinHumectant
Organic vegetable glycerin (non-palm derived) that draws moisture into the skin. Studies show glycerin can be even more effective than hyaluronic acid as a humectant.
- Source: Organic, non-palm derived vegetable glycerin
- Research: 2016 study found glycerin more effective than AHAs and HA as a humectant
Levulinic Acid & Sodium LevulinatePreservative System
Plant-derived antimicrobial agents that work together to preserve the formula naturally. Derived from cellulose degradation, these gentle preservatives maintain product stability.
- Source: Plant-derived from cellulose
- Function: Natural preservation system replacing synthetic alternatives

Frequently asked questions
FAQYes, this serum is completely safe during pregnancy and breastfeeding. Hyaluronic acid is a naturally occurring substance in the body and does not pose any risk when applied topically. The formula contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens that would be concerning during pregnancy. All 6 ingredients are pregnancy-safe.
Yes, this serum is 100% fungal acne safe. The formula contains no ferments, fatty acids (C11-C24), esters, or polysorbates that feed malassezia yeast. All 6 ingredients (water, sodium hyaluronate, willow bark extract, glycerin, levulinic acid, sodium levulinate) are safe for fungal acne-prone skin.
Yes! Hyaluronic acid pairs beautifully with virtually all actives. Apply HA serum first to hydrate, then layer your actives on top. It can help buffer potential irritation from retinol or acids while boosting hydration. For vitamin C, apply the HA serum after the vitamin C for best results.
This serum is excellent for all skin types, but particularly beneficial for dehydrated, dry, sensitive, and acne-prone skin. Its lightweight gel texture works well for oily and combination skin, while its intense hydration helps dry skin. The minimalist, fragrance-free formula is ideal for sensitive and reactive skin types.
You'll feel immediate hydration benefits after the first application. Visible improvements in skin texture and fine lines typically appear within 1-2 weeks. Clinical studies showed significant wrinkle reduction and improved elasticity after 28 days of consistent use. Continue use for cumulative anti-aging benefits.
Apply after cleansing and toning, but before heavier treatments and moisturizers. The general rule is thinnest to thickest consistency. For best results, apply to slightly damp skin (after toner or misting with water) to maximize hydration, then seal with a moisturizer or facial oil.
No, this serum has a comedogenic rating of 0/5 and will not clog pores. The formula contains no oils or comedogenic ingredients. It's specifically suitable for acne-prone skin and is also fungal acne safe. The lightweight gel texture absorbs quickly without leaving any pore-clogging residue.
The serum has a PAO (Period After Opening) of 9 months when used as directed. If you customize the serum by adding other actives, the shelf life reduces to 3 months. Store in a cool, dry place away from direct sunlight and heat to maintain efficacy throughout its shelf life.

Voted Best Aroma-Zone Product of 2023 with over 23,000 positive reviews, it's pregnancy-safe, fungal acne-safe, and suitable for all skin types.

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.
