AHA 7 Whitehead Power Liquid

What you need to know

This is a other with Glycolic Acid. The smallest alpha-hydroxy acid (AHA). Exfoliates dead skin cells on the surface, improves texture, and stimulates collagen over time.

Who should use this: If your concern is rough texture, dull skin, fine lines, or mild hyperpigmentation, this ingredient addresses that directly. 5-10% for daily use, 20-30% for peels (use sparingly). In a cleanser, contact time is too short for the percentage to matter.

This is a other with Niacinamide. A form of Vitamin B3 that reduces oil production, improves skin barrier function, and fades post-inflammatory hyperpigmentation. One of the most researched actives in skincare.

Who should use this: If your concern is oily skin, large pores, uneven skin tone, or acne marks, this ingredient addresses that directly. 2-5% is the research-backed range. Higher concentrations (10%) exist but have not shown significantly better results in studies.

This is a other with Sodium Hyaluronate. A humectant that holds up to 1000x its weight in water. Draws moisture from the environment into your skin. Found naturally in your skin but declines with age.

Who should use this: If your concern is dehydrated skin, dry skin, fine lines from dehydration, or all skin types, this ingredient addresses that directly. 0.1-2%. Low molecular weight penetrates deeper. High molecular weight sits on top and plumps. Most products use a mix.

Key ingredients

Niacinamide, a form of Vitamin B3, is also present. This superstar ingredient helps reduce oil production, strengthens the skin barrier, and can fade post-inflammatory hyperpigmentation. It's best for oily skin, large pores, and uneven skin tone. However, Niacinamide can cause flushing or tingling in sensitive skin, especially at concentrations above 5%. If you experience stinging, the concentration might be too high for your skin. Sodium Hyaluronate is included for hydration, helping to offset any potential dryness from the exfoliation.

Who should use this

This product is best suited for individuals with oily, combination, or normal skin types struggling with whiteheads, closed comedones, and a dull complexion. Those looking to improve skin texture and achieve a more even skin tone will also benefit. If you are new to chemical exfoliation, this could be a good starting point due to its relatively gentle nature compared to some stronger AHA formulations.

Who should skip this

Individuals with very sensitive, dry, or compromised skin barriers should approach this product with caution, or skip it entirely. If you are already using other active ingredients like retinoids or Vitamin C, avoid using this product in the same routine to prevent over-exfoliation and irritation. Pregnant women should consult with their doctor before using any AHA product; if approved, remember to use a 100% mineral sunscreen daily.

How to use

Apply this liquid at night, after cleansing and toning. Dispense a small amount onto a cotton pad or directly into your hands and gently pat it onto your face, avoiding the eye and lip areas. Follow with a hydrating serum and moisturizer. Start by using it 2-3 times per week and gradually increase frequency if tolerated. Always apply a broad-spectrum SPF the following morning, as AHAs can increase sun sensitivity.

There are currently no reviews available for the COSRX AHA 7 Whitehead Power Liquid on sskin.care. Therefore, we cannot summarize user sentiment at this time.

Price context

At Rs1350, the COSRX AHA 7 Whitehead Power Liquid is a reasonably priced chemical exfoliant, especially considering its brand reputation and formulation quality. While there are cheaper Indian glycolic acid options, they often lack the elegant texture and thoughtful ingredient combinations found in COSRX products. This product offers good value for those seeking a reliable and gentle AHA.

Final take

The COSRX AHA 7 Whitehead Power Liquid is a reliable and effective exfoliant for addressing whiteheads and improving overall skin texture. It's a strong contender for those looking to introduce an AHA into their routine, provided they understand the importance of sun protection and proper usage. I would recommend this for anyone with persistent whiteheads or dullness, particularly if they have oily or combination skin, and are seeking a product with a proven track record from a trusted brand.

Same ingredient, different brands

COSRX is not the only brand selling a other with glycolic acid. Here is what else exists at what price. Same active, different formulations. The choice comes down to texture, price, and what your skin prefers.
