Vitamins in Cosmetics: A Complete Guide to Skincare

June 14, 2024

For centuries, we have learned the importance of vitamins for our overall health. Today, the use of vitamins in cosmetics can make a big difference when used in the correct dosage and in properly formulated products. When applied directly to the skin, vitamins offer a targeted approach to address various concerns and achieve a healthy, radiant complexion. Let's explore their benefits, compatibility with other ingredients, and essential precautions for the best results.

Vitamin A: On the Podium of Anti-Aging Cosmetics

Vitamin A, especially in the form of retinol and retinoids, is one of the most prominent when we talk about vitamins in cosmetics due to its anti-aging capacity. It stimulates collagen production, the vital protein for maintaining skin firmness. This translates into fewer wrinkles and fine lines, as well as improved skin texture and tone. It also helps fight acne and regulate sebum production.

Maximizing the benefits of vitamin A

Concentration is key: Concentrations of 0.2% to 1% are ideal for optimal results. However, the European Union has restricted retinol concentrations in over-the-counter products to 0.05% in body products and 0.3% in facial and hand formulas.
Correct storage: Choose products with packaging that protects the formula from light and air to preserve its potency.
The ideal partner: Vitamin A combines well with humectants such as hyaluronic acid or vitamin B5, and with some antioxidants such as vitamin C or E (applied at different times). We recommend seeking professional advice before combining it with other active ingredients.
Sun care: Vitamin A increases sun sensitivity, so daily use of a good sunscreen is essential. Therefore, we recommend introducing it gradually into your routine and applying it to dry skin to minimize irritation. If you are looking for a non-photosensitive alternative suitable for sensitive skin, we love Plant Perfection Gel Serum.

Vitamin B3: A Multifaceted Marvel

Vitamins in cosmetics, such as niacinamide (vitamin B3), are essential in any skincare routine. It addresses issues like hyperpigmentation, blemishes, and even wrinkles. This star ingredient controls oil production, making it a valuable ally for those with acne-prone skin.

For Optimal Results

Concentration matters: Look for formulas containing 2% to 10% niacinamide for best results, with 5% being ideal.
Team player: Niacinamide can be combined with most skincare ingredients, including humectants and antioxidants like vitamins C and E.
Sensitive skin? Choose wisely: For those with very sensitive skin, we recommend using niacinamide with exceptional purity and minimal nicotinic acid residue, such as that in Ultra Revitalising Elixir, to reduce any potential irritation.

Vitamin B5: Super Soothing

Pantothenic acid, known as vitamin B5 or panthenol, is a star moisturizing molecule for the skin. In addition, it promotes healing, reduces inflammation, and alleviates irritation caused by UV rays.

Usage Tips

Optimal concentration: 1% to 4% is the norm. Above this concentration, the product could be sticky.
Ideal combos: Vitamin B5 integrates well with other hydrating and restorative ingredients such as hyaluronic acid, glycerin, and ceramides. It can also be combined with antioxidant vitamins C and E for an additional layer of protection.

Vitamin B6: Ideal for Blemish-Prone Skin

Known as pyridoxine, vitamin B6 reduces excessive sebum production, which helps prevent acne. It also has soothing properties, making it highly sought after in after-sun formulas.

Low concentrations: It is effective at concentrations of 0.1% to 1%.
Recommended combinations: It combines well with botanical ingredients such as mallow and willowherb extract.

Vitamin B12: Very soothing but at a high cost

Cyanocobalamin, made by bacterial fermentation, helps soothe irritated skin and protect the skin barrier. It is a good option for people with sensitive skin who want to achieve a healthy appearance.

Challenges of Vitamin B12

Not only the price, which is around 15,000 euros per kg, can be an obstacle for formulators. Its limitations are not limited to how expensive it is.

Absolute precision: The quantity must be exact, as even a small difference of 0.01% in its concentration can change the final color of the product.
Better in the dark: It is light-sensitive and can be affected by strong acidity or alkalinity in water-based serums.

Vitamin C: The Inexhaustible Antioxidant

In the world of vitamins in cosmetics, vitamin C stands out as a powerful antioxidant. It protects the skin from radical damage and environmental aggressors. It brightens the complexion and promotes collagen production, contributing to a more youthful appearance.

Maximizing the power of vitamin C

Freshness is key: Due to its delicate nature, choose products in dark, airtight packaging to maintain its effectiveness.
Possible irritation: Vitamin C can be irritating in some cases. We recommend performing a patch test before use, especially if you have sensitive skin. (We recommend Ideal Brightening Corrective Serum as an alternative.)
Storage: Store products in cool, dry places.
Compatibility: It works well with vitamin E for increased antioxidant protection. Avoid using it with AHA/BHA to minimize irritation.

Vitamin D: For a strong barrier

Vitamin D itself is prohibited in cosmetics, but there are other ingredients with similar benefits, such as extracts from different peonies and cholecalciferol (vitamin D3).

Pure juggling: A balanced approach is essential to avoid unwanted reactions. Introduce it gradually to sensitive skin.
Compatibility: Vitamin D can be deactivated by AHA/BHA, as well as in slightly acidic formulas. Seek professional advice if you use these ingredients with vitamin D.

Vitamin E: Your natural shield

Vitamin E is probably the most well-known antioxidant in the world of cosmetics. It protects the skin from free radicals, aids in cell repair, strengthens the skin's barrier function, and soothes irritation.

Finding effective vitamin E products

Always works: We find it in formulations in doses ranging from 0.1% to 100%, and it never disappoints.
Synergy with other ingredients: Vitamin E works well with vitamin C to provide greater antioxidant protection. It also integrates with humectants and other antioxidants like Sodium PCA and other salts present in the natural moisturizing factor.

Vitamin F: The essential fatty acid blend

Vitamin F refers to a combination of essential fatty acids, such as linoleic and linolenic acid, crucial for healthy skin function. It strengthens the skin barrier and improves hydration. It is found in vegetable oils like safflower oil. Vitamin F is particularly beneficial for dry, stressed, or sensitive skin.

Biotin (Vitamin H): Back in the spotlight?

Biotin's popularity in skincare fluctuates over time. It is frequently promoted as a comprehensive solution for nail, hair, and skin health. Beauty experts claim that biotin can improve skin rashes, restore cracked skin, and maintain skin in perfect condition.

Vitamin K: For better skin tone

Vitamin K helps even out skin tone by reducing dark circles and hyperpigmentation. It is a gentle option for people with sensitive skin.

Using vitamins in cosmetics: General considerations

Don't experiment: A professional can assess your skin type and recommend the most effective topical vitamins for your specific case.
Ingredient compatibility: Most vitamins in cosmetics can be used together, although here their two are important. Special attention must be paid when combining vitamin A with other active ingredients. When in doubt, always consult your trusted professional.
Storage: Vitamins A, B3, B6, C, and E are extremely sensitive to light and air. Store them in cool, dry places and choose products with dark packaging to maximize their potency.

By incorporating vitamins into your routine, you can leverage their unique properties to achieve healthy, radiant skin. Consistency is key, so allow enough time to observe the full effects of each vitamin and do not hesitate to consult our team for personalized advice.
