I am very grateful and happy with the doctor, since I had a 2-year problem with spots on my face which caused me low self-esteem and depression. I had previously gone to other dermatologists and they did not solve my problem, but Dr. Oswaldo gave me an accurate treatment and my face is now clear. I am very, very happy.

About Medical Conditions & Treatments
Is Aquaphor good for eczema?
Yes, Aquaphor is excellent for eczema management. It's a petroleum-based healing ointment that creates a protective barrier on the skin, helping to lock in moisture and prevent water loss. Aquaphor is fragrance-free, hypoallergenic, and recommended by dermatologists for eczema care. It's particularly effective when applied to slightly damp skin after bathing to seal in moisture. Our dermatologists in Mexico often recommend Aquaphor as part of a comprehensive eczema treatment plan.
Can stress cause acne?
Yes, stress can significantly worsen acne through multiple pathways. Stress increases cortisol production, which can stimulate oil glands and increase inflammation. Stress also weakens the immune system, making it harder for skin to fight acne-causing bacteria. Additionally, stress often leads to poor sleep, unhealthy eating habits, and increased touching of the face. Managing stress through exercise, adequate sleep, relaxation techniques, and proper skincare can help improve acne.
