Ingredient breakdown
INGREDIENTSSodium Hyaluronate (Hyaluronic Acid)Proven
The sodium salt form of Hyaluronic Acid with a smaller molecular size that penetrates deeper into skin. Acts as a powerful humectant that can hold up to 1000x its weight in water.
- Function: Hydrates skin by drawing moisture from the environment and deeper skin layers
- Research: Clinically proven to improve skin hydration, elasticity, and reduce fine lines
Niacinamide (Vitamin B3)Proven
A versatile, well-researched active ingredient that strengthens the skin barrier, reduces redness, and helps regulate sebum production.
- Function: Improves skin texture, minimizes pores, and brightens uneven skin tone
- Research: Studies show 2-5% niacinamide improves barrier function and reduces hyperpigmentation
GlycerinProven
One of the most effective and well-studied humectants in skincare. Naturally found in skin and draws moisture to keep skin hydrated and supple.
- Function: Attracts water to the skin surface and helps maintain skin's natural moisture balance
- Research: Proven safe and effective humectant with decades of clinical use
Saccharide Isomerate Pentavitin®Promising
A plant-derived sugar complex that mimics the natural carbohydrates found in skin. Provides deep, long-lasting hydration by binding directly to skin cells.
- Function: Creates a moisture reservoir that hydrates for up to 72 hours
- Research: Studies show it binds to keratin and provides longer-lasting hydration than HA alone
Propanediol & Pentylene GlycolSupporting
Plant-derived humectants that enhance product texture and help other ingredients penetrate better. Also provide mild antimicrobial properties.
- Function: Solvent, humectant, and penetration enhancer
- Source: Derived from renewable plant sources (corn)

How to use
HOW TO USECleanse Your Face
Start with clean skin. Use your preferred cleanser and pat dry with a soft towel, leaving skin slightly damp for better absorption.
Apply to Damp Skin
Take a pea-sized amount and dot onto forehead, cheeks, nose, and chin. Apply while skin is still slightly damp to maximize hydration.
Gently Press & Pat
Use fingertips to gently press and pat the gel into skin until fully absorbed. Avoid rubbing to prevent irritation.

In the morning, always follow with a broad-spectrum sunscreen. At night, you can layer a heavier moisturizer on top if needed.

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.
