The Seacoast September Skin Reset: Reversing Summer Sun Damage & Prepping for Fall

As the humid beach days of August give way to the crisp, breezy mornings of September here on the Seacoast, you are probably swapping your swimsuits for sweaters. But while you’re updating your wardrobe, are you updating your skincare routine?

The transition from summer to fall is one of the most critical times for your skin. Months of sun exposure, salt water, and outdoor adventures often leave behind a few unwanted souvenirs: dark spots, uneven texture, and a compromised moisture barrier. Furthermore, as New Hampshire’s air becomes cooler and drier, skin that felt perfectly hydrated in July can suddenly feel tight and irritated.

Here is our Seacoast Dermatology guide to hitting the “reset” button on your skin this September.

1. Undo the Summer Sun Damage

Even if you were diligent with your SPF at Hampton Beach, prolonged sun exposure can trigger melanin production, leading to sun spots, freckling, and hyperpigmentation.

• At home: Incorporate brightening ingredients like Vitamin C and Niacinamide into your morning routine to help even out your complexion.
• At the clinic: Fall is universally recognized by dermatologists as “peel and laser season.” Because you are spending less time in direct, intense sunlight, September is the perfect time to book chemical peels or laser treatments to safely lift away summer sun damage and reveal fresh, healthy skin.

2. Swap Your Lightweight Lotion for a Richer Cream

During the humid summer months, a lightweight, oil-free gel or lotion is usually enough to keep your skin happy. However, brisk autumn winds and the impending reality of indoor heating will quickly strip moisture from your skin. Now is the time to transition to a heavier cream containing ceramides and hyaluronic acid. These ingredients help lock in moisture and reinforce your skin’s natural barrier against the harsher seacoast weather.

3. Reintroduce Retinoids

Many people dial back their use of retinoids (Vitamin A derivatives) during the summer because they can make the skin highly sensitive to the sun. As the UV index drops in September, it’s a great time to slowly reintroduce retinol or prescription retinoids back into your nightly routine. This will help stimulate collagen production and speed up cellular turnover, smoothing out the rough texture left behind by the summer elements. (Tip: Start slow! Use it just two or three nights a week to avoid irritation).

4. Don’t Ditch Your SPF!

This is the most common mistake we see in the fall. Just because the temperature is dropping doesn’t mean the sun’s UV rays are taking a vacation. UVA rays—the ones responsible for premature aging and skin cancer—are present all year long and can easily penetrate through New England’s famous overcast autumn clouds. Continue applying a broad-spectrum sunscreen of at least SPF 30 every single morning.

5. Schedule Your Annual Skin Check

Summer sun exposure can cause new moles to appear or existing ones to change. September is an excellent reminder to schedule a comprehensive skin cancer screening. Early detection is the best prevention, and getting into the habit of a post-summer skin check will give you peace of mind heading into the holidays.
