The brand's name is a fusion of “Island”, “Natural”, and “Tree”, reflecting the philosophy of a pure, untouched island filled with natural ingredients and vitality. This meaning permeates everything Isntree does – from their ingredient choices to their values.

Many of the products are also vegan (completely free from animal ingredients), although the brand is not 100% vegan across all products. All formulas undergo strict quality controls and dermatological testing before launch – no compromises on safety here. Isntree is proudly ISO-certified and follows CGMP standards in production, meaning each product meets high standards of purity and effectiveness.

What makes Isntree unique?

Natural + High-Tech - Isntree combines the power of nature with modern skincare technology. Their signature ingredients include nutrient-rich birch sap, soothing Centella Asiatica (cica), antioxidant-packed green tea, and radiance-boosting niacinamide. These natural ingredients hydrate, soothe, and protect the skin. For example, several of their bestsellers contain a high percentage of green tea extract from Jeju Island, rich in vitamins (including Vitamin C) and polyphenols that protect the skin from environmental damage. Isntree retains the full nutritional value of the ingredients – Green Tea Fresh Toner has a naturally light brown color because it is loaded with 80% real green tea without unnecessary additives.

Moisture, Moisture, Moisture - If there's something Isntree is known for, it's hydration. Many of The products contain multiple types of hyaluronic acid in different molecular sizes to provide maximum deep hydration. Their innovative Multi-Hyaluron Technology with up to 8–10 types of hyaluronic acid draws in and binds moisture in all skin layers. The result? Plumped, soft skin with improved elasticity and a healthy glow. The moisture booster Hyaluronic Acid Water Essence combines a full eight types of hyaluronic acid – from large molecules that hydrate the surface to tiny ones that penetrate deeply – all to chase away any signs of dryness. Together with ingredients like betaine and panthenol, it helps the skin retain moisture and strengthen its own barrier function.

Gentle for all skin types - Isntree creates skincare for sensitive skin – and for dry, combination, and oily skin as well. Thanks to skipping irritating substances, the products are also suitable for reactive skin that easily gets redness or breakouts. Everything is formulated to be gentle yet effective: even if you have acne-prone or eczema-prone skin, you can benefit from their products without worry. For example, almost the entire range is fragrance-free and alcohol-free, minimizing the risk of irritation. Additionally, Isntree often adds soothing extracts like allantoin, beta-glucan, and licorice root that calm redness and stress in the skin. Do you have problems with oily skin and pores? Their Green Tea Fresh line contains an Anti-Sebum complex that balances sebum production and minimizes pore visibility. Are you instead dry and tight in the skin? Their hyaluron products provide intense hydration and lock in moisture to keep the skin barrier strong. Isntree truly lives up to its promise to grow with consumers and give us what our skin needs.

Quality and innovation - Another factor that makes Isntree unique is how they develop their products. Every formula is born from customer feedback – they listen to what we skincare lovers are asking for and refine the recipes until everything is perfect. They use patented complexes (e.g., their plant-based Phyto-Oligo, a combination of mallow root and aloe, for extra moisture), and ensure the ingredients work together optimally. Everything is tested carefully in several rounds to ensure effectiveness without compromising gentleness. Dermatologically tested skincare is not just a slogan – it shows in the results on the skin. Many users testify how Isntree has improved their skin texture, reduced redness, and given a healthier skin tone over time. And despite this high quality, Isntree manages to keep their products surprisingly affordable – you don't have to empty your wallet to indulge in high-class Korean skincare anymore.

Skincare routine with Isntree

A Korean skincare routine is about layering products in the correct order – often called the layering method – to maximize the effect. Here is a suggestion for a complete routine with Isntree and how to use each step.

Cleansing

Start with a gentle facial cleanser that gently removes dirt, sunscreen, and impurities without disrupting the skin's barrier. Example: Isntree Sensitive Balancing Cleansing Foam is a foaming cleanser that balances the skin and does not leave it tight. The purpose of step 1 is to get a clean base so that subsequent products can penetrate the skin properly.

Toner

Directly after cleansing, apply a toner to moisturize and balance the pH level. The toner acts as the first layer of moisture and helps prepare the skin for serum. Tips: In the morning, you can choose a light, sebum-regulating toner like Green Tea Fresh Toner to keep shine under control, and in the evening, perhaps an extra moisturizing toner like Hyaluronic Acid Toner Plus if your skin feels dry. The toner also soothes any irritations and begins the process of strengthening the skin barrier (thanks to ingredients like centella and hyaluronic acid).

Serum/Essence

After toner comes serum – this is where you add concentrated ingredients that work on specific needs. The layering method suggests that thinner serums and essences go first. Moisturizing serums like Isntree's hyaluronic essence plump the skin and deeply hydrate (perfect for fine lines and dehydrated skin). If you instead want to work on dull tone and pores, a niacinamide serum or vitamin C-based serum can be used to add radiance and even out the skin tone. The purpose of step 3 is to give the skin a high dose of active ingredients – such as antioxidant-rich or barrier-strengthening – that target what you want to improve.

Moisturizer

Then you seal everything with a moisturizer. Choose the texture according to your skin type: Aqua Gel Cream if you want a light gel that locks in moisture without feeling greasy, or Hyaluronic Acid Moist Cream if you need a bit richer hydration that lasts all day. The cream softens the skin, further strengthens the skin barrier, and ensures that all moisture and nutrients from previous steps remain in the skin. After this step, the skin feels supple, balanced, and thoroughly “encapsulated” with nourishment.

Sunscreen (daytime)

In the morning, you finish the routine with sunscreen – a must in Korean skincare. Hyaluronic Acid Watery Sun Gel is an excellent choice that not only protects against UV rays but also provides extra moisture and glow during the day. The purpose is to preserve the results of your routine and protect the skin from the harmful effects of the sun (which can damage both collagen and radiance). In the evening, you can of course skip SPF.

By following this order – from the thinnest product to the thickest – you ensure that each layer is absorbed optimally and that your skin gets the maximum benefit from all the wonderful ingredients. Isntree's products are designed to work together in such a skincare routine, so you can easily build a comprehensive solution for your skin with this brand!
