What Are Skincare Acids?

Skincare acids are active ingredients designed to exfoliate, hydrate, or target specific skin issues. They work by penetrating the skin’s surface, breaking down dead cells, and encouraging cell turnover.

Acids are typically categorised into three main groups:
 

• Alpha Hydroxy Acids (AHAs): Water-soluble acids that exfoliate the skin’s surface, improve texture, and promote radiance.
• Beta Hydroxy Acids (BHAs): Oil-soluble acids that penetrate deeper into the pores to unclog and fight acne.
• Polyhydroxy Acids (PHAs): Gentle exfoliants with hydrating properties, suitable for sensitive skin.

You can opt for ToneOp Care’s Skin 360 Tablets, an age-defying 360 skincare product for glowing skin, reduced pigmentation, treating acne and skin disorders, and promoting even skin tone.

8 Types Of Skin Acids For Your Skincare Routine

8 best types of skin acids for your skincare routine are:

1. Glycolic Acid: The Radiance Booster

Glycolic acid, an AHA derived from sugarcane, is known for its small molecular size, which allows it to penetrate the skin effectively. It removes the upper layer of the skin to uncover a more even, radiant appearance. It helps curb the visibility of fine lines and under-eye wrinkles and improves skin texture and tone.

Best For:

• Normal skin type
• Dry skin
• Combination skin types.

Avoid if you have very sensitive or reactive skin.

How To Use:

• Start with a low concentration (5-10%) in a serum, toner, or cleanser.
• Apply it at night and always use sunscreen during the day since glycolic acid may increase your skin's sensitivity to UV light. 
   

2. Salicylic Acid: The Acne Fighter

Salicylic acid, a BHA derived from willow bark, is renowned for its ability to penetrate and clear clogged pores. It actively targets blackheads, whiteheads, and acne. Salicylic acid reduces inflammation and redness and controls excess oil production.

Best For:

• Oily skin
• Acne-prone skin
• Combination skin

How To Use:

• Add salicylic acid to your regimen through cleansers, targeted treatments, or serums.
• Utilise it 2-3 times weekly at first and raise the frequency if well-tolerated. 
   

3. Lactic Acid: The Gentle Exfoliator

Lactic acid, an AHA derived from milk or fermented plants, is milder than glycolic acid and ideal for those with sensitive skin. It gently exfoliates to improve skin texture, hydrates the skin while promoting cell turnover and fades dark spots and discolouration over time.

Best For:

• Dry skin
• Sensitive skin

How To Use:

• Opt for a serum or exfoliating treatment containing 5-10% lactic acid. Apply at night and avoid using it alongside other strong exfoliants.
   

4. Hyaluronic Acid: The Hydration Hero

Being a humectant, hyaluronic acid attracts water to the skin, making it moisturised and plump. In contrast to other acids, it does not promote exfoliation. Instead, it seals in moisture and moisturises deeply. It is well known that hyaluronic acid increases the suppleness and elasticity of skin. It minimises the visibility of fine lines resulting from a lack of moisture. 

Best For:

• All skin types, including dehydrated skin.

How To Use:

• Use hyaluronic acid serums or moisturisers morning and night.
• Pair it with a hydrating mist or damp skin for maximum effectiveness.

5. Mandelic Acid: The Dark Spot Corrector

Mandelic acid, an AHA sourced from bitter almonds, features a larger molecular structure, resulting in a mild effect on the skin. It reduces hyperpigmentation and melasma, improves skin texture without irritation, and balances oil production, making it great for acne-prone skin.

Best For:

• Sensitive skin
• Acne-prone
• Combination skin

How To Use:

• Begin with a concentration ranging from 5-10% in a serum or exfoliant.
• Apply at night and consistently combine with sunscreen throughout the day. 
   

6. Azelaic Acid: The All-Rounder

Barley and wheat are two examples of grains that naturally contain azelaic acid. It possesses antibacterial and anti-inflammatory characteristics. It addresses acne and rosacea by diminishing redness and swelling and fades post-acne marks and hyperpigmentation. Additionally, it enhances the general tone and texture of the skin.

Best For:

• All skin types
• Acne-prone skin
• Skin with rosacea or discolouration.

How To Use:

• Seek out azelaic acid in creams or gels that contain 10-15% concentrations.
• Take it every day or as needed, ideally in the morning. 
   

7. Kojic Acid: The Brightening Agent

What it is: Kojic acid is a by-product of fermentation processes, such as brewing sake. It restricts melanin production to brighten dark spots and create a uniform skin tone. It offers antioxidant benefits to shield against free radicals.

