Different ‘Acids’ In Skincare: What Are They And What Are The Benefits? 

Although the weather may be dreary and dull, it doesn’t mean that your skin has to meet the same fate. As we embark into the new season with darker nights and frosty spells, environmental changes can take a toll on your complexion, leading to dryness and dullness. With a myriad of acids available on the skincare market, we take a look at the best hydrating and exfoliating options to keep your skin glowing throughout winter.

Different types of acids in skincare 

You might feel like you’re over-faced with options when it comes to looking at different acids in skincare. Despite the multitude of acids out there, don’t feel overwhelmed when it comes to pulling together your winter beautifying regime. Yes, there are a lot of skincare acids on the market, but there are only going to be a handful that are suitable for your skin concerns. Once you know what products work well together, and what acids are best for specific skin concerns, you can begin to build an individualised routine. Although there are countless options, you may want to begin with the more renowned skincare acids that target the most common skincare needs. 

Exfoliating acids 

Glycolic Acid

Glycolic acid is a type of alpha-hydroxy acid (AHA), and it works by breaking bonds between the outer layer of skin cells and the next skin cell layer. This eradicates dead skin cells to make the skin appear smoother and more even. Glycolic acid is so effective because it is water-soluble which helps to penetrate the skin deeper than the average AHA. Is glycolic acid for you, and would you benefit from adding it to your skincare routine? Well, it exfoliates dead skin cells, helps to even the skin tone, minimises pores, and fights blemishes. Offering deep exfoliation, glycolic acid promotes cell turnover, helping to prevent congestion.

Lactic Acid

Renew your skin! If you want your skin to feel fresh and radiant, then lactic acid is a great option. It exfoliates the skin’s surface and lifts away dead cells. Lactic acid is a natural AHA (Alpha Hydroxy Acid) that is derived from milk and fruit sugars. It has exfoliating properties which quickens cell turnover, subsequently improving the skin’s texture. Not only that, but lactic acid is both hydrating and anti-aging. It stimulates collagen production and maintains moisture retention levels, ideal for normal to dry skin types.

Salicylic Acid

If you have blemish prone skin, salicylic acid might be the one for you. It’s a beta hydroxy acid that works by exfoliating the skin to keep the pores clean. Whether you struggle with whiteheads or blackheads in skin breakouts, salicylic acid helps to clear any blemishes simultaneously helping to prevent further breakouts. This acid will penetrate deep into the pores, helping to loosen dead skin cells and clear congestion. If you suffer from acne, then you may have inflammation and redness on the skin. Salicylic acid will help to reduce the visible signs of skin irritation.

Hydrating Acids

Polyglutamic Acid

When it comes to hydrating acids, polyglutamic is a powerhouse. It’s gentle on the skin, very hydrating, and makes the skin flawless without irritation. It’s very similar to hyaluronic acid in the way that it hydrates the skin, but it hydrates in a different way. Whilst hyaluronic acid penetrates the skin, polyglutamic acid creates a film on the surface of the skin. This locks in the moisture for a glass-like skin finish. Due to it being water-soluble, it makes the perfect foundation primer! Both polyglutamic and hyaluronic acid work well to reduce fine lines and wrinkles, as they are so powerful in hydrating the skin. More on hyaluronic acid below. 

Hyaluronic Acid

It’s a magnet for moisture and the key skincare component to having plump, healthy skin. Do you experience dry skin, especially when we hit winter? Hyaluronic acid is a humectant with moisture binding properties. Here’s how: Just a single gram of hyaluronic acid has the incredible ability to hold up to six litres of water. Not only does hydrated skin look and feel healthier, but it benefits your complexion in the long term too. The more hydration that your skin has, the less likely you are to have wrinkles and fine lines. Rebecca Rutherford from Scratch Aesthetics explains why hyaluronic acid is so beneficial in the winter months:

“I feel adding hyaluronic acid to your skincare regime is imperative due to its hydrophilic properties where it attracts and binds to water. Therefore, it keeps the skin hydrated and for longer periods. 

It also ensures that the skin’s barrier is more effective at tackling dryness that can lead to, or trigger, other conditions if not targeted. This is especially important during the winter months with external triggers to dry skin such as persistent cold weather or indoor heating.” Rebecca Rutherford Browning, @scratchaesthetics.

Injectable skincare in your regime 

Injectable hyaluronic acid (HA) is a type of temporary dermal filler, which works to hydrate the skin. It gives immediate results whilst lasting for a considerable amount of time. Maintaining a traditional skincare routine can be time-consuming, with so many products to be applied at so many intervals throughout the day. Skin boosters require a 45-minute appointment every 6-12 months for top-up treatments, meaning that it’s a single step solution to the dewy skin you desire! The Next Generation Skin Booster, Seventy Hyal, works to replenish moisture lost due to environmental factors, whilst helping to maintain the skin’s hydration levels. 

Faye Showell, from Medax UK, shares her expertise in injectable skincare:

“I feel there is a lot of stigma surrounding injectable skin care. A lot of people are put off because they don’t understand how they work, or they see that needles are involved, and run for the hills. 

I think it’s really important we normalise injectable skin care treatments and spread awareness in order to reassure people they are actually super effective and can be very beneficial to our regular skin care regimes. Winter can be super harsh on our skin, especially with the cold weather, inside heating and our bodies adjusting to such a drastic drop in temperature. 

I find personally that hyaluronic acid really helps balance out my skin and adjust to the colder months without my skin suddenly becoming problematic or huge breakouts appearing overnight. Hyaluronic acid definitely softens the blow and helps with that!” –  Faye Showell, @medax_uk.

All you need to know about adding different acids to your skincare 

Our skin needs a little bit more attention when we transition through seasons. As we move away from Summer, it’s important to pay attention to the changing needs of our skin. It’s important to introduce any new activities into your skincare routine gradually to minimise the risk of irritation. As a rule, don’t mix AHAs, BHAs and retinol together when pairing acids. Prior to using acids on the skin, do a patch test and research the specific products that you’re using. Using too many different types of acids can have the adverse effect; as an example, if you use too many exfoliating acids, then you risk drying out the skin or affecting the skin’s natural barrier function. 

Whether your winter skincare regime consists of skin-enhancing serums or a cocktail of different actives, implementing acids into your routine is your one-way solution to supple skin – even during the winter months. Alternatively, opt for Next Generation Skin Booster, Seventy Hyal 2000 for a multi-step skincare routine in one efficient treatment.
