Frequently Asked Questions

Do I use Niacinamide Peptides in the morning or in the evening?
Both. Niacinamide Peptides can be used after cleansing day or night.
Can I use Niacinamide Peptides alongside Liquid Peptides Advanced MP?
Absolutely. As both of these products are lightweight emulsions, the order in which you apply them shouldn’t impact things too much! However, we would still advise to always follow the thinnest to thickest rule. Niacinamide Peptides is slightly thinner in texture so, we would recommend applying that first, layering Liquid Peptides Advanced MP on top.
Do I apply Niacinamide Peptides before or after C-Tetra Luxe in the morning?
Because Niacinamide Peptides is emulsion-based and C-Tetra Luxe is oil-based, C-Tetra Luxe should be applied first.
Can I use Niacinamide Peptides while pregnant or breastfeeding?
As a cosmetics company, we are unable to provide product advice in relation to medical conditions such as pregnancy. We would recommend discussing the ingredients with your GP or midwife before use. As general guidance, this product does not contain any ingredients that we would recommend avoiding during pregnancy unless advised by your doctor.
