REJURAN

REJURAN is a South Korean skincare brand with a dermocosmetic focus for those seeking hydration and targeted care for radiance, skin texture, and visible signs of aging. The brand is primarily known for c-PDRN®, an ingredient technology based on purified DNA fragments from salmon that is combined with, among other things, niacinamide, humectants, and barrier-supporting ingredients.

What is REJURAN?

REJURAN Cosmetics is a Korean skincare brand developed by PharmaResearch, a South Korean biopharmaceutical company headquartered in Gangneung. The company works with pharmaceuticals, medical devices, dietary supplements, and cosmetics. REJURAN's at-home skincare products are cosmetic products that are applied to the skin.

The brand's range includes, among other things, ampoules, serums, toners, emulsions, face creams, eye creams, cleansers, face masks, and sunscreen. The main focus is on hydration, the skin barrier, radiance, elasticity, and a more even skin texture. REJURAN is therefore particularly relevant for those interested in ingredient-based Korean skincare for dehydrated, dull, or mature skin.

What is REJURAN known for?

REJURAN is primarily known for c-PDRN® and PharmaResearch's own DNA Optimizing Technology, usually abbreviated as DOT. According to PharmaResearch, the company manages the entire process for its PDRN, from extraction and purification to the finished ingredient and product. In the products' ingredient lists, c-PDRN® is usually listed as Hydrolyzed DNA.

What sets the brand apart is the combination of this salmon-based DNA ingredient with established cosmetic ingredients such as niacinamide, glycerin, sodium hyaluronate, ceramide NP, squalane, panthenol, and allantoin. The formulations vary between different products and markets. REJURAN should therefore not generally be described as fragrance-free, alcohol-free, silicone-free, or vegan without first checking the specific ingredient list.

Key ingredients in REJURAN's products

c-PDRN® and Hydrolyzed DNA

PDRN stands for polydeoxyribonucleotide and consists of DNA fragments. REJURAN's c-PDRN® comes from salmon and appears as Hydrolyzed DNA in several official ingredient lists. In cosmetic products, Hydrolyzed DNA has a skin-conditioning function, which means the ingredient is used to help keep the skin in good condition. You can explore more products with PDRN in skincare at Koreanbeauty.

Skincare products with PDRN that are applied to the skin should not be equated with injectable treatments. How a cosmetic product works is affected by the entire formulation, the concentration, and how regularly it is used.

Niacinamide

Niacinamide is a form of vitamin B3 found in, among other things, Turnover Ampoule, Dual Effect Ampoule, Triple Radiance Ampoule and Turnover Mask. The ingredient is used to support the skin barrier and can contribute to a more even skin tone, better moisture balance, and less visible pores. In REJURAN's formulations, it is often combined with PDRN and hydrating ingredients.

Glycerin, hyaluronic acid, and other humectants

Glycerin and sodium hyaluronate, a form of hyaluronic acid, help bind water and prevent the skin from feeling tight. Betaine, trehalose, and butylene glycol also appear in parts of the range. The combination makes several of the products relevant for dehydrated skin and for a routine where the goal is softer, plumper, and more hydrated-feeling skin.

Ceramide NP, squalane, and soothing ingredients

Ceramide NP and squalane are used in selected products to complement the skin's lipids and reduce the feeling of dryness. Panthenol, allantoin, centella asiatica, and bisabolol also appear in parts of the range and are used for their caring and soothing cosmetic properties.

Popular products from REJURAN

The products below are among those that REJURAN highlights clearly in its official international range.

REJURAN Turnover Ampoule

Turnover Ampoule is one of REJURAN's most prominent products and holds a central place in the brand's range. It is a concentrated ampoule with Hydrolyzed DNA, niacinamide, sodium hyaluronate, aloe vera, licorice root, and arbutin.

The formula is developed for skin lacking moisture and radiance or that feels uneven in tone and texture. The product has a light serum-like consistency and is used after cleansing and toner but before face cream and sunscreen.

REJURAN Dual Effect Ampoule

Dual Effect Ampoule is a PDRN ampoule focused on elasticity, the skin barrier, fine lines, and long-lasting hydration. The product contains 5,000 ppm c-PDRN® together with ceramide NP, squalane, trehalose, niacinamide, and sodium hyaluronate.

This combination makes the product especially relevant for dry, dehydrated, or mature skin. It may also suit those who want to combine hydration with care for a more resilient skin barrier and a softer skin texture.

