Following a skin trauma such as an acne breakout, the skin heals. This natural and beneficial process can, however, result in various types of more or less permanent marks. Tea tree essential oil is a natural ingredient recognized for its effectiveness in combating acne breakouts. But what about its action on the marks that remain after these skin eruptions?

These two occurrences can be attributed to acne breakouts but also to insect bites or even to various skin traumas. But how can we differentiate them? Let's focus.

Some skin traumas require an anti-inflammatory response that leaves behind brown marks known as post-inflammatory hyperpigmentation spots. What biological mechanism is behind this? Do these brown spots only appear after acne outbreaks, or are there other causes? Let's delve into this.

Acne blemishes and other skin lesions can sometimes leave scars behind. While some are barely noticeable, others are quite prominent. In the case of hyperpigmented scars, certain daily practices can be adopted to reduce their appearance.

PHAs (Polyhydroxy Acids) are part of the hydroxy acid family along with AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids). Considered the new generation of AHAs, they are known for their keratolytic effects, meaning they remove dead cells (a process known as desquamation), which increases cell renewal and restores radiance to the skin. How do they act on acne marks?
