Skincare Ingredients 101: What Do Retinol, Hyaluronic Acid, and Vitamin C Really Do?
Your cheat sheet to understanding three of the most talked-about ingredients in skincare.
With so many product labels boasting powerhouse ingredients, it can be overwhelming to know what does what—and more importantly, which ones you actually need. At Beach House Day Spa, we believe that skincare should feel approachable and effective. So let’s break down three of the most buzzed-about ingredients in the skincare world: Retinol, Hyaluronic Acid, and Vitamin C.
Retinol: The Texture Refiner
What it does: Retinol is a form of Vitamin A that helps speed up cell turnover. It’s best known for its ability to smooth fine lines, fade dark spots, and improve skin texture.
Best for: Aging concerns, uneven texture, and breakouts
How to use it: Retinol is typically used at night (sunlight can reduce its effectiveness). Start slow—2–3 times per week—and always follow with SPF in the morning, as it can increase sun sensitivity.
Hyaluronic Acid: The Hydration Hero
What it does: Despite the word “acid,” this ingredient is ultra-gentle. Hyaluronic acid is a humectant that draws moisture into the skin, leaving it plump, dewy, and refreshed.
Best for: All skin types, especially dry or dehydrated skin
How to use it: Apply it to slightly damp skin, then seal it in with a moisturizer. It works beautifully both morning and night.
Vitamin C: The Brightness Booster
What it does: Vitamin C is a potent antioxidant that helps protect your skin from free radicals (like UV rays and pollution). It also brightens dull skin and helps fade dark spots.
Best for: Dullness, hyperpigmentation, and skin exposed to environmental stress
How to use it: Use it in the morning under SPF for maximum protection and glow.
