Good Molecules Overnight Exfoliating Treatment Review

Good Molecules is an affordable skincare brand based in the US and available to the UK via Beautylish. I’ve been interested in the brand since last year and I have tried a few of their products. Today’s post will be an in-depth review of their Overnight Exfoliating Treatment.

The Overnight Exfoliating Treatment is a 10% AHA & BHA serum that promises to resurface and renew the skin for visibly glowing skin.

Good Molecules Overnight Exfolating treatment review


The 10% AHA and BHA is glycolic and lactic acids (AHA) and salicylic acid as the BHA. The directions are to use up to 3 times a week only. It has a natural scent.

I have had this serum for a while now, I use as directed once in a while when I need to shift texture on the skin or when it needs a little boost. I’m almost half-way down the bottle.

My skin is used to high acid content but I still feel a little sting after I use this. When I incorporate this into my routine, I don’t use any other acids or other active ingredients in order to reduce any potential irritation. I would add this to my PM routine only, use after cleansing, then perhaps use a hydrating mist afterwards and a hydrating serum. I use it for 3 days in a row only before switching back to my normal routine. I haven’t experienced any irritation with using the serum alone.

Results? This serum delivers on its promises. It leaves the skin smoother and more radiant. It helps to reduce texture on the skin. It stings but nowhere near what you would feel if you used The Ordinary’s 30% AHA BHA. This is a leave-on serum so there is no need to rinse off.


I REALLY like this serum. At 10% it’s high but it’s also a perfect serum if you want to move up from 5% AHAs. It is important to follow the instructions and use as directed. Storytime: ok so I also have the Honeymoon Glow serum from Farmacy which is 14% AHA. For some reason, I thought it would be fun to use the Good Molecules serum for 3 days take a 1-day break and use the Honeymoon Glow serum too. What did I get? A damaged skin barrier! My skin was dry with a crepe-like appearance with texture. SMH. I had to switch back to ONLY hydrating and soothing products and it took about 2 weeks for my skin to fully heal and go back to normal lol.

This is why I recommend to only use this as the only acid in your routine if you want to try this. To be clear, when I used it as directed I had no issues and I have been using it ever since that episode with no problems. It is only when I followed this serum with another high acid serum, is when I had issues which to be honest is not surprising.

I would definitely recommend the Good Molecules Overnight Treatment. At 10% you will get the renewing and re-surfacing benefits from the AHA and BHA as promised. It also helps to reduce texture and leave the skin radiant. It goes without saying that you would use this at night and you MUST use sunscreen in the AM. Use as directed. You can follow up with hydrating products after using to add hydration to the skin. If you have sensitive skin, please patch test first. If you have normal to combination skin like myself you will really like it but still patch test if you are not sure. If you are an experience acid user and love chemical exfoliation, then girl get this. I wouldn’t call this a dupe for Farmacy Honey Glow but it’s a lower percentage but you will get smoother skin which is what HG promises as well. It’s pretty comparable in terms of results. You don’t need both serums.

Lixir Skin AHA/PHA 10% Night Switch Review

I’m not new to the Lixir skin brand although my first experience was negative. Read my thoughts on their vitamin c paste here. I love acid serums so when I saw the AHA PHA 10 night serum I knew it was something I needed to try. This serum promises to gently exfoliate the skin for smoother skin.


I am very comfortable with using skincare acids even at higher percentages or a combo of acids. This AHA PHA blend at 10% promises to gently exfoliate the skin for smoother healthier skin. You are directed to use at night for 3 weeks then take a break OR switch to another night switch serum mixed with one of their moisturizers. I have been using mine neat, 3 times a week and I have experienced no irritation.

AHA PHA are acids both known to gently exfoliate the skin. 10% is a good conc for it to actively work. I remember feeling a tingling sensation when I first used it but subsequent use didn’t give that sensation.  I didn’t experience any burning or rashes with this. This is a very lightweight watery serum and I find it sinking into the skin with ease.  It offers some hydration but not a lot. I use this after a water mist and on nights I use this acid serum, I don’t combine it with any other acid. I usually layer a gel-cream afterwards or I have used it a few times with my Estée Lauder ANR. Lixir Skin AHA PHA is a blend of 3 acids: lactic (AHA) lactobionic (PHA) and phytic (AHA).

Results? I am in love with this! It’s a small but mighty serum and I find my skin has been smoother and appears healthier since adding this to the night routine. I really thought I would run out of the 15ml serum very quickly, but using only 2 to 3 pumps 3 times a week, it’s lasted longer than expected. I think I am going into my 3rd month and I have only gone past halfway.


This is a very well-formulated acid serum which is a blend of two of my fav acids at a percentage high enough to work but gentle enough to use. I’m not sure how sensitive skin will react to this. Although you are directed to mix with a moisturizer, I have been using mine neat and I have not had any issues but if you are going to use it this way, I would patch test first. You can also use this as a wash-off mask but I haven’t tried it yet, maybe I will before I finish the bottle.

The serum is good at exfoliation and I would recommend you stick to the 3x a week direction. It may look small but it lasts.

Please use acids with caution: stick to one leave-on acid product, e.g. serum or toner. There is no need to combine several acid products in one routine, for instance, an acid toner and cream especially if they are high concentration. Always use SPF 30 and above in the mornings no matter the weather (and preferably use a dedicated SPF, not an SPF moisturiser)

Nip Fab Glycolic Fix Radiance Shot Review

Nip Fab’s Glycolic Fix range is one of the best acid collections in the drugstore. I personally love the Glycolic Fix collection and I have tried many items from it. I have a quick review of the Nip Fab Glycolic Fix Radiance Shot I have had for a while now.

This promises luminosity, smoother skin and reduced pigmentation.


So I have had this serum for a very long time but I have been using it on and off. I wasn’t frequently using it because I could not see any benefits plus I did not like the fact that it was iridescent. I do not like gimmicky skincare and this serum has a blue tint which turns golden when massaged into the skin (if you don’t mind this then of course go for it). This is a smooth lightweight texture with a strong chemical scent. It sinks into the skin very quickly but I feel like it leaves a very faint shimmer on the skin.

It wasn’t the gimmicks that made me dislike this, I just felt like I didn’t see any benefits using this. They do not state the glycolic content of this serum however after checking the ingredient list, glycolic acid is the 2nd ingredient. I haven’t seen any difference in my pigmentation and my skin is smooth because I use a 7% AHA toner. The serum adds no hydration to my skin but doesn’t pil with other products.


I couldn’t finish the bottle because I disliked the serum so I have thrown it away. In all fairness, I used more than half of the bottle but I couldn’t bring myself to finish it! I have had this for a while, I actually got it when they were doing a £5 sale ages ago. I love glycolic acids but this serum did not benefit my skin. I also don’t appreciate gimmicky skincare but I will use a product if I felt like it was working, this serum didn’t do anything for me so I stopped using it to move unto something else!
