π¬ Ingredient Breakdown
π§ Hyaluronic Acid-5 Complex Proven
A sophisticated blend of five different forms of hyaluronic acid at varying molecular weights to hydrate multiple layers of the skin. Includes standard HA, Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate (mini HA), Sodium Acetylated Hyaluronate (super HA), and Sodium Hyaluronate Crosspolymer.
- Mechanism: Each molecular weight targets a different skin depth - high MW for surface hydration, low MW for deeper penetration
- Research: Sodium Hyaluronate Crosspolymer has 5x the water-binding capacity of regular HA
- Benefit: Can hold up to 1000x its weight in water
𧬠Polyglutamic Acid Proven
A natural amino acid polymer that provides intense hydration and creates a moisture-locking film on the skin surface. Often called "the new hyaluronic acid" for its superior moisture retention.
- Capacity: Holds up to 4-5x more moisture than hyaluronic acid
- Function: Forms a hydrating film that prevents transepidermal water loss (TEWL)
- Synergy: Works synergistically with HA to enhance overall hydration
πΏ Urea Proven
A natural moisturizing factor (NMF) found naturally in skin that provides deep hydration and mild keratolytic (exfoliating) properties. Makes up about 7% of the skin's natural moisture factors.
- Function: Humectant that draws moisture into skin while improving barrier function
- Research: Enhances antimicrobial peptide expression and supports skin barrier repair
- Safety: Pregnancy-safe and fungal acne-safe ingredient
π Glycerin High Proven
One of the most effective and well-researched humectants in skincare. Found naturally in skin and has been used safely for over 50 years.
- Comedogenic Rating: 0 - will not clog pores
- Research: Studies show glycerin is more effective than AHAs and HA as a humectant
- Function: Attracts water, supports skin barrier, protects against irritation
π± Aloe Barbadensis Leaf Juice Promising
Soothing botanical extract with anti-inflammatory properties that calms and hydrates irritated skin. Contains salicylates, polysaccharides, and other beneficial compounds.
- Benefits: Moisturizing, anti-inflammatory, wound healing support
- Safety: Safe for sensitive, acne-prone, and pregnancy skin

π Where It Fits in Your Routine
Apply after cleansing and toning, before heavier serums and moisturizers. Best applied to slightly damp skin to maximize hydration. Can be used AM and PM.
π How to Use
Cleanse & Prep
Start with clean, slightly damp skin. The serum works best when applied to damp skin as hyaluronic acid draws in moisture.
Dispense & Apply
Use 3-4 drops and gently pat onto face and neck. A little goes a long way - the serum spreads easily.
Wait & Layer
Allow 30 seconds for absorption, then follow with moisturizer to seal in hydration. Can also be mixed with primer for a smoothing makeup base.

Yes! This serum is fungal acne safe. It contains no ferments, fatty acids in the C12-C24 range, fatty acid esters, polysorbates, or oils that can feed Malassezia yeast. The hydrating ingredients (glycerin, HA, urea, polyglutamic acid) are all safe for fungal acne-prone skin.
Absolutely! This hydrating serum is specifically designed to layer well with other products. It pairs excellently with retinol (apply serum first, then retinol), vitamin C (can use together or at different times), and exfoliating acids like AHAs and BHAs. The hydrating formula can actually help buffer potential irritation from these actives.
This serum works well for ALL skin types - dry, oily, combination, sensitive, and acne-prone. It's particularly excellent for dehydrated skin, sensitive skin needing gentle hydration, acne-prone skin that needs non-comedogenic moisture, and anyone looking for a lightweight hydrator that won't feel heavy or greasy.
You'll notice immediate hydration and softness right after the first application. Within 1-2 weeks of consistent use, skin texture improves noticeably. By 3-4 weeks, you should see visible plumping, a dewy glow, and reduced appearance of fine lines. Long-term use (2+ months) helps strengthen the moisture barrier for lasting results.
Apply after cleansing and toning, but before heavier serums, moisturizers, and sunscreen. For best results, apply to slightly damp skin so the hyaluronic acid can draw in that extra moisture. You can use it both morning and evening. It can also be mixed with your primer for a smoothing makeup base.
No, this serum has a comedogenic rating of 0/5 and will not clog pores. All ingredients, including glycerin and the various forms of hyaluronic acid, are non-comedogenic. The formula is specifically designed to be acne-friendly and suitable for acne-prone and congested skin.
The serum has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight. Since you only need 3-4 drops per application, the 30ml bottle typically lasts 2-3 months with twice-daily use, well within the shelf life window.

The sophisticated 5-form hyaluronic acid complex combined with polyglutamic acid provides superior, long-lasting hydration that visibly plumps and smooths skin. Its clean, minimal formula makes it safe for virtually everyone - including pregnant women, those with fungal acne, sensitive skin, and acne-prone skin types. While the price point is higher than budget alternatives like The Ordinary, the advanced formula and elegant texture justify the investment for those who want a premium hydrating serum without any concerning ingredients. A solid choice for anyone seeking effective, worry-free hydration.
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 Β«promisesΒ» 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.
