Mediheal Hyaluronic Acid

Mediheal was founded in 2009 with dermatology clinics as its primary distribution channel. Its products were originally sold exclusively through Korean pharmacies and skin clinics, which shaped the brand's formulation priorities: efficacy, tolerance, and consistent results across skin types. The sheet mask line became a crossover retail product as Korean skincare expanded globally, but the clinical development approach - standardized serum concentrations, tested active-to-sheet compatibility - remains the production standard.

HA is central to this because it is a core ingredient in post-procedure skin care. After laser, chemical peel, or microneedling treatments, HA supports rapid barrier recovery without the irritation risk of acids or actives. Mediheal's Hyaluronic Moist Essence Mask became popular in clinics as a post-procedure recovery step, which is how it became a retail bestseller.

The Hyaluronic Moist Essence Mask is available in a 20ml single-sheet format. Each sheet is soaked in a HA-concentrated serum. Application takes 15 to 20 minutes; after removing the sheet, the remaining serum on the face is patted in without rinsing. This is Mediheal's most widely used mask and the one most suitable for daily or every-other-day use because the formula is gentle and non-irritating.

The sheet material is bio-cellulose or non-woven fabric depending on the sub-variant; both conform to the face and maintain serum contact across uneven areas like the nose bridge and jaw. At 20ml per mask, the serum volume is generous enough to leave a noticeable moisture-seal on skin after the masking period.

The Derma Modeling Pack Hyaluronic Acid 28g is a rubber (alginate) mask that comes as a dry powder. Mix with water to form a gel, apply to the face in a thick layer, and it sets into a rubber-like film within a few minutes. This format creates a stronger occlusive seal than a sheet mask, which drives HA deeper into the epidermis over the 15 to 20 minute contact period.

The modeling pack is typically used less frequently than a sheet mask - once or twice a week - due to the preparation time and the higher-intensity treatment effect. After removing the rubber mask (which peels off in one piece), skin appears noticeably more plumped and hydrated than after a standard sheet mask. It is particularly effective on very dehydrated or post-sun skin where deeper moisture delivery is needed.

The H.P.A. Ampoule Mask uses an ampoule delivery system rather than a plain serum-soaked sheet. H.P.A. stands for Hyaluronic acid + Peptides + Ampoule, a combination that pairs HA hydration with peptide repair in a high-concentration carrier. This is Mediheal's most treatment-oriented sheet mask format, suited for skin that needs both deep hydration and structural repair in one session.

Use the H.P.A. Ampoule Mask 2 to 3 times per week rather than daily, because the peptide concentration and ampoule delivery method are more intensive than the standard Essence Mask. After removal, no rinsing is needed; the residual serum on skin continues to absorb. It is one of the better Mediheal options for skin showing early signs of aging alongside dehydration.

The PEP Proatin Mask brings protein (proatin = protein ampoule) alongside HA into a mask format. Protein hydrolysates in skincare form a temporary film on the hair and skin surface that increases tensile strength and reduces breakage in hair; on the face, they support barrier function and provide a temporary smoothing effect. The PEP Proatin Mask targets skin that needs both hydration and structural surface reinforcement.

It is useful after periods of barrier disruption - over-exfoliation, prolonged cold exposure, or sensitization - when skin needs moisture plus a protein-based surface shield. Use it in the same way as the Essence Mask: apply to clean face, leave 15 to 20 minutes, remove and pat in remaining serum.

The Mediheal Moisture Soothing Sunscreen 50g carries HA in a sunscreen base, combining UV protection with the brand's hydration approach. A HA-enriched sunscreen reduces the drying effect that some SPF formulas produce on skin over a day of wear. It is positioned as a daily facial SPF for skin types that find standard sunscreens drying or uncomfortable to wear over extended periods.

Apply as the last step of a skincare routine, after serums and moisturizer and before makeup. The 50g size is the standard facial sunscreen tube size in Korea and covers roughly 60 to 90 days of daily full-face use if applied at the recommended 1/4 teaspoon equivalent amount.

The Vitalab Aid Moisturizing Berry Mask is a sub-line that combines HA with berry extracts for antioxidant support alongside moisture. It is a standard sheet format positioned for general use. Mediheal's Vitalab line is formulated for sensitive skin types that need antioxidant and moisture benefits without fragrance or heavy actives.

Beyond the masks and sunscreen, the Callus Gold Treatment Water Essence 30ml is a lightweight essence for foot callus care that includes HA for hydration of rough skin. The Vitamin Derma Ampoule Blemish Whitening 50ml brings vitamin-based brightening actives alongside HA, targeting both dehydration and uneven tone. Both are smaller-format, targeted products that complement a mask-centered Mediheal routine.

The Hyaluronic Moist Essence Mask and Vitalab Aid Moisturizing Berry Mask can be used daily without irritation - they are the everyday formats. The H.P.A. Ampoule Mask and PEP Proatin Mask are best used 2 to 3 times per week due to their higher active concentration. The Derma Modeling Pack should be used once or twice a week as a more intensive treatment.

Sheet masks sit best either before toner (as a serum pre-step) or as the last skincare step at night. After mask removal, do not rinse - pat in the remaining serum. If you use a sheet mask before toner, follow with toner and moisturizer. If you use it as the last step, no further products are needed unless the skin feels dry. Masks do not replace serums or moisturizers for daily use; they are supplementary treatments.
