the correlations between CXCL10 levels, CRP, and acne severity scores (e.g., Global Acne Grading System) suggest that CXCL10 could serve as a biomarker of inflammation and acne severity. Understanding the relationship between CXCL10, CRP, and acne severity may offer insights into novel therapeutic strategies targeting inflammatory pathways in acne.

Cross-sectional Observational Study. using 4 groups a 3 of different acne severity and controle one . the serum cxcl10 and crp will measured in each patient to correlate with disease severity

Inclusion Criteria:

1. Patients aged 12-40 years diagnosed with acne vulgaris.
2. Both genders included.
3. Patients with mild, moderate, or severe acne severity as determined by a validated scoring system (e.g., Global Acne Grading System).
4. Patients not on systemic acne treatment (e.g., isotretinoin or antibiotics) or anti-inflammatory drugs.

Exclusion Criteria:

1. Patients with autoimmune diseases, systemic illnesses, acute infection or any other chronic inflammatory conditions that may affect CRP or CXCL10 levels.
2. Pregnant or lactating individuals.
