At Precision Aesthetics, we’ve been guiding clients through the skincare maze for nearly two decades. And when it comes to sunscreens, our message has been consistent from the beginning.
You don’t need sunscreen every second you’re outside.
In fact, 15 to 20 minutes of full-body sun exposure without any sunscreen is not only safe — it’s beneficial. That natural sunlight helps your body produce vitamin D, supports your immune system, and gives you that unmistakable lift in mood — the same feeling people chase during winter vacations.
But more isn’t always better.
Excess sun exposure accelerates skin aging — plain and simple.
UV rays break down collagen and elastin, leading to fine lines, loose skin, sun spots, and uneven tone. Over time, it undoes the very results you’ve worked so hard to achieve — and ironically, brings you right back to us to fix the damage.
So here’s how to get the benefits of the sun without paying the price:
After your 15–20 minutes of daily exposure, your best protection is a physical (mineral) sunscreen made with zinc oxide or titanium dioxide. These sit on the surface of your skin and reflect UV rays — unlike chemical sunscreens that absorb into your bloodstream.
And don’t overlook the basics: clothing, hats, umbrellas, and shade are simple, effective physical barriers. No ingredients. No risk.
For most people, that’s all you need to know.
But if you’re the type who wants to understand the “why,” here’s more:
To improve cosmetic appeal, many newer sunscreens use micronized or nano particles of zinc and titanium to eliminate the white cast. They look nicer on the skin — but they also raise important questions.
In lotions and creams, these nano particles don’t appear to penetrate healthy skin.
In sprays and powders, however, inhalation is a concern — and nano titanium dioxide is classified as possibly carcinogenic when inhaled.
Some forms can even generate free radicals under UV light unless properly coated — and most consumers have no idea what they’re applying.
Chemical sunscreens have already been banned in places like Hawaii and Palau due to reef damage. Even nano minerals are under scrutiny for potential marine toxicity.
So here’s our guidance:
– Get 15–20 minutes of direct sunlight each day — without sunscreen
– After that, use a non-nano mineral sunscreen
– Avoid sprays and powders, especially around children
– Reapply during extended sun exposure
– Protect with shade, clothing, wide-brim hats, and sunglasses
And be thoughtful with children. Their endocrine systems are still developing — and they’ll live with these choices far longer than we will.
If you wouldn’t eat it, don’t put it on your skin.
And if you’ve already invested in your skin’s appearance with us — treatments to lift, firm, brighten, and even out your tone — think of sunscreen as your maintenance plan.
Sun damage is one of the top reasons patients come back sooner than expected.
Preserve your results. Stay ahead of the damage.
We’re not here to scare you or sell you anything you don’t need.
We’re here to keep you informed — and protected — every step of the way.
We educate. You decide.

Because sunscreen shouldn’t be confusing.
But it should be safe.
