Your Back-to-School Skincare Guide for the Seacoast

As summer winds down and campuses across New Hampshire start buzzing again, older teens and college students are gearing up for a new semester. Between buying textbooks, moving into dorms, and navigating a new class schedule, your skin is probably the last thing on your mind. But as any Seacoast local knows, the seasonal transition into a New England fall—combined with the stress of a new school year—can throw your skin totally out of balance.

Whether you’re heading back to Portsmouth High, Exeter High, or the University of New Hampshire, the team at Seacoast Dermatology has put together the ultimate guide to keeping your skin clear, hydrated, and healthy this semester.

The New England Climate Factor: The Humidity Drop

Going to school in the Seacoast region is amazing, but it comes with unique environmental challenges for your skin. We transition from humid, sticky summers to crisp, dry, and windy autumns very quickly. When the humidity drops, the brisk autumn air can easily compromise your skin’s moisture barrier.

• Hydration is Non-Negotiable: As the air gets drier, lightweight summer gels might not cut it anymore. If your skin is overproducing oil, it might actually be crying out for moisture. Switch to a nourishing, non-comedogenic cream moisturizer to lock in hydration without clogging your pores.
• Sunscreen is a Daily Class Requirement: Don’t let the cooling temperatures fool you. You can easily get sun damage walking across the UNH campus or spending a crisp September afternoon near the coast. UV exposure continues throughout the fall, so apply a broad-spectrum SPF 30+ every single morning.

Stress, Sleep, and Midterm Breakouts

Let’s be real: high school and college are stressful. Late nights studying, a diet heavily reliant on dining hall food or late-night pizza, and the social pressures of a new year all trigger the release of cortisol.

Cortisol is a stress hormone that kicks your sebaceous (oil) glands into overdrive, which is exactly why that massive breakout always seems to appear the morning of a big presentation.

Pro-Tip: Resist the urge to aggressively scrub your skin or load up on harsh spot treatments when stress acne hits, as over-exfoliating can damage your barrier. Over-drying your skin will only cause more inflammation. Instead, use a gentle cleanser and a targeted salicylic acid or benzoyl peroxide treatment on active breakouts.

The 3-Step “Dorm-Room” Routine

When you’re sharing a communal bathroom or rushing to an 8:00 AM lecture, complex 10-step skincare routines just aren’t realistic. Keep it simple and consistent:

1. Cleanse (Morning & Night): Wash away sweat, oil, and pollution. If you have acne-prone skin, look for a cleanser with 2% salicylic acid to gently unclog pores. If your skin is sensitive from the brisk coastal wind, stick to a gentle, hydrating milky cleanser.
2. Moisturize: Apply a lightweight moisturizer while your skin is still slightly damp. This repairs your skin barrier and keeps the drier autumn air from stripping your face.
3. Protect (Morning Only): Finish with your SPF. Many modern sunscreens double as moisturizers, which can save you a step when you’re running late to class!
