The Myth of the Monsoon Sky
The biggest mistake people make during the monsoon is assuming that cloudy skies mean no sun damage. While clouds do block a significant amount of visible light and heat, they are far less effective at blocking harmful ultraviolet (UV) radiation. In fact,
dermatologists confirm that up to 80% of UV rays can penetrate through cloud cover and reach your skin. These rays are the primary culprits behind premature ageing, pigmentation, and long-term skin health risks. There are two main types of UV rays to worry about: UVB, which causes burning, and UVA, which is responsible for ageing. Clouds block some UVB, which is why you're less likely to get a sunburn on a gloomy day. However, UVA rays, which make up about 95% of the UV radiation reaching Earth, pass through clouds and even window glass with ease, causing damage year-round. This is why consistent protection is non-negotiable, rain or shine.
Check 1: Broad-Spectrum Protection (UVA + UVB)
The first thing to check on any sunscreen label is the term “broad-spectrum”. This is your guarantee that the product protects against both UVA and UVB rays. An SPF number (Sun Protection Factor) only measures protection against UVB rays, the kind that cause sunburn. Without broad-spectrum coverage, you're leaving your skin exposed to UVA rays, which penetrate deeper to break down collagen, cause fine lines, and contribute to hyperpigmentation. In India, you will often see a PA rating on sunscreens, usually with plus signs (e.g., PA+++). This system, originating from Japan, specifically measures the level of UVA protection. For the best defence, especially for Indian skin prone to pigmentation, look for a broad-spectrum sunscreen with a rating of PA+++ or the highest available, PA++++.
Check 2: The Right SPF for Cloudy Days
While you might not need the absolute highest SPF on an overcast day, dermatologists still recommend a minimum of SPF 30 for daily use. An SPF 30 blocks approximately 97% of UVB rays. For more robust protection, especially given the Indian climate, opting for SPF 50 is a widely recommended choice. An SPF 50 provides a higher margin of safety, which is useful because most people don't apply a thick enough layer of sunscreen to achieve the full protection stated on the bottle. So, for daily commutes and incidental exposure during the monsoon, a broad-spectrum sunscreen with at least SPF 30-50 is the ideal choice.
Check 3: A Monsoon-Proof Formula
The high humidity, sweat, and occasional downpours of the monsoon season demand a specific type of sunscreen formula. Texture is everything. Heavy, creamy sunscreens can feel sticky and greasy in the humid air, leading to clogged pores and breakouts. Look for products that are labelled “water-resistant” or “sweat-resistant”. According to regulations, this means the sunscreen maintains its SPF level for a specified time (either 40 or 80 minutes) in water. For the Indian climate, lightweight gel-based or fluid formulas are often the most comfortable. These absorb quickly without leaving a heavy film. Also, seek out sunscreens that are “non-comedogenic,” meaning they are specifically formulated not to clog pores—a crucial feature when the air is already damp and sticky.
Check 4: Your Skin Type Still Matters
Finally, the best sunscreen is one that works for your specific skin type. During the monsoon, skin behaviour can change. Oily and acne-prone skin types should prioritise gel-based, oil-free, and matte-finish sunscreens to avoid excess shine and breakouts. Look for ingredients like niacinamide, which can help regulate oil production. For those with dry skin, a cream-based or lotion sunscreen with hydrating ingredients like hyaluronic acid or glycerin might still be necessary to prevent the skin from feeling tight. If your skin is sensitive, a mineral sunscreen containing zinc oxide or titanium dioxide may be a gentler option, as these ingredients form a physical barrier on the skin and are less likely to cause irritation.
