Why SPF Is Non-Negotiable
UV radiation is responsible for up to 80% of visible skin aging — fine lines, dark spots, uneven texture, and loss of elasticity. It does not matter how many serums or treatments you layer on top. Without daily sun protection, you are actively undoing the work of every other product in your routine.
Sunscreen is not the last step in your skincare routine. It is the step that makes every other step worth doing.
UVA vs UVB: Know the Difference
UVB rays cause sunburn — they are the ones that turn your skin red on a beach day. UVA rays penetrate deeper into the dermis, causing long-term structural damage and premature aging. UVA rays are present year-round, pass through clouds, and even penetrate glass windows. This is why SPF on an overcast day or indoors near a window still matters.

Choosing the Right Formula
Mineral sunscreens containing zinc oxide or titanium dioxide sit on top of the skin and physically deflect UV rays. Chemical sunscreens absorb UV radiation and convert it to heat. Neither is universally better — it comes down to your skin type, tone, and personal preference. Those with sensitive or acne-prone skin often do better with mineral formulas, while chemical options tend to feel lighter under makeup.

How Much Is Enough
The standard recommendation is a quarter teaspoon for the face alone — roughly the size of a small coin. Most people apply less than half that amount, which means the SPF protection they are getting is significantly lower than what is printed on the label. Reapplication every two hours of sun exposure is equally important and equally ignored.
The best sunscreen is the one you will actually use every single day — find a texture you love and make it a habit.

Daily SPF use is the single highest-return investment in long-term skin health. Start today — your skin in ten years will thank you for it.
