7. The Real Reason Why Your Skin Is Breaking Out: An Expert Answers

Changing weather got your skin acting up? Acne’s back to say hello

Inputs by: Dr. Pratik Thacker, Practising Dermatologist at Centre of dermatology excellence

While it might seem counterintuitive, and many people experience a temporary improvement in their acne while in the sun (often due to tanning masking redness or initial drying of the skin), sun exposure can absolutely worsen acne in the long run.

Here's a breakdown of why you might be breaking out after sun exposure:

1. Increased Sebum Production (Rebound Effect):

• Initially, UV rays can dry out the surface layer of your skin.
• In response to this dryness, your sebaceous glands (which produce oil/sebum) go into overdrive to compensate for the lost moisture. This increased sebum production can then clog pores, leading to more blackheads, whiteheads, and inflamed pimples. This is often referred to as the "acne rebound effect".

2. Thickening of the Skin (Hyperkeratinisation)

• Sun exposure causes the top layer of your skin (epidermis) to thicken as a protective mechanism against UV damage.
• This thickening can trap dead skin cells and sebum inside the pores, making it more difficult for them to be shed naturally. This creates a perfect environment for pore blockages and subsequent breakouts.

3. Increased Sweat and Bacteria

• Warm weather and sun exposure lead to increased sweating. Sweat can create a humid environment on the skin, which is ideal for the proliferation of acne-causing bacteria (Propionibacterium acnes).
• When sweat mixes with excess oil, dead skin cells, and any products on your skin, it can further clog pores.

4. Inflammation and Hyperpigmentation

• UV radiation is an inflammatory agent. It can intensify the inflammation associated with existing acne lesions, leading to more redness, swelling, and discomfort.
• For people with acne, sun exposure significantly increases the risk of post-inflammatory hyperpigmentation (PIH). These are the dark spots or marks that linger after a pimple heals. UV rays stimulate melanocytes (cells that produce pigment), making these marks darker and last longer.

5. Compromised Skin Barrier

Excessive sun exposure can weaken the skin's natural protective barrier. A compromised barrier makes your skin more susceptible to environmental irritants and bacterial infections, which can worsen acne and delay healing.

6. Photosensitivity from Acne Treatments

Many common acne medications, both topical (like retinoids and benzoyl peroxide) and oral (like certain antibiotics such as doxycycline and isotretinoin), make your skin more sensitive to the sun. This can lead to severe sunburn, irritation, and even phototoxic reactions, further aggravating your skin and potentially worsening acne.

7. "Solar Comedones"

While distinct from typical acne, prolonged sun exposure can also cause "solar comedones" (also known as Favre-Racouchot syndrome). These are non-inflammatory clogged pores (whiteheads and blackheads) that appear in sun-exposed areas, typically in middle-aged and older adults.

6 Ways to Protect Your Skin From Acne

1. Use Non-Comedogenic Sunscreen: This is crucial. Choose a broad-spectrum sunscreen with an SPF of 30 or higher that is labelled "non-comedogenic" (meaning it won't clog pores) and "oil-free." Mineral sunscreens (with zinc oxide and titanium dioxide) are often a good choice for acne-prone skin. Reapply every two hours, or more often if sweating or swimming.
2. Seek Shade and Limit Exposure: Avoid direct sun exposure, especially during peak hours (10 a.m. to 4 p.m.).
3. Wear Protective Clothing: Hats, sunglasses, and lightweight, long-sleeved clothing can provide additional physical protection.
4. Maintain a Consistent Skincare Routine: Continue to cleanse your face gently twice a day with a mild cleanser, and use your prescribed acne treatments as directed by your dermatologist.
5. Stay Hydrated: Drink plenty of water to keep your skin hydrated from within.
6. Avoid Tanning Beds: These emit harmful UV rays that can damage your skin and worsen acne in the same ways as natural sunlight.

While the sun might offer a temporary illusion of clearer skin, its long-term effects can be detrimental to acne-prone skin. Prioritising sun protection is key to managing breakouts and maintaining overall skin health. If you're struggling with persistent acne, consulting a dermatologist is always recommended.
