When it comes to skin care, we put a lot of emphasis on why you should wear sunscreen to protect yourself from harmful UV rays; however, we frequently overlook one area of skin that is more delicate and vulnerable to sun damage than almost any other area: our lips. So, can you put sunscreen on your lips?

So, can you put sunscreen on your lips?
Lips are the bodyβs most sensitive sensory organ and a mainstay of our face. Studies show that the lips are one of the first and most prominent areas that show signs of aging- starting with gradual loss of volume and increased lines that accumulate as time goes on.1 Not only that, but lips are built differently, lacking many protective features compared to the rest of skin. The truth is, protecting the skin on your lips is crucial, and it is essential to incorporate a lip sunscreen or application of regular sunscreen with SPF into your routine.
In this blog we will explore the importance of applying sunscreen to your lips for sun protection, while also providing practical tips for keeping your lips safe from harmful UV rays. Weβll discuss the potential risks of sun exposure to the lips and why using sun protection on them is a step that should never be overlooked.

How is lip skin different?
We know the skin on our lips is much more delicate and prone to sun damage than the rest of our body, but why? To start, our lips are covered by a much thinner layer of skin compared to the rest of our face or body. They have a thin stratum corneum (the outermost layer of the epidermis
), which serves a protective function, prevents dehydration, and shields UV radiation.2 Additionally, this exceptionally thin layer of skin lacks melanocytes, which contain the melanin pigment found across the rest of the body. The lip skin also has a higher transepidermal water loss (TEWL) and lower water content than skin on the cheeks, primarily due to the fact that lip skin doesnβt produce sebum.4 Being that their only source of moisture is saliva, the lips can easily become dry, chapped, and more prone to sunburn.

Why lips need sun protection
UV damage can cause premature aging, and more importantly, leads to an increased risk of skin cancer. The fact is that the natural differences between the skin on the lips as opposed to the rest of the body means that lips are extra susceptible to UV damage and environmental stressors. Letβs delve a bit deeper into why lips need sun protection:
The lips have an inherently weaker
skin barrier
They have no oil glands! This leads to a lack of sebum, which contains antioxidants to help manage free radicals caused by UV radiation. Sebum also provides essential moisturization to the rest of your skin- without it, the lips are much more prone to dehydration.
Melanin acts as your body's natural defense against UV radiation, absorbing and dissipating harmful UV rays.3 Since the lips have less melanin, they are more susceptible to the damaging effects of UV radiation.
In order to make up for the lipβs vulnerabilities, we should be applying SPF to lips diligently. Cumulative UV damage from unprotected sun exposure, smoking, and other lifestyle habits play a role in lips' loss of volume, wrinkled appearance, and weakened color.
due to a thin stratum corneum, this means there is less natural protection against the sunβs harmful UV rays that are inherent to thicker areas of skin.
Of these, UV damage is thought to be the most destructive and the leading extrinsic aging factor to the lips.5 But perhaps the most critical reason to protect your lips from the sun is to reduce the risk of skin cancer. Prolonged and repeated sun exposure increases the likelihood of developing cancers like squamous cell carcinoma on the lips,6 which can be aggressive and challenging to treat.

What ingredient can you use on your lips?
When it comes to choosing the right sunscreen or SPF lip balm, look for products that contain these protective ingredients:
Broad-Spectrum SPF - Ensure that the product offers broad-spectrum protection, which shields against both
UVA rays and UVB rays
Mineral sunscreen - Zinc oxide and titanium dioxide are mineral sunscreen ingredients that provide a physical barrier against UV radiation.8 Of the two
zinc oxide is our preferred mineral UV filter, because it provides superior protection that is sustainable and gentle on the skin. Current evidence suggests that mineral sunscreens
Antioxidants - Look for a lip product that contains antioxidants like vitamin E or green tea extract.
Antioxidants
Moisturizing Ingredients - To prevent water loss, try to stay hydrated and lock in that hydration by using
topical products like a peptide cream
. This comprehensive coverage is essential for effective sun protection.
are also potentially safer for your skin compared to chemical sunscreen filters- this is especially important for products you could potentially ingest, like lip sunscreen.
help neutralize free radicals generated by UV radiation, offering an additional layer of UV protection. This is especially important for lips, since they are not able to create sebum, which naturally contains antioxidants.
with moisturizing ingredients like shea butter, coconut oil, or beeswax. These ingredients help prevent dryness and chapped lips.
