Inside a Dermatologist’s Beauty Cabinet: Marnie B. Nussbaum

Sebamed Liquid Face & Body Wash

“I love this cleanser because it gently deep-cleans without drying my face out or causing any irritation. It doesn’t break down the skin barrier, which is essential for healthy, clean pores. In general, there is rarely a need to splurge on basic cleansers and moisturizers, which only touch your face for a few seconds. Most basic cleansers remove oil and dirt. Traditional bar soaps can raise skin’s pH from its ideal 5.5 up to 9 or 10, creating that dry, tight feeling.” $20, sebamedusa.com

SkinCeuticals C E Ferulic

“This serum has a specific form of vitamin C in it that has been scientifically proven to be more effective than any other form out there. It is a fabulous antioxidant anti-aging serum. It protects your skin against the environment’s dirtiest bacteria. It also reduces fine lines and wrinkles while slowing down the appearance of aging.” $162, skinceuticals.com

La Mer Eye Concentrate

“It helps to soften the appearance of dark circles, surface discoloration and unevenness. People tend to spend more on eye cream for a number of reasons. Because you only need to use very little at a time, eye cream usually lasts longer than regular products. Remember, less is more.” $195, cremedelamer.com

EltaMD UV Daily Broad-Spectrum SPF 40

“Sunscreen is extremely important. My favorite kind to use is Elta Sunscreen. It is fragrance-free and mineral-based, so it does not clog pores or create unnecessary oil. I really like this specific kind because it blocks harmful sunrays without affecting the top layers of skin. Try to avoid nano-particle formulas; they can penetrate your skin layers, possibly causing harm.” $26, eltamd.com
