Modern cosmetology has long moved beyond just creams and masks. Today, specialists have a whole range of procedures that affect the skin from the inside. One of the most important procedures is peptide injections. These injections are not just designed to hide age-related changes, but truly activate the natural rejuvenation processes. One of the key components used in such procedures is Peptides — short chains of amino acids that act as building blocks for skin cells and stimulate collagen production.
What Are Peptides and How Do They Work?
Peptides are molecules composed of amino acids connected in a chain. Essentially, they are “messengers” for cells, transmitting signals about which processes need to be activated. When the amount of peptides in the skin decreases, it starts to lose firmness, dryness appears, wrinkles form, and the complexion becomes dull.
Peptide injections help replenish this deficiency. After being introduced, the substance penetrates into the deep layers of the dermis, where it activates collagen, elastin, and hyaluronic acid production. As a result, the skin gradually becomes firmer, its tone increases, and fine lines disappear.
The main advantage of peptides is their selective action. This means that each type of peptide is aimed at a specific task: restoring cells, improving nourishment, reducing inflammation, or strengthening blood vessels.
Main Types of Peptide Injections
There are several categories of peptides used in cosmetology. They differ in their mechanisms of action and the expected effects.
The Most Popular Types:
- Signaling peptides — stimulate collagen and elastin production, accelerate tissue healing;
- Neuropeptides — act like “soft Botox,” relaxing mimic muscles and reducing the appearance of wrinkles;
- Copper peptides — strengthen blood vessel walls, improve microcirculation, and promote tissue restoration;
- Capsulated peptides — used in mesotherapy cocktails, providing a prolonged effect due to slow release of active substances.
Each of these types is selected by the cosmetologist individually, depending on the condition of the skin and the patient’s age. For example, in younger patients, signaling peptides are commonly used for aging prevention, while after the age of 35–40, the focus shifts to neuropeptides and copper peptides.
Advantages of Peptide Injections
Peptide procedures are considered one of the safest and most effective in modern cosmetology. They offer a number of advantages:
- Natural effect without radical methods;
- Gradual but lasting results;
- No long recovery period;
- Compatibility with other procedures (laser, peels, biorevitalization);
- Minimal risk of allergic reactions.
Because of these advantages, peptide injections are an excellent alternative to plastic surgeries and traditional Botox injections.
After a course of treatments, the skin becomes smoother, more hydrated, the complexion evens out, and the signs of fatigue and inflammation diminish. The results typically last from 6 to 12 months, depending on the individual’s lifestyle and skin characteristics.
Which Areas Can Be Corrected with Peptide Injections?
Peptides are versatile, so they can be used on various areas of the face and body. The most common areas for injections are:
- Forehead and glabella (frown lines) — to smooth out wrinkles;
- Under-eye area — to treat “crow’s feet” and puffiness;
- Cheeks and cheekbones — to restore firmness and elasticity;
- Neck and décolleté — to improve skin texture;
- The back of the hands — to eliminate signs of aging.
Additionally, peptides are actively used in trichology. Injections into the scalp help strengthen hair follicles and stop hair loss, which is especially important during hormonal changes or stress-related factors.
How the Procedure Works and What to Expect
Peptide injections are considered minimally invasive procedures. Before the session, the cosmetologist conducts a consultation and assesses the skin condition. Then, a composition is chosen — typically a mesococktail that combines peptides with hyaluronic acid, vitamins, and amino acids.
The procedure is performed using a very fine needle, making it nearly painless. After the injection, there may be slight swelling or redness, but they typically go away within a day. To achieve a pronounced effect, it is recommended to undergo a course of 4–6 procedures with an interval of 1–2 weeks.
After the course, the skin looks fresh, hydrated, and “rested.” Peptides continue to work for several weeks after the treatments, supporting the natural regeneration of cells.
Aftercare Recommendations Following Peptide Injections
To maintain the results of peptide injections for longer, it’s important to follow proper skincare:
- Avoid direct sunlight and use SPF cream;
- Do not visit saunas and swimming pools for 3–5 days;
- Avoid using aggressive scrubs and peels;
- Maintain hydration and a balanced diet;
It’s also beneficial to use skincare products with peptides in the composition. This will help prolong the effect and keep the skin in good condition between courses of procedures.
Peptide injections are a modern way to extend youthfulness without surgical intervention. They work at the cellular level, helping the skin restore itself. Thanks to peptide technology, cosmetology has reached a new level, where the focus is not on masking signs of aging but on activating the body’s internal resources.
