When it comes to achieving radiant, even-toned skin, science has proven that the right combination of ingredients can make all the difference. One such powerhouse duo is AHA/BHA and Vitamin C—a match made in skincare heaven for targeting dark spots, hyperpigmentation, and dullness.

In this article, we’ll dive deep into these three skin superheroes, explain their differences, and share how you can incorporate them into your routine for maximum results—and how OOTD Beauty harnessed the power of K-beauty technology and cutting-edge scientific research to create products that truly transform your skin.

The Exfoliating Power of AHA and BHA

Dark spots often linger because dead skin cells trap pigmentation under the surface. This is where AHA (alpha hydroxy acids) and BHA (beta hydroxy acids) help. These chemical exfoliants softly break down the glue-binding dead cells, showing new, healthy skin underneath.

Think of AHA as your go-to for surface-level issues, like dullness and rough texture, while BHA dives deeper to unclog pores and prevent breakouts. It’s like giving your skin a reset button.

Major Benefits of AHA: AHAs, such as glycolic and lactic acid, act only on the outer layer of your skin. They break the link between the dead skin cells, whereby they can easily be shed. Such a process assists in avoiding congested pores, or rather, a skin condition that brings about acne. Also, AHAs have been known to minimize post-acne scars and even out skin tone to afford your skin a clearer complexion.

• Improves skin texture and tone.

• Fades dark spots and hyperpigmentation.

• Smooth's fine lines and wrinkles.

Major Benefits of BHA: The BHAs, for example, salicylic acid, work at a deeper skin penetrative level than the AHAs. It emulsifies the comedogenic oils that block the pores and, hence, is suitable for individuals with oily skin. They also possess anti-inflammatory and antibiotic activity that helps decrease the redness and inflammation of acne. Due to its ability to penetrate deep into the skin, it removes dead skin cells, hence easing the cleaning of the pores to avoid future acne breakages.

• Reduces acne, blackheads, and clogged pores.

• Soothes redness and inflammation.

• Provides deep pore cleansing.

Why Is Vitamin C Your Skin’s Best Friend

Vitamin C is more than just a morning energy boost. This strong antioxidant works hard to brighten skin, lighten dark spots, and guard against free radicals. Think of it as a shield protecting you from harmful pollution while it fades acne marks. That’s what Vitamin C does.

However, not all Vitamin C products are the same. Some spoil quickly and others bother sensitive skin. At #OOTD Beauty, our Dark Spot Vitamin C Serum mixes pure Vitamin C with niacinamide (for brightening benefits). The result: a light, fast-absorbing formula that makes your skin glow without feeling oily.

It’s fragrance-free, so even sensitive skin might benefit. Unlike other brands, we’ve included calming ingredients to stop irritation, allowing you to enjoy the benefits without any problems. Why choose ordinary when you can have a serum designed for results? Customers love seeing the obvious changes in just a few weeks, like a smoother surface and a noticeable glow.

Can You Use Vitamin C and AHA/BHA Together?

While both Vitamin C and AHA/BHA are excellent for targeting dark spots and improving skin texture, they shouldn’t be used at the same time. Combining these active ingredients in one routine can over-exfoliate your skin and lead to irritation. Instead, here’s how to structure your routine: 

• AHA/BHA Products: Use as part of your exfoliation step during your nighttime routine. These acids gently slough off dead skin cells and speed up cell turnover, revealing brighter, smoother skin.

• Soothing and Hydrating Care: After exfoliating with AHA/BHA, follow up with calming products like the OOTD Beauty Peptide Cream or OOTD Vegan Hydrating Mask Pack. These products are designed to restore moisture, soothe irritation, and strengthen your skin barrier for optimal recovery.

• Vitamin C Products: Incorporate Vitamin C into your morning routine. It fights free radicals, boosts collagen production, and brightens your complexion, preparing your skin to face the day.

Tips for Safe Use

• Patch Test: Always patch-test new products to check for sensitivity.
• Avoid Overuse: Limit AHA/BHA use to 2–3 times per week to prevent over-exfoliation.
• Follow Up with Soothing Care: After using exfoliating acids apply hydrating and calming products to nourish your skin.
• Use Sunscreen: Both AHA/BHA and Vitamin C can increase your skin’s sensitivity to the sun, so daily SPF is non-negotiable.

Essential FAQs About AHA, BHA, and Vitamin C

1. What shouldn't you mix with Vitamin C?

Avoid combining Vitamin C with products containing retinol, benzoyl peroxide, or AHAs/BHAs in the same routine, as this can lead to irritation or reduce the effectiveness of the ingredients. Instead, use Vitamin C in the morning and other active ingredients at night.

2. What should you avoid when using AHA and BHA?

When using AHA/BHA, avoid combining them with retinol or Vitamin C in the same routine to prevent skin irritation. Also, steer clear of harsh physical exfoliants, as over-exfoliation can damage the skin barrier.

3. How often should I use AHA/BHA?

For most skin types, 2–3 times a week is sufficient. Sensitive skin types may need to start with once a week and gradually increase usage as the skin builds tolerance.

4. Is sunscreen necessary when using AHA, BHA, and Vitamin C?

Absolutely! These ingredients can make your skin more sensitive to the sun, so applying sunscreen daily is essential to protect against UV damage and prevent dark spots from worsening.

5. Can AHA/BHA cause purging?

Yes, it’s common to experience purging when starting AHA/BHA products as they accelerate the skin's cell turnover. This usually lasts 2–4 weeks and should subside as your skin adjusts.

6. What makes OOTD Beauty’s products better for using AHA, BHA, and Vitamin C?

At OOTD Beauty, our products are specially formulated to balance these powerful ingredients with soothing agents like aloe vera, green tea extract, and hyaluronic acid. This ensures effective results without compromising your skin’s barrier.

Wrapping Up

Dark spots and uneven tone don’t stand a chance when you follow a structured routine with AHA/BHA and Vitamin C. Use AHA/BHA for exfoliation and follow up with soothing products to keep your skin balanced and hydrated. Pair this with Vitamin C in the morning for a comprehensive approach to glowing skin.
