Skincare acids are powerful, transformative ingredients that can take your skincare routine to the next level. In this blog post, I’m breaking down the basics, and helping you figure out how to incorporate these powerful ingredients into your skincare routine safely and effectively.

What Are Skincare Acids
Skincare acids are a category of skincare active ingredients used in various products to exfoliate, brighten, hydrate, and address specific skin concerns. Skincare acids are designed to improve your skin’s texture, tone, and overall health. They work by breaking down the bonds between dead skin cells allowing for easier exfoliation and revealing fresher, more radiant skin underneath.
Benefits of Skincare Acids
Despite their intimidating name, skincare acids can be your skin’s best friend. Here is why:
- Exfoliation: acids help remove dead skin cells, revealing smoother, brighter skin underneath.
- Acne control: certain acids can help unclog pores, reduce inflammation, and fight acne-causing bacteria.
- Hydration: some acids attract and retain moisture, keeping your skin plump and hydrated.
- Anti-aging: acids can stimulate collagen production, reduce the appearance of fine lines, and improve skin texture.
Sounds amazing, right? Let’s get to know some of the most popular skincare acids and what they can do for your skin.
Meet the Skincare Acids: A Beginner’s Guide
Alpha Hydroxy Acids (AHAs)
AHAs are water-soluble acids derived from fruits and milk. They are known for their exfoliating properties, making them a go-to for anyone looking to brighten their complexion. They are great for treating surface-level skin issues.
Popular AHAs:
- Glycolic acid: sourced from sugar cane, glycolic acid has the smallest molecular size, allowing it to penetrate deeply and work efficiently.
- Lactic acid: derives from milk, lactic acid is gentler than glycolic acid and perfect for beginners. It hydrates while exfoliating, making it suitable for sensitive skin.
- Mandelic acid: extracted from bitter almonds, mandelic acid has a larger molecular size, meaning it penetrates more slowly and gently. It is ideal for sensitive or acne-prone skin.
Benefits of AHAs:
- Exfoliate dead skin cells.
- Improves skin texture and tone.
- Reduces hyperpigmentation.
How to use AHAs:
Start with a low concentration (5 to 10%) and apply 1 to 3 times a week. AHAs can make your skin more sensitive to the sun, so always follow up with sunscreen during the day.
Beta Hydroxy Acids (BHAs)
BHAs are oil-soluble, making them perfect for oily and acne-prone skin. They can penetrate deeper into the pores, helping to clear out excess oil and debris.
Popular BHA:
- Salicylic acid: derived from willow back. It is a powerhouse for unclogging pores, removing excess oil, and dead skin cells.
Benefits of salicylic acid:
- Reduces acne and blackheads.
- Unclogs pores.
- Has anti-inflammatory properties.
How to use salicylic acid:
Salicylic acid is ideal for oily and acne-prone skin. You can find it in cleansers, toners, and spot treatment. Start with a product containing 1 to 2% salicylic acid and use it a few times a week.
Poly Hydroxy Acids (PHAs)
PHA’s are the new kids on the block. They work similarly to AHAs but have a larger molecular structure, making them gentle and suitable for sensitive skin.
Popular PHA’s:
- Gluconolactone: a gentle exfoliant that also has moisturizing properties.
- Lactobionic acid: known for its antioxidant properties and the ability to strengthen the skin barrier. Lactobionic acid not only exfoliates but also helps to protect the skin from environmental damage.
Benefits of PHAs:
- Gently exfoliates without irritation.
- Hydrates the skin.
- Suitable for sensitive skin.
Antioxidant-rich Acids
Ascorbic acid (the most popular variant of vitamin C) and ferulic acid are powerful antioxidants that promote cell turnover, brighten the skin, and stimulate collagen production. They are excellent for combating free radical damage and giving your skin a radiant glow.
Benefits:
- Fades hyperpigmentation.
- Brightens skin tone.
- Boosts collagen production.
How to use:
Vitamin C serums can be used daily in the morning. Apply it after cleansing and before sunscreen to enhance its protective benefits.
Hyaluronic acid
A non-exfoliant acid. Hyaluronic acid is a humectant, it draws moisture into the skin.
Benefits:
- Deep hydration.
- Plumps the skin.
- Reduces the appearance of fine lines.
How to use:
Hyaluronic acid can be used daily and is suitable for all skin types. Apply it after cleansing and before moisturizing to lock in hydration.

Benefits:
- Reduces redness and inflammation.
- Fights acne-causing bacteria.
- Evens out skin tone.
How to use:
It’s typically available in concentrations of 10 to 20%. Azelaic acid 10% is available in gels and creams over the counter. 15% to 20% azelaic acid requires a prescription. You can apply it once or twice daily, depending on your skin’s tolerance.
Most skincare acids are derived from natural sources and at-home skincare acids are mild and work only on the surface of your skin. They help with exfoliation and achieving a glow. They generally do not require any downtime and most do not actually “peel” your skin.
How to Incorporate Skincare Acids: A Beginner’s Guide
Now that you know the basics, let’s talk about how to incorporate these magical ingredients into your routine. Here are some beginner friendly tips:
1. Start Slow
When introducing acids into your skincare routine, less is more. Start with a lower concentration and gradually increase as your skin builds tolerance.
2. Patch Test
Before applying any new products to your skin, do a patch test. Apply a small amount to a discrete area (like behind your ears) and wait 24 hours to see if any irritation occurs.
3. Listen to Your Skin
Pay attention to how your skin reacts. If you experience irritation or excessive dryness, scale back the usage or switch to a milder acid.
4. Don’t Mix Acids Haphazardly
While some acids can be combined others shouldn’t be used together. For instance, using AHAs and BHAs together can be too harsh, except they are formulated together. A good rule of thumb is to alternate acids on different days.
5. Follow With a Moisturiser
Acids can sometimes be drying, so it’s essential to follow up with a good moisturizer to keep your skin hydrated or balanced.
6. Timing Matters
When you use acids in your skincare routine can impact their effectiveness. Vitamin C (ascorbic acid) is great in the morning to protect against environmental damage. AHAs on the other hand are best used at night when your skin is in repair mode. Always follow up with sunscreen during the day, as AHAs can make your skin more sensitive to the sun.
7. Don’t Overdo It
It’s tempting to use multiple acids to achieve faster results, but over exfoliating can damage your skin barrier. Stick to one or two acids in your routine and give your skin time to adjust.
8. Be Patient
Skincare acids can take a few weeks to show results. Consistency is key, so stick to your routine and be patient.
9. Use Sunscreen
Acids can make your skin more sensitive to the sun. Always apply a broad-spectrum sunscreen during the day to protect your skin from UV damage.

Potential Side Effects of Skincare Acids
