When it comes to hydration, L 'Oré al's hydration is better. Although Kanshu's main function is to replenish water, compared with L 'Oreal, its product development is not particularly mature. L 'Oré al is a well-known skin care brand with higher strength in all aspects. It's a time-honored brand. In contrast, Kans has a shorter time and needs to be improved in some aspects.
Although Kans has been emphasizing the skin hydration bomb, it is still at a certain disadvantage compared with the well-developed L 'Oreal. L 'Oré al has developed many products with hydrating effect, and launched a hydrating beauty suit. At the same time, it has a good reputation and mass base, and has reached a mature level in research and development. So when it comes to hydration, Kans' hydration is really worse than L 'Oreal's. But for Kans, L 'Oreal also has its own shortcomings, that is, L 'Oreal is more expensive, while Kans is more cost-effective and more affordable, so it is also deeply loved by everyone.
In a word, every cosmetic has its own advantages and characteristics. I suggest that you must choose formal channels when buying, and never buy fakes.
