Can Sunburn Cause Pimples? And What to Do About It

Sunburn can lead to pimple development, a common experience where skin overexposed to the sun subsequently breaks out. Understanding the connection between sun damage and skin blemishes can help in managing and preventing such occurrences.

How Sunburn Can Lead to Breakouts

Sunburn occurs when ultraviolet (UV) radiation from the sun damages the outermost layers of the skin, triggering an acute inflammatory reaction. This damage initiates a chain reaction of cellular stress within the skin. UV exposure leads to increased production of free radicals, which contribute to inflammation and can worsen existing skin conditions.

The skin’s response to UV damage often includes a drying effect, even on oily skin. When the skin becomes excessively dry, sebaceous glands may go into overdrive, producing an increased amount of sebum to compensate for the moisture loss. This excess oil, known as seborrhea, is a factor in the formation of blemishes.

UV rays also cause skin thickening, a process called keratinization. This thickening makes it more challenging for dead skin cells to shed naturally from the surface. When dead skin cells accumulate and combine with excess sebum, they can block hair follicles, creating an environment where pores become clogged. Additionally, increased sweat production in warm, sunny conditions contributes to a favorable environment for blemish-causing bacteria to thrive, further exacerbating the likelihood of breakouts.

Identifying Sunburn-Related Pimples

Pimples that appear after a sunburn usually appear as small red bumps or whiteheads. These blemishes typically develop within a few days following sun exposure. They are most common in sun-exposed areas like the face, shoulders, and back.

Distinguishing these from typical acne involves noting their timing and distribution. While chronic acne can appear anywhere and persist, sunburn-induced pimples are a direct, acute response to UV radiation damage. Other post-sunburn issues like peeling or dryness can occur, but distinct pimples indicate a specific inflammatory reaction. Sometimes, sun sensitivity can also cause acne-like eruptions, such as polymorphous light eruption (PMLE), which presents as various forms of rash, including raised spots or blisters.

Caring for Sunburned Skin with Breakouts

Managing skin with both sunburn and breakouts requires a gentle approach to avoid further irritation. Wash affected areas with a mild cleanser and lukewarm water. Avoid harsh soaps, scrubbing, or exfoliants, as these can aggravate irritated skin.

Apply a non-comedogenic moisturizer to soothe and hydrate skin. Products with aloe vera can provide relief and support the skin barrier. Stay well-hydrated by drinking plenty of water, as sunburn can lead to fluid loss.

Temporarily discontinue active skincare ingredients like retinoids, alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), salicylic acid, or benzoyl peroxide on sunburned skin until it heals. If sunburn is severe (large blisters, intense pain, fever, chills) or shows signs of infection (pus, increasing redness), seek medical advice.

Preventing Sunburn and Breakouts

To prevent sunburn-related breakouts, consistently practice sun protection. Use a broad-spectrum sunscreen with an SPF of 30 or higher, protecting against UVA and UVB rays. Opt for non-comedogenic and oil-free formulations to prevent pore clogging.

Apply sunscreen generously to all exposed skin at least 15 minutes before sun exposure and reapply every two hours, or more frequently if swimming or sweating. Seeking shade, particularly during peak sun hours (10 a.m. to 4 p.m.), significantly reduces UV exposure. Wearing protective clothing (long-sleeved shirts, pants, wide-brimmed hats) offers physical barriers against harmful UV radiation. Be aware that certain acne medications can increase skin sensitivity to the sun.
