5 reasons why mandelic acid should be part of your skin care routine
Mandelic acid helps reduce acne and even out skin tone. Find out the benefits of this alpha hydroxy acid for your skin.
If you use skin care products to fight acne and prevent premature aging, you’ve probably come across an active ingredient called mandelic acid. This chemical peel agent is popular because it is gentle on the skin. It helps remove the top layer of skin cells and improve the appearance of the skin. By incorporating it into your daily skin care routine, you can solve various skin problems. However, before using it, you need to know the concentration and frequency of use. Failure to do so may cause skin irritation, redness, or peeling.
What is mandelic acid?
It is a type of alpha hydroxy acid, a group of acids that occur naturally in fruits, milk, and sugar cane. “Mandelic acid is derived from bitter almonds and is used in many skin care products because of its gentle exfoliating properties,” says dermatologist and cosmetologist Ashini Bhatt, Ph.D. Due to its gentle exfoliating properties, it is also suitable for those who suffer from acne and uneven skin tone.
What are the benefits of using mandelic acid on the skin?
It has become a popular choice for skin care routines as it provides a variety of benefits for the skin.
1. Reduces hyperpigmentation
Mandelic acid is effective in lightening age spots, melasma, skin diseases that cause spots on the face, and post-inflammatory hyperpigmentation. According to research published in the journal Dermatology Surgery in 2009, it is effective in eliminating hyperpigmentation. “By aiding skin cell turnover, it gradually brightens pigmented areas and makes your skin tone more even,” says the expert.

2. Acne treatment
Due to its antibacterial properties, mandelic acid is the perfect solution for acne-prone skin. According to an analysis published in Dermatology Review in 2015, skin care products containing 5 or 10 percent mandelic acid are safe and effective in treating acne. It helps eliminate acne-causing bacteria, reduces inflammation, prevents future breakouts, and maintains clearer skin.
3. Improves skin texture
It gently exfoliates the surface and helps to even out the skin’s texture. “This reduces roughness and minimizes large pores, giving your skin a smoother, more refined appearance,” says Dr. Bhatt. According to a 2018 study published in the journal Facial Plastic Surgery, this is a topical treatment option for improving skin quality.
4. Anti-aging effect
This acid acts as a powerful exfoliant, reducing the appearance of fine lines and wrinkles. According to an analysis published in Dermatology Review in 2015, it has excellent results when used to treat wrinkles. “It also stimulates collagen production, which improves skin elasticity and contributes to firmer, more youthful-looking skin,” says the expert.
5. Repairs skin from sun damage.
Mandelic acid is effective in repairing damage caused by the sun’s UV rays and environmental factors. “It helps fade sunspots (skin blemishes that appear due to excessive sun exposure), reduces skin tanning, and restores skin’s natural brightness,” experts say.
Salicylic acid vs. mandelic acid: which is better?
salicylic acid for skin
Salicylic acid, a beta-hydroxy acid, has a small molecular size that allows it to penetrate deep into the skin. “It effectively unclogs pores and controls sebum, making it ideal for oily and acne-prone skin,” says Dr. Bhatt. Salicylic acid’s comedolytic properties make it a useful exfoliant for people suffering from acne, according to a 2015 study published in Clinical, Cosmetic, And Investigational Dermatology. However, it can cause dryness and irritation, especially if you have sensitive skin types.
mandelic acid for skin
Mandelic acid (AHA), on the other hand, penetrates more slowly and is gentler and less irritating due to its larger molecular size. “It’s especially effective for people with sensitive skin or dark skin that is prone to hyperpigmentation,” says the expert. Additionally, mandelic acid improves skin texture, reduces acne, and brightens skin tone.
best skin care ingredients
A 2019 study published in the Journal of Cosmetic Dermatology found that a 45 percent mandelic acid peel was as effective as a 30 percent salicylic acid peel for people with mild facial acne. However, the safety and tolerability of mandelic acid peel was better than salicylic acid peel.
“While salicylic acid is good for deep pore cleansing and managing oily skin, mandelic acid is a gentler, more versatile option, suitable for sensitive skin or those looking to address hyperpigmentation and texture issues.” Dr. Butt says.
How can I use mandelic acid on my skin?
1. Beginners need to take their time
It can be used daily, but it depends on your skin type and tolerance. If you’re a beginner or have sensitive skin, it’s best to start slowly with a low concentration, using it every other night or a few times a week until your skin gets used to it. “It’s best to start using this AHA at 5% so your skin gets used to it gradually. If your skin is already used to AHAs like glycolic acid, lactic acid, and retinol, you might be able to tolerate 10%. However, we recommend a patch test,” says the expert. If you have sensitive or dry skin, 10 percent is generally not recommended as it can worsen dryness and irritation.

2. Start Mandelic Acid Slowly
Start slowly, using it once or twice a week, and increase the frequency as your skin gets used to it. AHAs increase your susceptibility to UV damage, so be sure to wear sunscreen during the day in conjunction with a moisturizing moisturizer.
3. Be careful
If you already incorporate other exfoliating products, such as retinol or benzoyl peroxide, into your skin care routine, you should use mandelic acid with caution as it can lead to over-exfoliation.
4. Follow a routine
First, we recommend starting with a low concentration of mandelic acid, especially in your night skin care routine. After cleansing your face with a gentle, mild cleanser, apply a mandelic acid serum, followed by a moisturizer to lock in moisture and support your skin’s barrier. This approach allows your skin to benefit from exfoliation without becoming irritated.
What are the side effects of using mandelic acid on the skin?
The side effects of this acid vary depending on its concentration and how it is used. It’s important to gradually introduce it into your skin care routine, starting with once a week and seeing how your skin tolerates it.
- If used in high concentrations on dry skin or applied nightly, it can cause rashes and irritation.
- Your skin may also feel dry.
- Skin peeling is also a potential side effect.
Mandelic acid helps improve skin texture, reduce acne, reduce pigmentation, and promote an even skin tone. Anyone can use it, but it’s especially effective for people with oily or acne-prone skin. However, it is best to consult a dermatologist before introducing new skin care products into your daily regimen.
