My worst cosmetic product is Luminis All-in-One Serum.

Luminis All-in-One Serum is my worst cosmetic product.

The serum has almost no effect and causes a sensitive reaction on the skin, so even with continuous use...

My skin hasn't improved. I tend to consider the scent quite a bit when I buy cosmetics.

It was fine at first, but as time went on, I didn't like the scent either.

The price-to-performance ratio is very disappointing.

If it doesn't function properly despite the considerable price...

I think it's actually better not to use it...
