Frequently Asked Questions

What are peptides?
Made up of a short string of amino acids, peptides for skin are some of the most popular active ingredients used to target your anti-ageing concerns. Experience a surge of hydration, visibly reducing the appearance of wrinkles and fine lines upon application. With regular use, our products are specially designed to restore the appearance of aged skin for a visibly glowing complexion.
What are the potential benefits of using peptides in skincare?
Also referred to as polypeptides, peptides offer synergistic benefits to renew and restore your complexion across multiple areas: • Add deep hydration to plump skin and reduce the appearance of wrinkles. • Help protect your skin’s protective moisture barrier against pollution and UV damage. • Help make your skin look and feel smoother and more taut. • Help improve the appearance of wrinkles.
Are peptides suitable for all skin types?
Absolutely — we invest in research and development so you can enjoy elegantly blended formulas and peptides for all skin types, whether your skin edges on the dry, oily, combination or mature side.
When and how should I incorporate peptides into my skincare routine?
Start incorporating peptides into your skincare routine as early as your mid-20s to maintain healthy-looking skin and delay visible signs of ageing. To use peptides effectively, apply them after your cleanser and toner. Layer your peptide serum across your entire face, neck and décolletage and seal in its skin-renewing benefits with a moisturiser, oil or SPF.
Can I use peptides with other skincare actives?
Yes, you can use peptides alongside other skincare actives, such as retinol, niacinamide and hyaluronic acid. Peptides work particularly well with hydrating ingredients like hyaluronic acid and soothing ingredients like niacinamide. To enhance skin recovery and support, apply retinol first, followed by a peptide serum. Always perform a patch test when introducing new products.
How should I layer my skincare when using peptides?
To get the most out of your peptide-based products, apply them after cleansing and toning but before creams and oils. During the day, a typical sequence might be a cleanser, toner, peptide serum, moisturiser and SPF. In the evening, you can follow up with a richer cream or oil to lock in the peptides.
How long does it take to see results from using peptides on my skin?
You may see noticeable results from peptides within 2 to 4 weeks of consistent use, seeing improvements in skin texture and hydration. However, for more significant benefits, such as reducing fine lines and wrinkles, it may take up to 12 weeks.
Are peptides suitable for pregnant and breastfeeding women?
Peptides are generally safe for use during pregnancy and breastfeeding. However, consult your healthcare provider before adding any new skincare products to your routine, especially if they contain other active ingredients like retinol.
What precautions should I keep in mind when using peptides on my skin?
While peptides are gentle and suitable for most skin types, introduce them gradually into your routine, particularly when using them with other actives like retinol or acids. Always perform a patch test first, and if irritation occurs, reduce usage or consult a dermatologist. Don’t forget to apply SPF during the day to protect your skin, as peptides work to repair and renew.
What peptides do your products contain?
While peptides vary by product, we carefully create each formula to provide the optimal concentration for your skin. Our Oxy-R Peptides serum features Acetyl Glycyl Beta-Alanine — a brightening solution — to block the transport of melanin to the skin cells. It also contains Tetrapeptide-30 to minimise the production of tyrosinase, which helps reduce the look of skin hyperpigmentation and improve the appearance of tone and texture. Our Bakuchiol Peptides formula is a gentle alternative to Vitamin A and contains skin-penetrating Brightening Peptide Precursors that block the overproduction of pigment in the skin. These help lessen the visibility of hyperpigmentation while resulting in a brighter, more even complexion.
How should I store peptide-based products?
Store peptide-based skincare products in a cool, dry place away from direct sunlight to maintain their potency and avoid exposure to extreme temperatures. Some peptide serums may benefit from refrigeration, but always check the product's storage instructions.
What other products can I find at Medik8?
Beyond peptides, Medik8 offers a wide range of efficacious skincare products that target various concerns, including vitamin C serums, retinol treatments, sunscreens and more. We use high-quality ingredients that support your skin’s health and vitality at every step of your skincare journey.
