Dermatologist-Recommended Brightening Lip Balms for Summer

Ever noticed dark brown patches on your lips? Or a sun- moustache- like shadow on your upper lip? It’s more common than you think. 

 

Summer sun may be amazing for vacations, but not so much for your lips.

Did you know your lips have significantly more thinner layers than your face? So protecting them from sun-exposure becomes all the more necessary.   

Due to sun-exposure, your body triggers melanin production as a defence mechanism against UV. This is why your lips may become darker, especially during Indian summers. 

Many lip balms may promise hydration but may not protect you from sun-damage or brighten your pigmented lips.  A truly effective lip balm should offer you broad-spectrum protection, hydration and brighten dark spots and treat pigmentation on your lips. 

Summer is crawling right around the corner, so is lip pigmentation due to UV exposure! 

Don’t sweat it though, we’ve got you covered with this expert guide offering you: Dermatologist recommended picks, ingredients insights and  evidence-backed, brightening lip balms for the upcoming summer so you can beat not just the heat, but also sun-induced lip pigmentation. 

So, Why Do Your Lips Get Darker in Summer?

Here’s a dermatological- insight into why you may notice your lips darkening during the summer. 

UV Exposure and Melanin Production 

Your lips are significantly thinner than your skin. Your normal skin contains up to 16 layers while the skin on your lips have only 3-6 layers. Added to this, due to the lack of hair follicles and sebaceous (oil producing) glands on the lips offer no natural protection against UV radiation. Lips cannot moisturise themselves so they are more vulnerable to chapping and sun-damage.

UV rays also trigger lip hyperpigmentation. Here’s how: 

UV exposure triggers melanocytes (melanin- producing cells) in your lips. This is your body’s natural defence against UV.  But this is what causes darkening of the lips and may develop into lip hyperpigmentation (Source: National Library of Medicine). 

Other Causes of Lip Darkening: 

1. Smoking: Nicotine & tar stain the outer lip tissue and constrict blood vessels, reducing oxygen flow to the lips. The heat also triggers melanocytes causing darkening and lip hyperpigmentation. 

2. Dehydration: The lack of sebaceous glands causes the lips to dry out easily without proper water intake. This can lead to inflammation in the lips and flaking which make your lips appear darker and duller. 

3. Matte Lipsticks: The formulas in matte lipsticks are highly drying and contain pigments that stain the skin on your lips easily. Low quality makeup may contain heavier metals like lead that makes this problem worse. 

4. Allergic reactions: Sensitivity or allergy to certain fragrances, preservatives or dyes in lipsticks may lead to post-inflammatory hyperpigmentation or PIH. (Source: National Library of Medicine).

5. Vitamin Deficiencies: Vitamin deficiencies like Vit B3 (primarily), Iron (anemia), folate, Vit C and E cause uneven tone, dryness, inflammation leading to  darkening of the lip, leading to lip hyperpigmentation. 

6. Excessive sun exposure: As UV rays trigger melanin production to absorb radiation. Since lips naturally have a lower melanin content, they are especially prone to darkening or hyperpigmentation. 
   

 

What Makes a Lip Balm “Brightening?”

A brightening balm doesn't work by bleaching your lips. A truly effective brightening lip balm targets the pigment production and supports lip barrier repair. 

Don’t just choose a lip balm for dark lips. You need to care about what goes into your lips. 

Here is an ingredient breakdown to help you know what you are putting onto your lips as we give you a closer look into what makes a lip balm “brightening” 

We’re not here to convince you, we are here to educate you! 

Proven Brightening Ingredients:

Dermatologists advice using clinically active ingredients such as: 

Vitamin C (Ascorbyl Palmitate)

A fat soluble version of Vitamin C that is more stable and absorbs better as opposed to normal water-soluble versions. This acts as a potent antioxidant, neutralising free radicals that trigger melanin production.

Niacinamide (Vitamin B3)

Known as the “multitasker” ingredient in the dermatology field, it blocks the transfer of melanocytes (pigment producing cells) from deeper skin cells to the surface. It simultaneously boosts ceramide production in the skin, strengthening and repairing the lip barrier. Niacinamide protects your lips from dehydration induced darkening.

Licorice Extract

It contains a compound called Glabridin, a natural skin-whitening agent. It is a gentle yet powerful tyrosinase inhibitor (the enzyme responsible for creating pigment in your skin)

By lowering melanin levels, it helps reduce dark spots caused by UV exposure (lip hyperpigmentation). 

Kojic Acid

This natural ingredient is derived from a certain fungi during the fermentation process. It inhibits the enzyme called tyrosinase which is involved in melanin production in the skin. It is gentle on your lips and promotes cellular regeneration. 

Alpha Arbutin 

This gentle and natural ingredient can effectively inhibit melanin production. It targets dark spots caused due to sun damage, smoking or dehydration. 

