Ingredients Included in Anti-Aging Skincare

Aging skin results from both internal processes, such as genetics and reduced production of structural proteins, and external factors, such as sun exposure and lifestyle. When collagen and elastin decline, the skin develops visible signs of aging like fine lines, wrinkles, and loss of firmness. Anti-aging skincare formulations focus on ingredients that address these changes by supporting the skin’s structural integrity and renewal.

Peptides are short chains of amino acids that serve as the building blocks of proteins, including collagen and elastin, which provide skin with firmness and elasticity. When collagen degrades, it forms peptide fragments, which signal the body to produce more collagen. Many anti-aging skincare products incorporate peptides to mimic this signaling process.

There are several categories of peptides in cosmetics. Some peptides stimulate the production of collagen, elastin, and other proteins. These may support skin firmness and improve the appearance of wrinkles. Other peptides may deliver trace minerals to the skin, which are used in collagen synthesis and repair processes. The outcome of using peptide-containing skincare depends on the peptide’s type, concentration, and the ability of the formulation to deliver peptides effectively to the skin’s deeper layers.

Human growth hormone (HGH) is a protein naturally produced by the body that influences growth, cellular regeneration, and tissue repair. Some topical skincare products can contain compounds designed to mimic the effects of HGH or support its natural production in the skin. The use of actual HGH in over-the-counter cosmetic formulations is strictly regulated. Cosmetic products may rely on alternative compounds selected for their ability to interact with skin cells and support rejuvenation and renewal at the surface level.

Testosterone affects skin health in both men and women, and can influence skin thickness, oil production, and hair growth. Testosterone levels decrease with age,  and may lead to thinner, drier, and more fragile skin. These effects can often be more pronounced in women after menopause.

Some formulations may use plant-based compounds (phytoestrogens) that can mimic some of testosterone’s effects. Other substances that interact with skin receptors in this way are also used.  The intention behind these products is to address skin changes linked to hormonal decline. This can include a loss of density and reduced moisture. Such ingredients may also support improved skin texture and hydration as part of a topical regimen. Use of these alternative actives is based on their capacity to interact with the skin’s hormonal receptors or related pathways, although their effectiveness can depend on individual factors and specific product formulations.

While anti-aging skincare products containing peptides and certain hormones are widely used in specific routines, they typically act on the skin’s outer layers and offer limited effects. For those seeking more comprehensive results, consulting a medical care provider is advisable, as these professionals can assess skin health and recommend advanced treatments. Professional options may involve prescription medications, chemical peels, laser therapy, microneedling, or injectable treatments such as fillers and neurotoxins, all tailored to individual needs and delivered with an emphasis on both safety and effectiveness.
