Can You Tan with Sunscreen? Myths Busted & Facts Revealed!

The use of sunscreen is a common practice for those wishing to protect their skin from the harmful effects of the sun’s ultraviolet (UV) radiation. However, there is a prevalent question on many sun-seekers’ minds: Can you still get a tan with sunscreen? 

This question can be unpacked by understanding how sunscreen works and what SPF (Sun Protection Factor) means, particularly when considering common SPFs like 30 and 50.

Sunscreen and How It Works

Sunscreen is designed to decrease your skin’s exposure to UV rays, which come in two primary forms relevant to skin health: UVA and UVB. UVA rays penetrate deep into the skin and are primarily responsible for aging and long-term skin damage, while UVB rays affect the outer skin layer, causing sunburn and playing a significant role in developing skin cancer.

There are two main types of sunscreen: chemical and physical. Chemical sunscreens absorb UV rays before they can damage the skin, while physical sunscreens (containing minerals like zinc oxide or titanium dioxide) reflect UV rays away from the skin. Both types aim to minimize the skin’s exposure to harmful UV radiation.

Understanding SPF

SPF is a measure of how much UV radiation is required to cause sunburn on protected skin relative to the amount of UV radiation required to cause sunburn on unprotected skin. For instance, if it takes 30 times longer to burn with sunscreen than without it, the product is rated as SPF 30. However, it’s crucial to note that SPF ratings apply only to UVB radiation, the primary cause of sunburn, not UVA.

Can You Still Get Tan with Sunscreen?

Yes, you can tan with sunscreen, although the extent of tanning may be reduced. Sunscreen is designed to protect against sunburn, not to completely block all UV radiation. A tan results from the skin producing more melanin after exposure to UV radiation, indicating skin damage. 

So, when you tan while using sunscreen, it implies that some UV rays are still penetrating your skin, albeit in lesser amounts than if you weren’t wearing sunscreen.

Can You Tan with Sunscreen SPF 30?

Using sunscreen with SPF 30, you can still tan, but it will likely be slower and less intense than without protection.

Sun Protection Factor (SPF) is a measure of how well a sunscreen will protect skin from UVB rays, the kind of radiation that causes sunburn and contributes to skin cancer. An SPF 30 sunscreen allows about 1/30 of the UVB rays to reach your skin, blocking out approximately 97%. 

A person using SPF 30 can stay in the sun 30 times longer without burning than they would without protection. Consequently, while you can still tan with SPF 30, it’s a gradual process that affords the skin considerable protection against the most harmful effects of sun exposure.

Can You Tan with Sunscreen SPF 50?

Similarly, with sunscreen SPF 50, tanning is possible, albeit at a slower pace. 

Elevating the SPF to 50 increases the amount of UVB filtration to about 98%. Although the difference in UVB protection between SPF 30 and SPF 50 is relatively marginal, it does enhance safety against sun damage.

The protective layer offered by SPF 50 means that the skin absorbs even fewer UV rays, reducing the risk of sunburn and long-term skin damage more significantly than an SPF 30 might.

Factors That Affect Tanning with Sunscreen

Tanning with sunscreen is not solely about the product’s SPF rating; it also depends on several critical factors, including how one applies and uses the sunscreen.

Proper Application: Sunscreen must be applied generously and evenly. Most people apply less than half of the amount required to achieve the SPF indicated on the label.

Reapplication: Sunscreen should be reapplied every two hours or after swimming, sweating, or towel drying to maintain its protective effect.

Intensity of Sun Exposure: The time of day and location can affect the intensity of UV rays. Near the equator, during midday, or at high altitudes, UV radiation is stronger.

Type of Sunscreen: Broad-spectrum sunscreens protect against both UVA and UVB rays, reducing the likelihood of tanning and skin damage.

Individual Skin Type: Some skin types tan more easily than others. People with more melanin in their skin naturally have some protection against UV radiation and may tan more readily, even with high SPF sunscreen.

Degradation of Sunscreen: Over time, especially in direct UV light, the protective ingredients in sunscreen can break down, reducing effectiveness.

Implications of Tanning with Sunscreen

Tanning with sunscreen is a common practice, but it’s a misconception that it’s a safe way to achieve a bronzed look. Even with sunscreen, tanning indicates skin damage, as no sunscreen can block 100% of UV rays. The idea of a “healthy tan” is a myth; a tan is actually your skin’s distress signal, revealing DNA damage from UV exposure. Sunscreen should be used to minimize the risk of burns and damage, not to prolong sun exposure for tanning purposes.

The long-term effects of tanning include premature aging and an increased risk of skin cancer, conditions linked to UV-induced DNA damage in skin cells. As your skin darkens, it’s showing that melanocytes are trying to protect your DNA from UV damage, but this defense is not foolproof. A darker skin color after sun exposure, even with sunscreen, usually means there’s been some level of harm.


In conclusion, while sunscreens with SPF 30 and SPF 50 provide high levels of protection against UVB rays and reduce the risk of skin damage, they do not completely eliminate the possibility of getting a tan. Their primary function is to minimize the risk of sunburn and long-term skin damage, including skin cancer. 

Therefore, while tanning with sunscreen is possible, it should not be the goal. The most responsible message for skin health is to embrace your natural skin tone, use sunscreen for protection, and understand that any change in skin color.
