If there is one group of ingredients that can genuinely transform your skin, it is exfoliating acids. They unclog pores, smooth rough texture, brighten dullness, fade pigmentation, and bring back that healthy, confident glow we all want.

But with names like AHA, BHA, LHA, and PHA, most people do not know where to begin. And I get it. The world of chemical exfoliants can feel intimidating.

This GlowNote simplifies everything. You will learn what each acid does, how to use it correctly, who it is suitable for, and how to build an acid routine safely and effectively.
By the end, you will know exactly which exfoliating acid your skin needs and why.

What Are Acids and Why Are They Used in Skincare?

Acids are chemical exfoliants that dissolve the bonds holding dead skin cells on the surface. This creates smoother, brighter, clearer skin, without the irritation that physical exfoliants can cause.

These ingredients are among the most researched and effective solutions for:

• uneven tone
• clogged pores
• dullness
• pigmentation
• breakouts
• rough texture
• dehydration
• early signs of aging

Acids also support natural cell turnover, improving the skin’s renewal cycle over time.

AHA: Alpha Hydroxy Acids

Your glow giver and surface smoother

What it is:
AHAs are water soluble acids that exfoliate the surface of the skin. They are some of the best ingredients for revealing radiance and improving texture.

Popular AHAs:
Glycolic acid
Lactic acid
Mandelic acid

Found in:
Sugarcane
Milk
Bitter almonds

Best for:
Dry skin, dull skin, pigmentation, uneven tone, early fine lines.

How AHAs work:
They remove dead skin from the surface and promote epidermal turnover, which supports a smoother, brighter and more even complexion.
AHAs also improve the absorption of the next products in your routine.

How to use:
Use in the evening and follow with moisturiser. Always apply SPF during the day.

BHA: Beta Hydroxy Acids

Your pore purifying, acne clearing solution

Most common BHA:
Salicylic acid

Comes from:
Willow bark

Best for:
Oily skin, congested pores, blackheads, whiteheads, breakouts.

How BHAs work:
BHAs clear oil and dead skin inside the pores. They also have natural anti-inflammatory properties, which makes them ideal for breakout prone skin.

How LHA works:

Safe for daily use. Ideal for beginners or sensitive skin types.

Best for:
Sensitive skin, rosacea, eczema prone skin, dry or dehydrated skin, and compromised barriers.

How PHAs work:
PHAs gently exfoliate, hydrate the skin, strengthen the barrier, and reduce inflammation.

How To Add Acids Into Your Routine Safely

If you want glowing, balanced skin, slow and steady will always win.

1. Start with two or three nights a week.
2. Use only one acid at a time when beginning.
3. Avoid layering acids with retinol until your skin is used to both.
4. Be cautious when combining acids with vitamin C, as irritation can increase.
5. Keep your routine simple to prevent over exfoliation.
6. Moisturise well to support the barrier.
7. Apply SPF every single morning without fail.
