Peptides in Skincare: A Product Development Guide for Beauty Brands

Peptides are widely used in skincare product development, particularly in products positioned around firmness, skin conditioning and age-related skincare concerns.

For brands, however, the important question is not simply:

“Are peptides effective?”

A better product-development question is:

How should a peptide-based product be designed around the target consumer, formulation and market?

This guide looks at peptides from a B2B product-development perspective.

What Are Peptides?

Peptides are chains of amino acids.

In cosmetic formulation, different peptide materials can be selected for different formulation concepts and product positioning.

Peptides are often included in products designed around:

• Firming-focused care
• Skin conditioning
• Smooth-looking skin
• Antioxidant support
• Age-related skincare positioning

The final function depends on the specific peptide system and complete formulation.

Why Are Peptides Used in Skincare?

Peptides are attractive to brands because they can support differentiated product concepts.

A peptide serum, for example, can be positioned around:

The exact marketing claim should be supported by the final formulation and applicable market requirements.

Which Product Formats Can Use Peptides?

Peptides can be incorporated into different product formats.

Serums

Serums are often used for concentrated, active-focused product concepts.

Creams

Creams can combine peptide-focused positioning with moisturizing and conditioning functions.

Masks

Peptide masks can provide a treatment-oriented product format.

Eye Products

Peptide systems can also be incorporated into eye-care products depending on the formula.

The correct format depends on the product strategy. If you are deciding between two common formats, serum vs cream sets out the trade-offs.

Peptide Serum vs Peptide Cream

The same peptide concept can lead to different product experiences.

Peptide Serum

Potential positioning:

• Lightweight
• Concentrated
• Active-focused
• Layering-friendly

Peptide Cream

Potential positioning:

• Richer
• Conditioning
• Daily care
• Firming-focused

A product line may also combine the two.

Formats already in production can be reviewed in our Firming & Anti-Aging solution.

Formulation Considerations

Peptide formulation requires attention to the complete system.

Factors may include:

• Peptide type
• Concentration
• Formula pH
• Ingredient compatibility
• Stability
• Packaging
• Preservation system
• Storage conditions

The formulation team should evaluate the complete formula rather than treating the peptide as an isolated ingredient.

Packaging Considerations

Packaging can be important for active-focused formulations.

Depending on the complete formula, brands may consider:

• Airless packaging
• Pumps
• Opaque packaging
• Light-protective containers
• Controlled dispensing

The best packaging depends on the actual formula and stability requirements. Selection criteria are covered in how to choose skincare packaging.

How Brands Can Build a Peptide Product Line

A peptide product line does not need to consist of five different peptide products.

A focused portfolio could include:

Hero Product

Peptide Firming Serum

Supporting Product

Peptide Firming Cream

Treatment Product

Peptide Treatment Mask

This creates a product architecture rather than a single SKU. You can see the existing range in our product portfolio.

Peptides and Other Active Systems

Peptides may be combined with other functional systems depending on formulation objectives.

Potential combinations can include:

• Antioxidant systems
• Hydration systems
• Barrier-supporting systems
• Skin-conditioning systems

The final combination should be determined by the formulation team according to compatibility and target positioning. Barrier-supporting systems are discussed in ceramides in skincare.

What Should Brands Discuss With an OEM?

Before starting a peptide project, clarify:

• Which peptide system?
• Which product format?
• Target market?
• Desired texture?
• Target consumer?
• Target price?
• Packaging preference?
• Desired claims?

This allows the manufacturer to evaluate the product concept more effectively. A structured version of this list is provided in how to prepare a skincare product brief.

Peptides and Product Positioning

A peptide product can occupy different market positions.

Mass Market

Simple peptide-based daily care.

Premium

More sophisticated active systems and packaging.

Professional

Advanced active positioning.

DTC

Hero-product storytelling and focused product benefits.

The formulation and packaging should support the chosen positioning.

How Elythra Beauty Approaches Peptide Development

Peptide-focused formulas can be developed around:

For example, a firming-focused serum can be developed around a peptide system, specific sensory requirements and the intended target market. Existing firming concepts include Ergothioneine Firming Cream and Collagen Skinbooster Serum.

Final Takeaway

Peptides are not a product concept by themselves.

A successful peptide product needs to align:

For brands planning a peptide product, the next step is to define the desired consumer experience and commercial positioning before finalizing the formula. You can also review niacinamide and vitamin C if the product concept combines several active directions.
