Apply 3-4 drops to clean, dry skin. Gently press the serum into your face and neck. Follow with your moisturiser. For best results, use twice daily - morning and evening.

Yes. Peptides and retinol complement each other well. Apply retinol first, let it absorb, then follow with your peptide serum. Use this combination in your evening routine.

Yes. Peptides work well alongside vitamin C. Apply your vitamin C serum first in the morning, then follow with the peptide serum. Both ingredients support skin health through different mechanisms.

Yes. Our serums are formulated to work individually or as part of a routine. Apply the thinnest consistency first. If using multiple serums, allow each to absorb for about 30 seconds before applying the next.

Most users notice initial improvements within 2-4 weeks of consistent use. Peptides work by supporting your skin's natural processes, so significant results - such as improved firmness and reduced fine lines - typically develop over 8-12 weeks.

Store in a cool, dry place away from direct sunlight. Keep the dropper cap tightly closed. There is no need to refrigerate, but avoid exposure to extreme heat. Once opened, use within 12 months.

Peptides are short chains of amino acids that act as signalling molecules in your skin. In skincare, different peptides are used for different concerns, such as the look of fine lines, firmness and radiance. Each peptide has its own well-studied profile.

Our formulas contain no fragrances, parabens, or unnecessary fillers, making them suitable for most skin types including sensitive skin. We recommend doing a patch test before first use: apply a small amount to the inside of your wrist and wait 24 hours.

Peptides do not typically cause purging. Purging is most commonly associated with exfoliating acids and retinoids. If you experience any irritation, reduce usage to once daily and gradually increase. If irritation persists, discontinue use and consult a dermatologist.

Yes. We never test on animals. All our products are cruelty-free and comply with EU Cosmetics Regulation (EC 1223/2009), which prohibits animal testing for cosmetic products.

The complete INCI ingredient list is available on each product page and printed on every product box. You can also visit our Ingredients page for detailed information about our active ingredients and their concentrations.

While peptides are generally considered safe, we recommend consulting your doctor or midwife before introducing any new skincare products during pregnancy or breastfeeding.

Morning: Cleanser - Peptide Serum - Moisturiser - SPF
Evening: Cleanser - (Retinol, if using) - Peptide Serum - Moisturiser

It depends on your primary concern. For firmness and repair, start with our Copper Peptide GHK-Cu Serum. For fine lines and expression wrinkles, try the Acetyl Hexapeptide-8 Serum. For overall collagen support, the Matrixyl 3000 Serum is an excellent choice. Visit our product collection to compare.
