My own skin tone improvement know-how

It is consistent hydration and UV protection.

When my skin is dry, it feels like it looks dull overall, so I use moisturizing products thoroughly, and I always apply sunscreen when going out, regardless of the season.

I am also trying to manage my skin condition by paying attention to getting enough sleep and drinking water.

I feel that it is most important to consistently use a product that suits your skin well, rather than using multiple irritating products.
