Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
Bisabolol is a gentle skin conditioner, antioxidant, and soothing ingredient.
It's primary claim to fame is soothing and research shows topically applied bisabolol can quiet the chemical messengers that cause your skin to become inflamed, helping to sooth any irritation.
A clinical study found that applying 0.5% bisabolol daily for 8 weeks produced an average 9% decrease in skin pigmentation. Researchers found it can also suppress the process that leads to excess melanin production in skin.
In vitro studies found that bisabolol combined with propylene glycol significantly increased skin permeability by increasing lipid fluidity in the stratum corneum.
You'll likely see use concentrations quite low, usually 0.1-0.2%.
Overall, this is a well-tolerated ingredient that works well in formulas designed for sensitive, reactive, or post-procedure skin.
Learn more about BisabololSodium Phytate is the sodium salt of Phytic acid, a compound that plants store phosphorus in. It's the plant-derived alternative to ingredients like Disodium EDTA.
In skincare, this ingredient is a chelator that grabs onto trace metal ions like iron and copper that sneak into formulas through water/raw materials.
Those metals speed up oxidation so binding them keeps oils, fragrance, and actives from going off, stops color changes, and helps the preservative system work harder.
Survey data shows usage levels range from 0.0099%-0.5% in leave-on products, 0.025%-0.3% in rinse-off, and up to 0.05% in eye-area products. Suppliers typically recommend a range between 0.05-0.5%.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
