It is not recommended to skimp on cosmetics, as they have direct contact with the skin.
If the product is of low quality, then the harm from it may be greater than the potential benefit.
First of all, you need to evaluate the active ingredients. If you want to find a truly worthy product that will be useful and safe for the skin, then the amount of natural ingredients should be dominant.
However, experts recommend making sure you don't have an allergic reaction to the ingredients.
There may be some chemical components in the composition, and this is normal. Otherwise, the products will not be stored well and will lose their properties.
Remember that the composition is always written according to the rules. The active substances that are more numerous are listed first. Therefore, pay attention to the first 3-4 positions of the composition. They must be natural.
Sometimes, well-promoted cosmetics companies can disappoint you if you want to study the composition in detail. Sometimes it differs from what is stated in the advertisement.
Therefore, do not trust promises: just study the components included in the composition. Yes, well-known companies can guarantee safety, but some manufacturers can offer a product no worse for a more modest "reward".
