The copper peptide serum should be applied first, on clean, dry skin. Wait a few minutes before applying your other skincare products on top. This sequence helps optimise the penetration of the active ingredients.

No. No study shows that peptides promote hair growth. They do not act on the hair follicle and therefore have no effect on hair growth.

Both serums target the visible signs of aging and can be used together. The Multi-Active Serum combines 8% peptides with a complex of active ingredients that address radiance, hydration, and skin quality on a daily basis. It can also be used on its own as part of an anti-aging routine.

The Copper Peptide Youth Serum focuses its action on copper peptide (GHK-Cu), one of the most well-documented peptides in scientific literature for its properties on skin quality over time. It also incorporates an encapsulation technology (Cosmetic Drone) that enhances the penetration and bioavailability of the active ingredients. It is particularly well suited to intensive anti-aging routines.

Between 25 and 35 years old, the age from which natural collagen production begins to decline. Skin aging can also be accelerated by external factors such as sun exposure, pollution, stress, lack of sleep, or smoking. Starting early helps preserve skin quality over time.

No, not at the same time. Pure vitamin C (L-ascorbic acid) and copper peptides cancel each other out when applied simultaneously. Best practice is to use pure vitamin C in the morning and the copper peptide serum in the evening. However, pure vitamin C is entirely compatible with the NOOĀNCE Multi-Active Serum.

We do not recommend mixing serums directly. Our formulas are designed to ensure optimal penetration of each active ingredient. Applying them one after the other, leaving a few minutes between each, gives better results than mixing them in your hand.

It depends on the nature of the puffiness. Our eye contour care can help reduce the appearance of oedematous-type puffiness, the kind that naturally diminishes throughout the day. However, for fatty under-eye bags of anatomical origin, cosmetic treatments have no demonstrated effect. In this case, only medical or dermatological advice can point towards suitable solutions.

Yes. The Elixir is formulated to suit all skin types, including acne-prone skin. The jojoba and nigella oils it contains are documented for their tolerance on this skin type. As comedogenicity is a reaction specific to each individual, we recommend performing a skin test on a small area before full application.

As a general rule, retinol is best used in the evening, as it increases the skin's sensitivity to UV rays. However, the Intense Radiance Cream contains encapsulated retinol at a very low concentration (0.1%), a more stable and less photosensitizing form than free retinol. It can be used in the morning in combination with suitable sun protection.

The vast majority of our skincare products are vegan. The exception is our retinol-based treatments, whose formula includes a honey derivative. The full list of ingredients is available on each product page of the site.

Yes, retinol-based treatments and the Copper Peptide Youth Serum are perfectly compatible. Apply the copper peptide serum first, then the retinol cream on top, as part of your evening routine.

We recommend incorporating the Multi-Active Serum into your morning routine. It contains niacinamide and a synergy of active ingredients targeting radiance, hydration, and skin quality, without interfering with your evening retinol routine.

Yes. The Multi-Active Serum has been formulated to respect all skin types, including sensitive skin. It contains soothing active ingredients and prebiotics that help strengthen the skin barrier. For very reactive skin, we advise against retinol-based products, or recommend introducing them very gradually, in small amounts, to assess your skin's tolerance.

Both products target dark spots and can be used together. Generally, the Clarifying Treatment is better suited to red post-acne marks thanks to its azelaic acid and niacinamide content. The Radiance Cream is more focused on brown spots and hyperpigmentation. If you're unsure about your type of spots, we recommend consulting your dermatologist.

Yes. Unlike free retinol, the encapsulated retinol found in the 0.1% Radiance Cream is more stable and less likely to increase sun sensitivity. Morning application is possible, provided it is systematically combined with suitable sun protection.
