Using Vitamin C Serum as your Skincare Routine
| 02 December 2021
Vitamin C (L ascorbic acid) is one of the powerful natural antioxidants that help protect the skin from the negative effects of free radicals that attack and damage skin cells. In addition, it participates in the processes of collagen synthesis and has certain depigmenting properties (it helps to fight excessive pigmentation).
Vitamin C in facial care
The best times to use vitamin C-enriched cosmetics are autumn, winter, and spring. During these periods, due to constant climatic changes and other negative factors, the skin often suffers from dryness, looks dull and tired. Serum with vitamin C will help to improve metabolic processes in skin cells, even out the tone of the face, and return the skin to freshness and radiance.
You can find vitamin C in exfoliating products, masks, serums, and face creams – such products provide a good antioxidant effect, fight the signs of premature aging, and even repair damaged skin cells. Also, vitamin C moisturizes the skin well, prevents moisture loss, regulates the PH level, and strengthens the immune system of cells. In addition, ascorbic acid brightens and evens out the tone of the face, and also effectively copes with traces of post-acne, relieving inflammation and irritation.
For home use, beauticians recommend choosing products with a concentration of vitamin C from 5-10% to 20%. In order not to irritate the skin, it is better to increase the concentration gradually. Owners of sensitive skin need to use vitamin C products carefully – useful acid can cause itching, redness, and tingling, so first you should give preference to products with a low content of vitamin C in the composition.
It is recommended to apply care with vitamin C in the evening before going to bed, after which in the morning it is imperative to use a protective agent with an SPF factor in order to avoid the appearance of pigmentation because it has a pronounced whitening and brightening effect.
After washing and toning, you need to distribute the cream or a few drops of serum with vitamin C and wait about 10-15 minutes so that the product is absorbed and does not interfere with other treatments. Now you can start applying other necessary cosmetic products.
How does vitamin C serum work on the skin?
- Prevents premature skin aging.
- Intensively protects the skin from the negative effects of bad ecology and sun exposure: it helps to neutralize free radicals caused by ultraviolet and infrared radiation, harmful tropospheric ozone.
- The protective function of the skin is increased by 8 times.
- Reduces age-related signs.
- Visibly improves skin firmness.
- Promotes collagen synthesis.
- Reduces age spots.
How to use and combine with other cosmetics?
You can use cosmetics with vitamin C in the morning and in the evening. In the daytime, it provides reliable protection against free radicals and UV damage. Vitamin C Serum plus SPF is the perfect match.
There is an exception: during the day, it is better not to use water-based serums with one of the forms of vitamin C, L-ascorbic acid. Because of the water, they have an acidic pH and exfoliate the skin, making it more sensitive to UV light. It is better not to combine them with acids and retinol (both components cause a peeling effect) and niacinamide – you can get a reaction in the form of redness, peeling, and hypersensitivity.
But other derivatives of the vitamin can be used with retinol and acids. The team of renowned dermatologist Paula Begoun, referring to research, writes that the combination of vitamins A and C provides optimal results for the skin, and vitamin C enhances the effectiveness of retinoids.
It is advised to start with a 5-10% concentration to avoid irritation. The maximum concentration should not exceed 20%, otherwise, the vitamin is simply not absorbed by the skin.
How do I choose an effective formula for non-sensitive skin?
Vitamin C is an excellent ingredient with a proven track record. Vitamin C serum works perfectly with tocopherol (vitamin E) and ferulic acid – the combination that is most often found on the market today.
But there is one problem: Vitamin C is very unstable. It oxidizes rapidly in light and in contact with air, forming free radicals. So, instead of protecting the cells, it damages them. Cosmetic chemists have been working for several years to create formulas in which ascorbic acid would remain stable and at the same time show good results. Hence the variety of vitamin forms, formulas, and cosmetic formats.
The most effective form is L-ascorbic acid; in the list of ingredients, it is indicated as follows: ascorbic acid, L-ascorbic acid. It is extremely unstable, water-soluble, and only works at pH levels below 4. Hence another problem: at low pH levels, concentrated ascorbic acid exfoliates the epidermis and can irritate the skin. Vitamin E and ferulic acid are used to stabilize vitamin C in this form.
How do you know if a product with L-ascorbic acid will work?
The authors of the Chemist Confessions blog have compiled a list of such conditions. It is necessary that the pH of the product is not higher than 3.5; acid concentration – from 5 to 20%; plus there were stabilizing components (for example, vitamin E and ferulic acid). Although, if the vitamin is in powder or nanotechnology is used, the formula will also be stable.
Is vitamin C serum suitable for problem skin?
In general, due to its anti-inflammatory and brightening properties, vitamin C is included in the composition of cosmetics for problematic and prone to inflammation skin. However, the possibility of individual reactions cannot be ruled out – therefore it is better to carefully look at the manufacturer’s recommendations.
