When it comes to getting and keeping healthier, younger-looking skin, everyone needs to use products that contain three types of ingredients: antioxidants, skin-restoring ingredients and skin-replenishing ingredients. Along with daily sun protection, each gives skin what it needs to visibly improve in numerous ways— but what do we mean by “skin replenishing”? Good question!
What Are Skin-Replenishing Ingredients?
Skin-replenishing ingredients are skincare ingredients that help enrich skin's surface, drenching it with revitalising hydration and keeping it there. They’re sometimes referred to as “skin-identical ingredients” because the best ones are also found in abundance in skin that’s young and not yet damaged by unprotected sun exposure.
How Skin-Replenishing Ingredients Work
Think of skin-replenishing ingredients as the “mortar” to the “bricks” of skin’s surface. Age, certain skin conditions, sensitive skin, and environmental assault cause the mortar—skin’s natural supply of replenishing and repairing ingredients—to progressively weaken, eventually becoming depleted.
When skin’s surface is weakened, it becomes much more vulnerable to external damage. This shows up as dryness, dehydration, redness, increased sensitivity, and an inability to hold on to vital moisture. Skin becomes dull, dry, flaky—older-looking.
Applying products rich in skin-replenishing ingredients helps keep skin looking and feeling soft, smooth, and supple—especially skin that's persistently dry, tight, and uncomfortable.
Daily application of skin-replenishing ingredients in products like your toner, face moisturiser, serum, eye cream, and sunscreen keeps skin safeguarded from environmental factors that lead to moisture loss and dehydration. These ingredients help skin appear younger, more vibrant, and, you guessed it, replenished!
Our Favourite Skin-Replenishing Ingredients
There are numerous skin-replenishing ingredients to consider, some of which are naturally present in skin, including hyaluronic acid, ceramides, sodium PCA, glycerin, glycerol, cholesterol, and phospholipids. Others include omega fatty acids, sodium hyaluronate, amino acids, and phytosphingosine.
You’ll find these ingredients (along with antioxidants and skin-restoring ingredients) in Paula’s Choice Skincare toners, such as RESIST Advanced Replenishing Toner, serums, such as RESIST Omega + Complex, moisturisers such as RESIST Intensive Repair Cream, and boosters such as Hyaluronic Acid Booster. In short, we’re devoted to using skin-replenishing ingredients in as many leave-on products as possible because research is clear how vital they are for all skin types, all ages!
