Ren Skincare Health Benefits

Ren Skincare is a brand that focuses on providing clean and effective skincare products using sustainably sourced and natural ingredients. Their mission is to offer products that deliver visible results without harming the skin or the environment. Ren Skincare is committed to using clean and eco-friendly packaging and aims to become a zero-waste brand.

Ren Skincare offers a range of products that target various skin concerns, including the Glow and Protect Serum and the Radiance Brightening Dark Circle Eye Cream. 

The Glow and Protect Serum is a lightweight serum that helps to protect the skin from environmental stressors while providing a radiant glow. It contains natural bio-actives like vitamin C, magnesium, and other fruits, which work together to even out the skin tone and reduces the appearance of fine lines and wrinkles. 

The Brightening Dark Circle Eye Cream is a moisturizing eye cream that helps to reduce the appearance of dark circles, puffiness, and fine lines around the eyes. It contains natural ingredients like hyaluronate, vitamin C, and elderberry extract, which work together to hydrate, brighten, and rejuvenate the delicate skin around the eyes.

3 Health Benefits of Glow and Protect Serum and Brightening Dark Circle Eye Cream

These REN products contain several ingredients that can benefit your skin.

1. Bright and Glowing Skin 

The Glow and Protect Serum contains Kakadu plums and Ascorbyl Tetraisopalmitate, which are rich in vitamin C. 

Kakadu plums contain the highest recorded natural amount of vitamin C of any food in the world. Vitamin C helps stimulate collagen synthesis and provides antioxidant protection against UV-induced photodamage. Vitamin C can also help to fade dark spots and hyperpigmentation by inhibiting melanin production.

The elderflower in the eye cream is also rich in antioxidants that protect against free radical damage, including damage caused by the sun. It also promotes blood circulation and contains high amounts of vitamins A, B, C, and E. These nutrients can help make the skin firmer, improve complexion, and even out skin tone. It also protects against UV radiation.

Elderflower has a particular benefit for those struggling with dark circles under the eyes, as it brightens the skin and reduces the appearance of dark circles. 

Ascorbyl Tetraisopalmitate, Magnesium Ascorbyl Phosphate, Punica Granatum Seed Oil, and Rosa Canina Fruit Oil also share the common benefit of being rich in vitamin C, a potent antioxidant that can help to brighten the skin, protect it from environmental stressors, and reduce the appearance of dark spots and hyperpigmentation. 

Punica Granatum Seed Oil can also improve the overall appearance of the skin. Rosa Canina Fruit Oil has anti-inflammatory properties that can calm and soothe the skin and improve its texture and tone. 

2. Smooth and Acne Free Skin

Kakadu plums have natural antibacterial, antioxidant, and anti-inflammatory properties, which are helpful in preventing acne and treating related skin concerns.

The serum and eye cream both contain Helianthus Annuus Seed Oil, which has Omega-6 (linoleic acid), which can help smoothen skin texture. Linoleic acid can help in cell development and treatment of skin disorders such as eczema, acne, and scarring.

When used topically, linoleic acid also has an anti-inflammatory effect and helps to maintain the skin’s natural barrier. Additionally, it protects the skin against bacteria and germs, making it beneficial for conditions such as acne.

The Glow and protect serum also contains Dragon Fruit. It is also a rich source of vitamin C and protects against free radicals. Adding dragon fruit into your daily diet can help reduce the appearance of fine lines and wrinkles by activating fibroblasts that produce new collagen, which keeps the skin firm and strong.

3. Healthier and Supple Skin

Sodium hyaluronate, which is present in both products, easily mixes with water because it is hydrophilic. It increases skin hydration by attracting moisture in skin cells, reducing dryness and flaking when applied topically.

Sodium hyaluronate, a low molecular weight HA, can provide a greater hydrating effect, keeping the skin youthful and supple.

Another substance found in the eye cream, glycogen, can improve the moisture levels of human skin. Glycogen increases the amount of ceramide in the epidermis, which is crucial for retaining moisture in the skin. This could make your skin look more supple and glowing. 

Both formulations also contain glycerin, a humectant that helps draw moisture into the skin, thus improving hydration and giving the skin a plump, healthy appearance.

How to Use

To use the Glow and Protect Serum, follow these steps:

  1. Cleanse your skin thoroughly using the Clean Jelly Oil Cleanser or Micro Polish Cleanser.
  2. After cleansing your skin, apply a small amount of the Glow and Protect Serum onto your hands and gently press it onto your face.
  3. Massage the serum into your skin in circular upward and outward motions until fully absorbed.
  4. Wear an SPF if you are using the serum as part of your morning routine.

  1. After cleansing your skin, carefully apply the Brightening Dark Circle Eye Cream to the eye contour area and gently massage until fully absorbed.
  2. Apply the Glow and Protect Serum as described above.
  3. Massage the Glow Daily Vitamin C Gel Cream onto your face and neck until absorbed as part of your morning routine.
  4. Follow with an SPF for daytime use or sleeping cream for nighttime use.

Side Effects 

It’s important to note that everyone’s skin is different, and some people may be more sensitive to specific ingredients than others. Here are some possible side effects of using REN products if used excessively:

Irritation and Redness:

  • Benzyl Alcohol: This is a type of alcohol that is commonly used as a preservative in cosmetics and skincare products. It can help to prevent the growth of bacteria and other microorganisms in the product. However, it can cause skin irritation, itching, and redness.
  • Citric Acid: This is an organic acid in many fruits, including lemons and limes. In skincare products, it is used as a pH adjuster and exfoliant. While it can effectively promote cell turnover and brighten the skin, it can also cause stinging, burning, and redness in some people, especially those with sensitive skin.
  • Sodium Hydroxide: Also known as lye, this is a highly alkaline substance that is used in many skincare products as a pH adjuster. It can help to neutralize acidic ingredients and promote a balanced pH in the skin. However, it can also cause skin irritation, burning, and redness in some people, especially if used in high concentrations. Prolonged or repeated skin contact may also cause dermatitis.

Skin irritation, rash, and allergy:

  • Limonene and Linalool: These are naturally occurring compounds found in the peels of citrus fruits. They are used as a fragrance in skincare products. While they are generally considered safe, they may cause skin irritation, rash, and allergy in some people.

Kakadu plum, dragon fruit, pomegranate, elderberry flower extract, and glycogen are generally considered safe for use on the skin. However, it’s always important to patch-test new products and ingredients before using them on a larger area of skin to make sure you don’t have an allergic reaction or sensitivity to any of the ingredients.

Pros and Cons

It’s important to note that individual experiences with skincare products can vary, and what works well for one person may not work well for another. It’s always a good idea to patch-test a new product on a small area of skin before applying it all over your face and to discontinue use if you experience any adverse reactions.
