From birth, various processes take place in the body. When it comes to loss of 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 cleaning your face for decades. However, there are only a few features that can visually slow the passage of time.

Retinol (Vitamin A) is an ingredient often found in facial care products to combat the signs of aging. Sunlight often causes brown spots and wrinkles on the skin (so-called photoaging), also, over time, the skin loses elasticity, thins out, and healing takes longer comparing to younger people. Studies have shown that retinol can effectively address these side effects by smoothing out deep wrinkles, stimulates collagen production and cell regeneration. 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 from the inside out. Niacin helps the body to produce 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 ceramid (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 products. Collagen is produced naturally by our body, it is responsible for the structure of bones, tendons, cartilage, skin. As we age, our body produces less of this protein, causing your skin to loose elasticity, firmness, and a fresh, youthful look. As a result, over the years, collagen enhancement is also needed from the outside. However, products 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 externally used products) can have an excellent rejuvenating effect on both the skin and the body as a whole. For example, oral collagen has been shown to improve skin moisture balance, elasticity, density (epidermal thickness), and reduce roughness over time.
