The Beginner’s Guide to Moisturizing: Everything You Need to Know to Start Your Skincare Journey
Skin Deep
If you’ve ever stood in the skincare aisle feeling completely lost, this one’s for you.
Let’s be real, skincare can feel overwhelming. There are serums, essences, toners, oils, creams, and gels, each one promising to transform your skin in 30 days or less. It’s a lot.
But here’s what I want you to know before you spend a single dollar on any of it: the most important thing you can do for your skin isn’t a $100 serum or a 10-step routine. It’s something far simpler.
It’s moisturizing.
Done consistently, every single day, a good moisturizer is the foundation on which everything else is built. And once you understand why, it starts to make sense.
First, Let’s Talk About Your Skin Barrier
Your skin isn’t just the surface you see in the mirror. It’s a living organ, and its outermost layer, called the skin barrier, does two critical jobs: it keeps moisture in and irritants out.
Think of it like a brick wall. The skin cells are the bricks, and the lipids and fats between them are the mortar holding everything together. When that wall is intact and healthy, your skin stays hydrated, resilient, and calm.
But when the barrier gets damaged through harsh cleansers, cold weather, over-exfoliating, or just the natural aging process, water starts to escape faster than it should. Dermatologists call this transepidermal water loss, and it’s the root cause of dry, flaky, tight, or dull-looking skin.
Moisturizing is how you repair and reinforce that wall. It’s not a cosmetic step. It’s maintenance.
What Does a Moisturizer Actually Do?
Not all moisturizers work the same way. The best ones contain a combination of three types of ingredients, each doing a different job:
Humectants are the water magnets. They draw moisture from the air and from deeper layers of your skin up to the surface. Hyaluronic acid and glycerin are the most common examples you’ll see them in almost every moisturizer worth buying.
Emollients are the smoothers. They fill in the tiny gaps between skin cells, giving skin that soft, silky texture. Think squalane, ceramides, jojoba oil, and shea butter.
Occlusives are the sealers. They sit on top of the skin and create a physical barrier to stop moisture from evaporating. Petroleum jelly is the most effective occlusive there is, humble, cheap, and extremely effective.
A good moisturizer will ideally combine all three. That’s how you get skin that’s not just temporarily plump, but genuinely healthy over time.
Which Moisturizer Is Right for You?
The wrong moisturizer, even a good one, won’t work well for you if it doesn’t suit your skin type.
Here’s a quick breakdown:
Dry skin tends to feel tight, rough, or flaky after cleansing. You need a richer, creamier formula that delivers both hydration and a strong occlusive seal. Look for ceramides, shea butter, and squalane. Avoid anything with a high alcohol content, which will only make dryness worse.
Examples: Embryolisse Lait Creme, Cocokind Resurrection Polypeptide Cream,
Oily skin can feel greasy by midday and is often prone to breakouts. Here’s the thing, though: oily skin still needs moisture. When oily skin is stripped through harsh cleansers, it often compensates by producing more oil. The key is finding a lightweight, water-based gel or fluid that hydrates without clogging pores. Look for the word non-comedogenic on the label, and reach for ingredients like niacinamide and hyaluronic acid.
Examples: Netrogena HydroBoost, Cocokind Electrolyte Water Cream
Combination skin is exactly what it sounds like: oilier in the T-zone (forehead, nose, chin) and drier on the cheeks. A medium-weight moisturizer often does the job, or some people prefer using two different products on different areas of the face.
Examples: CeraVe PM Facial Moisturizing Lotion, Belif Aqua Bomb
Sensitive skin reacts easily to products, weather, stress, you name it. Keep it simple. Look for fragrance-free, minimal-ingredient formulas with calming ingredients like ceramides, oat extract, or centella asiatica. Fragrance, even “natural” fragrance from essential oils, is one of the most common causes of skin irritation, so avoiding it is a good rule of thumb when you’re starting.
Examples: Avène Tolerance Control Cream, Embryolisse Lait Crème Sensitive Moisturizer
When Should You Moisturize?
Twice a day: morning and evening. Every day. That’s the short answer.
The slightly longer answer: the best time to apply moisturizer is right after cleansing, while your skin is still slightly damp. Damp skin absorbs ingredients more effectively, and the moisture that’s already there gets locked in rather than evaporating. Pat your skin dry (don’t rub), and apply your moisturizer within about 60 seconds of cleansing.
In the morning, a lighter moisturizer works best because it layers well under sunscreen, and yes, sunscreen is non-negotiable, even in winter, even when it’s overcast. It goes on after your moisturizer, as the last step before makeup.
In the evening, your skin is in repair mode. Cell turnover speeds up overnight, and your skin is more receptive to nourishing ingredients. This is the time to use a richer formula. If your skin is very dry, you can even try slugging, applying a thin layer of petroleum jelly as the very last step to seal everything in while you sleep. It sounds strange, but it works.
The Bottom Line
Healthy skin isn’t about having the most elaborate routine or the most expensive products. It’s about consistency, understanding what your skin actually needs, and giving it that every day.
Moisturizing is where most beginners see the fastest, most noticeable improvement: less tightness, smoother texture, fewer dry patches, and over time, a more even and resilient complexion.
Start simple. Stay consistent. And trust the process your skin barrier will thank you for it.
