Skincare benefits

Peptides are powerhouse ingredients in skincare that help boost collagen, smooth fine lines, and give your skin that plump, youthful glow we all desire.

What exactly are Peptides?

Peptides are short chains of amino acids, which are the building blocks of proteins like collagen and elastin in the skin. These proteins provide structural support, keeping the skin firm and youthful.

Peptides act as messengers, signaling the skin to produce more collagen, elastin, and even hyaluronic acid. This helps maintain skin strength, hydration, and resilience over time.

Some peptides also help stimulate hyaluronic acid production, which binds water to the skin, keeping it hydrated and plump.

Types of Peptides in Skincare

Not all peptides are equal. Some are thoroughly researched (like Matrixyl 3000 or GHK-Cu), while others are backed only by the company selling them. Stick to peptides with a proven track record—validated by independent studies from universities or hospitals.

Think of it this way: trusting a well-researched peptide is like hiring a seasoned pro; opting for minimally studied ones is like gambling on a rookie.

Four types of anti-aging peptides

Signal Peptides - Instruct the skin to produce more collagen, elastin, and other essential proteins.

Why it works: Boosts skin structure, reducing fine lines and wrinkles.

Best in class: Matrixyl 3000 (palmitoyl tripeptides 1 & 7).

Neurotransmitter Inhibitor Peptides - Relax facial muscles to minimize expression lines (like Botox, but gentler).

Why it works: Softens wrinkles without needles.

Best in class Argireline (acetyl hexapeptide-8).

Carrier Peptides - Deliver essential trace elements like copper, which are key for collagen formation.

Why it works: Enhances skin repair and elasticity.

Best in class GHK-Cu (copper tripeptide-1).

Enzyme Inhibitor Peptides - Block enzymes that break down collagen and elastin.

Why it works: Prevents collagen degradation while boosting hydration

Best in class: Rice Peptides.

Synergy = Results

Most serums on the market contain only one or two types of peptides. But to get the best results, you need a multi-pronged approach. That’s why Peptide Squad combines all four classes in one serum. Each class addresses aging differently, giving you a holistic solution.

It’s like building a healthier lifestyle: doing yoga helps, but combining it with strength training, better nutrition, and good sleep gets you there faster. Peptides work the same way—tackling wrinkles from multiple angles delivers faster and more noticeable results.


How to Incorporate Peptides Into Your Routine

For optimal results, pair peptides with the "Vitamin ABCs" of skincare:

Vitamin A (Retinoids): Boosts cell turnover and collagen production.

Vitamin B3 (Niacinamide): Strengthens the skin barrier and reduces redness.

Vitamin C: Fights free radicals and brightens the skin.
