FAQs

The Isabella Peptide Serum is a high-performance, multi-peptide anti-ageing serum formulated to visibly smooth, firm, and refine the skin over time. Powered by clinically studied peptide technology, it works to support your skin's natural collagen and elastin production, the structural proteins responsible for a firm, youthful complexion. With continued use, skin appears stronger, more even in tone, and delivers the luminous, glass-like finish the formula is known for.

The serum is built around a trio of clinically studied peptides, supported by a curated complex of brightening and soothing botanicals:

• Palmitoyl Tripeptide-38: Stimulates 6 key skin components to target deep wrinkles at their source.
• Palmitoyl Tripeptide-1 & Tetrapeptide-7: Boosts collagen and elastin synthesis to firm and smooth skin texture.
• Centella Asiatica (Gotu Kola): Supports collagen production while calming inflammation for a balanced, resilient complexion.
• Bearberry Extract: A brightening antioxidant that helps clarify uneven skin tone.
• Kakadu Plum: One of nature's richest sources of Vitamin C, delivering a brightening and repair boost.
• Licorice Extract: Soothes and evens tone with antioxidant properties.
• Gotu Kola Extract: A skin-healing botanical that supports overall skin recovery.

The Isabella Peptide Serum is formulated for all skin types, including dry, oily, combination, and normal skin. Peptides are widely regarded as one of the most universally tolerated classes of skincare actives, making this serum a strong option for those who may find stronger acids or retinoids too intense. As with any active serum, a patch test is recommended before first use.

Yes. The Isabella Peptide Serum is vegan friendly and proudly made in Australia. We are committed to thoughtful formulation that respects both skin and values.

The serum contains a subtle, natural botanical scent derived from Lemon Myrtle Oil, Jasmine Flower Extract, and Bergamot Fruit Oil. These are naturally derived aromatic ingredients, not synthetic fragrance. If you have a diagnosed fragrance sensitivity, we recommend performing a patch test prior to use or consulting with your skin professional.

Apply 1-2 pumps to clean, dry skin. Using your fingertips, gently massage the serum into the face and neck in upward, circular motions until fully absorbed. Follow with your preferred moisturiser. The serum is suitable for use in the morning, evening, or both.

Yes. Unlike some actives that are restricted to evening use, peptides are stable and non-photosensitising, making the Isabella Peptide Serum suitable for both AM and PM routines. For morning use, we recommend following with a broad-spectrum SPF as part of a complete anti-ageing approach.

Each bottle contains 30mL. Using 1-2 pumps once daily, a bottle typically lasts approximately 1-2 months. The product is best used within 12 months of opening. Store below 25 degrees Celsius and away from direct sunlight to maintain efficacy.

Absolutely. The Isabella Peptide Serum is designed to integrate seamlessly into an existing routine. Apply it after cleansing and any toning steps, before your moisturiser and SPF. Peptides pair well with most other actives, including hyaluronic acid, niacinamide, and antioxidant-rich serums.

Yes. Peptides are compatible with both retinol and vitamin C, and can actually complement them well. Peptides support structural rebuilding while retinol promotes cell turnover and vitamin C brightens and protects. If layering multiple actives, apply thinnest-to-thickest texture and allow each product to absorb fully. If you are new to combining actives, introducing one product at a time is always a smart approach.

Skincare works on the skin's own renewal timeline. Many users notice an immediate improvement in hydration and skin texture from first application. More significant changes, such as reduced fine lines, improved firmness, and a more even, radiant complexion, are typically visible with 4-8 weeks of consistent daily use. As with all active skincare, results deepen with continued use over time.

With consistent use, you can expect:

• A visible reduction in the appearance of fine lines and wrinkles
• Firmer, more lifted-looking skin
• A smoother, more refined skin texture
• A brighter, more even skin tone
• An overall luminous, glass-like finish

Results will vary depending on individual skin type, age, lifestyle, and consistency of use.

Peptides are among the most skin-friendly actives available and are generally very well tolerated, including by reactive or sensitised skin. The formula also contains Centella Asiatica and Licorice Root, both known for their calming and soothing properties. As with any new skincare product, we recommend performing a patch test on the inner arm before applying to the face, and discontinuing use if any irritation occurs.

While the Isabella Peptide Serum is formulated with skin safety in mind, we always recommend consulting your healthcare provider or dermatologist before introducing any new skincare product during pregnancy or while breastfeeding. Your practitioner is best placed to advise based on your individual circumstances.

Peptides are an excellent preventative as well as a corrective ingredient. From your mid-20s onwards, the skin's natural collagen production begins to slow, making this an ideal time to begin supporting it. Those in their 30s, 40s, and beyond will often notice the most visible corrective results. There is no upper age limit; peptides benefit skin at every stage.
