Natural skin care products are becoming increasingly popular due to the harmful chemicals present in many conventional cosmetic products. However, it is important to note that not all natural ingredients are non-toxic, and the term "natural" is not well-regulated. Here are some details about natural skin care products:

Positive aspects:

• Natural skin care products are often free from harmful chemicals and synthetic ingredients.
• They can be just as effective as conventional products.
• By creating your own skincare products from scratch, you know precisely what is in them, and exactly what they are made of.

Negative aspects:

• Many natural substances that are employed in personal care products are classified as hazardous substances according to the CLP-regulation.
• Not all natural ingredients are non-toxic.

Ingredients or materials:

• Some popular natural skin care ingredients include avocado oil, chamomile, green tea, rose water, aloe water, kukui oil, and white tea extract.
• Alpha-hydroxy acids (AHA), beta hydroxy acids (salicylic acid), hydroquinone, kojic acid, and retinol are some popular skin care ingredients that are not natural.

It is important to pay attention to the ingredient list when looking for natural skin care products and ensure that the ingredients are easily identifiable. Additionally, certifications like USDA organic or COSMOS can help ensure that the natural skin care ingredients are safe for your skin type and address your specific skin problems.
