Which ingredients should be avoided if you have sensitive skin, and how can you find products that are well tolerated?

For sensitive skin, it's important to avoid ingredients that could cause irritation, redness or allergic reactions. Here are some ingredients that people with sensitive skin may want to avoid and tips on how to find products that are well tolerated:

Ingredients to avoid:

  1. Fragrances: Artificial fragrances can cause skin irritation. It is better to choose fragrance-free products.
  2. Alcohol: Alcohol can dry out and irritate the skin. Highly denatured alcohol in particular should be avoided.
  3. Sharp acids: Harsh acids such as glycolic acid or salicylic acid can cause skin irritation. Use these ingredients in low concentrations.
  4. Synthetic dyes: Artificial colorants can trigger allergic reactions. Natural dyes are often better tolerated.
  5. Sulfates: Sulphates such as sodium lauryl sulphate can dry out and irritate the skin. Look for sulphate-free cleansing products.

Tips for choosing compatible products:

  1. Short lists of ingredients: Products with shorter ingredient lists often have less potential for irritation.
  2. Hypoallergenic labeling: Look for products that are labeled hypoallergenic. Please note, however, that this labeling is not always a guarantee of compatibility.
  3. Gentle formulations: Look for products that are formulated as gentle, mild or for sensitive skin.
  4. Patch test: Carry out a patch test before using a new product. Apply a small amount to an inconspicuous area of your skin and observe whether irritation occurs.
  5. Dermatological recommendations: Consult a dermatologist or dermatologist for individual recommendations for your skin care.
  6. Online research: Read online reviews and experiences of people with similar skin problems to find products that are well tolerated by other sensitive skin types.
  7. Natural ingredients: Natural ingredients such as aloe vera, chamomile or oats can often be more suitable for sensitive skin.

It's important to be patient and find the right skincare routine through trial and error. Start with a simple routine and add products as needed to avoid reactions. If you notice severe or persistent skin irritation, be sure to consult a dermatologist.

What role do vitamin C and hyaluronic acid play in anti-ageing cosmetics?

Vitamin C and hyaluronic acid are two key ingredients in anti-ageing cosmetics, each playing a specific role in improving skin health and combating the signs of ageing. Here is an overview of their functions:

Vitamin C:

  1. Antioxidant effect: Vitamin C is a powerful antioxidant that can protect the skin from the damaging effects of free radicals. Free radicals can cause cell damage, which can lead to premature skin ageing.
  2. Collagen production: Vitamin C plays an important role in the synthesis of collagen, a protein responsible for the elasticity and firmness of the skin. As we age, natural collagen production decreases and vitamin C can help to support this process.
  3. Skin whitening: Vitamin C can help reduce pigmentation spots and uneven skin tone by regulating the production of melanin and improving the appearance of hyperpigmentation.
  4. Reduction of fine lines and wrinkles: By promoting collagen production and protecting against oxidative stress, vitamin C can help reduce the appearance of fine lines and wrinkles.

Hyaluronic acid:

  1. Moisture binding: Hyaluronic acid is a natural substance that can bind moisture very effectively. It can increase the skin's ability to bind water and make it appear plumper and more hydrated.
  2. Filling effect: As hyaluronic acid is able to bind water, it can temporarily reduce the appearance of fine lines and wrinkles by slightly plumping up the tissue under the skin.
  3. Support of the skin barrier: Hyaluronic acid can help to strengthen the skin barrier, which in turn can protect the skin from environmental stresses.
  4. Smooth texture: Products with hyaluronic acid can improve the feel of the skin and make it softer and smoother.

Combinations of vitamin C and hyaluronic acid are often used in anti-ageing products to achieve synergistic benefits. While vitamin C promotes collagen production and protection against free radicals, hyaluronic acid helps to moisturize the skin and give it a smoother appearance. However, it is important to note that the effectiveness of products depends heavily on the concentration and quality of these ingredients. When choosing anti-ageing products, it is advisable to look for high-quality formulations and, if necessary, speak to a dermatologist to find the best products for your skin needs.

How do natural oils such as argan oil or jojoba oil influence the effectiveness of hair care products?

Natural oils such as argan oil and jojoba oil are often used in hair care products as they can provide various benefits for the hair. Here's how they can influence the effectiveness of hair care products:

  1. Moisturizing: Argan oil and jojoba oil are rich in moisturizing properties. They can be used in hair care products such as shampoos, conditioners and hair masks to lock moisture into the hair, combat dryness and make the hair more supple.
  2. Smoothing and untangling: These oils can help to smooth the hair and make it easier to comb. They can be used in leave-in conditioners or hair serums to reduce frizz and detangle the hair.
  3. Protection from heat styling: Argan oil and jojoba oil can act as natural heat protectants. They form a protective layer around the hair, protecting it from the damaging effects of heat from blow-drying, straightening or curling irons.
  4. Gloss and shine: The use of oils such as argan oil and jojoba oil can give the hair a healthy shine and make it more visually appealing.
  5. Scalp health: These oils can also help to support scalp health by reducing dryness and irritation.
  6. Treatment of damaged hair: Argan oil and jojoba oil can be used to revitalize and repair damaged hair. They can be used in hair masks or deep conditioning products.
  7. Prolongation of color brilliance: In hair products for colored hair, these oils can help to make the color last longer and protect the hair from fading.

It is important to note that the amount and type of oils used must be considered, as well as the individual needs of the hair. People with fine hair may prefer lighter oils, while those with thick or curly hair may benefit from richer oils. The right dosage is also important, as too much oil can weigh hair down and make it look greasy. Before using products with natural oils, I recommend checking the instructions on the packaging and asking a professional or hairdresser for advice if necessary.
