- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Propanediol
- Polyol solvent at 1–5%; light feel, aids solubilization, propylene glycol alternative
- Panthenol
- Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

- Hydrolyzed Hyaluronic Acid
- Low-MW humectant with superior penetration vs high-MW; 0.1-0.5% typical, hygroscopic, store dry to prevent clumping.
- Hydrolyzed Sodium Hyaluronate
- Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.
- Acacia Senegal Gum
- Natural film-former and fragrance agent; used for viscosity or film, check purity for allergens
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Tetrasodium Glutamate Diacetate
