The truth is, it’s not about choosing one over the other; they serve different but complementary purposes. Both go hand in hand; both have different uses and benefits. In this blog, we will dive deep into sunscreen creams vs serums, serum benefits, how and when to use serums, sunscreen benefits, and how and when to use sunscreen.

Sunscreen vs Serum: Uses, Tips, and Benefits

What is Sunscreen and How Does it Work?

Sunscreen is an essential skincare product that helps keep the harmful UV rays of the sun from affecting the skin. It creates a protective layer on the surface of the skin against harmful and damaging UV rays. It does this either by absorbing or reflecting the UV rays. UVA and UVB rays penetrate the skin and lead to many skin issues, such as sunburn, premature aging, pigmentation, dark spots, excessive dryness, and, in some cases, skin cancer. A sunscreen helps keep these harmful rays away from the skin.

 

Types of Sunscreen

There are two types of active ingredients in any sunscreen. Also known as UV filters, these active ingredients are physical barriers (mineral sunscreens) and chemical barriers (chemical sunscreens). Based on the active ingredient present in the sunscreen, it's categorized into mineral or chemical sunscreen.

 

Mineral Sunscreens

Also known as physical sunscreens, these sit on the outermost layer of the skin and act as a physical barrier, diverting the harmful rays. Mineral sunscreens benefit the skin by blocking the UV rays of the sun at the surface level and provide optimal protection against UVA and UVB rays. The active ingredient present in mineral sunscreens is titanium dioxide or zinc oxide or, many times, the combination of both.

 

Chemical Sunscreens

Chemical sunscreens go in the deeper layers of the skin, unlike physical or mineral sunscreens. Chemical sunscreens work by absorbing the UV rays of the sun and converting them into heat before releasing them from the skin. Active ingredients present in the chemical sunscreens are oxybenzone, octinoxate, octisalate, homosalate, avobenzone, or combinations of these. These sunscreens take approximately 20-25 minutes to activate and exert their power, and it is advised to wait for 30 minutes after application and before stepping out in the sun.

What is Serum and How Does it Function in Skincare?

Serums are light skincare products packed with concentrated ingredients made to reach deeper skin layers. They help deal with issues like acne, dull skin, dark spots, or fine lines. Ingredients like vitamin C, hyaluronic acid, or salicylic acid in serums can go deep because of their tiny molecules, so the skin absorbs them fast. They support the skin by repairing, protecting, and giving it the care it needs.

 

How do serums function?

●     Specific treatment: It is dedicated to some skin issues, such as acne, dry spots, or dark spots.

●     Good absorption: They are absorbed deeper into the skin due to small molecules and concentrated active ingredients.

 


Types of Serums

Many kinds of serums cater to different skin needs:

●     Hydrating serums use hyaluronic acid to combat dryness.

●     Brightening serums with vitamin C help lighten dark spots and bring back glow.

●     Anti-aging serums made with retinol and peptides work to reduce fine lines and give the skin a refreshed look.

●     The oily skin is controlled using oil-control serums to regulate the sebum level.

●     Several other acne-fighting serums contain salicylic acid or niacinamide to unclog the pores and minimize the breakouts.

Tips for Choosing the Right Product for Your Skin Type

It is very important to choose the right product for your skin based on your lifestyle and skin type. Here are some tips to help you choose the best for your skin:

 

Sunscreen Tips

●     Broad Spectrum: Ensure to buy a broad-spectrum sunscreen to protect your skin from both UVA and UVB rays.

●     Skin Types and Concerns: Choose the sunscreen based on your skin type and skin concerns. Choose hydrating and cream-based sunscreen for dry skin, oil-free sunscreen for oily skin, and mineral sunscreens for sensitive skin.

●     Water Resistant: Choose a water-resistant sunscreen if you go swimming.

 

Serum Tips

Benefits of Using Sunscreen and Serum Together

Using serum and sunscreen together assists in achieving a brighter, even-toned, dark-spot-free, hydrated, and aging-free skin, and also prevents the onset of aging changes such as wrinkles and sagging.

Conclusion

Serums and sunscreens go hand in hand; they are never to be used alone. Serums benefit by locking in moisture and penetrating deeper in the skin layers, whereas sunscreens benefit the skin by shielding it from all the harmful UV rays of the sun. While choosing the best serum and sunscreen for your skin, take into consideration your skin type and your lifestyle. Always do a patch test before applying to identify if it suits your skin.
