Never layer Direct Acids - simply switch out your everyday Direct Acid on the days you want to use Sleep Glycolic in your evening routine. E.g You can use Press & Glow in your AM regime, Sleep Glycolic in the PM, then Press & Glow in the following AM regime.
Sleep Glycolic can be used with acid cleansers or treatments, for example Surface Radiance Cleanse.
Unfortunately, as a cosmetic brand we are unable to provide specific medical advice relating to our products. We would strongly advise speaking with your GP or Midwife so that they can give you an accurate recommendation. The full ingredients list for each of our products can be found on the product pages of the Medik8 website.
For general guidance, we would recommend that you avoid the following during pregnancy:
Vitamin A serums, including Intelligent Retinol, Crystal Retinal, any r-Retinoate and Night Ritual Vitamin A
Leave on salicylic acid (BHA) products, including Blemish Control Pads, Blemish SOS, Smooth Body Exfoliating Kit
Leave on peels, including Sleep Glycolic
This list is not exhaustive and must be used in conjunction with the advice from a medical professional.
We do not advise to use Sleep Glycolic during the day, as glycolic acid can make skin more sensitive to sun damage. Instead, use 2-3 times a week after cleansing in the evening. Follow with other serums and moisturiser. Always use SPF the morning after.
Sleep Glycolic is suitable for normal skin types - including congested skins, oily skin types, uneven textured skins and those prone to visible hyperpigmentation. This is a high concentration exfoliating acid product, and while we have minimised irritation for healthy skin types, those with inflammatory skin conditions are likely to find Sleep Glycolic to be too powerful, particularly on broken skin. It is not suitable for very sensitive skins, including inflamed acne, rosacea and eczema.
Yes, Sleep Glycolic can be used with vitamin A - you can find it in the Wrinkle Repair evening regime alongside Crystal Retinal. They can provide enhanced results when used in combination.
We would not recommend the use of Sleep Glycolic for new users phasing-in vitamin A. While the effects of vitamin A are optimised with the use of Sleep Glycolic, we would always advise users to allow their skin to get used to the prior before attempting to accelerate their results.
Once skin has gotten into the rhythm of using vitamin A nightly (once phase-in has been completed, or a couple of weeks of using a new strength) Sleep Glycolic is ideal for enhancing the visible anti-ageing benefits.
Exfoliating acids, including Sleep Glycolic, are completely safe to use in the summertime or on holiday, as long as you are applying a high protection sunscreen every day. We strongly recommend applying an ample amount of sunscreen like Physical Sunscreen or Advanced Day Total Protect the day after using Sleep Glycolic, as glycolic acid is known for making skin more sensitive to sun damage. If you are in direct sunlight, we recommend you reapply sunscreen every 2 hours.
