Product description

Exfoliating serum for refined skin texture

The Hyper Acid4 Serum combines four different acids for a comprehensive yet controlled exfoliation. AHA (glycolic and lactic acid) removes dead cells from the skin's surface, while BHA (salicylic acid) penetrates deep into the pores and dissolves sebum deposits. PHA has a particularly gentle and moisturizing effect, while LHA gently refines pore size and works to reduce inflammation.
Application

After cleansing and toning, apply 2–3 drops of serum to your face and gently massage in. Use at night, as skin may become more sensitive to sunlight. Be sure to apply sunscreen during the day. For best results, use 2–3 times a week and gradually incorporate it into your routine.

Which skin type is the serum suitable for?

This serum is primarily aimed at skin prone to impurities, enlarged pores, or an uneven complexion. Thanks to the combination of several acids, it is well suited for oily-looking and large-pored skin. If you have sensitive skin, you should gradually introduce it into your routine.
What makes the acid combination special?

AHAs, BHAs, PHAs, and LHAs complement each other in various ways. While some acids primarily work on the surface, others support pore cleansing and result in a smoother skin feel. This creates a versatile exfoliation effect in a single product.
How often can you use it?

It's best to start with a few applications per week and observe how your skin reacts. Especially with peels, a gradual introduction is advisable so that the skin can get used to the routine. Also, remember to use sun protection during the day.
What should you pay attention to in the routine?

It's best to combine the serum with a rather simple skincare routine so that your skin isn't unnecessarily overwhelmed. On days with acid treatments, rich, soothing products are often a good complement. If your skin reacts very sensitively, test the product carefully first.

Fourfold Acid Care for Smoother Skin

The serum combines AHA, BHA, PHA, and LHA in a balanced formula. This nourishes the skin's surface while also targeting pores and sebum deposits. For refined, fresh skin with modern K-Beauty exfoliation.

Refine pores with gentle exfoliation

The mixture of different acids makes this serum particularly exciting for skin prone to shine and blemishes. AHA and BHA are supplemented by milder ingredients like PHA and LHA to keep the treatment controlled. The result is a clear, structured routine with a trending factor.

Light texture for daily routine

Thanks to its serum formula, the product can be easily integrated into your skincare routine. It is a good choice if you are looking for exfoliating care that doesn't feel too heavy. Such a multi-acid serum is particularly popular in minimalist skincare routines.

K-Beauty Skincare for Troubled Skin

If you're looking for a serum with multiple exfoliating acids, this formula is a powerful addition for oily skin with enlarged pores. It promotes a more even skin texture and fits well with current K-Beauty trends around glass skin and pore care. This is how you bring more clarity to your routine.
