The world’s most trusted dermatologist just simplified everything you thought you knew about skincare including the truth about SPF!
If you’re finding that the “science-backed” claims on every cosmetic product somehow contradicts the science-backed claims on the bottle next to it. Then this article is for you. One dermatologist finally cuts through the noise with a skincare routine that is so simple anyone can do it.
In a recent episode of The Mel Robbins Podcast that prompted more listener questions than almost any other episode in the show’s history, Dr. Shereene Idriss, one of the most respected dermatologists in the world and the founder of Idriss Dermatology in New York delivered something the beauty industry generally disincentivises: clarity. Her message, stripped back, is this. The routine you need is not the one being sold to you. And the most important work you will ever do for your skin does not happen in the bathroom.
Step 1 – Inside out, not outside in
Before Dr. Idriss said a word about products, she said this: 80% of how we age has to do with habits. Cumulative sun exposure, lifestyle, diet, alcohol, these things, accumulated over time, are doing more work on your skin than anything you put on it. Sleep and diet are not supporting acts in the skincare story. They are the main event. Sugar and refined carbohydrates, in particular, are implicated in hormonal acne, especially the jawline breakouts that are so characteristic of adult acne in women in their thirties, and no retinol on earth will fully outwork a diet that is chronically inflammatory. This is not a comfortable message for an industry built on product sales. It is, however, the message from the dermatologist’s chair.
The three things you actually need
Dr. Idriss identifies three categories for every routine: protecting your skin, supporting your skin barrier, and driving long-term change. In product terms, that translates to a gentle cleanser, a moisturiser, and a daily SPF. That is the whole routine. Everything else, the activities, the treatments, the brightening serums, comes after you have mastered these three, and only then.
Cleanser: At night only, unless your skin is very oily. In the morning, water is enough. Dr. Idriss recommends Vanicream Gentle Facial Cleanser as a simple, non-stripping option available online, nothing fancy, nothing with an agenda, just something that removes the day without compromising the barrier. For drier skin, a more hydrating formula works equally well. The function is foundation-setting, not transformation. The key here is to use face cloths to really dig into the pores, haven one for every day of the week!
Moisturiser: The word collagen on a moisturiser label is doing marketing work, not scientific work. A hydrating moisturiser hydrates, it does not replenish collagen, regardless of what the packaging implies. Understanding what you are actually buying is, Dr. Idriss argues, half the battle. A simple, fragrance-free moisturiser is all that is required here. Weleda Skin Food, which she has recommended elsewhere, is a rich, multipurpose option that costs less than a coffee at an airport and celebrities love it!
SPF: Non-negotiable, year-round, full stop. Sunscreen can also double as your moisturiser, particularly for oily or combination skin, which simplifies the routine further. The damage that sunscreen prevents, hyperpigmentation, brown spots, accelerated collagen breakdown, is the damage that no serum can fully reverse.
After the basics: the ingredients worth adding
Once your barrier is supported and your skin is stable, Dr. Idriss endorses a focused set of actives. A retinoid at night is the gold standard for both acne and ageing, it addresses both simultaneously and has decades of clinical evidence behind it. Begin slowly, two nights a week, and build. For post-acne pigmentation, Vitamin C in the morning (the Timeless 20% Vitamin C + E + Ferulic Acid serum is consistently recommended as the drugstore answer to expensive equivalents) addresses discoloration without drama. Niacinamide and azelaic acid are both excellent for calming inflammation and reducing the red and brown marks that linger after breakouts. Exfoliating acids, glycolic or lactic, once to three times a week at night, not every day, not layered with everything else.
The adult acne conversation we’re not having clearly enough
Adult acne is not teenage acne in an older body. It is hormonal, it behaves differently, and it requires a different response. Harsh, drying treatments strip the barrier, increase oil production, and make things worse. The answer is gentleness, not aggression. And for the women whose breakouts follow a reliable hormonal pattern, appearing reliably along the jawline in the week before a period, the conversation about internal factors, stress management, sugar reduction, and in some cases a GP referral, is the one that actually needs to happen.
The product edit, at a glance
Vanicream Gentle Facial Cleanser, cleanser, night (and morning if very oily). Simple Kind to Skin Moisturising Facial Wash, gentler alternative for dry or sensitive skin. Any SPF 30–50+ with a formula you will actually wear daily, the one you use is infinitely better than the one you don’t. Timeless 20% Vitamin C + E + Ferulic Acid Serum, morning antioxidant. A retinol or retinoid of your choice, begin at the lowest percentage, build slowly. Azelaic acid, for inflammation and marks. Weleda Skin Food, rich overnight moisturiser.
The bathroom counter does not need to be complicated. Your skin needs consistency, a functioning barrier, daily sun protection, and, more than any of this, a body that is being fed, rested, and not run entirely on cortisol.
