Finding a skincare routine that works for you is no easy feat. Actress Zosia Mamet knows this on a personal and professional level, as her career motivated her pursuit of a better-looking complexion. \u201cSkin is so important to me because it\u2019s such a huge part of my job,\u201d Mamet says, explaining that it can be unavoidably tied to her confidence. Finding her go-to products was an ongoing process that she worked on with dermatologist Melissa K. Levin, M.D., who practices in New York City. It required some trial, a lot of error, and even more sunscreen. \u201cSomething Dr. Levin and I talk a lot about is taking care of what I have now with a realistic long-term goal,\u201d she says. \u201cIf you take care of your inside and outside in a really simple but conscious and proactive way, your body and your skin are going to thank you. It\u2019s about being consistent and finding something that works for you.\u201d Here, Mamet and Dr. Levin\u2014who are both spokespeople for Isdin products\u2014outline the key elements to remember when creating your own skincare routine. Focus Your Daytime Routine Around Protection Whether you spend a ton of time outdoors like Mamet, or simply get sunshine from your nearest window, it\u2019s important to wear sun protection. Between her busy filming schedule and the time she spends outdoors riding horses (one of her longtime passions), Mamet\u2019s skin is constantly exposed to the sun, so incorporating Isdin\u2019s Eryfotona Actinica sunscreen was a key element in her routine from the start. \u201cDr. Levin and I started with the Eryfotona sunscreen because I needed something that I\u2019d be able to wear under makeup when I shoot outdoor scenes,\u201d she says. She goes on to explain that the formula doesn\u2019t budge, or impact her makeup look on set\u2014even after 18 hour shoot days. Mamet also uses Isdin Isdinceutics Flavo-C Ultraglican \u2014a vitamin C skin treatment\u2014to protect her skin from free radical damage (which can ultimately cause dark spots and fine lines) during the day. \u201cVitamin C is an effective antioxidant that helps to brighten discoloration, while also neutralizing free radical damage,\u201d says Dr. Levin. Note, that vitamin C can become less effective when exposed to UV light. (This makes using your SPF more crucial.) Be Careful to Not Use Too Many Products Before Mamet had established her skincare routine, throwing everything but the kitchen sink at a breakout was her common strategy. She explains that after Dr. Levin helped her put together a lineup that agreed with her, her acne treatments appeared to work more effectively. According to Dr. Levin, too many formulas at once can disrupt your skin\u2019s barrier, which often leads to larger problems. \u201cI always say less is more,\u201d Dr. Levin says. \u201cKeep your skincare curated to the basics so that if you do have a big breakout, treating it won\u2019t require all the heroics.\u201d The logic is simple: you\u2019ll know how each of your go-to products impacts your skin\u2014and can figure out how to treat your problem area more easily. Seek Out Ingredients with Impact Mamet prefers to streamline her approach by focusing on potent ingredients. Case in point: Her nighttime skincare routine, which consists of three products: a cleanser, the Isdin K-Ox eye cream , and Isdin Isdinceutics Melatonik serum. Melatonik is the star of her nighttime routine. Formulated with a generous amount of vitamin C, bakuchiol, and melatonin, it\u2019s packed with everything Mamet needs to help offset the sun exposure from her day. The melatonin in the formula acts like an antioxidant, and according to Dr. Levin, applying it topically can help with your skin\u2019s restorative processes. Bakuchiol is a naturally-based retinol alternative that can help support collagen production, fading hyperpigmentation, and turning over skin cells. \u201cIt\u2019s a great, gentle alternative, especially if you\u2019re in the sun a lot as it won\u2019t make your skin flaky or sensitive.\u201d Mamet applies Melatonik all over her face, then works any excess onto her neck and the back of her hands, which are regularly exposed when she\u2019s horseback riding. Give Your Products Time to Work A big part of building a skincare routine is understanding that patience is fundamental. \u201cYour skin naturally takes six weeks to go through one cycle, so as much as you\u2019d like to see results in a week or two, you need to give your formulas time to work on your skin,\u201d Dr. Levin explains. \u201cTypically, I won\u2019t see my patients for six to eight weeks after determining their routine, because I want it to be the same for that amount of time before deciding to change something, add in a new product, or keep it the same.\u201d \u201cMy skin is super sensitive,\u201d Mamet says, \u201cso if you put something on it that it doesn\u2019t like, it will just give you the finger. We were having trouble finding things that didn\u2019t make me too oily or too dry, and things that didn\u2019t make me break out, but once we found a plan and my skin adjusted to the routine, we stuck to it.\u201d Take Care of *All* Aspects of Your Wellbeing Remember: Self care is skin care, as stress can manifest in physical ways. Mamet certainly isn\u2019t immune to the occasional stress pimple, and after a few attempts trying to battle the breakout with products, she has found that a more holistic approach works best. Her philosophy is simple\u2014be proactive and give your body what it needs now so it will take care of you later. Dr. Levin echoes the sentiment, and explains that your skin will respond to other aspects of your wellbeing. \u201cPeople sometimes think that skin care can do absolutely everything, but a big part with Zosia was managing her stress levels and getting enough exercise, because those things do impact your skin in general,\u201d she adds.
