Which retinoids can be used during the day, and what products does Dr. Wolinsky recommend?
Adapalene is the only retinoid that is not deactivated by the sun, making it suitable for daytime use. Dr. Wolinsky notes that La Roche-Posay offers Adapalene 0.1%, and other over-the-counter brands exist and vary.
What are Dr. Wolinsky's recommendations for sunburn treatment?
While aloe vera can feel cooling, it doesn't do much to hydrate a sunburn. Aquaphor is a good pick for healing a sunburn; it's an ointment that is hydrating and greasy, which helps speed up healing. Dr. Wolinsky's number one pick for healing a sunburn is Biophy, which requires a prescription and recruits cells to heal quicker.
How can I treat an infected cuticle, and when should I see a doctor?
You can try washing your hands, soaking your fingers in warm water, and attempting to express the pus. If this self-treatment is unsuccessful, you should consult a dermatologist.
Can Vitamin C and Retinol be used together, and what product does Dr. Wolinsky recommend?
Typically, doctors recommend using Vitamin C and Retinol at two different times due to their varying pH requirements. However, Matter-of-Fact Wrinkle and Texture Concentrate uses Actisolv™ L-ascorbic Acid technology, allowing it to be used effectively with encapsulated retinol. This product also contains Focutuel, Ferulic Acid, and Azelaic Acid, which contribute to its impressive clinical data. Patients have noted improvements in dark spots, fine lines, and wrinkles after just four weeks of use, with continued improvement up to 16 weeks. Dr. Wolinsky recommends starting this serum two to three times a week, increasing frequency as tolerated.
What is Dr. Wolinsky's recommended body care routine and moisturizer for dry skin?
For best results in body care, Dr. Wolinsky recommends taking a warm shower, patting dry with a towel, using a body brush to boost circulation, and then applying Vaseline Intensive Care Advanced Repair Lotion. This derm-approved moisturizer is formulated with ultra-hydrating lipids and micro droplets of Vaseline jelly to fortify the skin barrier, replenish moisture, and keep skin healthy and hydrated. It is also non-greasy and rich.
What cleanser does Dr. Wolinsky recommend and why?
Dr. Wolinsky repeatedly recommends Cetaphil Gentle Skin Cleanser, calling it the 'literal OG cleanser' that all dermatologists recommend. As a dermatologist, she looks for a soothing, versatile cleanser she can rely on. It hydrates the skin while cleansing, reinforces the skin barrier, and moisturizes even sensitive skin. Key ingredients include glycerin (a humectant) and niacinamide (a vitamin that improves tone and soothes). It gently removes dirt and impurities, provides long-lasting hydration, and can be used once or twice daily, with or without water.
