Can You Tan with SPF? The Truth About Sunscreen and Tanning

For years, people have debated whether wearing sunscreen prevents tanning or if it’s possible to get that golden glow while staying protected. Many assume that applying SPF will completely block the tanning process, while others skip sunscreen altogether, believing it slows down their tan. But what’s the truth?
This article busts common myths about tanning and sunscreen and explains how you can safely tan while protecting your skin from premature ageing and sun damage, backed by scientific studies and expert recommendations.
Myth #1: Sunscreen Prevents Tanning Completely
The Truth: Sunscreen does not completely block tanning—it filters UV rays to reduce damage while still allowing melanin production.
Sunscreen works by absorbing or reflecting harmful UV rays, but it does not stop the tanning process entirely. Tanning occurs when your skin produces melanin, a pigment that darkens in response to UV exposure. Even when wearing sunscreen, some UV rays still penetrate the skin, triggering melanin production.
Scientific Evidence
A study published in the Journal of Investigative Dermatology (2018) found that people who wore SPF 30 sunscreen still developed a tan over time, albeit at a slower and safer rate compared to those who tanned without SPF. This indicates that sunscreen does not prevent tanning but helps reduce the risk of sunburn and DNA damage (Olsen et al., 2018).
Why You Still Tan with SPF
Sunscreen protects against burns, not the tanning process itself.
No sunscreen blocks 100 per cent of UV rays. For example, SPF 30 filters about 97 per cent of UVB rays, while SPF 50 filters about 98 per cent.
A gradual, sunscreen-protected tan lasts longer and looks healthier because it reduces excessive sun damage and peeling.
Many dermatologists recommend tanning with SPF because it allows for a safer, more even tan without the risk of sunburn, which can cause premature ageing, pigmentation, and even skin cancer.
Myth #2: The Higher the SPF, the Less You Tan
The Truth: SPF does not prevent tanning; it prolongs safe sun exposure while reducing damage.
Many believe that SPF 50 or higher will completely stop tanning, but that’s not the case. Higher SPF means better protection from harmful UV radiation, but it does not block 100 per cent of the sun’s rays.
Understanding SPF Levels
SPF 15 blocks 93 per cent of UVB rays.
SPF 30 blocks 97 per cent of UVB rays.
SPF 50 blocks 98 per cent of UVB rays.
SPF 100 blocks 99 per cent of UVB rays.
Scientific Evidence
A review in Photodermatology, Photoimmunology & Photomedicine (2020) confirmed that SPF 30 allows for gradual tanning while significantly reducing the risk of sunburn and cellular damage (Diffey, 2020). This supports the idea that sunscreen does not prevent tanning but enables safer sun exposure.
Myth #3: Tanning Without Sunscreen Is Safer Because It’s Natural
The Truth: Tanning without sunscreen increases the risk of sunburn, premature ageing, and skin cancer.
While it’s true that tanning is the skin’s natural defence mechanism against UV exposure, unprotected tanning damages skin cells. This damage accumulates over time, leading to wrinkles, sun spots, and a higher risk of melanoma.
Why You Should Always Use Sunscreen
Prevents sunburn, which increases the risk of peeling, uneven tans, and long-term damage.
Reduces premature ageing by protecting collagen and elastin, which keep skin firm and youthful.
Lowers skin cancer risk by reducing DNA damage caused by UV radiation.
Helps maintain an even, longer-lasting tan by preventing excessive skin peeling.
Scientific Evidence
According to the British Association of Dermatologists, UV exposure is the primary cause of 80-90 per cent of visible skin ageing, and regular sunscreen use can reduce premature ageing by 24 per cent (BAD, 2019).
Myth #4: Sunscreen Blocks Vitamin D Absorption
The Truth: Wearing sunscreen does not completely stop vitamin D production—you still get enough UV exposure for your body to produce it.
Vitamin D is essential for bone health, immune function, and mood regulation, but you don’t need to skip sunscreen to get it. Studies show that people who wear sunscreen still produce sufficient vitamin D, as some UVB rays penetrate the skin.
Scientific Evidence
A study in the British Journal of Dermatology (2019) concluded that individuals who applied sunscreen daily still maintained adequate vitamin D levels without increased sun damage (Norval et al., 2019).
How to Get Vitamin D Safely
Spend 15-20 minutes outside daily before applying sunscreen.
Eat vitamin D-rich foods such as salmon, eggs, and fortified dairy.
Consider supplements if you have low vitamin D levels.
Myth #5: You Should Skip Sunscreen to Build a “Base Tan”
The Truth: A base tan does not prevent sunburn or protect against UV damage.
Some believe that getting a base tan before a beach holiday will protect against sunburn, but in reality, a tan only provides about SPF 3-4, which is not enough to prevent skin damage.
Scientific Evidence
A study in JAMA Dermatology (2021) found that people who relied on a base tan for protection were still at a high risk of sunburn and increased their long-term melanoma risk (Glazer et al., 2021).
How to Get a Safe, Long-Lasting Tan with SPF
If you want a golden glow without the damage, follow these sun-safe tanning tips.
Use a Broad-Spectrum Sunscreen
Choose SPF 30 or higher for optimal protection.
Look for broad-spectrum formulas that protect against UVA and UVB rays.
Reapply every two hours, especially after swimming or sweating.
Tan in Short, Controlled Sessions
Avoid the strongest UV hours (10 AM - 3 PM) to reduce risk.
Gradually increase sun exposure instead of tanning for long hours.
Shade breaks help maintain an even, long-lasting tan.
Moisturise and Hydrate
Hydrated skin tans better and holds colour longer.
Use aloe vera and vitamin E lotions after sun exposure.
Drink plenty of water to keep skin glowing from the inside out.
Enhance Your Tan with Self-Tanners
Self-tanners provide a bronzed glow without UV exposure.
Look for streak-free tanning mousses or gradual lotions.
Glow B*tch Glow and Bronze Baddie are top picks for a non-orange, natural-looking tan.
The Bottom Line: Can You Tan While Wearing SPF?
Yes, you absolutely can tan while wearing sunscreen. The key is to tan gradually with SPF, allowing your skin to develop colour while staying protected from burns, premature ageing, and serious skin conditions.
Sunscreen is your friend, not your enemy—it helps you achieve a safer, more even tan without compromising skin health. So, slather on that SPF and enjoy the sun the right way!
