Elastin and Skin: Benefits and Cosmetic Innovation

Over time, you may begin to notice that your face looks less toned, that signs of aging emphasize its contours, and that your skin feels less firm — to the point that even your makeup seems to break down. Your skin may be losing one of its most valuable structural components: elastin.

In the world of functional cosmeceuticals, there are no miracles: there is science. Understanding how our skin is structured and which mechanisms regulate its natural aging process is the first step toward choosing the most effective treatments. So let’s take a journey through the skin’s layers to examine the role of elastin and discover how the latest biotechnological innovations are redefining the standards of firming treatments.

A journey through the skin: epidermis, dermis, and hypodermis

Before purchasing any cosmetic product, it is worth asking yourself a few questions about how our skin really works. It is not a simple covering, but a complex, dynamic organ made up of three main layers, each with specific vital functions.

The outermost layer, the one we touch and see every day, is the epidermis. It is 0.03 to 0.05 millimeters thick on the face and acts as a barrier against bacteria, pollution, and dehydration. It consists of keratinocytes, which produce keratin to strengthen its structure, and melanocytes, which are responsible for producing melanin and protecting the skin from UV rays. Keeping the epidermis intact and healthy is essential for limiting transepidermal water loss (TEWL) and preserving the skin barrier.

Immediately beneath it lies the dermis, the true engine of youthful-looking skin. This middle layer, rich in blood vessels and nerve endings, is home to fibroblasts: tireless factories responsible for producing collagen, hyaluronic acid, and elastin. When we talk about deep wrinkles, sagging, and loss of tone, we are looking at a depletion that occurs precisely here.

Deeper still lies the hypodermis, or subcutaneous tissue, composed mainly of adipose tissue that acts as an energy reserve, thermal insulator, and shock absorber. Over time, the facial fat compartments also tend to lose volume, contributing to a loss of definition in the facial oval.

Elastin and collagen: what is the difference?

The fibrous proteins found in the dermis are elastin and collagen, and they work together to keep the skin firm. They are often mentioned together, but they perform deeply different and complementary roles.

Elastin accounts for approximately 2–5% of the dermal network and is the molecule responsible for elasticity: it allows the skin to return to its original shape after being stretched or subjected to the movements of facial expressions. Collagen, on the other hand, is the framework that provides structure and strength, and makes up by far the majority of dermal proteins.

In simple terms: elastin provides flexibility and shape memory, while collagen provides support. A lack of collagen causes loss of volume, thinning, and deep furrows; a lack of elastin robs the skin of its ability to “bounce back.”

Why does skin lose its elasticity?

The natural synthesis of elastin and collagen begins to slow as early as age 25. Scientists divide the causes of this degradation into two broad categories.

• Intrinsic (chronological) aging: determined by genetics and the passage of time. Fibroblast activity naturally declines, and existing fibers begin to fragment and stiffen, losing their natural tension.
• Extrinsic (environmental) aging: external factors that accelerate the process. Exposure to UV rays stimulates the production of metalloproteinases, enzymes that degrade collagen and elastin fibers. Chronic stress, smoking, and pollution also generate free radicals, causing oxidative stress and glycation, a process that stiffens dermal proteins.

The result is skin that struggles to return to its original position, leaving room for static wrinkles and sagging along the facial oval.

Cosmetic innovation: from hydrolyzed elastin to biotechnology

Historically, the cosmetics industry has attempted to replenish lost elastin by adding it directly to products. Hydrolyzed elastin was used for a long time for its moisturizing and conditioning properties, but the native molecule is too large to penetrate the dermis: the hydrolyzed version acts mainly on the surface, retaining water and creating a protective film that provides an immediate softening effect.

Although it is a good humectant ingredient, modern cosmeceuticals have recognized that truly firming the skin requires more than applying proteins to the surface: fibroblasts must be reawakened and encouraged to produce new proteins from within. This is where the innovation of biomimetic peptides comes in: sequences of amino acids capable of crossing the skin barrier and communicating directly with dermal cells, sending signals that stimulate the synthesis of new structural fibers.

Versillin™: the peptide that reawakens the skin

At LeLang laboratories, we believe in proven efficacy and measurable results, which is why we select biotechnological actives capable of restoring the skin’s natural function. Versillin™ is one of them: a next-generation active developed for firming treatments.

Versillin™ acts on the extracellular matrix: rather than simply hydrating, it promotes the regeneration of skin tissue. According to supporting clinical data, it delivers a +106% increase in elastin synthesis — thereby restoring the skin’s ability to produce its own elastin — and up to +32% greater skin density, reorganizing the structure of the dermis.

CollagenEtic Serum: LeLang’s solution for skin remodeling

Can all this theory be contained in a single product? We tried with CollagenEtic Serum, LeLang’s first facial firming serum, designed for those who want to actively combat sagging along the facial oval and loss of density.

We did not settle for a single ingredient: we formulated a complete serum capable of creating an ideal dermal environment by combining the efficacy of Versillin™ with other patented, clinically tested actives.

• Col-Frag Remastered: a plant-based biotechnological collagen sustainably extracted from Nicotiana benthamiana, which mimics a fragment of human collagen. Studies show an increase of up to 250% in type I procollagen production in 48 hours, with a marked lifting effect and a reduction in wrinkle depth of up to 24% in 28 days.
• Gardenia Stems GX™: stem cells from Gardenia jasminoides that protect the existing collagen network, reduce collagenase activity by up to 94%, and stimulate new collagen synthesis by 33%.
• Viniderm®: a patented complex derived from grapes, rich in polyphenols, that protects mitochondrial DNA from free radicals — from the same botanical family as grapeseed oil.
• Kudzu: a powerful isoflavone that slows the loss of skin volume and supports cellular turnover.

The formula is completed by a blend of Hyaluronic Acid with different molecular weights, which provides structure and plumping hydration both on the surface and deeper within the skin. CollagenEtic Serum is 100% vegan, dermatologically tested for sensitive skin, and formulated without compromising on sustainability.

Conclusion: a mindful routine for toned skin

Aging mindfully does not mean surrendering to skin laxity, but providing the skin with the tools it needs to remain strong, elastic, and healthy over time. Incorporating biotechnological peptides such as Versillin™ into concentrated serums is the most effective way to communicate with facial skin cells.

To maximize results, remember that a serum performs at its best as part of a structured routine: apply it morning and evening to cleansed skin, followed by a nourishing cream such as Alba to seal in the actives, and never forget sun protection during the day to defend your hard-won elastin from oxidative stress.

And remember: beauty is not a miracle; it is science applied consistently. You can also find LeLang products at partner pharmacies throughout the region.
