One of the most common questions asked at Pure by Alpha Dermatology is, “What is the best sunscreen to use?” It is one of our favorite skincare questions because sunscreen is one of the most important parts of protecting and maintaining healthy skin.
Sunscreen is not just for vacations, pool days or beach trips. Daily SPF helps protect your skin from premature aging, fine lines, wrinkles, sun spots, discoloration, melasma flare-ups, hyperpigmentation and even skin cancer risks. If you are investing in facials, lasers, peels or brightening treatments, sunscreen helps protect those results and keeps your skin looking its best.
When choosing SPF, most people do not realize there are two main types: mineral sunscreen and chemical sunscreen. While both protect your skin from harmful UV rays, they work very differently and at Pure by Alpha Dermatology, we always recommend mineral sunscreen first.
Mineral sunscreen, also called physical sunscreen, uses ingredients like Zinc Oxide and Titanium Dioxide. These ingredients sit on top of the skin and create a barrier that reflects and deflects UV rays away from the skin. One of the biggest benefits is that mineral sunscreen starts working immediately after application, so there is no waiting time before heading outside.
We love mineral sunscreen because it is gentle, effective and ideal for sensitive or acne-prone skin. It is often the better choice for patients dealing with rosacea, melasma, pigmentation concerns or post-treatment healing after procedures like lasers and chemical peels. It protects the skin without creating unnecessary irritation, which is especially important when your skin barrier is trying to heal and stay balanced.
Chemical sunscreen works differently. It uses ingredients like Avobenzone, Octinoxate, Oxybenzone and Octocrylene. Instead of sitting on top of the skin, these ingredients absorb UV rays, convert them into heat and then release that heat through the skin.

Many people are surprised to learn that chemical sunscreen can sometimes cause more irritation. Common complaints include stinging, burning, breakouts, watery eyes and sensitivity, especially for patients with reactive skin. It also requires about 15 to 20 minutes before sun exposure to become fully effective.
One concern people often have about mineral sunscreen is the white cast. The good news is that formulas have come a long way. Many medical-grade mineral SPFs today are lightweight, tinted and blend beautifully into the skin without looking heavy or chalky.
So, what is the best sunscreen to use? Our answer is simple: the best sunscreen is one that protects your skin without causing irritation and for most patients, that means mineral sunscreen.
Our SPF rules are simple: choose SPF 30 or higher, make sure it is broad-spectrum, reapply every two hours and never forget your neck, chest, hands and ears. Most importantly, wear it every single day, even when it is cloudy.
Because sunscreen is not seasonal. It is skincare.
And when in doubt, choose mineral.
