The Science Behind Weather and Climate
As we go about our daily lives, we often find ourselves taking the weather for granted.
Whether it’s the gentle warmth of the sun on our skin or the refreshing coolness of a summer rain, weather plays a significant role in shaping our experiences.
But what exactly is happening in the atmosphere to create these conditions? Understanding the science behind weather and climate can enrich our appreciation of the world around us and perhaps even guide us in making more mindful choices in our lives.
Sunscreen is an essential component of skin health, yet individuals with acne-prone or oily skin sometimes worry that it may worsen breakouts. Acne develops when excess sebum combines with retained dead skin cells inside the follicle, forming clogged pores that can progress into blackheads, whiteheads, and inflammatory lesions. Sunscreen itself does not directly cause acne, but certain formulations may contribute to pore congestion in susceptible individuals if they are heavy, highly occlusive, or difficult to remove.
Many traditional sunscreens were formulated with thicker emollients to enhance water resistance and durability. In acne-prone skin, these heavier textures may trap sebum and debris against the surface, potentially increasing the likelihood of clogged pores. Incomplete cleansing at the end of the day can further contribute to buildup. However, modern sunscreen formulations are often labeled non-comedogenic and designed specifically for oily or acne-prone skin types. These products typically use lighter vehicles that absorb more readily and reduce the sensation of greasiness.
Both mineral and chemical sunscreens can be suitable for acne-prone skin, depending on the overall formulation. Mineral filters such as zinc oxide are sometimes preferred by individuals with sensitive or reactive skin because they may be less irritating. However, mineral sunscreens can feel thicker if not carefully formulated. Chemical filters tend to be lighter in texture but may cause irritation in some users, which can indirectly worsen inflammatory acne if the barrier becomes compromised. Irritation, rather than the sunscreen itself, is often the factor that contributes to flare-ups.
When selecting a sunscreen for acne-prone skin, lightweight gel, fluid, or lotion textures may be more comfortable than dense creams. Products labeled oil-free or non-comedogenic are often better suited for those concerned about clogged pores. Ingredients such as niacinamide may provide additional support by helping regulate visible oiliness and supporting barrier function. Avoiding strongly fragranced formulations may also reduce the risk of irritation.
Proper cleansing plays an important role in preventing sunscreen-related congestion. A gentle cleanser used once or twice daily is usually sufficient to remove daily sunscreen without over-stripping the barrier. Over-cleansing or aggressive scrubbing can increase inflammation and worsen acne. For individuals who wear water-resistant or long-wear sunscreen, thorough but gentle cleansing in the evening may reduce residue buildup.
It is also important to recognize that unprotected sun exposure can worsen post-inflammatory hyperpigmentation and delay the healing of acne lesions. Certain acne treatments, including retinoids and exfoliating acids such as salicylic acid, may increase photosensitivity. Skipping sunscreen can therefore compromise overall treatment progress.
Sunscreen does not inherently worsen acne, but formulation choice and cleansing habits matter. Selecting a lightweight, non-comedogenic product and maintaining barrier-supportive skincare can help minimize the risk of clogged pores. Individuals experiencing persistent breakouts despite careful product selection may benefit from consultation with a qualified healthcare professional to evaluate their skincare routine and treatment plan.
