Cosrx Natural BHA Skin Returning A-Sol Essence has been fifteen years in development, and has been specially formulated to treat a wide range of skin issues. Made with natural ingredients, including 60% black bee propolis, this product gently removes excess oil from the skin, dramatically refining the appearance of pores to leaving skin looking smoother and healthier.

The BHA/AHA component of this essence dissolves any pollutants blocking your pores, while its sebum-reducing properties eliminate unwanted oils which can leave your skin with an unsightly shine. The healing and anti-bacterial qualities of propolis have long been recognised, with the black bee propolis which acts as the key ingredient in this cream working to create a barrier against impurities whilst sealing in moisture.

Directions for using Cosrx BHA Essence:

  1. Use both morning and night after washing your face and using your toner. Apply in gentle strokes over the most affected areas of the skin, especially where you get oil and enlarged pores.
  2. You can gently tap your face with your finger tips to increase the penetration efficiency and bring life to the skin.

How to fit Cosrx BHA Essence into your routine:

Begin by using your usual cleanser and toner, then apply the Natural BHA Skin Returning A-sol Essence. Follow with your usual face moisturiser.

Top tips for using Cosrx BHA Essence for oily skin:

  • If troubled with excessive sebum production from the pores, you can benefit greatly from this skin product. Coat a cotton pad with A-sol and apply on oily areas for around 10 minutes. It will dissolve skin dead cells and provide deep hydration - the key to stopping excess oil production.
  • Storing this BHA Essence in a cool fridge can amplify the soothing and pore-reducing effect and also provide a highly refreshing sensation.
  • For very oily skin types, you can use this BHA Essence instead of your usual toner.
