08 How to choose the right Peptide

What Are Peptides?

Peptides are short chains of amino acids, which are the building blocks of proteins. They play a crucial role in various biological functions, including cell signalling, collagen production, and muscle repair. Peptides are commonly used in skincare, health supplements, and medical treatments due to their ability to target specific processes in the body.

In skincare, peptides help boost collagen and elastin, making them a popular anti-ageing ingredient. In supplements, they are used to support muscle growth, recovery, and overall health.

The Benefits of Peptides

For the Skin:

Stimulates Collagen Production: Peptides help maintain skin elasticity, reducing fine lines and wrinkles.
Improves Skin Barrier: Strengthens the skin’s natural barrier, preventing moisture loss and environmental damage.
Reduces Inflammation: Helps calm redness, irritation, and sensitivity.
Enhances Hydration: Some peptides improve water retention, keeping the skin plump and hydrated.
Boosts Wound Healing: Peptides accelerate skin repair, making them beneficial for acne scars and other skin damage.

For the Body:

Supports Muscle Growth & Recovery: Peptides like creatine and BPC-157 aid in muscle repair and athletic performance.
Improves Joint & Bone Health: Some peptides promote cartilage repair, reducing joint pain.
Enhances Fat Metabolism: Certain peptides support weight loss by improving metabolic functions.
Boosts Immune Function: Some peptides help regulate immune responses and overall wellness.

Who Should Use Peptides?

Peptides are suitable for a wide range of individuals, including:

Those looking to prevent or reduce signs of ageing (wrinkles, sagging, dullness)
People with dry or damaged skin who need hydration and repair
Athletes and fitness enthusiasts seeking muscle recovery and performance benefits
Individuals with joint pain or slow wound healing
Anyone exposed to environmental stressors like pollution and UV damage

Since peptides are naturally occurring, they are generally well-tolerated and safe for most people.

How to Use Peptides & How Often to Apply Them

Topical Use in Skincare:

Common Forms: Found in serums, creams, and eye treatments.
How Often to Use: Can be applied once or twice daily, depending on the product.
Application Order: Apply peptide serums after cleansing and before heavier creams.

Supplement Use:

Common Forms: Capsules, powders, or injections (for medical peptides).
How Often to Take: Dosage depends on the type of peptide and intended use. Some peptides, like collagen supplements, are taken daily, while others are used periodically.
Consult a Doctor: Especially for injectable or high-dose peptide supplements.

Topical vs. Supplement Use: Which One is Better?

Aspect	Topical Peptides	Peptide Supplements
Purpose	Improves skin health (collagen boost, hydration)	Supports muscle growth, weight loss, and internal repair
Speed of Results	Visible skin improvements in 4-8 weeks	Systemic benefits over time
Best For	Anti-ageing, hydration, skin repair	Fitness, metabolism, immune function
Side Effects	Minimal, rare irritation	Possible digestive issues or allergic reactions

For skincare concerns, topical peptides are most effective. For overall body benefits, supplements may be a better option.

Mixing Peptides with Other Skincare Ingredients

Peptides are highly versatile and work well with most ingredients:

Compatible Combinations:

Hyaluronic Acid: Boosts hydration and improves peptide absorption.
Vitamin C: Enhances collagen production for firmer skin.
Niacinamide: Strengthens the skin barrier and reduces inflammation.
Ceramides: Helps lock in moisture for improved skin elasticity.

Ingredients to Avoid with Peptides:

Strong Exfoliants (AHAs/BHAs): High concentrations may break down peptides, reducing their effectiveness.
Retinoids: While not necessarily harmful, using peptides and retinoids together may cause irritation in sensitive skin. If using both, apply peptides in the morning and retinoids at night.

Potential Side Effects of Peptides

Topical Peptides:

Generally well-tolerated with minimal side effects.
In rare cases, they may cause mild irritation or allergic reactions.

Peptide Supplements:

Digestive Issues: Some people experience bloating, nausea, or diarrhoea.
Allergic Reactions: Uncommon but possible. Always check ingredient lists.
Hormonal Effects: Certain peptides (like growth hormone peptides) may impact hormone levels and should be used under medical supervision.

Tip: Always start with a patch test for skincare peptides and consult a healthcare provider before taking peptide supplements.

How to Choose the Right Peptide for Your Needs

For Anti-Aging & Skincare: Matrixyl, Copper Peptides, Argireline.
For Muscle Growth & Recovery: CJC-1295, Ipamorelin, BPC-157.
For Brain Function & Focus: Semax, Selank.
For Immune Support: Thymosin Alpha-1, LL-37.
For Weight Loss: AOD-9604, MOTS-c.

Peptides are powerful, multi-functional compounds that benefit both skin and overall health. Whether applied topically for anti-ageing and hydration or taken as supplements for muscle growth and recovery, they offer a range of benefits with minimal side effects.

For skincare, peptide serums and creams can be used daily for long-term improvements. For health and fitness, peptide supplements should be taken under proper guidance.
