Questions, Answers, and Information Directly from Dr. Ingrid Trenkle

Sourced directly from Dr. Ingrid Trenkle's social posts and replies.

What should I know about SPF and sunscreen?
SPF (Sun Protection Factor) measures how well a sunscreen protects your skin from UVB rays, which are primarily responsible for sunburn. Higher SPF numbers provide greater protection, but no sunscreen blocks 100% of UV rays, making daily use and reapplication important. Dr. Trenkle's favorite sunscreens are ISDIN Actinica and ISDIN Eryfotona Ageless, both offering excellent daily sun protection and available for purchase in her office.

What are Actinic Keratoses (AKs) and why are they important?
Actinic keratoses (AKs) are rough, scaly spots caused by years of sun exposure. While not skin cancer themselves, they are considered precancerous and have the potential to develop into squamous cell carcinoma if left untreated. Regular skin checks and early treatment are crucial to prevent their progression and maintain healthy skin.
Source →
What can I expect during a cosmetic consultation?
A cosmetic consultation is an opportunity to discuss your goals and concerns, whether you're interested in reducing wrinkles, improving skin texture, addressing sun damage, or learning about treatment options. The practice provides expert guidance without pressure and creates personalized treatment plans tailored to your individual needs.
Source →
What are common warning signs of skin cancer?
Not all skin cancers initially appear alarming. Overlooked warning signs include a spot that won’t heal, a pimple-like bump that keeps returning, a scaly or rough patch that doesn’t go away, a mole that changes in size, shape, or color, a sore that bleeds easily, or a new spot that looks different from others. If you notice any of these changes, it’s crucial to have them evaluated by a dermatology provider, as early detection is key.
Source →
What are Dr. Trenkle's recommendations for sun protection?
It's important to protect your skin while enjoying the sunshine. Dr. Trenkle recommends applying a broad-spectrum SPF, seeking shade when possible, and reapplying sunscreen throughout the day, especially if you're swimming or spending extended time outdoors.
Source →
Why are annual skin exams important?
Annual skin exams are effective for early detection of skin cancer and precancerous lesions, often preventing them from becoming serious problems. Even if you don’t notice any concerning spots, a trained dermatology provider can identify changes difficult to see on your own. Early detection makes a significant difference in treatment outcomes, so Dr. Trenkle recommends scheduling your yearly skin check and making your skin health a priority.
Source →
What is the difference between dry skin and eczema?
Dry skin and eczema are not always the same condition. Dry skin is often caused by environmental factors like weather, hot showers, or harsh skincare products. Eczema, on the other hand, is a chronic inflammatory skin condition that can cause redness, itching, irritation, and recurring flare-ups. While both can appear similar, proper diagnosis is important to determine the best treatment plan.
Source →
What is cryotherapy and what is it used for?
Cryotherapy uses liquid nitrogen to freeze and destroy unwanted skin lesions, including warts, actinic keratoses (precancerous spots), and certain benign growths. This treatment is quick, effective, and can often be performed in just a few seconds right in the office.
Source →
How often should sunscreen be reapplied?
Sunscreen should be reapplied every 2 hours when spending time outdoors, and especially if you're swimming or spending extended time outdoors.
Source →
What is a dermatoscope and how is it used?
A dermatoscope is a specialized handheld tool that allows dermatology providers to closely examine the skin using magnification and light. It helps evaluate moles, lesions, and other skin concerns in greater detail than the naked eye, and is especially helpful in identifying suspicious features that may indicate skin cancer or other skin conditions, making it an important tool for early detection and accurate diagnosis.
Source →
What is an excision procedure?
An excision is a procedure where an entire lesion or suspicious area of skin is carefully removed for further evaluation. This technique is often used to remove and fully examine a mole, cyst, or possible skin cancer, serving both diagnostic and treatment purposes. The procedure is performed under local anesthesia, and stitches are typically placed afterward to promote healing.
Source →
What is a punch biopsy?
A punch biopsy is a procedure used to obtain a deeper sample of skin for accurate diagnosis. It involves using a small circular instrument to remove a tiny section of skin to evaluate conditions involving deeper layers. Punch biopsies are commonly used to help diagnose rashes, inflammatory skin conditions, suspicious lesions, and certain types of skin cancer. The area is numbed beforehand, and stitches may occasionally be placed depending on the size of the biopsy.

Industry Payments

Federal law (the Physician Payments Sunshine Act) requires drug and medical-device companies to report anything of value they give to a physician — consulting and speaking fees, research funding, travel, royalties, and even meals. Medicare publishes all of it in a public database called Open Payments. We show it here so you don't have to go looking for it.

Total received (2024)

$4,777

Payments

144

Compared to peers

Moderate

Dr. Ingrid Trenkle received $4,777 across 144 payments in 2024. That is higher than about 71% of the physicians here who received any industry payment. Most of it was categorised as food and beverage, and the largest single payer was REVANCE THERAPEUTICS, INC..

What this means for your care

  • A disclosed payment is a business relationship, not evidence of wrongdoing, and it says nothing on its own about the quality of your care.
  • Most payments are small. Across the physicians listed on NavMDs, the single most common category is food and beverage at industry-sponsored talks.
  • Larger consulting, speaking or royalty payments mean an ongoing financial relationship with a company whose products your doctor may use or recommend. That is worth knowing about, and it is reasonable to ask about.
  • A fair question to ask: “Do you have a financial relationship with the maker of the implant, filler or device you're recommending — and what alternatives did you consider?”
