Niacinamide (or vitamin B3) is a multipurpose ingredient that balances oiliness, reduces the appearance of pores, and soothes any redness or inflammation. At the same time, it strengthens the skin barrier, helps with hydration and contributes to the reduction of acne marks or discoloration. It is ideal for sensitive, oily and acne-prone skin.

In summer, the skin needs light textures, fewer layers and high sun protection. Prefer gel cleansers, serums instead of heavy creams, and products with a matte effect. On the contrary, in winter you need rich creams, enhanced hydration and products that protect against cold air and dryness without forgetting your sunscreen.

The serum has a lighter, watery texture and is full of active ingredients, it works like an "injectable dose" of care. The cream locks in moisture and nourishes the skin. To get the maximum effect, use serum first and then cream, you don't have to choose, they combine perfectly!

Cleansing twice a day, serum with niacinamide for sebum regulation, light oil-free moisturizer, and sunscreen with a matte texture. Avoid heavy creams and products with oils. 1-2 times a week, also apply a cleansing mask or a mild peeling to avoid clogged pores.

Layering in skincare is done from the thinnest to the thickest. Start with cleansing, continue with toner (if using), then comes the serum, then the cream and finally the sunscreen. In the evening, the last step is the moisturizing product. Don't forget: let each layer absorb 30-60 seconds before moving on to the next.
