The present invention relates to gel cream anti-aging cosmetic compositions in the form of an oil-in-water emulsion comprising sensory ingredients that are suitable for the complete treatment of the skin and also provide specific benefits for day and night care, which complement each other.

An oral care composition with retinoid compound, amino acid, and/or olive oil. An oral care composition with retinoid compound, a pentapeptide, such as palmitoyl KTTKS [SEQ ID NO. 2], and/or an olive oil. Methods of preventing gingival recession, stopping gingival recession, reversing gingival recession, decrease gum recession, increase gingival barrier protection, promoting collagen synthesis, promoting extracellular matrix synthesis, increasing gum resilience, increasing epidermal thickness and/or promoting fibrillin synthesis, in an oral cavity of an animal by contacting the oral care compositions with at least one surface of the oral cavity.

A composition including an aqueous hair perm formulation, the aqueous hair perm formulation including an emulsion. The emulsion includes an active agent capable of reducing disulfide cysteine bond linkages in hair, an emulsifying agent, and an oil agent. A method, including producing a permanent hair wave or texture. Producing the permanent hair wave or texture includes providing a composition including an aqueous hair perm formulation, the aqueous hair perm formulation including an emulsion. The emulsion includes an active agent capable of reducing disulfide cysteine bond linkages in hair, an emulsifying agent, and an oil agent. Producing the permanent hair wave or texture also includes applying the aqueous hair perm formulation to a subject's hair.
