SKIN AGING

The skin-aging process involves multiple intrinsic and extrinsic factors. Intrinsic aging is related to the passage of time: our skin cells slow down their activity and their ability to renew themselves diminishes; both these cells and the structures that sustain them then experience a process of deterioration that leads to chronic skin aging.

Extrinsic damage, caused by environmental stress factors and sun exposure, accelerates cell deterioration, causing premature aging or photoaging.
This multifactorial process causes visible alterations to the skin, decreasing firmness and elasticity as wrinkles, lines, and dark spots appear, while skin brightness diminishes.

Skin firmness and elasticity are mainly determined within the dermis, where support elements such as collagen and elastin can be found, as well as other components such as hyaluronic acid, which provides volume and density.

As skin ages, or is damaged by UV radiation, its capacity to renew itself is diminished. Stem cells, which are responsible for new skin cell production, decrease and their activity slows down. The fibroblasts, responsible for synthesizing the fundamental components of the dermis, are similarly affected. The result of this is fewer skin support structures available to help maintain skin firmness and elasticity.

Fine lines and wrinkles begin to appear on the skin’s surface when skin thickness and resistance start to decrease.

Fine lines and wrinkles are also caused by alterations in the epidermis, when keratinocyte renewal slows down and the skin’s barrier function diminishes. This results in the skin becoming rougher, drier, and more sensitive. Stem cells also play an important role in the production of well-formed young cells.

Loss of firmness

Skin firmness and elasticity are mainly determined within the dermis, where support elements such as collagen and elastin can be found, as well as other components such as hyaluronic acid, which provides volume and density.

As skin ages, or is damaged by UV radiation, its capacity to renew itself is diminished. Stem cells, which are responsible for new skin cell production, decrease and their activity slows down. The fibroblasts, responsible for synthesizing the fundamental components of the dermis, are similarly affected. Because of all this, fewer skin support structures are available to help maintain skin firmness and elasticity.

Loss of brightness and appearance of dark spots

Hyperpigmentation, or dark spots, is caused by the excessive production of melanin in the skin.

Melanin is important because it protects the skin from damage caused by UVA/UVB radiation. Nevertheless, sun exposure, free radicals, skin sensitivity, and inflammation can lead to excess melanin production and, over time, the appearance of dark spots, dull skin tone, and an uneven complexion.

Sun protection and antioxidants can aid in reducing hyperpigmentation as well as preventing its appearance.

Wrinkles and fine lines

Fine lines and wrinkles begin to appear on the skin’s surface when skin thickness and resistance start to decrease.

Fine lines and wrinkles are also caused by alterations in the epidermis, when keratinocyte renewal slows down, and the skin’s barrier function diminishes. This results in the skin becoming rougher, drier, and more sensitive. Stem cells also play an important role in the production healthy young cells.
