The following are practical suggestions for "choosing acid-based skin care products" based on the content of the article:

  1. Understand your needs first, then choose the right acid: When choosing acid-based skin resurfacing products, first, carefully evaluate your skin condition and needs. For example, if you have sensitive skin, you should choose gentle PHA products instead of more irritating AHA or BHA. If you want to improve acne problems, you can use BHA products containing salicylic acid.
  2. Take it step by step and slowly build up tolerance: Don’t blindly pursue high concentrations. Start with low-concentration, mild formulas, observe skin reactions, and slowly build up tolerance. For example, you can start with a low concentration (such as 2%) of AHA products and use it once or twice a week. If your skin does not have an allergic reaction, you can gradually increase the frequency and concentration of use.
  3. Use moisturizing products to reduce irritation: Acid products will make the skin's stratum corneum thinner, which can easily cause dryness and sensitivity. Choose moisturizing products suitable for the skin, such as products containing ingredients such as ceramide and hyaluronic acid. Apply moisturizing products immediately after using acid products to effectively lock in moisture and reduce irritation.

How to choose the right acid product?

Acid peels are like a gentle "deep cleansing" for the skin and have been a popular skincare trend in recent years. It can not only effectively remove dead skin cells, but also improve skin texture, brighten skin tone, and even has a significant effect on problems such as acne, enlarged pores, and blackheads. These effects all come from the different acids contained in acid products, such as the common AHA, BHA, PHA, etc. AHA (Alpha Hydroxy Acids) mainly comes from fruit and plant extracts, such as glycolic acid, lactic acid, mandelic acid, etc. They can effectively exfoliate, promote skin cell renewal, improve fine lines, wrinkles, uneven skin tone and other problems, and are suitable for dry and sensitive skin. BHA (Beta Hydroxy Acids) is represented by salicylic acid, which is oil-soluble and can deeply cleanse pores, remove oil and dirt, improve problems such as acne, pimples, and enlarged pores, and is suitable for oily and combination skin. PHA (Polyhydroxy Acids) is a milder acid. It has larger molecules than AHA and BHA and is less likely to irritate the skin. It also has antioxidant and moisturizing effects. It is suitable for sensitive skin or people who are trying acid peels for the first time.

Understand your skin and choose the right products!

 Everyone's skin is different, and with so many acid peels on the market, you may be wondering: which one is best for me? Choosing the right product can not only save you a lot of time on trial and error, but also make your skin care more effective.

What is your skin type?

  • Dry skin: dry, tight, and prone to peeling, requiring high moisturizing and repairing effects.
  • Oily skin: prone to oil production, large pores, and acne, requiring oil control and exfoliation functions.
  • Combination skin: Different areas of the face have different skin conditions, such as oily T-zone and dry cheeks, so different skin care products need to be selected for different areas.
  • Sensitive skin: prone to redness, stinging and itching, requires mild, low-irritation products.

What is your skin problem?

  • Acne and blackheads: You need products containing salicylic acid (BHA), which can penetrate deep into the pores to remove dead skin cells and dirt.
  • Dull and sallow complexion: You need products containing fruit acid (AHA), which can promote cell renewal and make the skin tone brighter.
  • Fine lines and wrinkles: Products containing peptides, vitamin C or high-concentration fruit acids are needed to promote collagen production and improve fine lines.
  • Large pores: You need products containing salicylic acid (BHA) or mandelic acid (AHA) to shrink the pores.

Here are some common types of acid peels:

  • Fruit acid (AHA) : The main function is to remove aging cuticles, promote cell renewal, and improve uneven skin tone, dullness, fine lines and other problems. Common fruit acids include glycolic acid, lactic acid, mandelic acid, etc.
  • Salicylic acid (BHA) : The main function is to remove dirt and oil from the pores, improve acne, blackheads, enlarged pores and other problems.
  • Polyhydroxy acid (PHA) : Compared with AHA and BHA, PHA molecules are larger and less irritating, making them suitable for sensitive skin.
  • Other acids: There are other acids like azelaic acid, glycyrrhizic acid, etc. which have anti-inflammatory and antibacterial properties.

When choosing an acid product, please select the appropriate concentration and ingredients based on your skin condition and needs. For those who are trying acid peels for the first time, it is recommended to start with a low concentration and gradually increase the concentration and frequency of use.

Choosing acid-based skin care products: starting from the needs of the skin

In addition to understanding the properties of acids, you also need to consider your own skin condition, for example: do you have oily skin, dry skin, sensitive skin, or acne-prone skin? Different skin conditions require different acids and concentrations. For example, oily skin can choose a higher concentration of BHA to control oil and remove acne, while sensitive skin needs to choose a low concentration of PHA or a mild AHA to avoid irritation. When choosing an acid product, you can start with a low concentration, slowly observe your skin's reaction, and then gradually increase the concentration. If you experience any skin discomfort such as redness, stinging, dryness, etc., you should stop using it immediately and consult a dermatologist.
