How Blemished Skin Can Benefit From Sunblock


Is sun exposure really all that bad?

UV rays have been at the centre of many cautionary tales told by dermatologists, doctors and aestheticians. Skincare experts and enthusiasts alike warn of the potential damages to our skin if we stay outdoors for too long. In this article, we examine the pros and cons of sun exposure and share tips on how to find the best sunscreen for acne.


Pros And Cons Of Sun Exposure 

Sun exposure is actually important for health reasons.

It is a natural source of Vitamin D. When sun rays come into contact with your skin, it stimulates our body to produce Vitamin D. A healthy amount of sun exposure is essential to maintain a healthy complexion as we may not always get enough Vitamin D from our daily diet.

Vitamin D delivers the following health benefits:

-Stronger teeth and bones

-Reduction in high blood pressure

-Improved brain function

-Better sleep quality

On the flipside, overexposure to sun rays by staying out in the sun too long or without the protection of a sunblock can have the following negative impacts on your complexion. 

-Painful sunburns and damaged skin barrier

-Increased skin sensitivity

-Premature aging in the form of fine lines and wrinkles

-Pigmentations in the form of freckles, dark spots and discoloration

-Loss of skin elasticity and firmness

-Aggravated existing skin condition such as acne

-Elevated risk of developing skin cancer


Why Using A Sunblock Is Important

1. Prevents Aggravation Of Existing Skin Condition 

Acne-prone skin are more susceptible to external stressors such as harsh sunlight. Without the protection of a sunblock against UVA and UVB rays, sunburns can worsen inflamed pimples. Prolonged sun exposure can weaken skin barrier and cause the walls of your pores to break down which impede your skin’s healing process.


2. Protects Against Photosensitivity

Certain potent acne-fighting ingredients can cause photosensitivity. Acne ingredients, such as Retinol and exfoliating acids, and even prescription medication like Accutane, are known to induce skin sensitivity to light. As explained by dermatologist Dendy Engelman, “Using acne medication like Retinol can make the skin sensitive to the sun. People with acne have the potential to develop post-inflammatory hyperpigmentation. Sun exposure can make this worse and increase the potential of having the pigment last much longer than it would otherwise.”


3. Inhibits Photoaging

Photoaging is a phenomenon where people develop signs of premature aging due to excess exposure to the damaging effects of sun rays. Using a sunblock helps to prevent the formation of early onset wrinkles, discoloration and fine lines.


What To Look Out For When Buying Sunblock For Acne Skin

Here is a checklist of all the important considerations when it comes to choosing a sunscreen for skin prone to breakouts.


  • Lightweight

A lightweight sunscreen is best for tropical climates. Sunscreens with a gel-like texture or water-based formulations are quickly absorbed and will not feel greasy under heat. Reapply whenever you need to during the day without the uncomfortable sensation of heaviness.  


  • Mineral Sunscreen

Chemical sunscreens contain ingredients that are absorbed into the skin. With acne-prone skin, you would want to have as little interference with your complexion as possible. Instead, opt for a mineral sunscreen that is designed to sit on top of your skin to deflect and scatter UV rays.


  • Non-Comedogenic Formulation

Sunscreens labelled as non-comedogenic do not clog your pores which reduces the likelihood of triggering a breakout. If possible, avoid artificial fragrances in your sunscreen as well.


  • Protection Level

The Sun Protection Factor (SPF) indicates the level of defence against UVB rays, while the PA rating signals the level of protection against UVA rays. For daily regular use, use a sunscreen with at least SPF 30 protection. If you will be outdoors for an extended period of time, go for one with a higher SPF protection.


While prolonged sun exposure can lead to negative side-effects on your skin, it doesn’t mean that you should be hiding indoors all the time. With adequate sun protection from a sunscreen suitable for acne-prone skin, you can enjoy your time out in the sun to get your daily dose of Vitamin D!
