I've been using and repurchasing a wide variety of SF's serums over the past 5 years, and have repurchased the 5% Hydroxypinacolone Retinoate Serum three times already after working my way up through all the other vitamin A strengths. No irritation and beautiful results if used like SF recommends. Higly recommend! If I could I would add every product on the site to my cart!

The skin advice and recommended products are making a world of a difference on my skin

Excellent product, makes my skin feel soft and moiterized. So far I am loving it.

I love this foamy cleanser, it is really gentle and leaves my skin fresh. I’m happy with the product.

I love how this moisturiser leaves my skin so soft and glowing . Worth every penny 🩷

This is the best serum I have ever used. My skin feels and looks amazing. This was my second time buying it and I will continueusing it as part of my routine... Thanks Skin Functional

I use this together with alpha arbutin during the day.great combo for my skin

I have struggled with strawberry skin on my legs ,two weeks of using the product I can feel the difference on my skin,the texture is improving

Started incorporating this in my skincare routine two years ago,I use it twice a week and my skin feels great.

It works wonders for my extra dry skin due to an autoimmune disease. It keeps my skin moist for most of the day.

The Ultimate Breakout Moisturizer has become my holy grail! It feels luxe on the skin, providing deep hydration without being oily. It calms my sensitive, acne-prone skin and leaves me feeling refreshed and hydrated. Absolutely must for anyone with sensitive skin prone to breakout that still want the benefits of deep hydration.

This product is magical. I have never used such an effective product to clear up breakouts. It’s clear, so I feel comfortable applying it day and night. I spot treat stubborn pimples (mostly jawline and cheeks) as soon as they appear and it just stops them in their tracks. They don’t get any worse and just calm down and fade away over the next 1-3 days. It’s amazing. No dryness, irritation, flaking.

My skin feels hydrated, plump, nourished, glowing. It works well for my slightly dry skin, and my friend with oilier skin also loves it, saying it doesn’t trigger or worsen oil-production. I think this will be my go-to moisturiser for the foreseeable future.

This has made a huge difference to my skin texture, slowly reducing pigmentation and efficiently clearing up breakouts that I’d started getting on my cheeks. Truly a multi-tasker! My skin looks and feels healthy, plump and nourished even though there’s hard work being done by this product (unlike my experience with past products where you have to deal with side effects like dryness or redness, etc while trying to fix a skin concern).

I recently tried the 10% Azelaic Acid serum from SF for my sensitive, blemish-prone skin. After the first use, I noticed my pimples calming and fading (yay!) While results typically take several weeks, research shows that Azelaic Acid is excellent for combating rosacea. A little goes a long way, and I’m excited to see how my skin improves over time!
