Steadiness: Really secure; significantly less at risk of oxidation in comparison with pure Vitamin C
Penetration: Its oil-soluble mother nature allows it to penetrate deeper in to the skin, reaching the lipid layer for Increased effectiveness.
Principal Positive aspects:
Powerful antioxidant action

Provides anti-aging benefits by smoothing fine strains and wrinkles
A lot less annoying plus much more well suited for delicate skin kinds
Use: Popular in anti-getting old and brightening serums, creams, and sunscreens.
two. Ethyl Ascorbic Acid:
Solubility: Drinking water-soluble
Stability: Reasonably steady in comparison with pure ascorbic acid; a lot more secure than L-ascorbic acid but considerably less stable than Ascorbyl Tetraisopalmitate.
Penetration: As a h2o-soluble kind, it Ethyl Ascorbic Acid works very well in hydrophilic environments and is also successful within the higher layers with the skin.
Main Added benefits:
Robust brightening effects by inhibiting melanin generation
Successful antioxidant that guards in opposition to no cost radicals
Supports collagen synthesis, marketing firmness and elasticity

Key Discrepancies:
Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, making it appropriate for oil-dependent formulas and deeper skin penetration, While Ethyl Ascorbic Acid is h2o-soluble, ideal for lightweight, water-primarily based solutions.
Stability: Ascorbyl Tetraisopalmitate tends to be far more steady, particularly in extensive-term formulations, although Ethyl Ascorbic Acid is much more steady than pure Vitamin C but can however Ascorbyl Tetraisopalmitate degrade eventually.
Pores and skin Sensitivity: Ascorbyl Tetraisopalmitate is normally gentler and not as likely to cause irritation, whilst Ethyl Ascorbic Acid is appropriate for a lot of pores and skin forms but can be a little bit more annoying for pretty delicate pores and skin.
