Both Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid are well known derivatives of Vitamin C used in skincare formulations, but they've got unique Houses which make them suitable for different skin issues and formulations.
one. Ascorbyl Tetraisopalmitate:
Solubility: Oil-soluble
Stability: Hugely steady; fewer vulnerable to oxidation compared to pure Vitamin C
Penetration: Its oil-soluble mother nature enables it to penetrate deeper into the skin, achieving the lipid layer for Increased success.
Most important Rewards:
Potent antioxidant motion
Stimulates collagen output
Cuts down hyperpigmentation and evens pores and skin tone
Gives anti-getting older benefits by smoothing good lines and wrinkles
Much less irritating and a lot more appropriate for sensitive pores and skin styles
Use: Prevalent in anti-growing older and brightening serums, creams, and sunscreens.
2. Ethyl Ascorbic Acid:
Solubility: Water-soluble
Steadiness: Reasonably stable compared to pure ascorbic acid; extra steady than L-ascorbic acid but much less secure than Ascorbyl Tetraisopalmitate.
Penetration: Being a water-soluble sort, it works perfectly in hydrophilic environments which is successful in the upper levels from the pores and skin.
Primary Gains:
Robust brightening consequences by inhibiting melanin generation
Effective antioxidant that safeguards versus free of charge radicals
Supports collagen synthesis, promoting firmness and elasticity
Lightens dark spots and increases skin tone

Essential Variations:
Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, which makes it suitable for Ascorbyl Tetraisopalmitate oil-primarily based formulas and deeper skin penetration, While Ethyl Ascorbic Acid is drinking water-soluble, perfect for light-weight, h2o-based goods.
Balance: Ascorbyl Tetraisopalmitate tends to be additional secure, specifically in lengthy-phrase formulations, even though Ethyl Ascorbic Acid is much more steady than pure Vitamin C but can even now degrade eventually.
Pores and skin Sensitivity: Ascorbyl Tetraisopalmitate is normally gentler and not as likely to trigger irritation, while Ethyl Ascorbic Acid is ideal for numerous pores and skin types but might be somewhat much more irritating for very delicate skin.
Conclusion:
The two Ascorbyl Tetraisopalmitate and Ethyl Ascorbic Acid offer you exceptional Positive aspects as Vitamin C derivatives, but They Ascorbyl Tetraisopalmitate can be decided on determined by formulation wants. Ascorbyl Tetraisopalmitate is ideal for further penetration and oil-based mostly items, whilst Ethyl Ascorbic Acid works perfectly in drinking water-primarily based goods with a center on brightening and antioxidant defense.
