Facial serums have been around the beauty scene for quite some time, proving they're the perfect companion when you decide to take your skincare to the next level.
If you're still hesitating about whether you really need to use facial serums, I understand. You may be unsure about what they are, what they do, what their benefits are, and how to choose the right one for you.
Many Western beauty products are derived from the incredible but lengthy Korean skincare rituals, which include facial serums and, more recently, essences. And with the busy lives we lead in this part of the world, the last thing we want to do is add another product to the three- or four-step routine that already seems like enough.
What are facial serums? How do they differ from other skincare products?
A little chemistry: Facial serums are solutions, mostly water-based, used as a means of application for various substances that are physiologically compatible with our bodies due to their formulation with defined characteristics such as pH and colligative properties (for example: osmotic pressure = solvent ratio & solute concentration).
They consist of low molecular weight solutions intended for topical use (in some cases without the emulsifiers and thickeners found in creams and lotions) that are rapidly absorbed and penetrate the different layers of the skin. They are concentrated in the distribution of active ingredients such as antioxidants, vitamins, peptides, Hyaluronic acid, and lightening agents that focus their treatment on one or more skin issues.
Facial serums have specific benefits that increase the likelihood of achieving the results you want without replacing other products you already use, such as moisturizers.
Do I really need a serum?
In general, serums are good for all skin types. Your choice will depend on the particular issue you want to address, such as acne or hyperpigmentation, or a skin concern you're trying to address, such as dehydration and fine lines or wrinkles.
How and when should you use serums in your current skincare routine?
After cleansing, after toner, but before moisturizer. Be careful not to make a common mistake: letting your face dry completely. Your skin will absorb the active ingredient better if it's damp. *This advice doesn't apply to retinoic acid alone. Then, you need to lock in a moisturizing barrier—a lotion or cream, whichever you prefer—to help retain that moisture all day.
The key to skincare cocktails, especially facial serums, is:
1. Knowing how to choose the right one for your needs.
2. Using it correctly.
3. Knowing which active ingredient blend is compatible with another.
So, if you decide to combine multiple serums…
Which ones don't work well together?
Copper peptides counteract topical vitamin C.
AHAs or alpha hydroxy acids (lactic acid, glycolic acid, mandelic acid) and retinoic acid should also not be mixed, as one degrades the other.
Glycolic acid, salicylic acid, and retinoic acid, applied at the same time, can cause a bigger problem than the one intended to solve. Used this way to treat acne, they can make it worse.
Incompatible ingredients can irritate the skin, cause breakouts, sensitivity, rashes, and contact or atopic dermatitis. Others become less effective when mixed and may even cancel out the ingredients altogether. So check the ingredient list on the label.
Also, follow these other tips.
1. Store them in a cool, dry place.
2. Depending on the serum and its ingredients, you can use them anywhere from six months to a year once opened. But vitamin C, for example, is known to lose its effectiveness and potency fairly quickly, while retinol can last up to nine months. Make sure to read the label to know how much to apply, how to store it, and when to discard it.
3. Apply consistently for at least two months so your skin reveals visible and lasting results.
4. Most serums can be used twice a day, morning and/or night.
5. But to get the most out of an ingredient, apply each one separately and divide them between your morning and night routine.
6. Use your antioxidant serum in the morning to increase the sunscreen's protection.
7. If they have a similar consistency, start with the lightest serum or the serum with the benefits most important to you first. Wait a minute or two before moving on to the next one.
You can also create your ideal serum blend in the palm of your hand to save time, like I do.
Take this opportunity to do a light facial massage for ten to fifteen seconds. Apply the serum to your face, applying gentle pressure with your hands, then to your eyes and surrounding areas, then moving to your mouth and neck. This relaxes your features and stimulates the skin's capillary system, which is key for supplying nutrients and oxygen to your face.
Maintain a basic routine with a normal skincare regimen that includes your cleanser, your chosen serum, and your moisturizer. Always be careful not to overuse one ingredient or several ingredients together, which could irritate your skin.
