L'Oreal: a well-known French brand, medium to high-end, relatively expensive;

Oprey: a Sino-Japanese joint venture brand, this is the first time I have heard of it, so I don't have a cold and don't comment;

Proya: a Chinese local brand, a new brand founded in 2006, so many people answered that it was a copycat brand in 2013. Now it has been launched in 2017, becoming the first listed brand in China's skin care and cosmetics industry. We can say that it is its own brand, but don’t easily say that others are copycats. The price is relatively affordable. Proya's Hydrating Core Skin Series is very good and quite popular (suitable for a variety of skin types). I am a Proya product, so I will be more specific.

As for the effect of using the product, it varies from person to person. Each brand has its own unique features. The skin care cosmetics that suit you are the best! Just like many of us recognize people rather than brands (my friend used to use L'Oreal, and now I use Proya).

Don’t say which one is the real brand. The names are just similar. They are all registered trademarks and have brand certification marks.

Purely hand-made, personal opinion! !