REJURAN Nutritive Cream

Nutritive Cream is a rich and nourishing face cream developed for dry skin and skin that needs more emollient care. The formula contains Hydrolyzed DNA, glycerin, sodium hyaluronate, squalane, shea butter, as well as oils from jojoba, pomegranate, argan, rosehip, and borage.

The cream is used as the final moisturizing step after serum or ampoule, morning and evening. The rich composition is best suited to dry and mature skin or as a night cream when the skin needs more moisture and lipids. The product contains fragrance and should therefore be assessed individually for sensitive skin.

REJURAN Turnover Mask

Turnover Mask is an essence-soaked Sheet mask with Hydrolyzed DNA, niacinamide, glycerin, panthenol, allantoin, centella asiatica, aloe vera, and several types of ceramides. The mask is developed for intensive hydration and a calmer, softer, and more recovered skin feel.

The mask is used in the evening after cleansing and toner. Leave it on for about 10 to 20 minutes, remove it, and gently pat in the remaining essence. The formula contains fragrance and several plant extracts, which is important to know for sensitive or reactive skin.

More products in REJURAN's range

The brand's range also includes Triple Radiance Ampoule, RE-Balancing Toner, Intensive Eye Cream, cleansing products, emulsions, and sunscreen. This means that REJURAN can be used in several parts of the routine, from toner and serums and ampoules to face masks, face cream, and daily sunscreen.

Benefits of REJURAN

• Developed by the South Korean company PharmaResearch.
• Clear focus on salmon-based c-PDRN® and Hydrolyzed DNA.
• Combines PDRN with well-known humectant, emollient, and barrier-supporting ingredients.
• Offers several product formats for different parts of the skincare routine.

REJURAN compared with other brands

REJURAN differs from many other PDRN brands through its connection to PharmaResearch and the company's own process for extracting and purifying PDRN. The brand uses salmon-based PDRN, unlike brands that use plant-based PDRN alternatives.

Another important difference is that REJURAN Cosmetics is skincare for topical use. The products are not the same as professional REJURAN treatments or injectable skin boosters. Results and research from injectable treatments therefore cannot automatically be transferred to a serum, a cream, or a Sheet mask.

How do you use products from REJURAN?

1. Cleansing: Remove makeup, sunscreen, and impurities with a cleanser adapted to your skin type.
2. Toner: Apply toner with your hands or a cotton pad to cleansed skin.
3. Ampoule or serum: Apply a thin layer and let it absorb. For Turnover Ampoule and Dual Effect Ampoule, the brand states three to five drops once or twice a day.
4. Sheet mask: Use after toner but before face cream when the skin needs extra hydration.
5. Eye cream: Gently pat the product around the eye area according to the instructions on the packaging.
6. Face cream: Finish with a cream that helps preserve moisture.
7. Sunscreen: Use sunscreen as the last step in the morning.

You do not need to use a complete routine from the same brand. An ampoule from REJURAN can, for example, be combined with a gentle cleanser, a hydrating toner, a face cream from another brand, and sunscreen during the day.

Which product from REJURAN suits me?

For dry or dehydrated skin: Look for formulations that combine Hydrolyzed DNA with glycerin, sodium hyaluronate, trehalose, squalane, or ceramide NP. Dual Effect Ampoule provides a lighter hydrating step, while Nutritive Cream offers a richer and more emollient texture.

For skin with fine lines and reduced elasticity: Turnover Ampoule and Dual Effect Ampoule are developed for care targeting firmness and skin texture. They can be combined with a moisturizing cream and daily sunscreen. Also see Koreanbeauty's range for mature skin.

For uneven skin tone or lack of radiance: Choose a product with niacinamide and complementary ingredients such as licorice root, arbutin, or mulberry extract. Turnover Ampoule and Triple Radiance Ampoule are official examples with this type of ingredient profile.

For normal, oily, or combination skin: A lightweight ampoule may be easier to combine with other products than a rich cream. Turnover Ampoule and Dual Effect Ampoule have lighter textures, while Nutritive Cream is primarily developed for skin that needs more oils and emollient ingredients.

For sensitive skin: REJURAN should not automatically be considered suitable for all sensitive skin. Some formulations contain fragrance, alcohol, essential oils, or multiple plant extracts. Always check the ingredient list, introduce one product at a time, and preferably test on a smaller area of skin. You can also compare with other skincare for sensitive skin.
