16 Tips before buying fruit acid products

Dec 20,2021 | HISEEK PRETTY

Alpha Hydroxyl Acid (AHA) is a variety of organic acids extracted from fruits and is an active ingredient found in a variety of natural fruits or yogurts. It includes grape acid, malic acid, citrus acid, and lactic acid, etc. It is called fruit acid because most of them is extracted from fruits. Among them, glycolic acid extracted from sugar cane is the most widely used.

Whenever physicians recommend the use of acidic care products or fruit acid treatment, many patients will respond, "Long-term use of fruit acids is not good for the skin, right? Many patients respond, "Will fruit acids make the skin sensitive?", "Will fruit acids make the skin sensitive? The answers to these questions are gathered here so that you can have a quick understanding of fruit acids in cosmetics and their use before buying fruit acid products.

1. There are various kinds of fruit acids, the most commonly used fruit acids in cosmetics are glycolic acid and lactic acid. In skincare products, fruit acids can play a role in exfoliation, whitening, acne, moisturizing, etc.

2. Lactic acid is often added to products as a pH-regulating ingredient, so don't think that just because you see lactic acid on the ingredient list that the product can play the many roles of fruit acids. On the contrary, if you see glycolic acid in the front of the ingredient list, it is likely that this product is a fruit acid product. This time for you to distinguish several different acid skincare

3.Glycolic acid, which is also the most readily available fruit acid product on the market today. Generally speaking, if used as a daily combination, the fruit acid product you purchase has a concentration of 4%-8%. Too low may not be effective enough, too high may be too pronounced because of side effects and difficult to use for a long time. So for newcomers or those who expect to maintain stable long-term use, a concentration of about 5% is the best choice.

Of course, now there are many brands that will be through special technology (such as slow-release) to make the product concentration higher, such as 20% or 30% (higher I have also seen), although I myself do not feel how irritating or side effects more powerful, I do not recommend new hands to try such a high concentration of products. One of the core principles of using acid: gradual!

4. Amygdaline: Amygdaline is the first generation of fruit acids, with the highest affinity to the skin, and has a good bactericidal ability to prevent inflammation and bacterial infection, so the feeling for the skin is more gentle and non-irritating, and does not produce the phenomenon of redness and swelling.

5. Salicylic acid: Salicylic acid has the effect of removing oil and exfoliating, the disadvantage is that the skin is more prone to dryness and needs to be moisturized after use, otherwise it is easy to have tightness and peeling phenomenon.

6. Azelaic acid: Azelaic acid is actually not a member of the fruit acid family. It is mostly made into an ointment and applied to help the skin metabolize keratin, sterilize, and lighten melanin for a healthier, fairer complexion, However, in patients with lupus erythematosus and crabapple constitution should avoid utilizing azelaic acid.

7. The lower the pH value, the more effective the fruit acids are. However, the national law requires that the pH of fruit acid products be greater than 3.5 to reduce the irritation of fruit acids on the skin.

8. Concentration Fruit acid products also need to be added at a certain concentration in order to play a good role in peeling. The maximum added concentration is 6% according to national regulations.
9. Irritation The irritation of fruit acids can be accepted by many people under the concentration (<6%) and pH conditions (pH>3.5) specified by the national regulations. However, care should still be taken with sensitive skin. It is recommended to use this link for a preliminary test to understand your skin sensitivity level.
10. Fruit acid for blackhead removal Fruit acid (glycolic acid) is difficult to produce the rapid effect of blackhead export at the legally required concentration and pH. However, it is claimed that some domestic cosmetic companies are able to modify corporate regulations to be approved by some methods and list products with pH below 3.5 with corporate standards. This makes it possible to have a blackhead expelling solution with visible effects.

11. Dealing with pores and blackheads Fruit acid (glycolic acid) products at legal concentrations and pH levels do not have a significant effect on pore reduction, but still have a positive effect. When dealing with pores and blackheads, consider also using a 2% salicylic acid product to alleviate these skin problems (2% is also the maximum concentration of salicylic acid allowed).

12. Anti-acne Fructis acid (glycolic acid) products will have a soothing effect on non-inflammatory acne.

13. Use with sunscreen products After the concentration of fruit acids exceeds 3%, it is recommended to use sunscreen products. Responsible companies will indicate this on the label of such products.

14. daytime or nighttime use Fruit acids (glycolic acid) can be used both day and night. fruit acids are not photosensitive but will cause your stratum corneum to renew faster and be more susceptible to UV damage. This is the reason why you have to use it together with sunscreen products during the day.

15. Collagen and fruit acids at the concentrations specified in the regulations have a negligible effect on stimulating collagen growth.

16. How to use products with concentrations beyond cosmetic regulations All products with pH levels or concentrations beyond those permitted for cosmetic use should be used with caution under the guidance of a physician or professional.

In fact, with the correct application procedure, fruit acids do not make the skin fragile and sensitive.

Because the maintenance effect of fruit acids, in low concentration, can promote the metabolism of keratin, prevent and improve acne, pimples, pore size problems, make the skin bright and shiny.

The high concentration of fruit acids can penetrate deep into the dermis of the skin and stimulate the growth of collagen tissue, which will make the skin layer thicker for a long time, making the skin firm and elastic, and improving the problem of fine lines, so there is no problem of fragile or thin skin.
