Both Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid are popular derivatives of Vitamin C used in skincare formulations, but they have got distinct properties that make them suitable for various skin concerns and formulations.

1. Ascorbyl Tetraisopalmitate:
Solubility: Oil-soluble
Stability: Highly secure; significantly less susceptible to oxidation compared to pure Vitamin C
Penetration: Its oil-soluble mother nature lets it to penetrate deeper in to the skin, achieving the lipid layer for Improved performance.
Most important Gains:
Powerful antioxidant action
Stimulates collagen production
Cuts down hyperpigmentation and evens pores and skin tone
Supplies anti-growing older Positive aspects by smoothing fantastic lines and wrinkles
Less annoying and much more appropriate for delicate pores and skin sorts
Usage: Frequent in anti-getting older and brightening serums, creams, and sunscreens.
two. Ethyl Ascorbic Acid:
Solubility: Water-soluble
Steadiness: Moderately secure when compared to pure ascorbic acid; far more secure than L-ascorbic acid but significantly less steady than Ascorbyl Tetraisopalmitate.
Penetration: Like a water-soluble kind, it really works properly in hydrophilic environments and is also effective while in the higher layers of your skin.
Key Advantages:
Solid brightening effects by inhibiting melanin creation
Helpful antioxidant that shields from cost-free radicals
Supports collagen synthesis, promoting firmness and elasticity
Lightens darkish places and increases pores and skin tone
Usage: Regularly located in brightening serums, light-weight formulations, and water-based mostly products and solutions.
Important Discrepancies:
Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, making it ideal for oil-dependent Ethyl Ascorbic Acid formulas and further skin penetration, Whilst Ethyl Ascorbic Acid is drinking water-soluble, perfect for lightweight, drinking water-centered products.
Stability: Ascorbyl Tetraisopalmitate tends to be a lot more steady, particularly in extensive-term formulations, although Ethyl Ascorbic Acid is much more steady than pure Vitamin C but can however degrade over time.
Pores and skin Sensitivity: Ascorbyl Tetraisopalmitate is generally gentler and not as likely to trigger irritation, although Ethyl Ascorbic Acid is appropriate for quite a few pores and skin sorts but may very well be a little bit more annoying for pretty delicate pores and skin.
Conclusion:
Each Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid provide superb Rewards as Vitamin C derivatives, but They may be selected according to formulation requirements. Ascorbyl Tetraisopalmitate is ideal Ethyl Ascorbic Acid for further penetration and oil-dependent merchandise, even though Ethyl Ascorbic Acid operates effectively in water-dependent items having a focus on brightening and antioxidant defense.
