FAQs

Lactic Acid is a naturally occurring water-soluble alpha hydroxy acid (AHA) which the body produces when it breaks down glucose into a fuel source when the tissues aren't sufficiently oxygenated. It's 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's typically found in cleansers, exfoliants and Serums, which promote its surface-level exfoliating properties, as well as its hydrating and anti-aging properties. Lactic Acid also helps in maintaining the slightly acidic pH of the skin, supporting the natural moisture barrier.

Lactic Acid Benefits for Skin

1. Exfoliation and cell turnover

Lactic Acid plays a role in removing dead skin cells on the outermost surface by breaking down the bonds that hold the dead skin cells together. This leads to their shedding, which reveals fresher, new skin cells underneath. Over time, regular exfoliate with Lactic Acid may promote a smoother complexion and improved skin texture.

2. Hydration and moisture retention

Thanks to its humectant properties, Lactic Acid draws in and retains moisture, which improves the skin's flexibility. It can also help to preserve the skin's natural moisture barrier with ceramides, which further improves moisture retention, making it suitable for people with Dehydrated skin.

3. Balancing skin tone

A skin tone is considered uneven if there are patches of hyperpigmentation, dark spots or Redness. While all of these factors are completely natural and unnecessary 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.

4. Collagen stimulation

Collagen is an important component of 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 skin.

5. Better product penetration

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 leads to deeper penetration and potentially more effective results.

6. Reduce symptoms of acne

Lactic Acid may help to alleviate symptoms of Acne. Its exfoliating properties can help to lift dead skin cells that may otherwise clogged pores and cause Acne.

Lactic acid for skin:
Uses and application

Lactic Acid is available for a wide range of applications which take advantage of its various benefits. In lower concentrations, it may be found in cleansers, face toner and moisturisers, while higher concentrations may be used in targeted active products such as Serum.

It's 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 know about the recommended use frequency. The NIVEA Derma Skin Clear Scrub for instance, whose Skin compatibility 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 sun cream to any affected areas. The same applies for any form of chemical exfoliant, which will typically increase your skin's sensitivity to the sun. It's 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 Lightweight formula is sweat resistant, suitable for application underneath make-up, and absorbs immediately for an invisible finish.

Lactic acid for skin - Considerations

1
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.

2
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 NIVEA Derma Skin Clear Scrub – along with all other products in the nivea derma skin clear range – is suitable for vegans.

3
Sensitivity:
Though Lactic Acid is considered one of the milder AHAs, usage of higher quantities may cause sensitive skin reactions 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.

Facts overview

Lactic acid in skincare

Lactic Acid is a naturally occurring water-soluble alpha hydroxy acid (AHA) found in fermented foods. It's also produced by the body lacking oxygen to produce 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 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

Below is our recommended skincare routine which includes products from the NIVEA Derma Skin Clear range, formulated specifically for blemished skin that is prone to breakouts.

1
Cleanse
Begin your routine with an effective face cleanser. The NIVEA Derma Skin Clear Wash Gel gently removes makeup and impurities and cleans deep inside pores to help prevent blemishes and spots 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.

2
Scrub
To go one step beyond regular cleansing and further refine your skin texture, occasionally switch the cleanser for a scrub such as the NIVEA Derma Skin Clear Anti-Blemish Scrub. It's 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.

3
Tone
Round off the cleansing stage of your routine by applying a gentle, salicylic acid face toner. The NIVEA Derma Skin Clear Toner can help to rebalance the skin’s natural pH level, control oiliness and Hydrate the skin without clogging pores.

4
Exfoliate
In your night routine, apply a concentrated face exfoliator to stimulate the renewal of old, damaged skin cells and further clear out the pores. The NIVEA Derma Skin Clear Chemical Exfoliator is formulated with salicylic acid, niacinamide and glycolic acid to visibly reduce breakouts and blemishes. Leave overnight for the best results.

Summary

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 balancing 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.

FAQs

How often you use Lactic Acid will depend on your skin's tolerance and the product's concentration. For beginners, it is recommended to start with low-dosed products, once a week for instance, before moving to more frequent usage, such as multiple times a week, depending on the product recommendations and the targeted face location. The NIVEA Derma Skin Clear Scrub, which contains Lactic Acid, is suitable for use 2–3 times a week.

It is always best to avoid mixing products and ingredients without knowing if they could react together. Notably, avoid using high concentrations of Lactic Acid in combination with other skin resurfacing ingredients such as retinol as this may lead to over-exfoliation.
Instead, use a formula containing multiple mixed ingredients, whose Skin compatibility and stability have been verified. If you're using different care products in your routine, leave a few minutes interval in between each application in order to avoid possible interaction.

Whether or not Lactic Acid is suitable for vegans depends on its source. Traditional Lactic Acid is derived from animal by-products, such as milk. However, many modern skincare products utilise Lactic Acid sourced from plant-based materials, making it vegan-friendly. Always check product labels or contact the manufacturer to ensure that the Lactic Acid used in your skincare product aligns with your vegan lifestyle. The NIVEA Derma Skin Clear Scrub is suitable for vegans.
