Serums

Serum is the most functional product in the entire skincare routine: high concentration of specific active ingredients, texture that quickly penetrates deep layers, targeted action on a precise problem. It is not a universal product; each serum is created to do one thing, and do it well. The secret is to choose the right one for your skin's actual needs, not to chase the trending one.

In the catalog, serums are organized by their main active ingredient. Vitamin C for radiance, antioxidant protection, and spot reduction. Niacinamide for sebum regulation, tone uniformity, and pore visibility. Retinol for accelerated cellular renewal and wrinkle reduction. Peptides and growth factors for structural anti-aging action. Centella Asiatica and Heartleaf for soothing and barrier support. Hyaluronic acid and beta-glucan for deep hydration. Tranexamic acid for spots and hyperpigmentation.

K-Beauty has brought a significant innovation: the possibility of layering multiple light serums instead of a single thick serum, from the lightest to the densest, each with a main active ingredient, without mutual interference.

In Korean skincare you will often find the term Ampoule .

Although similar to serums, ampoules are even more concentrated and designed for intensive treatment cycles.

While the serum is a daily ally for maintaining balance, the ampoule steps in when the skin is particularly stressed, dull or marked, offering a "jolt" of essential nutrients in just a few drops.

To choose the right serum, learn about the most popular active ingredients on Auryn Skin:

  • Niacinamide: Perfect for minimizing pores and even out skin tone.
  • Vitamin C: The ultimate antioxidant for brightening and lightening blemishes.
  • Hyaluronic Acid: For plump and deeply hydrated skin.
  • Snail Slime and Peptides: To stimulate collagen and combat the signs of aging.

The serum should be applied after the Essence (or after the Toner, if you prefer a more streamlined routine) and always before the moisturizer .

Thanks to its fluid texture, it penetrates quickly.

2-3 drops are enough: dab with your fingertips from the center of the face outwards, focusing on the areas that need attention most (such as blemishes or dry patches).

The answer is yes, but be mindful. Layering is common in Korea, but we recommend not using more than two different serums in the same session.

For example, you can use a hydrating serum as a base and a highlighter on top.

Be careful with active ingredients, though: avoid mixing strong exfoliating acids and pure Vitamin C in the same routine to avoid irritating your skin.

This is a common mistake. Serums are formulated to deliver active ingredients deep into the skin, but they don't have the ability to "lock in" moisture. Without a final moisturizer , the serum's active ingredients could evaporate, making the treatment less effective.

Consider the serum as nourishment and the cream as protection.
