Dr. Claudia Rios diagnoses and treats a wide range of skin, hair, and nail conditions, including:
Skin Cancers, Precancerous Lesions & Benign Growths
- Melanoma: The most serious type of skin cancer, developing in melanocytes. Early detection is crucial. Look for asymmetry, irregular borders, color variation, diameter >6mm, and evolving moles (ABCDEs).
- Dysplastic Nevi (Atypical Moles): Moles that look different from common moles (larger, irregular borders, varied color) and may have a higher risk of developing into melanoma. Often require monitoring or biopsy.
Hair & Scalp Disorders
- Traction Alopecia: Hair loss caused by prolonged or repetitive tension on the hair follicles, often due to tight hairstyles (braids, ponytails, extensions).
- Seborrheic Dermatitis of the Scalp (Dandruff): A common condition causing scaly patches, red skin, and stubborn dandruff on the scalp. Can also affect oily areas of the body.
- Androgenetic Alopecia (Male/Female Pattern Hair Loss): A common hereditary form of hair loss characterized by a receding hairline and thinning crown in men, and diffuse thinning over the top of the scalp in women.
Acne, Rosacea & Follicular Disorders
- Keratosis Pilaris: A common, harmless condition causing small, rough bumps on the skin, usually on the upper arms, thighs, cheeks, or buttocks, due to keratin buildup in hair follicles.
- Hidradenitis Suppurativa (Acne Inversa): A chronic, recurrent inflammatory skin condition featuring painful, deep-seated lumps, abscesses, sinus tracts, and scarring, typically in areas where skin rubs together (axillae, groin, under breasts).
- Acne Vulgaris (Comedonal, Papulopustular, Nodulocystic): A common skin condition characterized by pimples, blackheads, whiteheads, and sometimes deeper cysts and nodules, occurring when hair follicles become clogged with oil and dead skin cells. Severity can vary.
This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Claudia Rios.
- Medical-Grade Facials & Skincare Consultations: Professional facial treatments tailored to specific skin concerns and expert advice on developing an optimal at-home skincare regimen using medical-grade products.
- Scar Revision Surgery & Keloid Treatment (Surgical, Intralesional Injections): Procedures to improve the appearance of scars or treat problematic keloid scars, which may involve surgical excision, steroid injections, or other modalities.
- Microneedling (Collagen Induction Therapy) & Radiofrequency (RF) Microneedling: Procedures that create controlled micro-injuries in the skin to stimulate collagen and elastin production, improving skin texture, reducing scars (acne, surgical), fine lines, and stretch marks. RF Microneedling combines microneedling with radiofrequency energy for enhanced skin tightening and rejuvenation.
- Skin Cancer Screening & Mole Mapping (Dermoscopy & Digital Monitoring): Thorough examination of the skin for suspicious lesions, including moles and other growths. Utilizes dermoscopy for enhanced visualization and may involve digital mole mapping for high-risk patients to track changes over time.
- Dermal Fillers (Hyaluronic Acid, Calcium Hydroxylapatite, PLLA) for Volume Restoration & Contouring: Injectable gels (e.g., Juvederm®, Restylane®, Radiesse®, Sculptra®) used to restore facial volume, smooth out static wrinkles and folds, enhance lip volume, and contour facial features.
- Hyperhidrosis (Excessive Sweating) Treatment (Topical, Oral, Botulinum Toxin): Management options for excessive sweating of the underarms, palms, or soles, including prescription antiperspirants, oral medications, and botulinum toxin injections.
- Cyst Excision and Drainage of Abscesses: Surgical removal of various types of skin cysts (e.g., epidermoid, pilar) and incision and drainage for skin abscesses.

- Are consultations and dermatological treatments with Dr. Rios, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary consultations with a licensed Dermatologist like Dr. Rios, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. Rios's office or Ontario Health Insurance Plan (OHIP) beforehand, especially if there's a potential cosmetic component.
- Do I need a referral to see Dr. Rios, a Dermatologist?
- Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. Rios. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.
- What kind of sunscreen does Dr. Rios recommend?
- While specific brand recommendations can vary, Dr. Rios would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. Rios can provide personalized recommendations based on your skin type and lifestyle during your consultation.
- If Dr. Rios recommends phototherapy, what does that involve?
- Phototherapy, also known as light therapy, is a medical treatment where your skin is exposed to specific wavelengths of ultraviolet (UV) light under strict medical supervision. Dr. Rios might recommend it for conditions like psoriasis, eczema, vitiligo, or cutaneous T-cell lymphoma. Treatments are typically given 2-3 times a week in a specialized light cabinet or with a handheld device for smaller areas. The type of UV light (e.g., Narrowband UVB, PUVA) and treatment duration are carefully controlled. It works by reducing inflammation and slowing down the rapid growth of skin cells. You'll be given specific instructions, including eye protection.
