AHA vs BHA:
The Skincare Acids Explained

AHA, short for Alpha Hydroxy Acid, is a group of water-soluble acids often derived from natural sources such as fruits, milk or sugar cane. AHAs work by gently breaking down the bonds between dead skin cells on the skin's surface, encouraging them to shed and allowing healthier, more radiant-looking skin to emerge. If you're dealing with rough texture, dryness, dullness or uneven skin tone, AHAs can help improve your complexion by promoting smoother skin and boosting natural glow. Common types of AHA include Glycolic Acid, known for its deep exfoliation; Lactic Acid, which is hydrating and gentle; and Citric Acid, sometimes used for brightening. Understanding what is AHA and BHA helps you decide when to reach for each one in your routine.

Both AHAs and BHAs help exfoliate the skin and improve texture, but they share several key benefits that make them effective for different skin types. They both:

• Promote the removal of dead skin cells, encouraging a smoother, fresher complexion and enhancing the overall appearance of the skin.
• Assist in minimising the visibility of enlarged pores by clearing out excess oil, dirt and dead skin cells that can contribute to pore blockages.
• Contribute to the reduction of signs of ageing, such as fine lines and wrinkles, by stimulating cell turnover and promoting Collagen synthesis.
• Support skin tone evening, addressing concerns like discolouration, hyperpigmentation and dark spots, resulting in a more uniform complexion.
• Enhance overall skin texture, leaving the skin feeling smoother and more refined.
• Promote pore unclogging, which can help prevent blemishes and blackhead formation by addressing the build-up of oil and impurities within the pores.

While AHAs and BHAs both help to exfoliate the skin and improve texture, the main difference between AHA and BHA lies in how and where they work. AHAs are best known for smoothing the skin's surface, while BHAs go deeper to unclog pores, which is why people often compare AHA vs BHA when building a routine.

• AHAs are ideal for addressing dullness, uneven tone, dryness and early signs of ageing. They exfoliate the outermost layer of the skin to promote a fresher, more radiant appearance.
• BHAs, such as Salicylic Acid, penetrate into the pores, making them particularly effective for helping to manage oiliness, blackheads, blemishes and enlarged pores. Together, they offer complementary benefits – and for many skin types, using both (in rotation or as part of a balanced formula) can deliver clearer, smoother and more even-looking skin. If you're unsure whether to choose AHA or BHA, think about whether surface glow or deep pore care is your main goal.

Start by cleansing with the NIVEA Derma Skin Clear Wash Gel, formulated with Salicylic Acid (BHA), Sea Salt and Niacinamide. It deeply cleanses, helping to remove excess oil, dirt and impurities from your skin while clearing the pores to help prevent breakouts and blackheads. Gentle on the skin, it mattifies and refines the texture for clear and smooth skin.

Next, use the NIVEA Derma Skin Clear Scrub, enriched with Salicylic Acid (BHA), Sea Salt and Niacinamide. It supports your skin's natural renewal process, refines pores and reduces blackheads and blemishes without drying out, to provide a clearer skin complexion.

After exfoliating or cleansing, apply the NIVEA Derma Skin Clear Toner, which contains Salicylic Acid (BHA). It's a refreshing toner that helps balance blemish-prone skin and further cleanse the pores. With Salicylic Acid and Niacinamide, this toner helps tighten pores and remove dead skin cells. It also controls excess oil production, which can contribute to breakouts and skin congestion. Regular use of this toner can enhance your skin's clarity, providing a smoother, more even texture.

After toning, use the NIVEA Derma Skin Clear Chemical Exfoliator to provide gentle exfoliation with AHA. This product helps refine skin texture and target blemishes, and it's perfect for nightly use. Simply apply it after toning, without rinsing, to help keep your skin smooth and clear without over-drying.

• Apply a broad-spectrum sunscreen with at least SPF 30 every morning, even on cloudy or indoor days. UV rays can penetrate clouds and, to some extent, even windows – and consistent SPF use is your best defence.
  
  
• Use exfoliating acids in your night-time routine, especially if you're new to acids or have sensitive skin. This minimises immediate sun exposure after application and allows your skin to recover overnight.
  
  
• Make sunscreen a daily habit and non-negotiable when using chemical exfoliants like AHAs or BHAs. Regular SPF use not only protects your skin but also enhances the results of your exfoliating routine.
