Ascorbyl Tetraisopalmitate is a stable, oil-soluble derivative of Vitamin C. It’s commonly used in skincare products due to its antioxidant properties, which help protect the skin from oxidative stress caused by free radicals and environmental damage. Here’s how it works:
- Antioxidant Action: Ascorbyl Tetraisopalmitate acts as an antioxidant, helping to neutralize free radicals and reactive oxygen species (ROS) in the skin. This action helps protect the skin from oxidative stress, which can lead to aging, inflammation, and damage from UV radiation.
- Collagen Synthesis Stimulation: Like Vitamin C, Ascorbyl Tetraisopalmitate plays a role in collagen synthesis by stabilizing collagen molecules and promoting the production of collagen fibers. This can help reduce the appearance of fine lines and wrinkles, improving skin texture and elasticity.
- Skin Brightening: It has skin-brightening effects due to its ability to inhibit the enzyme tyrosinase, which is involved in melanin production. This can help in reducing hyperpigmentation, dark spots, and uneven skin tone, leading to a more radiant complexion.
- Fat-Soluble Vitamin C Benefits: Being fat-soluble, Ascorbyl Tetraisopalmitate can penetrate deeper layers of the skin (as opposed to water-soluble Vitamin C), which allows for better absorption and more prolonged action. It is more stable than ascorbic acid, particularly in products like serums or creams.
- Anti-Inflammatory: It has anti-inflammatory properties that help reduce irritation and redness in the skin, making it suitable for sensitive skin types or conditions like acne or rosacea.
Its lipophilic nature (ability to dissolve in fat) allows it to work effectively in the skin, delivering the benefits of Vitamin C without the irritation that is sometimes associated with water-soluble Vitamin C derivatives like ascorbic acid.

Uses of Ascorbyl Tetraisopalmitate
Ascorbyl Tetraisopalmitate is a stable, oil-soluble derivative of vitamin C (ascorbic acid). It’s commonly used in skincare products due to its antioxidant properties, and it offers several benefits for the skin:
- Brightening and Even Skin Tone: Ascorbyl Tetraisopalmitate can help reduce the appearance of hyperpigmentation, such as dark spots or melasma, by inhibiting melanin production. This leads to a more even skin tone over time.
- Anti-Aging: As a potent antioxidant, it neutralizes free radicals and protects the skin from oxidative stress, which can damage the skin and contribute to signs of aging like fine lines and wrinkles. It also promotes collagen production, improving skin elasticity and reducing the appearance of wrinkles.
- Improved Skin Barrier: This derivative is less likely to cause irritation compared to other forms of vitamin C, making it ideal for sensitive skin types. It helps reinforce the skin’s barrier, keeping it hydrated and protected.
- Stability: Unlike pure ascorbic acid, which can degrade quickly when exposed to air and light, Ascorbyl Tetraisopalmitate is more stable, meaning it can be incorporated into formulas without the risk of losing potency as quickly.
- Absorption: Because it’s oil-soluble, Ascorbyl Tetraisopalmitate can penetrate the skin more effectively than water-soluble vitamin C derivatives, delivering its benefits deeper into the skin layers.
It’s often found in serums, moisturizers, and sunscreens, especially in products targeting anti-aging or skin brightening. Since it’s stable, it’s a great option for anyone looking for a vitamin C derivative that works without the usual concerns about oxidation.
