5 Skincare facts you didn't know you needed

Beauty is often associated with products, treatments and trends, but some of the most valuable lessons have nothing to do with the latest launch. Between TikTok beauty hacks and celebrity-approved routines, it's easy to forget that understanding how your skin and hair function is just as important as the products you use. Ahead, we share a few surprising skincare facts that might change the way you approach your overall beauty routine.

Skincare goes beyond the jawline

You've probably heard beauty experts say that skincare should extend down to your neck, but many dermatologists take it a step further: your skincare routine should continue all the way to your chest. But why? The skin on your neck and chest has fewer sebaceous glands, meaning it ages much faster and loses moisture quickly. Always extend any serums and moisturizers down to your décolletage (the exposed area of the neck, shoulders, and upper chest).

Skin "learns"

The skin adapts to its environment and the active ingredients applied to it. As tempting as it may be to try every trending product, switching products too frequently can confuse your skin and cause breakouts. A consistent routine typically takes the length of an average skin cycle of 28 days when you're in your 20s and 35 to 40 days when you're in your 30s and 40s.

Scalp ages too (faster than the skin on your face)

Many people invest heavily in skincare while neglecting the scalp entirely. However, the scalp is skin too, and it experiences ageing, dryness and environmental damage just like the rest of your body. Because it's hidden beneath hair, it's often overlooked in daily anti-ageing routines, leaving it exposed to environmental stressors such as UV rays, pollution and free radicals. This is why scalp-focused treatments have become one of beauty's fastest-growing trends.

@thedavisstandard You need to treat your scalp like your face because the scalp ages like your skin. And when scalp health declines with age, it can disrupt the hair growth cycle leading to thinning, shedding, and loss of density. After consistently using @One Skin OS-01 HAIR for over a year, I noticed my hairline looking fuller, healthier, and thicker over time. What I love most is how easy it is to stick to the routine because consistency really matters with hair care. The formula is lightweight, water-based, non-greasy, and gentle on sensitive scalps. If you’re experiencing postpartum, menopausal, or age-related hair thinning, this is definitely worth looking into. #OneSkinPartner #OS01HAIR #AgingHair #HairDensity #HealthyScalp ♬ original sound - Thedavisstandard

SPF is necessary in winter and indoors

One of the biggest beauty misconceptions is that sunscreen is only needed during summer. In reality, ultraviolet rays are present year-round, even on cloudy days, which means your skin remains vulnerable to sun damage regardless of the season. And if you think you're safe indoors, think again. UVA rays can penetrate through windows, exposing your skin while you're working from home, driving or sitting near natural light. Some studies also suggest that prolonged exposure to certain indoor light sources and light from digital devices can contribute to pigmentation and signs of ageing.

@youbyelina Why SPF is just as important in the winter months ❄️🥶 I’ve noticed many people stopping their SPF use over winter so PLEASE watch this if that’s you! #spf #skincaretips #skintok #antiaging #hyperpigmentation ♬ original sound - Pharmacist Elina

Your lips can't produce their own moisture

Because your lips lack oil (sebaceous) glands, they cannot moisturise themselves or retain hydration naturally. Unlike the rest of your skin, they rely on external moisture and a protective barrier to prevent severe dryness and chapping. While lip balm can help lock in moisture, staying hydrated and having a lipcare routine is equally important.
