The benefits of sun creams in the fight against acne!
The idea that the sun can improveacne is widespread. However, the apparent benefits of sun exposure on acne are often short-lived and can mask long-term negative effects. In this article, we'll explore in detail the sun's true impact on acne, and why proper protection is essential for your skin's health.
Sun and Acne: A False Good Idea
The temporary effect of UV rays
It is often observed that exposure to the sun dries out the skin, temporarily reducing sebum production and diminishing the appearance of acne pimples. Skin tanning, a natural protective response to UV rays, thickens the epidermis, masking redness and imperfections.
However, this improvement is only superficial and temporary. Ultraviolet (UV) rays induce skin changes that may appear beneficial in the short term, but are in fact deceptive.
The rebound effect
After prolonged exposure to the sun, the skin reacts by increasing sebum production to compensate for the initial dryness. This reactive hyperseborrhea is often followed by clogged pores, as thickened skin blocks the natural outflow of sebum. This creates an environment conducive to the proliferation of acne-causing bacteria, leading to a resurgence of acne flare-ups after sun exposure.
Cellular damage and other risks
Prolonged exposure to UV rays doesn't just aggravate acne. It also damages the DNA of skin cells, increasing the risk of skin cancers such as carcinoma and melanoma. What's more, UV rays accelerate the skin's aging process by degrading the skin's fibers. collagen and elastin, leading to the premature appearance of wrinkles and age spots.

Hyperpigmentation and Acne Scars
The sun's impact on scars
Visit acne scarsAcne scars, particularly post-inflammatory scars, are sensitive to UV rays. Exposure to the sun causes hyperpigmentation, as skin damaged by acne pimples produces more melanin to protect itself. This overproduction of melanin makes scars darker and more visible, making their treatment more complex.
The phenomenon of post-inflammatory hyperpigmentation
Post-inflammatory hyperpigmentation (PIH) is the skin's natural response to inflammation or injury. Dark-skinned people are particularly prone to this phenomenon. UV rays, making marques even more pronounced and persistent. So it's crucial to protect these vulnerable areas with a sun protection to avoid increased pigmentation.
Photosensitizing anti-acne treatments
Caution with certain treatments
Visit retinoids and benzoyl peroxide, commonly used to treat acne, increase the skin's sensitivity to UV rays. By reducing the skin's stratum corneum, these substances make the skin more vulnerable to sunburn. What's more, the drying effect of these treatments can exacerbate the damage caused by UV rays. It is therefore essential to apply these treatments in the evening, and to use effective sun protection during the day.
Choosing the right sun protection
Why sun protection is crucial
To prevent the sun's harmful effects, it's imperative to use a sunscreen offering broad-spectrum protection, covering both UVA and UVB rays. UVA rays penetrate deep into the skin and are responsible for skin ageing and cancer, while UVB rays cause the most serious sunburns. sunburn and burns.
The importance of non-comedogenic products
For acne-prone skin, choosing a non-comedogenic sunscreen is essential. The products comedogenic can clog pores, aggravating acne. Choose light, non-oily formulations that won't add extra oil to the skin. Sunscreens containing soothing and moisturizing ingredients, such as hyaluronic acid and aloe vera, can help keep skin hydrated without clogging pores.
While sun exposure can temporarily improve the appearance of acne, the long-term effects are often deleterious. Between the rebound effect and cell damage, it's crucial to protect your skin with appropriate sunscreen and limit exposure to UV rays. Take care of your skin with suitable products and avoid temporary solutions that could worsen your condition in the long term.
