AHA and BHA are two of the most popular exfoliating acids in skincare. They help with dull skin, acne, pigmentation, blackheads, uneven texture and clogged pores — making them favourites for Indian skin that deals with dust, pollution, sun exposure and humidity.

But even though AHA/BHA are incredibly effective, they are also two of the most misused ingredients in skincare. Most people jump into exfoliating acids with excitement but without understanding how they work. This leads to irritation, purging, sensitivity, breakouts, damaged skin barrier, and uneven results.

In this blog, we break down the top mistakes people make about AHA BHA, why they happen, and how to avoid them so you can use acids safely and effectively — even as a beginner.

Mistake 1: Using AHA/BHA Too Frequently

One of the biggest mistakes is using chemical exfoliants every day or too many times a week. AHA/BHA are powerful acids — they dissolve dead skin cells, unclog pores and smooth texture. But they also weaken the skin barrier if used too often.

Using AHA/BHA too frequently can cause:

• redness

• peeling

• irritation

• burning sensation

• increased sensitivity

• breakout flare-ups

• dryness

• skin becoming overly thin

Beginners should start with once a week, then slowly increase to once every 10 days or twice a week if needed.

Mistake 2: Using Strong Percentages Without Experience

Just because a product says “10% AHA” or “2% BHA” doesn’t mean you need it immediately. Higher percentages do not mean better results — they mean higher risk.

Strong acids can damage the barrier, especially in Indian weather where humidity and sun exposure are high.

Beginners should always start with:

• low-percentage AHA

• mild glycolic or lactic acid

• 1–2% BHA maximum

• beginner-friendly formulations

Let your skin build tolerance before jumping to stronger exfoliants.

Mistake 3: Layering AHA/BHA With Strong Actives

One of the most harmful mistakes is mixing exfoliating acids with other strong ingredients without knowledge.

Avoid combining AHA/BHA with:

• retinol

• high-strength vitamin C

• benzoyl peroxide

• strong niacinamide

• scrubs

• harsh toners

• peels

These combinations overwork your skin and cause severe irritation.

AHA/BHA should ideally be used alone in a routine, followed by a simple moisturizer.

Mistake 4: Using AHA/BHA on Damp Skin

AHA/BHA penetrate faster on damp skin, which may sound like a good thing, but for beginners, this drastically increases irritation. Applying acids on damp skin can cause:

• burning

• stinging

• redness

• sensitivity

• micro-tears

Always dry your skin completely before applying AHA/BHA.

Mistake 5: Not Using Sunscreen While Exfoliating

This is the most common mistake in India. AHA/BHA make your skin more sensitive to UV rays. If you exfoliate without sunscreen, you risk:

• dark spots

• pigmentation

• sunburn

• tanning

• uneven tone

• faster ageing

If you use AHA/BHA, sunscreen becomes mandatory — every single morning.

Mistake 6: Expecting Overnight Results

Many people think AHA/BHA will give instant glowing skin after one use. While acids can give quick brightness, the real benefits take weeks:

• smoother texture in 2–3 weeks

• fewer blackheads in 3–5 weeks

• reduced pigmentation in 6–10 weeks

• stronger barrier in 8+ weeks

Exfoliation is a slow, controlled process — not a magic shortcut.

Mistake 7: Using AHA/BHA for Every Skin Problem

AHA/BHA are powerful, but they are not the solution to every issue. They do NOT:

• remove deep pigmentation instantly

• cure acne completely

• shrink pores permanently

• fix sensitivity

• replace moisturizers

• heal inflamed skin

They are a supportive ingredient — not a miracle cure.

Mistake 8: Using AHA/BHA on a Damaged Barrier

If your skin is irritated, peeling, dry or inflamed, avoid acids completely. Exfoliating damaged skin causes severe irritation and prolongs healing.

Fix your barrier first with:

• ceramides

• niacinamide

• moisturizers

• soothing ingredients

Then slowly introduce acids again.

Mistake 9: Using Multiple Exfoliants at Once

Some people use:

• face scrubs + AHA

• peels + BHA

• exfoliating cleansers + exfoliating toners

• multiple acid serums in one routine

This leads to extreme barrier damage. Choose one exfoliating product and use it consistently.

Mistake 10: Not Moisturizing After AHA/BHA

Acids remove dead skin cells and increase cell turnover. If you don’t moisturize afterward, your skin becomes dry, tight and irritated.

Always follow AHA/BHA with a soothing, hydrating moisturizer to calm your skin and strengthen your barrier.

The Right Beginner-Friendly Way to Use AHA/BHA

Here’s the safest and simplest exfoliating routine:

Once a Week:

• Cleanser

• AHA/BHA (on dry skin)

• Barrier-repair moisturizer

On Other Days:

• Gentle cleanser

• Niacinamide or hydrating serum

• Moisturizer

• Sunscreen (morning)

This routine gives results without irritation.

Benefits You Get When AHA/BHA Are Used Correctly

When used safely and consistently, acids help with:

• smoother skin

• fewer blackheads

• fewer whiteheads

• brighter tone

• better texture

• reduced dullness

• less congestion

• faded acne marks over time

Healthy exfoliation = long-term glow.

Conclusion: AHA/BHA Are Powerful — But Only When Used Wisely

AHA and BHA can transform your skin — but only if used correctly. Avoiding the common mistakes, choosing the right percentage, exfoliating gently, using sunscreen and supporting your barrier are the foundation of a safe exfoliation routine.

When you respect your skin barrier and exfoliate mindfully, AHA/BHA become one of the most effective tools for clear, glowing, smooth skin.
