Using aloe vera gel can be a gentle and soothing option for your skin, especially since you have oily, acne-prone skin with pigmentation and open pores. Here are some key points to consider:

• Aloe Vera Benefits: It has natural anti-inflammatory and moisturizing properties that can help calm irritated skin and may reduce redness associated with acne.

• Oily and Acne-Prone Skin: Aloe vera is lightweight and non-comedogenic, meaning it usually doesn't clog pores, which is good for oily and acne-prone skin.

• Pigmentation and Black Spots: While aloe vera may help soothe the skin, it is not a strong treatment for pigmentation or black spots. For these concerns, you might need products with ingredients like niacinamide or consult a dermatologist.

• Patch Test: Before applying aloe vera gel all over your face, do a patch test on a small skin area to ensure you don’t have any sensitivity or allergic reaction.

• Additional Care: Maintaining a gentle skincare routine with cleansing, moisturizing, and sun protection is important. Avoid harsh scrubs or over-washing, which can worsen oiliness and irritation.

If your skin issues persist or worsen, it’s best to see a dermatologist who can recommend treatments tailored to your skin type and concerns. Overall, aloe vera gel can be a safe and soothing addition to your skincare, but it’s not a complete solution for all your skin concerns.
