Glow Definition
In skincare, UVA refers to a type of ultraviolet radiation from the sun that reaches the deeper layers of the skin. Often associated with long-term skin changes, UVA rays are consistently present throughout daylight hours — even on cloudy days or through windows.
Unlike UVB, which is stronger during peak sun hours, UVA tends to be more consistent year-round and is a key reason many broad-spectrum SPFs emphasize daily protection. Understanding UVA is essential when evaluating how well a product defends against environmental exposure and helps preserve skin’s visible glow over time.

Why It Matters
UVA rays don’t cause immediate visible effects like sunburn, but their deep penetration can gradually influence the way skin looks and feels. Because they pass through glass and remain steady throughout the day, consistent exposure adds up — often without you realizing it. For routines focused on preserving skin’s glow long-term, UVA awareness is a quiet essential.
Many formulas labeled as “broad-spectrum” are specifically designed to address UVA protection alongside UVB. This distinction matters if you’re layering makeup or skincare indoors, traveling, or relying on ambient light. The better your understanding of UVA, the more intentional your daily barrier strategies can become.
GLOW TIP Even when you’re indoors, apply a broad-spectrum SPF — UVA rays can still pass through windows and subtly influence your skin’s visible radiance over time.
Why We Love It For Glow
While we don’t love UVA itself, understanding it is essential if you’re serious about preserving your glow. UVA rays are sneaky — they don’t burn, but they do beam through clouds, windows, and glass year-round. That makes them one of the most consistent (and underestimated) forces working against lasting luminosity, even if you never step outside.
In glow routines, prevention is power. UVA exposure can contribute to dullness and uneven tone over time — two of the most common roadblocks to skin that looks effortlessly radiant. That’s why daily SPF with broad-spectrum protection isn’t just a recommendation here — it’s a non-negotiable glow standard.

FAQ
What does UVA protection mean in skincare?
UVA protection refers to a product’s ability to shield skin from long-wave ultraviolet A rays, which can penetrate deeper into the skin than UVB. These rays are present year-round and can pass through glass, making daily protection especially relevant — even when it’s cloudy or you’re indoors near windows.
How do I know if my sunscreen protects against UVA?
To check for UVA coverage, look for the words “broad spectrum” on the sunscreen label. In some regions, you might also see a PA rating or a circle around the UVA symbol, both of which indicate dedicated protection against these deeper-penetrating rays.
Is UVA exposure only a concern during summer?
Not at all — UVA rays are consistent throughout the year and don’t vary by season or weather. That means they can affect your skin during everyday moments like commuting, working near windows, or sitting by the pool — not just during summer vacations or sunny beach days.
