Understanding Sunscreen: Chemical vs. Physical and Post-Laser Care

What to know when choosing the best sunscreen for your skin.

During the summer, and year-round, the importance of wearing sunscreen cannot be overstated. At our practice, we often get questions about the types of sunscreens available and the best options for post-treatment care. There are different variations of SPF including chemical and physical, and ultimately it comes down to choosing the correct one.

Chemical vs. Physical: What’s the Difference?

Chemical Sunscreens

Chemical sunscreens contain organic compounds, such as avobenzone, octisalate, and octocrylene, that absorb UV radiation and convert it into heat, which is then released from the skin. These sunscreens typically have a greasier feel, have a more transparent color on the skin, and are sold in drugstores, making them a popular choice for most people.

Physical Sunscreens

Physical sunscreens, also known as mineral sunscreens, contain active mineral ingredients like zinc oxide and titanium dioxide. They work by sitting on top of the skin to deflect and scatter UV rays. Physical sunscreens are often thicker and can potentially leave a slight white cast, but they are generally more stable and less likely to irritate sensitive skin.

Why Physical Sunscreens Are Better

  1. Immediate Protection: Unlike chemical sunscreens that require time to absorb and become effective, physical sunscreens provide immediate protection upon application and create a physical barrier between the skin and sun instead of relying on potentially irritating chemicals.
  2. Broad Spectrum: Physical sunscreens offer broad-spectrum protection against both UVA and UVB rays, helping to prevent skin damage, premature aging, and skin cancer.
  3. Less irritation: For individuals with sensitive skin or conditions like rosacea, physical sunscreens are often recommended because they are less likely to cause irritation, allergic reactions or clog pores.
  4. Stability: Mineral sunscreens are more photostable, meaning they don’t degrade as quickly in sunlight compared to many chemical filters. This stability ensures longer-lasting protection throughout the day.

Our sunscreen options function more like skincare with SPF to hydrate the skin and protect against free radical damage with vitamin C. Options range from clear for everyday wear to tinted which layers nicely underneath makeup; these include our Sheer Physical SPF and Mineral Lightly Tinted SPF.

Importance of Sunscreen After Laser Treatments

Lasers can be transformative for the skin improving texture, tone and overall appearance. However, they also leave the skin temporarily more vulnerable, which is why we include SPF in all post-care packages. Here’s why it’s essential:

  1. Protects Healing Skin: After laser treatments, the skin may be red, sensitive, or compromised. Sunscreen shields this delicate skin from harmful UV rays, preventing further damage.
  2. Reduces Hyperpigmentation: Newly treated skin is more susceptible to hyperpigmentation. Wearing sunscreen helps to mitigate the risk of dark spots and uneven skin tone, ensuring you achieve the best possible results from your treatment.
  3. Promotes Recovery: Using a physical sunscreen can aid in the healing process, reducing inflammation and irritation associated with sun exposure.
  4. Enhanced Treatment Results: Consistent sun protection helps maintain and enhance the results of laser treatments, allowing you to enjoy your refreshed appearance for longer.

Our Recommendations

As you navigate your sun protection options, consider opting for a physical sunscreen such as the Mineral Matte SPF, especially if you have sensitive skin or have recently undergone laser treatments. Protecting your skin is a crucial step in maintaining its health and beauty, and wearing sunscreen daily can make a significant difference in the long run.
