6 Benefits of
Lactic Acid in Skincare
Lactic Acid is a naturally occurring, water-soluble alpha hydroxy acid (AHA) that the body produces when it breaks down glucose into an energy source in situations where tissues are not sufficiently oxygenated. It is also found in a range of fermented foods such as dairy products, pickled vegetables and bread, among others. In skincare, Lactic Acid is renowned for its ability to remove dead skin cells and improve skin texture.
For this reason, it is typically found in cleansers, exfoliants and serums, which make use of its surface-level exfoliating properties as well as its hydrating and anti-ageing properties. Lactic Acid also helps to maintain the slightly acidic pH of the skin, supporting the natural moisture barrier.
What does lactic acid do
for skin?
Lactic Acid plays a role in removing dead skin cells on the outermost surface by breaking down the bonds that hold these dead skin cells together. This leads to their shedding, revealing fresher, new skin cells underneath. Over time, regular exfoliation with Lactic Acid may promote a smoother complexion and improved skin texture.
Thanks to its humectant properties, Lactic Acid draws in and retains moisture, which helps improve the skin's flexibility. It can also help to support the skin's natural moisture barrier together with ceramides, which further improves moisture retention – making it suitable for people with dehydrated skin.
Skin tone is considered uneven if there are patches of hyperpigmentation, dark spots or redness. While all of these factors are completely natural and nothing to worry about (do not hesitate to consult a doctor in case of doubts), their appearance might be reduced through regular use of Lactic Acid. This is in part due to Lactic Acid's exfoliating properties, but can also be linked to the fact that it could help to reduce the production of melanin, which is responsible for skin pigmentation.
Collagen is an important component of the skin, helping to maintain elasticity and firmness. As we age, collagen production typically slows down, leading to the natural occurrence of fine lines and wrinkles. Additionally, its exfoliating properties can assist in the regeneration of new skin cells and increase the production of collagen and Elastin, which can lead to fuller, plumper-looking skin.
The exfoliant properties of Lactic Acid can also help to increase the penetration of other skincare products. This is because the accumulation of dead skin cells can form a barrier against products, so their removal can lead to deeper penetration and more effective results.
Lactic Acid may help to alleviate symptoms of acne. Its exfoliating properties can help to lift dead skin cells that may otherwise clog pores and contribute to acne.
Lactic acid for skin:
Uses and application
Lactic Acid is available in a wide range of applications which take advantage of its various benefits. In lower concentrations, it may be found in cleansers, toners and moisturisers, while higher concentrations may be used in targeted active products such as serums.
It is advisable not to use high concentrations of Lactic Acid too often. Excessive use could lead to over-exfoliation, which may disrupt the skin's natural barrier. Always check the product label to find out the recommended frequency of use. The Derma Skin Clear Scrub, for instance, whose skin tolerance has been dermatologically tested, is recommended 2 to 3 times a week.
Whenever you do use high concentrations of Lactic Acid, make sure to apply sunscreen to any affected areas. The same applies to any form of chemical exfoliant, which will typically increase your skin's sensitivity to the sun. It is a good idea to get into the daily habit of applying SPF after completing your morning skincare routine.
The NIVEA SUN UV Face Specialist Triple Protect Sun Fluid SPF 50+ is ideal for those looking to add an effective SPF into their routine. Its light formula is sweat-resistant, suitable for application underneath make-up, and absorbs immediately for an invisible finish.
- Pregnancy:
A woman's skin may be more sensitive and reactive during pregnancy due to hormonal changes. Lactic Acid is generally considered safe for topical use; however, pregnant women should exercise caution and consult a dermatologist before using products containing higher concentrations of Lactic Acid. In any case, always be sure to check the package instructions before use.
- Veganism:
It is possible to obtain Lactic Acid from a variety of sources, including plants and animals. Vegan alternatives to conventional skincare products often use plant-derived Lactic Acid. If you’re unsure whether a specific ingredient in your chosen product is plant-derived or not, contact the manufacturer. The Derma Skin Clear Scrub – along with all other products in the Derma Skin Clear range – is suitable for vegans.
- Sensitivity:
Though Lactic Acid is considered one of the milder AHAs, usage of higher quantities may cause skin sensitivity in those who are prone to experiencing it. Rest assured that NIVEA products undergo rigorous dermatological testing to ensure they are safe for your skin.
Lactic acid in skincare
Lactic Acid is a naturally occurring, water-soluble alpha hydroxy acid (AHA) found in fermented foods. It is also produced by the body when oxygen is lacking, to generate more energy via the breakdown of glucose.
In skincare, Lactic Acid is renowned for its ability to remove dead skin cells, improve skin texture, and help maintain the skin's natural moisture barrier. Lactic Acid is commonly used in cleansers, exfoliants and serums, where it mainly acts on the surface level to exfoliate dead skin cells while helping the skin to remain pH-balanced.
The NIVEA Derma Skin Clear range offers effective cleansing products – in particular, the Anti-Blemish Scrub also contains Lactic Acid for a well-rounded skincare routine.
Building an effective
Cleansing Routine
Lactic Acid is often found in cleansers, toners and serums that make use of its humectant and exfoliant properties. But when it comes to building an effective routine, where do you start? Below is our recommended routine, which includes products from the NIVEA Derma Skin Clear range, formulated specifically for blemish-prone skin.
- Cleanse
Begin your routine with an effective cleanser. The Derma Skin Clear Wash Gel gently removes make-up and impurities and cleans deep inside pores to help prevent blemishes from appearing. After dampening your face, gently massage in the cleanser while taking care to avoid the eye area, and then rinse off with warm water.
- Scrub
To go one step beyond regular cleansing and further refine your skin, occasionally switch the cleanser for a scrub such as the Derma Skin Clear Anti-Blemish Scrub. It is formulated with salicylic acid and niacinamide, and also contains Lactic Acid. Using this scrub will help to reduce blackheads and whiteheads without drying out the skin.
- Tone
Round off the cleansing stage of your routine by applying a gentle salicylic acid toner. The Derma Skin Clear Toner can help to rebalance the skin’s natural pH level, control oiliness and hydrate the skin without clogging pores.
- Exfoliate
In your night routine, apply a concentrated exfoliator to stimulate the renewal of old, damaged skin cells and further clear out the pores. The Derma Skin Clear Chemical Exfoliator is formulated with salicylic acid, niacinamide and glycolic acid to visibly reduce blemishes. Leave on overnight for the best results.
Lactic acid benefits for skin:
Takeaway
Lactic Acid is a naturally occurring alpha hydroxy acid (AHA) that the body produces when it breaks down glucose molecules. Regular use of Lactic Acid promotes exfoliation and cell turnover, hydration and moisture retention, while also helping to balance skin tone and stimulating collagen production. For those following a vegan lifestyle, non-animal Lactic Acid alternatives are available. Incorporating Lactic Acid into a well-rounded skincare routine may lead to visibly improved skin texture and tone.