Best For:

• All skin types are concerned about hyperpigmentation. 

How To Use:

• Incorporate kojic acid into your serums or creams for your nighttime regimen.
• Combine it with additional brightening substances such as vitamin C for improved outcomes. 
   

8. Tranexamic Acid: The Pigmentation Fighter

A synthetic form of the amino acid lysine, tranexamic acid is well-known for its capacity to address recalcitrant pigmentation problems. It reduces melasma and dark spots, improves skin clarity and radiance and works well with other acids and active ingredients.

Best For:

• All skin types, especially those with melasma or persistent discolouration.

How To Use:

• Use tranexamic acid in serums or creams during the night. 
• Use alongside sunscreen to protect your progress.

How To Include Skincare Acids In A Routine?

A well-structured AM and PM skincare routine is essential for maintaining healthy, radiant skin. Your morning routine focuses on protecting your skin from environmental aggressors like UV rays and pollution, while the evening routine is all about repair and rejuvenation. Together, these routines create a balanced approach to skincare, addressing your skin's needs around the clock.

Try incorporating the above-mentioned skin acids into your AM - PM skincare routine, and here is how:

Morning (AM) Routine

• Hyaluronic Acid: Use it in the morning to hydrate and plump your skin. It performs effectively under makeup and sunscreen. 
• Azelaic Acid: Ideal for calming redness, treating acne, and fading dark spots. It’s gentle enough for daytime use.
• Tranexamic Acid: Use this in the morning for its brightening effects and to target stubborn pigmentation.
• Kojic Acid: To target dark spots, this can be used in the morning, but always follow with sunscreen.

Evening (PM) Routine

• Glycolic Acid: Best used at night to exfoliate, smooth texture, and brighten. It may cause your skin to become sensitive to the sun. 
• Salicylic Acid: Apply at night to unclog pores and treat acne. Use in cleansers or spot treatments.
• Lactic Acid: Gentle exfoliation works best overnight to refine and hydrate your skin.
• Mandelic Acid: Use at night for gentle exfoliation, especially if you have sensitive skin or pigmentation concerns.

Dietitian's Recommendation

As a dietitian, I suggest enhancing your skincare regimen with a diet abundant in nutrients that benefit the skin to boost the impact of skincare acids. Combining glycolic or lactic acid with foods rich in vitamin C (such as citrus and berries) may boost collagen production and improve skin brightness.

For those using salicylic acid to combat acne, prioritise the anti-inflammatory omega-3 fatty acids present in salmon, walnuts, and flaxseeds. Foods high in antioxidants, such as spinach, nuts, and green tea, can enhance the effects of kojic or tranexamic acid for skin brightening. Stay well-hydrated by drinking ample water and consuming a balanced diet to enhance skin health from the inside out.

The Final Say

Skincare acids are effective substances used to tackle numerous skin issues, including acne and hyperpigmentation, as well as dryness and signs of ageing. By recognising your skin type and issues, you can select the appropriate acid to improve your routine. Begin gradually, build thoughtfully, and consistently combine acids with moisturising products and sunscreen to prevent irritation.

Consistency and patience are essential for noticeable outcomes. Regardless of whether you choose exfoliating AHAs, pore-clearing BHAs, or hydrating humectants, using skincare acids properly can enhance your skin. Incorporate these powerful ingredients into your self-care routine to attain healthier, glowing, and more balanced skin. 

FAQs

1. What happens if I overuse acids?

Overuse can lead to redness, dryness, sensitivity, and a damaged skin barrier. If this happens, stop using acids and focus on soothing products like ceramide-based moisturisers and hydrating serums. Reintroduce acids slowly once your skin heals, starting with gentler options.

2. What is the best acid for acne?

Salicylic acid is the go-to for acne. It penetrates deep into pores, removes excess oil, and reduces inflammation. Azelaic acid is another great option for calming redness and treating acne marks. Use these acids in cleansers, spot treatments, or serums for targeted results.

3. Can I use acids every day?

Hydrating acids like hyaluronic acid can be used daily, even twice a day. Exfoliating acids (glycolic, salicylic) should start 2-3 times a week, then increase frequency if your skin tolerates them well. Overusing acids can damage your skin barrier, so always follow with a moisturiser and sunscreen.

4. Can I use multiple acids in one routine?

Yes, but with caution. Combine hydrating acids like hyaluronic acid with exfoliating acids (e.g., glycolic or salicylic). Avoid mixing strong exfoliants (AHAs and BHAs) or combining acids with retinoids. Alternate days for potent acids to prevent irritation. Layer gradually and observe your skin's tolerance.
