Serums, Ampoules, Emulsions and Essences: What’s the Difference?
From BB creams to sheet masks, we're obsessed with all things Korean beauty. While some K-beauty-inspired products are pretty straightforward (i.e. those just mentioned), others can be confusing at first. Because essences, ampoules and emulsions, all seem similar, you might not know which to use when, or if you even need all three in your routine at all. And what’s the difference between those products and serums? Don’t worry — we have you covered. Below, we’re breaking down what exactly what these formulas are, how they benefit your skin and how to use them.
What Is a Serum?
Serums are concentrated formulas with a silky texture that typically address a specific skin concern and are applied before moisturizer. Here are three to try:
If you have anti-aging or acne concerns, a retinol serum belongs in your routine. Try this drugstore formula that contains 0.3% of pure retinol for optimal results. Because the ingredient is so potent, start by using it once a week with moisturizer to avoid any irritation or dryness.
Another great anti-aging option is this serum that contains hydrating and plumping hyaluronic acid and antioxidant-rich iris extract.
If you’re more of a less-is-more kind of skin-care consumer, we recommend this three-in-one product. It serves as a serum, moisturizer and sunscreen and contains brightening ingredients to improve dull, uneven skin.
What Is an Emulsion?
Lighter than a cream yet thicker — and less concentrated — than a serum, an emulsion is like a lightweight facial lotion. Emulsions are the perfect product for oily or combination skin types who don’t need a thick moisturizer. If you have dry skin, an emulsion can be used after serum and before moisturizer for an extra layer of hydration. Here are three to try:
Formulated with niacinamide, a tripeptide complex and glycerin, this daily emulsion helps hydrate skin and target signs of premature aging.
Perfect for acne-prone skin, this K-beauty emulsion soothes inflamed breakouts and hydrates skin without clogging pores or making skin feel greasy.
This soothing, oil-free emulsion has a lightweight mattifying texture and was formulated with sensitive skin in mind.
What Is an Essence?
Essences are considered to be the heart of the Korean skin-care routine and are meant to provide a layer of hydration and soften the skin. Apply one after cleansing and toning, but before an emulsion, serum and moisturizer. Here are three to try:
This essence is formulated with micro-exfoliating lipo-hydroxy-acid (LHA) and hyaluronic acid and promotes a brighter, hydrated and more youthful-looking complexion.
A K-beauty fave, this essence is made up of 93% fermented ingredients to help you achieve glowing skin.
With antioxidant-rich ingredients like black chokeberry and ellagic acid, this essence goes a step beyond your classic essence formula by helping to brighten and even out skin tone and texture.
What Is an Ampoule?
Ampoules are like serums, but they typically have a high concentration of one or several active ingredients. Depending on the formula, they can be used every day in place of a serum or as part of a several-day treatment. Here are three to try:
This formula contains 10% vitamin C, hyaluronic acid, phyto-peptides and mineral water to help soften, smooth and brighten the skin.
If your skin is in need of hydration, this week-long treatment will become your new favorite ritual. Apply one every day for seven days to reveal a visibly plumped and hydrated complexion and to minimize the appearance of wrinkles.
This unique formula contains two phases: An oil phase to moisturize skin and an essence phase that helps target signs of aging. Use it every day in place of a serum.
How to Incorporate Serums, Ampoules, Emulsions and Essences into Your Skin-Care Routine
The general rule of thumb is that skin-care products should be applied from thinnest consistency to thickest. Of the four types of products mentioned here, essences should be applied first after cleanser and toner. Next, apply your serum or ampoule. Lastly, apply an emulsion before or in the place of moisturizer. You also don’t need to apply all of these products every day. How often you apply depends on your skin type and needs.
