Rule 1: order matters
Ingredients are listed roughly from highest to lowest concentration (ingredients under about 1% can appear in any order at the end). In a good cactus gel, Opuntia Ficus-Indica Stem Extract should be first or very near the top.
A real example
Here is the published ingredient list of a widely sold Korean cactus soothing gel (YADAH Cactus Soothing Gel, as listed by Olive Young US):
Opuntia Ficus-Indica Stem Extract, 1,2-Hexanediol, Glycerin, Water, Butylene Glycol, Carbomer, Arginine, Allantoin, Hydroxyacetophenone, Caprylyl Glycol, Dipropylene Glycol, Dipotassium Glycyrrhizate, Panthenol, Disodium EDTA
Let us decode it:
| Ingredient | What it does |
|---|---|
| Opuntia Ficus-Indica Stem Extract | The cactus extract; main hydrating base |
| 1,2-Hexanediol | Humectant that also boosts preservation |
| Glycerin | Classic humectant; draws water into the skin's surface |
| Water | Solvent |
| Butylene Glycol, Dipropylene Glycol | Humectants and texture helpers |
| Carbomer | Thickener; creates the gel |
| Arginine | Neutralises the carbomer to set pH and texture |
| Allantoin | Skin-conditioning, commonly used for comfort |
| Hydroxyacetophenone, Caprylyl Glycol | Antioxidant / preservative boosters |
| Dipotassium Glycyrrhizate | Licorice-derived soothing agent |
| Panthenol | Pro-vitamin B5, skin conditioning |
| Disodium EDTA | Chelator that helps stability |
Nothing unusual here: a cactus base, humectants, a gel system and a preservation system. Ingredient lists can change, so always check the current packaging.
Rule 2: understand "95%" claims
"95% cactus extract" usually refers to the extract as supplied, which is largely plant water. It is a fair marketing claim, but it does not mean the gel is 95% concentrated "actives".
Rule 3: flag ingredients for sensitive skin
- Fragrance / parfum and essential oils: common causes of irritation and allergy.
- Alcohol denat. high on the list: can feel stinging and drying.
- Colourants: a bright green gel is coloured; the extract itself is not that green.
- Menthol or camphor: add a cooling sensation, but can irritate.
Rule 4: if there is no INCI list, do not buy
On marketplaces, look for a photo of the back of the pack. No list, or a list that does not match the product name, is a reason to move on. More tips in our AliExpress checklist.
Frequently asked questions
Why does my cactus gel contain preservatives?
Water-based gels can grow bacteria and mould. Preservatives keep them safe for months of use. A gel with no preservation system is riskier, not safer.
What does INCI mean?
International Nomenclature of Cosmetic Ingredients, the standardised naming system used on cosmetic labels.
Is carbomer bad for skin?
Carbomer is a common thickener used in many gels and is generally considered low risk. It is what gives a soothing gel its jelly texture.
