Collection: Skin Care Products Containing Multi-Peptides

What is Multi Peptide and Why Is It Used in Skincare?

Peptides are short protein chains formed by connecting two or more amino acids. These molecules, which are the building blocks of proteins, act as "messengers" in the skin — they send signals telling cells what to do. Produce collagen, synthesize elastin, relax muscles, repair damage — all these instructions are transmitted via peptides.

The concept of "Multi Peptide" refers to combining multiple peptides of different types and with different functions into a single formula. While a single peptide targets only one skin issue, a multi-peptide formulation intervenes in multiple signs of aging — wrinkles, loss of elasticity, sagging, dullness, collagen degradation — simultaneously. This approach is the gold standard of modern anti-aging skincare.

Types of Peptides: Each Peptide Has a Different Function in the Skin

Peptides used in skincare are divided into four main categories based on their mechanisms of action:

1. Signal Peptides — "Collagen Builders"

They send a signal to fibroblast cells to "produce more collagen and elastin." They provide firmness, plumpness, and elasticity by strengthening the skin's structural skeleton. Signal peptides used in The NewLab formulations:

Matrixyl 3000 (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7): One of the most powerful signal peptides. It works through the synergy of two different peptides — Palmitoyl Tripeptide-1 directly stimulates collagen synthesis, while Palmitoyl Tetrapeptide-7 slows down collagen degradation by reducing inflammation. In clinical studies, a significant reduction in wrinkle depth and an increase in skin thickness have been observed.

Copper Peptide / GHK-Cu: A powerful signal peptide found naturally in the body, formed by the binding of three amino acids with a copper ion. It supports collagen and elastin synthesis, paves the way for new collagen formation by accelerating the breakdown of damaged collagen, and exhibits strong antioxidant and anti-inflammatory effects. It is present at a 1% concentration in The NewLab's Multi Peptide Serum. → Skincare Products Containing Copper Peptide

2. Neurotransmitter Inhibitor Peptides — "Muscle Relaxers"

They reduce expression wrinkles (forehead lines, crow's feet, lip lines) by preventing excessive contraction of facial muscles. Also known as a "topical Botox alternative" — they provide a muscle-relaxing effect without injections.

Argireline (Acetyl Hexapeptide-8): One of the most researched neurotransmitter inhibitor peptides. It partially prevents the formation of the SNARE complex at the neuromuscular junction, thereby reducing the intensity of muscle contraction. Result: less contraction = fewer expression wrinkles. It is present in an effective dose in The NewLab's Multi Peptide Serum. → Skincare Products Containing Argireline

Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate): A synthetic peptide developed by being inspired by the venom mechanism of the Temple Viper (Waglerin-1). It provides muscle relaxation by binding to muscle nerve endings. It has a similar mechanism to Argireline but binds to different receptors — when used together, they show a complementary effect.

3. Carrier Peptides — "Mineral Transporters"

They support enzymatic processes by transporting trace elements like copper, zinc, and manganese to the deeper layers of the skin.

GHK-Cu (Copper Peptide): Acts in a dual role as both a signal peptide and a carrier peptide. By transporting the copper ion to the deeper layers of the skin, it supports the activation of antioxidant enzymes such as superoxide dismutase (SOD). This dual mechanism makes GHK-Cu one of the most versatile peptides in skincare.

4. Enzyme Inhibitor Peptides — "Degradation Blockers"

They help protect existing structural proteins by inhibiting the activity of enzymes (MMP — matrix metalloproteinases) that break down collagen and elastin. While producing new collagen, protecting the old one: a dual-sided strategy.

The NewLab Skincare Products Containing Multi Peptide

Advanced Anti-Aging Skincare Serum (Multi Peptide + 1% Copper Peptide)

The NewLab's most comprehensive anti-aging serum combines 4 powerful peptides from 4 different categories in a single formula to intervene in multiple signs of aging simultaneously:

Matrixyl 3000 → Stimulates collagen synthesis and slows down collagen degradation (signal peptide)

Argireline → Inhibits muscle contraction to reduce expression wrinkles (neurotransmitter inhibitor)

Syn-Ake → The second muscle relaxer that complements Argireline — expands the area of effect by binding to different receptors

1% Copper Peptide (GHK-Cu) → Collagen + elastin production, antioxidant protection, and skin repair (signal + carrier peptide)

On top of these four peptides, Hymagic 4D (4 different molecular weights of hyaluronic acid) in the formulation provides multi-layered hydration, and the Moisturizing Complex keeps the skin hydrated for up to 72 hours. Lactobacillus/Radish Root Ferment Filtrate supports the skin microbiome, adding barrier strengthening and anti-inflammatory effects.

The serum's natural blue color comes from the copper ion in the Copper Peptide (GHK-Cu) — no artificial colorants are used.

Active Ingredients: Matrixyl 3000, Argireline, Syn-Ake, 1% Copper Peptide (GHK-Cu), Hymagic 4D, Moisturizing Complex, Amino Acid Complex

Multi Peptide vs. Retinol: Which is More Effective?

These two anti-aging actives work through completely different mechanisms and complement each other when used together:

Multi Peptide: Directly stimulates collagen synthesis (signal), prevents muscle contraction (neurotransmitter), transports copper (carrier), slows down collagen degradation (enzyme inhibitor). A "building" approach — targets new protein production and the protection of existing proteins. Generally well-tolerated even by sensitive skin, does not create sun sensitivity, and can be used during pregnancy.

Retinol: Accelerates cell turnover, alters gene expression. A "renewing" approach — speeds up the shedding of old cells and the production of new ones. Carries the risk of dryness, sensitivity, and purging; sun sensitivity may increase, and it cannot be used during pregnancy.

