What's the difference between lipid-soluble and water-soluble vitamin C?

Lipid-soluble vitamin C (like the ascorbyl palmitate in C-ESTA) dissolves in oil rather than water, which allows it to penetrate the skin more effectively and remain stable longer. Traditional L-ascorbic acid is water-soluble and can be harsher and more prone to oxidation. The lipid-soluble form delivers similar brightening and antioxidant benefits with less irritation.

What does DMAE do for the skin?

DMAE (dimethylaminoethanol) is known for its firming and lifting effects. It helps tighten facial contours and reduce the appearance of sagging, which is why C-ESTA is often described as giving a "lifted" look to the skin over time.

Can I use C-ESTA with retinol or acids?

Yes, C-ESTA works well with most skincare ingredients because the lipid-soluble vitamin C is gentler than acidic forms. Apply C-ESTA first in the morning after cleansing, then follow with your other serums and moisturizer. If you use retinol, save it for your evening routine.

What does C ESTA face serum do?

C-ESTA Face Serum delivers a stable, lipid-soluble form of vitamin C deep into the skin to brighten, firm, and protect against environmental damage. The Marini C-ESTA formula combines ascorbyl palmitate with DMAE and hyaluronic acid to reduce the appearance of fine lines, improve skin tone, and boost radiance. Clinical studies show visible improvements in firmness, clarity, and overall skin health with consistent use.

What does vitamin C serum do for your face?

Vitamin C serum brightens your complexion, reduces the appearance of dark spots, and helps protect against free radical damage from UV exposure and pollution. The C-ESTA Face Serum uses ascorbyl palmitate, a lipid-soluble vitamin C that penetrates deeper than water-soluble forms, delivering antioxidant protection where your skin needs it most. Regular use can improve skin tone, boost collagen production, and leave your face looking more radiant.

If you're looking for a vitamin C serum that delivers results without irritation, Marini C-ESTA Face Serum is one I recommend often. Unlike traditional L-ascorbic acid formulas that can be harsh and unstable, this one uses a lipid-soluble form of vitamin C (ascorbyl palmitate) that absorbs better and stays stable longer.

What makes C-ESTA stand out is the combination of vitamin C with DMAE, an ingredient that helps firm and lift facial contours. Clients notice smoother texture, reduced fine lines, and a brighter overall glow. It works for all skin types and has that signature scent people either love or remember.

About Marini C-ESTA Face Serum

Formerly known as Jan Marini, the Marini SkinSolutions C-ESTA Face Serum is a cult-favorite antioxidant treatment that combines lipid-soluble vitamin C with DMAE, hyaluronic acid, and vitamins B5 and E. In a split-face clinical study published in the Journal of Drugs in Dermatology, C-ESTA showed statistically superior improvement in skin texture compared to a leading vitamin C alternative, and most subjects preferred its feel and application.

The lipid-soluble form of vitamin C in this formula penetrates more effectively than traditional water-soluble versions, meaning you get powerful antioxidant benefits without the harsh acidity that can cause irritation. DMAE enhances the firming effect, helping facial contours appear tighter and more lifted over time.

This 1 oz serum is paraben-free, vegan, and works well for all skin types. Browse our full collection of Marini vitamin C and antioxidant products.
