From birth, various processes take place in the body. When it comes to losing skin elasticity or wrinkles, you often want to stop these processes. Cosmetics marketing is constantly talking about a variety of new and magical ingredients that have been scratching your face for decades. Still, there are only a few signs that can visually slow down the passing of time.
Retinol (Vitamin A) is an ingredient often found in facial care products to combat the signs of the times. Sunlight often causes brown spots and wrinkles on the skin (so-called “photoaging”), in addition, over time, the skin loses elasticity, thins, and wound healing takes longer compared to younger people. Studies have shown that retinol can effectively address these side effects by smoothing out deep wrinkles, promoting collagen production and cell regeneration. True, retinol is a strong substance, so its safest concentration in cosmetic products is from 0.1 to 0.5 percent.

Niacin – B3 group vitamins, a nutrient that is beneficial to our body internally and externally. Niacin helps the body make keratin, a substance responsible for skin firmness and health. Perhaps the most important aspect in the fight against skin aging – niacin can help the skin form a ceramic (lipid) barrier that prevents moisture loss. Over time, this ingredient can reduce pores, wrinkles caused by the sun. In addition, B3 group vitamins help the body protect itself from harmful environmental factors: sunlight, polluted air, toxins.

Collagen is often a miraculous ingredient in cosmetic rejuvenating cosmetics. Collagen is produced naturally by our body, it is responsible for the structure of bones, tendons, cartilage, skin. True, with age, the body produces less and less of this protein, as a result of which the elasticity and firmness of the skin disappears, and a fresh, youthful appearance is lost. As a result, over the years, “collagen enhancement” is also needed from the outside. True, externally applied agents with collagen only affect the upper layer of the skin (epidermis), but its molecules are simply too large to penetrate the dermis (the layer of skin under the epidermis where most collagen is produced). On the other hand, oral collagen supplements included in the daily routine (or combined with external agents) can have an excellent rejuvenating effect on both the skin and the body as a whole.