Strategy for using together: Multi peptide serum in the morning and retinol serum in the evening is an ideal distribution. Alternatively, you can maximize the anti-aging effect while protecting the barrier by using retinol 2-3 nights a week and multi peptide every night. The NewLab's Multi Peptide Serum + Retinol Serum form a powerful anti-aging duo.

Active Not to Use with Multi Peptide: Vitamin C

Best Combinations: Which Actives Can Multi Peptide Be Used With?

Multi Peptide + Hyaluronic Acid: A perfect duo. While HA provides deep hydration and plumping, peptides support structural protein synthesis. Since The NewLab's Multi Peptide Serum already contains Hymagic 4D, this synergy is offered ready in the formula.

Multi Peptide + Niacinamide: While niacinamide provides barrier strengthening, sebum control, and blemish lightening, peptides provide structural anti-aging support. pH-compatible, can be used together without issues.

Multi Peptide + Retinol: Use at different times (peptide in the morning, retinol in the evening) or on different days. Full-spectrum anti-aging care from two different anti-aging mechanisms.

Multi Peptide + Squalane: Squalane works great as a locking layer over the peptide serum. It supports the absorption of peptides and extends the hydration effect.

Multi Peptide + Collagen: While peptides support collagen production from within, topical collagen provides hydration and surface smoothing from the outside. A dual collagen strategy from within and outside.

Which Skin Types Is Multi Peptide Suitable For?

Mature Skin (35+): The area where multi peptide serums are strongest. Provides a multi-front intervention for signs of aging such as collagen loss, decreased elasticity, wrinkles, and sagging.

Early Signs of Aging (25-35): Ideal as protective anti-aging when the first fine lines, expression wrinkles, and changes in skin tone begin. It is the most effective preventive active in the period when retinol is not yet necessary.

Sensitive Skin: An excellent alternative for sensitive skin that cannot tolerate retinol. Peptides are generally very well tolerated — there is no risk of irritation, dryness, or purging.

Dry Skin: Hymagic 4D and the Moisturizing Complex in the Multi Peptide Serum provide intense hydration along with an anti-aging effect.

Oily and Combination Skin: The light, water-based texture of the serum does not weigh down oily skin. Peptides do not clog pores and do not increase sebum production.

Correct Application Guide

1. Cleansing: Wash your face with a gentle cleanser.

2. Toner (optional): Prepare the skin for care with a toner.

3. Multi Peptide Serum: Take a few drops of the Multi Peptide + Copper Peptide Serum and gently spread it over your face and neck. Pay extra attention to areas where expression wrinkles are intense, such as forehead lines, around the eyes, and around the corners of the mouth.

4. Moisturizer: Lock it in with Cica Cream or your preferred moisturizer after the serum has been absorbed.

5. Sunscreen (morning): Add SPF 30+ sunscreen to your morning routine.

Usage frequency: Can be used 2 times a day, morning and evening. For first-time use, it is recommended to start 2-3 times a week and gradually transition to daily use. If you are using Vitamin C, apply Vitamin C in the morning and the peptide serum in the evening.

Frequently Asked Questions

At what age should a multi peptide serum be used?

It can be started as protective anti-aging from the age of 25. The first fine lines and expression wrinkles begin to appear at these ages. For those 35 and older, it should be one of the staple products of active anti-aging care. There is no upper age limit.

Can a multi peptide serum be used with Vitamin C?

Not simultaneously, it should be used at different times. Pure Vitamin C (L-Ascorbic Acid) works at a low pH and can disrupt the peptide structure. Additionally, there is a risk of oxidative interaction with copper peptide. Solution: Apply Vitamin C in the morning and multi peptide in the evening.

Can a multi peptide serum be used during pregnancy?

Yes. Peptides are not actives to be avoided during pregnancy like retinol. They can be safely used during pregnancy and preferred as an alternative anti-aging active instead of retinol.

Is the blue color of the multi peptide serum normal?

Yes, it is completely natural. The blue color comes from the copper ion of the Copper Peptide (GHK-Cu) in the formula. No artificial colorants or dyes are used. This blue tone, which is the natural color of the copper ion, is an indicator of the product's purity and active content.

Can a multi peptide serum be used with retinol?

Yes. It can be used at different times or on different days. Peptide in the morning, retinol in the evening is an ideal distribution. Alternatively, you can use retinol 2-3 nights a week and peptides every night. A double anti-aging effect is obtained from two different mechanisms.

Can a multi peptide serum be used around the eyes?

Yes. Argireline and Syn-Ake in the Multi Peptide Serum specifically target the crow's feet (wrinkle) area around the eyes. It can be applied gently around the eyes. The NewLab's eye care products also contain peptide formulations.

What is the difference between a multi peptide serum and a Copper Peptide serum?

Multi Peptide Serum combines 4 different peptides (Matrixyl 3000, Argireline, Syn-Ake, Copper Peptide) in a single formula to address multiple signs of aging simultaneously—providing comprehensive anti-aging. Anti-Wrinkle Argireline + Copper Peptide Serum, on the other hand, is a targeted solution that focuses on expression lines with its high concentration of 10% Argireline. For general anti-aging, the Multi Peptide serum can be chosen, while the Argireline serum is preferred for prominent expression lines.

How long does it take to see results from peptide serums?

Peptides are "slow but steady" actives. The initial moisturizing effect is felt immediately, the muscle-relaxing effect begins in 2-4 weeks, and the collagen synthesis effect becomes visible in 4-8 weeks. Full results are achieved with 8-12 weeks of consistent use. Unlike retinol, there is no purging or adaptation period.