Proven Hydrating Ingredients:

Shea Butter

Shea butter is rich in fatty acids that act as a natural moisturiser for the lips, forming a protective barrier over the skin helping it retain moisture and restoring your lips. It has anti-oxidant properties that protect the lips from environmental damage and sun-induced damage. Although this ingredient by itself protects your lips from a certain level of the sun’s UV- damage, you should use it with a dedicated SPF sunscreen for the best protection. 

Hyaluronic Acid

This highly effective ingredient is the most popular ingredient for hydration. It is known to hold up to 1000 times it’s weight in water. It acts as a humectant (moisture magnet) by drawing water into the skin, almost like a sponge.  It keeps your lips hydrated, improves overall lip texture and lip health. 

Ceramides

This ingredient acts as the “glue,” to repair, restore and protect your lips. They act as a restoration-agent,  seal in moisture and prevent transepidermal water loss (TEWL), or loss of moisture from the skin’s surface caused by evaporation. They create a protective film over the lips, keeping your lips hydrated for longer periods. 

Squalane

This ingredient offers hydration, barrier protection and antioxidant support (Source: Clinikally). It mimics the skin’s natural sebum. It is lightweight and non-greasy in texture and absorbs quickly into your lips. 

Why SPF is non-negotiable in summer

While many of us know the importance of applying sunscreen on our face and body, most of us forget that our lips need all the more protection. If you’re battling the Indian heat, you need an equally strong SPF broad spectrum lip balm to protect your lips from the harsh Indian climate. 

The skin on your lips lack natural melanin and are thinner than the skin on your face.
Studies report that due to their thinner layer, lips are particularly vulnerable to sun damage. (Source: MDPI) and UV- induced hyperpigmentation. 

So here are some non-negotiables while choosing an SPF lip balm in summer:

• Choose an SPF lip balm of 15-30  minimum. 

•  Broad-spectrum protection (UVA+UVB) protection 

• A lip balm with mineral filters like Zinc oxide (highly photostable and does not degrade as rapidly under UV exposure, as opposed to chemical filters)

• Dermatologists recommend reapplication every two hours for effective protection against UV.

How to Use Brightening Lip Balm for Maximum Results

To ensure you're protecting your lips the right way, here is a quick go-to-guide. 

• Apply your SPF lip balm 15 minutes before sun exposure

• Reapply every two hours

• Use a gentle lip scrub once or twice a week to gentle exfoliate your lips and improve cell turnover

• Avoid licking your lips as they contribute to dehydration-induced darkening  

• Use an overnight lip balm to aid lip repair while you're asleep! 

Although lip pigmentation cannot be reversed permanently, a brightening lip balm with SPF can help prevent further tanning and melanin production in the lips and brighten them over time.

 

 With a dedicated routine and consistent use, visible results for using an SPF lip balm can be expected anywhere around 4 - 8 weeks. Significant visible brightening can be seen typically around 2-3 months.

Common Mistakes That Worsen Lip Pigmentation

Even the best brightening SPF lip balm can’t deliver results if certain everyday habits continue to trigger pigment production. 

 Here are some mistakes that are more common than you think, that may be worsening your  lip pigmentation:

• Using matte lipsticks daily is a recipe for disaster. These formulas are known for sucking the moisture out of your lips. The chronic dryness leads to micro-cracks and inflammation, worsening post- inflammatory lip hyperpigmentation (PIH). 

• Skipping SPF is the #1 factor. Especially if you spend a lot of time outdoors in activity or commutes. 

 If you skip SPF during the day, yet use a brightening lip balm at night, it becomes counter-productive. 

• Seeing too many DIY lemon remedies that promise to lighten your lips? Don’t fall for it. In reality they have high acidity levels that may irritate your skin, often worsening your lip pigmentation. 

• Over-exfoliating or scrubbing your lips too harshly will often damage your lips’ delicate barrier and cause trauma to your lips. This will signal your body to produce more melanin as a trauma response. 

• A significant cause or worsen lip pigmentation is smoking. 

Final Thoughts: Choosing the Right Lip Balm for Your Needs

Guess what?  The best brightening lip balm may not actually be the right one for you. 

Remember to choose a brightening lip balm that suits your daily routine and skin type and formulations with brightening ingredients that are scientifically proven to actually work. 

Here’s a quick summary for your easy reference. 

For sensitive skin - use mineral filter SPF lip balms (Zinc Oxide/ Titanium Dioxide) that do not irritate your skin unlike chemical filters

For an active/outdoor lifestyle dermatologists recommend SPF 50+ with broad-spectrum protection, warranting a higher level of protection. SPF 30+ is deemed sufficient for daily use by dermatologists. No matter the SPF of the lip balm, reapply every two hours. 

Don’t just go for lip balms that promise lip lightening. Choose a lip balm that targets the root cause for it. For dark or pigmented lips - look for ingredients like Vitamin C or Niacinamide for targeted and effective pigmentation treatment

For daily use- It is recommended to use a hydrating +SPF combo to protect, hydrate and prevent damage or darkening of the lips during the day and night for an all-round protection.
