Collection: Skin Care Products With Ethyl Ascorbic Acid

Ethyl ascorbic acid is a stabilized derivative of vitamin C, known as a powerful antioxidant in skincare. It helps even out skin tone, reduce the look of dark spots and protect the skin against the damage caused by free radicals. It also supports collagen production, helping skin become firmer and more elastic. Suitable for all skin types including sensitive skin, it is known for its brightening effect. When choosing a product, you can compare ingredients and formats in the products with vitamin C category.

What Is the Difference Between Ethyl Ascorbic Acid and Ascorbic Acid?

Ascorbic acid is the form written as "Ascorbic Acid" in INCI lists, also known as pure vitamin C. It is an effective antioxidant, but it can oxidize easily on contact with air, light and water. That is why storage conditions matter for serums containing ascorbic acid. The label of the vitamin C serum in the sets on this page also recommends storing it in the refrigerator, without freezing.

Ethyl ascorbic acid, on the other hand, is a derivative obtained by attaching an ethyl group to the ascorbic acid molecule, and appears in the INCI list as "Ethyl Ascorbic Acid" or "3-O-Ethyl Ascorbic Acid". This change makes the molecule more resistant to light and air. Although the two ingredients come from the same family, they are not the same substance; you can check which one a product contains in the ingredients list on the packaging.

The ingredients list of the vitamin C serum in the sets listed on this page contains "Ascorbic Acid", that is, ascorbic acid, not "Ethyl Ascorbic Acid". In the serum's formula, ferulic acid is present alongside ascorbic acid. When choosing a product, you can compare ingredients and formats in the ferulic acid category.

The common product of the four sets in this category is the vitamin C serum containing ascorbic acid and ferulic acid. Alongside this serum, the sets include a peel with AHA and BHA, an arbutin serum, a glycolic acid toner or an enzyme powder peel. The ingredients lists of these products do not contain ethyl ascorbic acid either. Prepared for different skin needs, these sets are ideal for supporting your daily skincare routine.

The difference between ethyl ascorbic acid and ascorbic acid is mostly about the durability of the formula. Which step of the routine a product belongs in, and how often, is determined more by its form than by its ingredient. Whether it is a serum, a cream or an eye-area product, follow the usage instructions on the packaging.

In the sets on this page, vitamin C comes as a serum containing ascorbic acid: 1-2 drops are applied to cleansed skin, not rinsed off, and it can be used at night or during the day. The peel, toner and powder peel in the sets enter the routine at different frequencies; the instructions for each are on its own packaging. Do not skip sunscreen during the day while using the serum.

The Purest Solutions offers its vitamin C products at prices to suit every budget, providing effective and accessible skincare solutions. Among different products such as face serums, sets and moisturizers, you can choose the one that suits your needs and give your skin the best care. With regular use, you may notice your skin tone balancing and your skin taking on a brighter look.

Ascorbic acid is the pure form of vitamin C and appears in products' ingredient lists as Ascorbic Acid. Ethyl ascorbic acid, by contrast, is a chemically modified derivative of ascorbic acid; its INCI name is 3-O-Ethyl Ascorbic Acid. This change in its structure helps increase its resistance to oxidation. However, the two ingredients are not the same substance and should not be used interchangeably in product descriptions.

The Purest Solutions Brightening and Skin Tone Evening Vitamin C Skin Serum's ingredient list contains Ascorbic Acid. The formula also includes ferulic acid, glycerin and hyaluronic acid derivatives. This serum should not be described as a product containing ethyl ascorbic acid.

The published ingredients lists of the Microneedle Technology Brightening & Anti-Fine Line Under-Eye Patch and the Microneedle Technology Firming & Anti-Fine Line Forehead Patch, on the other hand, contain ethyl ascorbic acid. The formulas of these patches also include niacinamide, Centella Asiatica leaf extract and the peptide Acetyl Hexapeptide-8. Therefore, a comparison should take into account both the form of vitamin C used and whether the product is a serum or a targeted-area care patch.

The way products with ethyl ascorbic acid are applied depends on the product form. The Purest Solutions microneedle under-eye and forehead patches containing this ingredient are applied, after cleansing is complete, to clean, dry skin.

Microneedle Technology Brightening & Anti-Fine Line Under-Eye Patch: Wash and dry your hands and face. Place the patch on the under-eye area and hold it with light pressure for 10–15 seconds to secure it. Leave it on your skin for at least 6 hours, preferably overnight. The patch is single-use; do not reapply it after removing it.

Microneedle Technology Firming & Anti-Fine Line Forehead Patch: Apply to a clean, dry forehead. Press lightly for 10–15 seconds and leave on for at least 6 hours, preferably overnight. Store unused patches in their original resealable packaging in a cool, dry place.

For these products, the amount applied is not measured in drops; a patch made for the relevant area is used. Since the product pages do not state a weekly frequency of use, follow the packaging instructions for frequency.

The form of vitamin C used in The Purest Solutions products varies according to the product's ingredients list. The Brightening and Skin Tone Evening Vitamin C Skin Serum contains Ascorbic Acid, while the microneedle under-eye and forehead patches contain ethyl ascorbic acid. A set that includes a vitamin C serum cannot be said to contain ethyl ascorbic acid for that reason alone. When choosing a product, consider the vitamin C form in the ingredients list and the product's application area together.
