Curated Skincare Developed By Science And Designed For Your Skin By Dermatologists

The Problem: As Dermatologists, we have observed an increase in skin issues like irritation and dermatitis caused by product overuse, layering, and mixing incompatible ingredients.

With the more is better mentality, people are using too many products with high concentrations of active ingredients, leading to ineffective combinations and the potential for irritation.

Skincare has become overly complicated, with numerous brands and clever marketing.

The Solution: The Skin Diary streamlines your routine by carefully selecting compounds that complement each other, making it both effective and easy to follow.

 

Just Like Your Body Craves Vitamins For Overall Health, Your Skin Also Needs Nourishment To Thrive

Even potent prescription-grade retinoic acid is a derivative of vitamin A. You might wonder, why is it only available through prescription? The answer lies in its incredible effectiveness.

Retinoids have been scientifically proven to transform your skins biology by boosting collagen production and enhancing the epidermis.

Compounds that bring about such significant changes cannot be marketed as mere cosmetics and if used improperly can cause severe irritation.

We believe in the science-backed approach to skincare, ensuring that your skin receives the nourishment it deserves to flourish and radiate vitality.

Active Ingredient

Retinoic Acid

Retinoic Acid, a derivative of vitamin A, that is commonly used in anti-ageing skincare. It is a powerful prescription grade ingredient that works by increasing cell turnover and stimulating collagen production, resulting in smoother, brighter, and more youthful-looking skin. Retinoids are particularly effective at reducing the appearance of fine lines, wrinkles, and age spots, as well as improving skin texture and tone. It can also help to unclog pores and prevent acne breakouts.

Retinoid vs Retinol, what is the difference?

Retinoids and retinols are both derivatives of vitamin A and are used in skincare products to promote skin health and combat signs of ageing.

However, there are some key differences between the two. Retinoids are a class of vitamin A derivatives that are available only by prescription. They include tretinoin, adapalene, and tazarotene, among others. Retinoids are highly effective at treating acne and reducing the appearance of fine lines and wrinkles, as well as improving skin texture and tone.

They work by binding to retinoic acid receptors in the skin, which regulate gene expression and stimulate cell turnover and collagen production.

Retinols, on the other hand, are a milder form of vitamin A that are available over the counter. Retinols are less potent than retinoids, but they still offer many of the same benefits. They work by converting to retinoic acid once they are absorbed into the skin, and they can help to reduce the appearance of fine lines and wrinkles, improve skin texture and tone, and promote a more youthful-looking complexion.

In summary, while both retinoids and retinols are effective ingredients in anti-ageing skincare, retinoids are prescription-strength and more potent, while retinols are available over the counter and less potent.

Azelaic Acid

Azelaic acid is a naturally occurring dicarboxylic acid that is derived from grains, such as wheat, rye, and barley. It has antibacterial, anti-inflammatory, and antioxidant properties, making it a versatile ingredient in skincare.

Azelaic acid is commonly used to treat acne and rosacea, as it can help to reduce inflammation and redness, unclog pores, and regulate sebum production. It also has skin brightening properties and can be used to improve the appearance of hyperpigmentation, such as dark spots and melasma.

In addition to its anti-acne and brightening benefits, azelaic acid is also a gentle exfoliant that can help to smooth and refine the skin’s texture, reduce the appearance of fine lines and wrinkles, and promote a more youthful-looking complexion.

Azelaic acid is available in various concentrations, ranging from over-the-counter products to prescription-strength creams and gels. It is generally well-tolerated by most skin types, but it may cause some mild irritation or dryness in some individuals, particularly at higher concentrations.

Hyaluronic Acid

Hyaluronic acid is a naturally occurring substance in our bodies that plays a vital role in keeping our skin looking plump and hydrated.

It is a powerful humectant, meaning it can attract and retain up to 1000 times its weight in water, making it an essential ingredient in many skincare products.

Hyaluronic acid is used in skincare to hydrate the skin and improve its texture, leaving it looking smooth, supple, and youthful.

As we age, our natural levels of hyaluronic acid start to decline, leading to dryness, fine lines, and wrinkles. By using skincare products that contain hyaluronic acid, we can help to replenish and maintain our skins hydration levels, reducing the appearance of fine lines and wrinkles and promoting a more radiant complexion.

Hyaluronic acid is suitable for all skin types and can be found in a variety of skincare products, including serums, moisturisers, and sheet masks. It is a gentle ingredient that works by attracting and holding onto moisture, making it a great choice for those with dry, dehydrated, or mature skin.

With regular use, hyaluronic acid can help to improve the overall health and appearance of your skin, leaving it looking and feeling soft, smooth, and hydrated.

Niacinamide

Niacinamide, also known as vitamin B3, is a water-soluble vitamin that is a powerful ingredient in skincare. It is known for its ability to strengthen the skin barrier, improve hydration, and reduce the appearance of fine lines, wrinkles, and hyperpigmentation.

Niacinamide works by increasing the production of ceramides, which are essential components of the skin barrier that help to prevent moisture loss and protect against environmental damage. It also helps to regulate sebum production, making it an effective ingredient for oily or acne-prone skin.

In addition to its moisturising and anti-ageing benefits, niacinamide has anti-inflammatory properties that can help to calm redness and irritation, making it a great ingredient for sensitive or reactive skin.

Niacinamide is a versatile ingredient that can be found in a variety of skincare products, including serums, moisturisers, and toners. It is generally well-tolerated by all skin types, and its gentle nature makes it a great choice for those with sensitive skin.

Ascorbic Acid

Ascorbic acid, also known as vitamin C, is a potent antioxidant that is essential for skin health. It is a water-soluble vitamin that can be found in various fruits and vegetables, and is a popular ingredient in skincare products due to its many benefits.

Ascorbic acid is used in skincare to help brighten the complexion, reduce the appearance of dark spots and hyperpigmentation, and promote a more even skin tone.

It works by inhibiting the production of melanin, which is responsible for dark spots and hyperpigmentation. In addition to its brightening benefits, ascorbic acid also helps to stimulate collagen production, which can improve the skins elasticity and reduce the appearance of fine lines and wrinkles.

Ascorbic acid is a versatile ingredient that can be found in various forms, including serums, moisturisers, and facial masks.

It is suitable for all skin types, but it is especially beneficial for those with dull, tired-looking skin, or those looking to reduce the appearance of fine lines and wrinkles.

With regular use, ascorbic acid can help to improve the overall health and appearance of your skin, leaving it looking brighter, smoother, and more youthful.
