Skincare Myths Part 1 | Sunscreen, Moisturizer, and Pores

The skincare world is filled with myths that can lead to confusion and ineffective routines. Today, we’re tackling three of the most common misconceptions—sunscreen on cloudy days, moisturizing oily skin, and whether pores open and close. Understanding the truth behind these myths can help you make better skincare choices and achieve healthier, more radiant skin.

Myth #1: You Don’t Need Sunscreen on Cloudy Days

The Truth: UV rays are present year-round, even on cloudy and rainy days. Up to 80% of UV radiation can penetrate clouds, exposing your skin to potential damage. This means that even if the sun isn’t visible, harmful rays still reach your skin, accelerating signs of aging and hyperpigmentation and increasing the risk of skin cancer.

Many people underestimate the cumulative effects of daily sun exposure. Even short periods outdoors without sunscreen can contribute to long-term skin damage. UVA rays, which penetrate deeper into the skin, are responsible for breaking down collagen and elastin, leading to wrinkles and sagging. This is why wearing sunscreen consistently, even when indoors near windows, is a crucial step in any anti-aging skincare routine.

Why Daily Sunscreen Matters:

• UVA rays contribute to premature aging and penetrate deeper into the skin.
• UVB rays cause sunburn and increase skin cancer risks.
• Sunscreen provides a protective barrier to prevent both types of damage.

What You Should Do:

• Apply a broad-spectrum SPF 30 or higher every morning, even if you’re staying indoors (UVA rays can pass through windows!).
• Reapply every two hours when outdoors.
• Use a sunscreen suited to your skin type—lightweight formulas for oily skin, hydrating options for dry skin, and tinted sunscreens for added coverage.

Myth #2: Oily Skin Doesn’t Need Moisturizer

The Truth: It may seem logical to skip moisturizer if you have oily skin, but it can worsen matters. When your skin lacks proper hydration, it compensates by producing even more oil, which can lead to clogged pores and breakouts.

Oily skin can still be dehydrated, lacking water rather than oil. Dehydration can make skin feel tight, flaky, or irritated despite appearing shiny. Without a proper moisture barrier, the skin becomes more vulnerable to environmental aggressors, leading to inflammation and an increased risk of breakouts. The right moisturizer helps to maintain skin health by providing hydration without making the skin feel greasy.

Why Hydration is Key for Oily Skin:

• Dehydration triggers excess sebum production, making skin appear shinier and more prone to acne.
• A well-formulated moisturizer helps maintain balance, preventing the skin from overcompensating with oil.
• Ingredients like hyaluronic acid, niacinamide, and lightweight gel-based formulas provide hydration without clogging pores.

What You Should Do:

• Choose an oil-free, non-comedogenic moisturizer.
• Look for hydrating ingredients like glycerin, aloe vera, or hyaluronic acid.
• Apply moisturizer morning and night to keep your skin balanced.

Myth #3: Pores Open and Close

The Truth: Pores don’t have muscles, which means they cannot physically open or close. The size of your pores is primarily determined by genetics, though factors like oil production and congestion can make them appear larger.

While pores don’t change size, skincare habits can influence their appearance. Pores clogged with dirt, oil, and dead skin cells may look more noticeable. Additionally, a loss of skin elasticity due to aging or sun damage can make pores appear larger over time. Keeping pores clear and protecting the skin’s collagen with proper skincare can help them look less prominent.

Why Pores Look Enlarged:

• Clogged pores stretch due to excess oil, dead skin, and debris buildup.
• Sun damage weakens collagen, making pores less firm and more noticeable.
• Dehydration can make pores appear more prominent.

What You Should Do:

• Use a gentle exfoliant like salicylic acid or enzymes to keep pores clean.
• Apply niacinamide to regulate oil production and improve skin texture.
• Always wear sunscreen to protect against collagen breakdown.

Understanding these common skincare myths can help you develop a routine that benefits your skin.
