Forehead acne is primarily caused by the blockage of pores due to excess oil (sebum) production, dead skin cells, and bacteria. The forehead, being part of the T-zone, tends to be oilier, which makes it more prone to clogged pores and breakouts

. Key causes of forehead acne include:

• Excess oil and clogged pores: Overproduction of sebum mixes with dead skin cells, blocking pores and leading to acne

• Hormonal changes: Fluctuations during puberty, menstruation, pregnancy, or conditions like polycystic ovary syndrome (PCOS) increase oil production, triggering acne

• Hair and skin products: Hair gels, oils, sprays, and some cosmetics can clog pores on the forehead, causing "pomade acne"

• Friction and sweat: Wearing helmets, hats, or headbands traps sweat and bacteria on the forehead, promoting breakouts

• Stress: Stress increases cortisol, a hormone that stimulates oil production and inflammation, worsening acne

• Diet: High-glycemic foods and diets rich in sugar and fat may contribute to acne, though the link is still being studied

• Genetics: A family history of acne can increase susceptibility due to inherited skin characteristics

Other factors like dandruff or fungal infections can also contribute to forehead bumps that resemble acne

. In summary, forehead acne results from a combination of excess oil, clogged pores, bacteria, hormonal influences, lifestyle factors, and sometimes genetic predisposition
