Facial blemishes: The best active ingredients and skincare routines to eliminate them.

Dark spots on the face, post-acne marks, or sun-induced discoloration: hyperpigmentation is one of the most common skin problems and can become a source of discomfort.

The good news? There's no need to give up.

Korean and Japanese skincare products offer effective and well-tolerated active ingredients that, when used consistently, help lighten blemishes and prevent new discolorations.

In this article, we'll discover together what the key ingredients are, how they work, and which products to use for a truly effective routine.

What is hyperpigmentation and why do spots appear?

Skin blemishes are the result of excessive or irregular production of melanin, the pigment that gives skin its color.
The most common causes are:

• Sun exposure without adequate protection.
• Post-acne : dark marks that remain after pimples or inflammation.
• Hormonal changes (pregnancy, birth control pills).
• Skin aging .

Prevention always starts with a basic rule: never without SPF .

What are the most effective active ingredients against blemishes?
