Having acne at 18 is common and often linked to hormonal changes. While acne is typically associated with puberty, it can persist or even begin later due to several factors.
Hormonal Influences
One primary reason for acne at 18, even beyond typical teenage years, is hormonal fluctuation. As noted in several sources, including a Quora discussion (https://www.quora.com/Im-18-going-on-19-Why-do-I-still-have-acne-and-how-do-I-get-rid-of-it), hormonal imbalances can trigger or exacerbate acne. These hormones stimulate sebaceous glands, leading to increased oil production and pore blockage, resulting in acne breakouts. Adult acne, as described by healthdirect (https://www.healthdirect.gov.au/acne), often has a hormonal basis and continues past the typical teenage years (around 18-20).
Genetics and Predisposition
Genetic factors also play a significant role. Research indicates a genetic predisposition for acne ([Reference 1]), meaning some individuals are more genetically susceptible to developing acne than others, regardless of age. This predisposition can lead to adult acne.
Other Contributing Factors
Beyond hormones and genetics, several other factors can contribute to acne at 18:
- Skincare and Hair Products: Ingredients in some products can clog pores and worsen acne ([Reference 1]). Carefully check labels.
- Diet: While not definitively proven for everyone, some research suggests a link between diet and acne severity.
- Stress: Stress can exacerbate existing acne or trigger new breakouts.
- Medications: Certain medications can have acne as a side effect.
Seeking Help
If your acne is severe or persistent despite trying over-the-counter treatments, consulting a dermatologist is recommended. They can diagnose the underlying cause and recommend appropriate treatments, which might include topical or oral medications (like antibiotics or retinoids, as mentioned on Quora (https://www.quora.com/Im-18-going-on-19-Why-do-I-still-have-acne-and-how-do-I-get-rid-of-it) or spironolactone (https://pubmed.ncbi.nlm.nih.gov/28155090/)).
