Why Lactic Acid is the UK's Ultimate Skincare Hero for 2025
Lactic Acid: Your Ultimate Skincare Hero Revealed

In the bustling world of beauty, one ingredient is stepping out from the shadows to claim its rightful place as a skincare essential. According to renowned beauty columnist Sali Hughes, lactic acid is the ultimate multitasking hero, offering a gentler yet highly effective alternative to its more famous cousin, glycolic acid.

The Multifaceted Power of Lactic Acid

So, what makes this particular alpha hydroxy acid so special? Hughes highlights its unique ability to deliver multiple benefits without the irritation often associated with stronger acids. Its larger molecular size means it exfoliates the skin's surface without stripping or stinging, making it suitable for even sensitive complexions.

Beyond simple exfoliation, lactic acid works on a deeper level. It can help stimulate the production of collagen and ceramides, which are crucial for firming, plumping, and protecting mature skin. For those with problematic skin, its antibacterial properties are a boon. Furthermore, it acts as a humectant, binding with water to keep all skin types optimally hydrated. The result? A brilliantly smooth texture and that coveted, unmistakable glow.

Top Product Picks for Every Budget

The good news for British consumers is that the market is now brimming with excellent lactic acid formulations. Hughes points to several standout products that have earned her approval.

For those seeking a potent treatment, Beauty Pie’s Youthbomb Extreme Retinal Triple Renewal Serum (£49 for members) is a top-tier choice. This creamy serum combines lactic acid with niacinamide, two potent retinoids, hyaluronic acid, and ceramides. Hughes noted its impressive smoothing effects, though she cautions that the retinoids mean it is not safe for use during pregnancy.

A firm favourite in her morning routine for the past 18 months is Clinique’s Moisture Surge Active Glow Serum (£44). This product masterfully blends glycerin, vitamin C, and lactic acid for instant hydration, radiance, and an even skin tone, offering fair value within the current market.

Budget-conscious shoppers need not miss out. Hughes recommends the Brightening Serum (£12.99) from Byoma, a fine-textured, hydrating formula with a dash of lactic acid that is particularly suitable for oilier skin types.

How to Incorporate Lactic Acid Into Your Routine

If you're happy with your current skincare lineup, adding a dedicated lactic acid treatment is simple. Hughes suggests a toner as an easy 'slot-in' step. Paula’s Choice 6% Mandelic + 2% Lactic Acid (£14) is noted as one of the gentlest liquid exfoliants available. Simply apply with hands or a cotton pad before continuing with your usual regimen.

The benefits of lactic acid also extend beyond the face. It is exceptionally effective on the body, particularly for tackling flaky skin and the small, hard bumps of keratosis pilaris on thighs and upper arms. While several lotions are available, First Aid Beauty’s KP Smoothing and Brightening Body Lotion (£30) stands out. It contains an effective 10% lactic acid and, crucially, does a better job of masking the characteristic sour milk scent found in many similar products.

With its proven ability to exfoliate, hydrate, and illuminate, lactic acid is no longer just a supporting player. As Sali Hughes' curated selection shows, this versatile ingredient is a worthy hero for anyone in the UK looking to achieve healthier, more radiant skin in 2025.
