Learn Spanish (Latin America): Necesito un producto exfoliante y refrescante para mi piel. - I need an exfoliating and refreshing product for my skin.

They come from the -ar verbs exfoliar (to exfoliate) and refrescar (to refresh). To turn an -ar verb into an active participle (an adjective describing something that performs the action), you drop the -ar and add -ante.

Why can't I just use the gerund form and say un producto exfoliando?

In English, words ending in "-ing" can function as verbs, nouns, or adjectives. In Spanish, the gerund (ending in -ando or -iendo) is strictly used to show an action in progress, never as an adjective next to a noun. To translate an "-ing" adjective, you must use these active participles ending in -ante, -ente, or -iente.

Would these adjectives change their endings if the product was feminine, like una crema?

No, adjectives ending in -ante, -ente, and -iente do not change for gender. Whether you are describing a masculine noun like un producto or a feminine noun like una crema, the words remain exfoliante and refrescante. You only add an -s if the noun becomes plural.

Why do we use para instead of por in the phrase ?
