The Truth About SPF: Your Skin’s Daily Dose of Protection Boston Medical Aesthetics

At Boston Medical Aesthetics, one of the most important skincare habits we stress with every patient is daily SPF use- rain or shine, summer or winter. Why? Because the sun is the #1 cause of premature skin aging, and protecting your skin from it is one of the easiest, most powerful ways to maintain a healthy, youthful glow.

Let’s break down why SPF matters so much and what can happen when you skip it.

Sun Damage is More Harmful Than You Think

The sun emits ultraviolet (UV) rays, which penetrate the skin and cause damage at the cellular level—even on cloudy days or through windows. This damage adds up over time, leading to:

• Fine lines and wrinkles
• Hyperpigmentation and sunspots
• Loss of collagen and skin elasticity
• Rough texture and uneven tone
• Broken capillaries and redness
• Skin cancers, including melanoma

In fact, up to 90% of visible signs of aging are caused by sun exposure- not genetics!

Why Daily SPF is Non-Negotiable

Even if you're not lounging at the beach, UV exposure happens every day. Walking to your car, sitting by a window, or running errands can all lead to cumulative sun damage.

That’s why we recommend applying a broad-spectrum SPF 30 or higher every single morning, as the final step in your skincare routine. This helps:

• Prevent premature aging
• Minimize pigmentation and discoloration
• Preserve the results of your injectables and skin treatments
• Reduce the risk of skin cancer

Medical-Grade SPF: Better Protection, Better Skin

Not all sunscreens are created equally. At Boston Medical Aesthetics, we carry medical-grade formulas from trusted brands like SkinCeuticals, SkinBetter, and ISDIN that go beyond basic protection. Many include added antioxidants, hydrators, and tinted options for a flawless finish. Explore options in our medical-grade skincare collection to find the right daily shield.

Our Expert Tip

Apply a nickel-sized amount to your face and don’t forget your neck, chest, and hands. Reapply every 2 hours if you're outdoors. And yes- you still need SPF even if your makeup has it!
