PEPTIDES
The most peaceful and friendly components of cosmetics for mature skin which increase production of collagen, restore the skin after damage and even able to work as muscle relaxants (thanks to which it is possible to prevent facial wrinkles) – their species are numerous. Despite the complexity of formulations, the remedies with peptides are practically incapable to lead to unexpected irritations, inflammations, and allergic reactions. They also work well with many active ingredients without losing effectiveness.
Peptides are not recommended to be used simultaneously with AHA-acids – for their work acid pH is undesirable, and peeling is better done in advance. But in combination with the ingredients shown to the sensitive skin, the peptides will be good: they penetrate deeply into the skin and can provide access to other substances. With the help of serum with peptides, you can try, for example, to increase the effectiveness of agents with niacinamide, moisturizing ingredients, vitamin C.
